Description:
FIELD OF THE INVENTION 
     This can relate to systems and methods for ejecting removable modules from electronic devices. 
     BACKGROUND OF THE DISCLOSURE 
     To enhance the use of electronic devices (e.g., cellular telephones), ejectable component assemblies may be used to couple removable modules (e.g., subscriber identity module (“SIM”) cards) to electrical components of the electronic devices. Some known ejectable component assemblies include a tray for receiving a removable module, and a connector within a housing of the device for receiving the tray as it is inserted through an opening in the housing. The connector may retain the tray such that contacts of the module may be electrically coupled to a circuit board or other electrical component of the device. 
     Some known ejectable component assemblies also include an ejector mechanism for ejecting the tray from the connector and, thus, from the housing of the device. Such an ejector mechanism often takes up valuable real estate within the housing of the device. Moreover, a portion of such an ejector mechanism often requires a user to interact with the ejector mechanism through an opening in the housing that may allow debris to enter the housing and impair the function of the device. 
     SUMMARY OF THE DISCLOSURE 
     Systems and methods for ejecting removable modules from electronic devices are provided. 
     For example, in some embodiments, there is provided an ejectable component assembly that may include any suitable assembly operative to insert into an electronic device, retain within the electronic device, and/or eject from the electronic device a removable module, such as a subscriber identity module (“SIM”) card. The ejectable component assembly can include a tray that may hold the removable module, and a connector within the electronic device that may receive, retain, and release the tray and module. Moreover, the ejectable component assembly may include an ejector mechanism for at least partially ejecting the tray and module from the connector. 
     The ejector mechanism may be configured to change between a first ejector mechanism state and a second ejector mechanism state. The first state may be configured to receive the tray and module into the ejectable component assembly, and the second state may be configured to at least partially eject the tray and module from the ejectable component assembly. The ejector mechanism may be biased to remain in either its first or second states absent any external forces acting on the ejector mechanism. The ejector mechanism may include a user interface portion and a tray interface portion, and each interface portion may include a first end fixed to the device and a second end coupled to the second end of the other interface portion. Tension between the fixed first ends may bias the ejector mechanism to alternate between its two ejector mechanism states when the ejector mechanism receives either a user input force to eject the tray and module from the connector or a tray input force to insert the tray and module into the connector. 
     In some embodiments, the ejector mechanism may include a user interface portion and a tray interface portion that may be coupled to the user interface portion. The user interface portion may be configured to change between a first user interface state of the first ejector mechanism state and a second user interface state of the second ejector mechanism state, and the tray interface portion may be configured to change between a first tray interface state of the first ejector mechanism state and a second tray interface state of the second ejector mechanism state. The user interface portion may receive a user input force through a user interface opening in a housing of the electronic device, which may cause the user interface portion to change from one of its two user interface states to the other. This change of user interface states may cause a similar change of the tray interface portion from one of its two tray interface states to the other, which may cause the tray interface portion to apply an ejection force onto the tray for at least partially ejecting the tray and module from the ejectable component assembly through a module opening in the housing of the electronic device. 
     In some embodiments, there is provided an electronic device that may include a housing, a connector positioned within the housing, and an ejector mechanism. The ejector mechanism may include a user interface portion and a tray interface portion. The user interface portion may include a first user interface end coupled to a first location within the housing and a second user interface end. The tray interface portion may include a first tray interface end coupled to the second user interface end and a second tray interface end coupled to a second location within the housing. The user interface portion may be configured to change from a first user interface state to a second user interface state when a user input force is applied to the user interface portion. In response to the change of the user interface portion from the first user interface state to the second user interface state, the tray interface portion may be configured to apply an ejection force onto a removable entity for at least partially ejecting the removable entity from the connector. 
     In some other embodiments, there is provided an electronic device that may include a housing having a first wall with a module opening through the first wall. The electronic device may also include an ejector mechanism positioned within the housing. The ejector mechanism may include a user interface portion and a tray interface portion. The user interface portion may include a first user interface end and a second user interface end. The tray interface portion may include a first tray interface end coupled to the second user interface end and a second tray interface end. The tray interface portion may be configured to change from a first tray interface state to a second tray interface state when a removable entity input force is applied to the tray interface portion by a removable entity during insertion of the removable entity into the housing through the module opening. The user interface portion may be configured to change from a first tray interface state to a second tray interface state in response to the change of the tray interface portion from the first tray interface state to the second tray interface state. Moreover, the user interface portion may be configured to receive a user input force through the housing. 
     In yet some other embodiments, there is provided an ejector mechanism for ejecting a removable entity from a connector. The ejector mechanism includes a user interface portion and a tray interface portion. The user interface portion may include a first user interface end and a second user interface end. The tray interface portion may include a first tray interface end coupled to the second user interface end and a second tray interface end. The user interface portion may be configured to move from a first user interface position to a second user interface position when a user input force is applied to the user interface portion. The tray interface portion may be configured to apply an ejection force onto the removable entity for at least partially ejecting the removable entity from the connector in response to the movement of the user interface portion from the first user interface position to the second user interface position.

     DETAILED DESCRIPTION OF THE DISCLOSURE 
     Systems and methods for ejecting removable modules from electronic devices are provided and described with reference to  FIGS. 1-17 . 
     The following discussion describes various embodiments of an electronic device that may include at least one ejectable component assembly. The term “electronic device” can include, but is not limited to, music players, video players, still image players, game players, other media players, music recorders, video recorders, cameras, other media recorders, radios, medical equipment, calculators, cellular telephones, other wireless communication devices, personal digital assistants, remote controls, pagers, laptop computers, desktop computers, tablets, servers, printers, or combinations thereof. In some cases, the electronic device may perform a single function (e.g., an electronic device dedicated to playing music) and in other cases, the electronic device may perform several functions (e.g., an electronic device that plays music, displays video, stores pictures, and receives and transmits telephone calls). 
     The electronic device may generally be any portable, mobile, hand-held, or miniature electronic device so as to allow a user, for example, to listen to music, play games, record videos, take pictures, and/or conduct communications operations (e.g., telephone calls) wherever he or she travels. Some miniature electronic devices may have a form factor that is smaller than that of hand-held electronic devices, such as an iPod™ available by Apple Inc. of Cupertino, Calif. Illustrative miniature electronic devices can be integrated into various objects that include, but are not limited to, watches, rings, necklaces, belts, accessories for belts, headsets, accessories for shoes, virtual reality devices, other wearable electronics, accessories for sporting equipment, accessories for fitness equipment, key chains, or any combination thereof. Alternatively, electronic devices that incorporate an ejectable component assembly may not be portable at all. 
       FIG. 1  is a perspective view of an illustrative electronic device  10  that may include an ejectable component assembly in accordance with some embodiments of the invention. Electronic device  10  can include at least one user input component assembly  12  that may allow a user to interface with device  10 , at least one device output component assembly  14  that may provide the user with device generated information, at least one ejectable component assembly  16  that may allow a user to insert and eject a removable module into and from device  10 , and a protective housing  18  that may at least partially enclose one or more of the input, output, and ejectable component assemblies of device  10 . Housing  18  may be any suitable shape and may include any suitable number of walls. In some embodiments, as shown in  FIG. 1 , for example, housing  18  may be of a generally hexahedral shape and may include a top wall  18   t , a bottom wall  18   b  that may be opposite top wall  18   t , a left wall  18   l , a right wall  18   r  that may be opposite left wall  18   l , a front wall  18   f , and a back wall  18   k  that may be opposite front wall  18   f . Each wall of housing  18  may have an inner surface  18   i  and an outer surface  18   o.    
     Component assemblies  12  and  14  can include any type of component assembly operative to receive and/or transmit digital and/or analog data (e.g., audio data, video data, other types of data, or a combination thereof). Input component assembly  12  may include any suitable input mechanism, such as, for example, one or more sliding switches, buttons, keypads, track balls, joysticks, dials, scroll wheels, touch screen displays, electronics for accepting audio and/or visual information, antennas, infrared ports, or combinations thereof. Output component assembly  14  may include any suitable output mechanism, such as, for example, one or more audio speakers, headphones, audio line-outs, visual displays, antennas, infrared ports, rumblers, vibrators, or combinations thereof. It should be noted that one or more input component assemblies  12  and one or more output component assemblies  14  may sometimes be referred to collectively herein as an input/output (“I/O”) interface or I/O component assembly. It should also be noted that input component assembly  12  and output component assembly  14  may sometimes be a single I/O component assembly, such as a touch screen that may receive input information through a user&#39;s touch of a display screen and that may also provide visual information to a user via that same display screen. 
     Ejectable component assembly  16  may include any suitable assembly that may be operative to insert into device  10 , retain within device  10 , and/or eject from device  10  a removable module  30 . Removable module  30  may include, for example, any suitable type of integrated circuit card (“ICC”), chip card, memory card, flash memory card, microprocessor card, smart card, such as a subscriber identity module (“SIM”) card (e.g., a mini-SIM card or a micro-SIM card), or combinations thereof. In some embodiments, removable module  30  may contain electronic circuitry (e.g., on the bottom of module  30  (not shown)), from which electronic device  10  may read data and/or to which electronic device  10  may write data. 
     Ejectable component assembly  16  can include a module tray  20  that may be at least partially insertable into device  10  (e.g., in the direction of arrow I) and ejectable from device  10  (e.g., in the direction of arrow O) via a module housing opening  19  that may be provided through housing  18 . Module housing opening  19  may be formed through any suitable portion of housing  18  for providing tray  20  and/or module  30  access into housing  18  of device  10 . For example, as shown in  FIG. 1 , module housing opening  19  may be provided through bottom wall  18   b  of housing  18 . It is to be noted that, although module housing opening  19  is shown in  FIG. 1  to be provided through bottom wall  18   b  that may define a width W of housing  18 , module housing opening  19  may be provided through any wall portion of housing  18 . For example, in some embodiments, module housing opening  19  may be provided through right wall  18   r  that may define a length L of housing  18 , which may be longer than width W of housing  18 . 
     Tray  20  of ejectable component assembly  16  may include a body portion  22  having a top surface  25   t  and a bottom surface  25   b  extending between a first tray end  21  and a second tray end  23 . Tray  20  may include an outer surface  21   x  at first tray end  21  that may provide a cosmetic surface for device  10  when tray  20  is inserted into device  10 . In some embodiments, outer surface  21   x  of tray  20  may be fashioned to be aesthetically pleasing to a user of device  10 , for example, by matching the color and/or material of surface  21   x  with that of the exterior surface of housing  18  about module housing opening  19 . First tray end  21 , second tray end  23 , and/or body portion  22  may define the periphery and/or walls of a module holder  24  of tray  20 . Module holder  24  may be operative to receive and hold removable module  30  with respect to tray  20  (e.g., when module  30  is inserted into holder  24  in the direction of arrow H). More particularly, module holder  24  may be operative to receive and hold removable module  30  with respect to an opening  26  that may be provided through a portion of tray  20 . Electronic circuitry of module  30  may align with opening  26  when module  30  is held by tray  20 . 
     Tray  20  may be formed as a single unitary component from any suitable material, such as plastic, glass, metal, ceramic materials, epoxies, composite materials, or the like. Moreover, tray  20  may be a single unitary component made by any suitable process, such as casting, molding, forming, forging, machining, extruding, and the like. Alternatively, tray  20  may be formed by joining at least two distinct tray portions. Holder  24  can be sized and shaped to substantially match the size and shape of module  30 , such that module  30  can be snap-fitted or otherwise releasably retained by holder  24 , and such that a portion of module  30  may be exposed through opening  26  of tray  20 . 
     As mentioned, tray  20  may be configured to receive and retain any suitable module  30  for insertion into device  10 , such as an integrated circuit card, chip card, memory card, flash memory card, microprocessor card, smart card, such as a SIM card, and the like. As shown in  FIG. 1 , for example, module  30  may include a top surface  31  and a bottom surface  33 . One or more electrical contacts (not shown) of module  30  may be exposed along bottom surface  33  of module  30 . Therefore, when module  30  is inserted into module holder  24  in the direction of arrow H, at least a portion of some or all of the electrical contacts on bottom surface  33  of module  30  may be exposed through opening  26  of tray  20 . For example, opening  26  may allow electrical circuitry of electronic device  10  to access data from one or more electrical contacts of module  30  through opening  26  when tray  20  and module  30  are partially or fully inserted into device  10  through module housing opening  19 . 
     Once module  30  has been loaded into holder  24 , tray  20  may be inserted into a connector that is at least partially internal to housing  18  of device  10 . For example, as shown in  FIGS. 2A-2E , ejectable component assembly  16  may also include a connector  40  for receiving and/or holding removable tray  20  at least partially within housing  18  of device  10  such that opening  26  of tray  20  may align with a module reader/writer of device  10 . For example, opening  26  of tray  20  may align with module reader/writer coupling circuitry  15  of device  10  when tray  20  is positioned within connector  40 , such that one or more electrical contacts of module  30  may be electrically coupled to coupling circuitry  15  through opening  26  when module  30  is held by tray  20 . 
     Connector  40  may be coupled to device  10  (e.g., by surface mount technology (“SMT”)) such that, when tray  20  is inserted into device  10  through opening  19  of housing  18  in the direction of arrow I, connector  40  may receive, guide, support, and/or retain tray  20  such that one or more electrical contacts of module  30  held by tray  20  may align with coupling circuitry  15  of device  10  through opening  26  of tray  20 . Although portions of housing  18  about opening  19  may at least initially guide the insertion of end  23  of tray  20  through opening  19  in the direction of arrow I (e.g., as shown in  FIG. 2A ), connector  40  can include retention members  42   a  and  42   b  for guiding tray  20  in the direction of arrow I once tray  20  has been at least partially inserted through opening  19  (e.g., as shown in  FIG. 2B ). Once tray  20  has been fully loaded into connector  40  (e.g., as shown in  FIG. 2C ), retention members  42   a  and  42   b  of connector  40  may interact with tray  20  to retain tray  20  in a functional position with respect to coupling circuitry  15  of device  10 , such that one or more electrical contacts of module  30  may align with coupling circuitry  15  of device  10  through opening  26  of tray  20 . For example, retention members  42   a  and  42   b  can retain a portion of tray  20  therebetween by exerting a biasing force of members  42   a  and  42   b  on that portion of tray  20 . As shown in  FIG. 2C , for example, retention members  42   a  and  42   b  may contact and exert their respective biasing connector forces (e.g., in the direction of respective arrows Ba and Bb) on tray  20  within respective grooved or notched portions  29   a  and  29   b  of tray  20 . It is to be understood, however, that connector  40  may be configured to receive, guide, and/or retain tray  20  and/or module  30  in any other suitable way using any other type of connector force or collection of connector forces on any suitable portion or portions of tray  20  and/or module  30 . 
     Surface  21   x  of tray end  21  of tray  20  can be any suitable shape such that it can be substantially flush with the portions of housing  18  about opening  19  when tray  20  is held in its functional or fully loaded position by connector  40 , thereby creating a smooth profile for that portion of device  10 . For example, as shown in  FIG. 2C , the external surface of housing  18  about opening  19  may be substantially straight and flat, and, therefore, so may be surface  21   x  of tray  20 . Alternatively, however, the surface of housing  18  about opening  19  may be substantially curved, and, therefore, so may be surface  21   x  of tray  20 . A curvature of surface  21   x  may be continuous with a curvature of housing  18  about opening  19  so as to create a smooth profile for that portion of device  10 . In other embodiments, surface  21   x  of tray  20  may be positioned within housing  18  when tray  20  is held in its functional or fully loaded position. 
     With continued reference to  FIGS. 2A-2E , ejectable component assembly  16  can also include an ejector mechanism  50  for at least partially ejecting tray  20  and/or module  30  from connector  40  and/or housing  18 . For example, ejector mechanism  50  may be provided for ejecting tray  20  from its fully loaded position of  FIG. 2C  to an at least partially ejected position of  FIG. 2D , and/or to a more completely ejected position of  FIG. 2E  (e.g., a position where retention members  42   a  and  42   b  may not have a retaining influence on tray  20 ). Ejector mechanism  50  may include a user interface portion  52  and a tray interface portion  58 . User interface portion  52  may extend between a first user interface portion end  51  and a second user interface portion end  53 . Tray interface portion  58  may extend between a first tray interface portion end  57  and a second tray interface portion end  59 . First end  51  of user interface portion  52  may be coupled to a fixed portion of device  10  (e.g., first end  51  may be coupled to a portion of housing  18  or another component of device  10  whose position is fixed with respect to housing  18 ) and second end  59  of tray interface portion  58  may be coupled to another fixed portion of device  10  (e.g., second end  59  may be coupled to a portion of housing  18  or another component of device  10  whose position is fixed with respect to housing  18 ), while second end  53  of user interface portion  52  may be coupled to first end  57  of tray interface portion  58 . In some embodiments, first end  51  of user interface portion  52  and second end  59  of tray interface portion  58  may be fixed with respect to one another or be at least partially constrained with respect to one another. Each one of first end  51  and second end  59  may be fixed to or have its movement at least partially constrained by any portion of device  10  (e.g., housing  18 , connector  40 , etc.). First end  51  may be fixed to or have its movement at least partially constrained/restrained by a first portion of device  10  at a first location within or with respect to housing  18 , and second end  59  may be fixed to or otherwise have its movement at least partially constrained/restrained by a second portion of device  10  at a second location within or with respect to housing  18 . 
     User interface portion  52  may be any suitable unitary component or collection of suitable components that may be capable of deflecting, deforming, bending, springing, pivoting, translating, rotating, responding, reacting, resulting, conforming, complying, traversing, relocating, moving, or otherwise changing between a first user interface state or position and a second user interface state or position. For example, user interface portion  52  may be made of any suitable material, such as rubber, plastic, metal, or any suitable combinations thereof. In some embodiments, user interface portion  52  may be a single component made of any suitable material while, in other embodiments, user interface portion  52  may be several distinct components. Different portions of user interface portion  52  may be flexible or rigid. For example, a first portion of user interface portion  52  at or near first end  51  may be rigid (e.g., for coupling to a portion of housing  18 ), while another portion of user interface portion  52  may be flexible (e.g., for bending or deflecting from the first user interface state to the second user interface state). 
     Tray interface portion  58  may be any suitable unitary component or collection of suitable components that may be capable of deflecting, deforming, bending, springing, pivoting, translating, rotating, moving, or otherwise changing between a first tray interface state or position and a second tray interface state or position. For example, tray interface portion  58  may be made of any suitable material, such as rubber, plastic, metal, or any suitable combinations thereof. In some embodiments, tray interface portion  58  may be a single component made of any suitable material while, in other embodiments, tray interface portion  58  may be several distinct components. Different portions of tray interface portion  58  may be flexible or rigid. For example, a first portion of tray interface portion  58  at or near second end  59  may be rigid (e.g., for coupling to a portion of housing  18 ), while another portion of tray interface portion  58  may be flexible (e.g., for bending or deflecting from the first tray interface state to the second tray interface state). 
     First end  57  of tray interface portion  58  may be coupled to second end  53  of user interface portion  52  in any suitable manner using any suitable coupling  55 . Coupling  55  may allow constrained relative motion between user interface portion  52  and tray interface portion  58 , such that user interface portion  52  may change between its first and second user interface states when tray interface portion  58  may change between its first and second tray interface states, and vice versa. For example, coupling  55  may be a ball and socket, a hinge pin, a compliant coupler, or any other suitable mechanism for coupling first end  57  of tray interface portion  58  to second end  53  of user interface portion  52 . Therefore, coupling  55  may allow for ejector mechanism  50  to change between a first ejector mechanism state (e.g., when each one of user interface portion  52  and tray interface portion  58  is in its respective first state) and a second ejector mechanism state (e.g., when each one of user interface portion  52  and tray interface portion  58  is in its respective second state). 
     User interface portion  52  may be configured to change from the first user interface state to the second user interface state when a user input force is applied by a user onto user interface portion  52  or in response to tray interface portion  58  changing from the first tray interface state to the second tray interface state. User interface portion  52  may also be configured to change from the second user interface state to the first user interface state when the application of a user input force onto user interface portion  52  is terminated or in response to tray interface portion  58  changing from the second tray interface state to the first tray interface state. Moreover, tray interface portion  58  may be configured to change from the first tray interface state to the second tray interface state when a tray input force is applied by tray  20  onto tray interface portion  58  or in response to user interface portion  52  changing from the first user interface state to the second user interface state. Tray interface portion  58  may also be configured to change from the second tray interface state to the first tray interface state when the application of a tray input force onto tray interface portion  58  is terminated or otherwise overcome, or in response to user interface portion  52  changing from the second user interface state to the first user interface state. 
     In some embodiments, in response to user interface portion  52  receiving a user input force and thereby changing from the first user interface state to the second user interface state, a resultant change of tray interface portion  58  from the first tray interface state to the second tray interface state may cause tray interface portion  58  to at least partially eject tray  20  from connector  40  and/or opening  19 . Additionally or alternatively, in some embodiments, in response to the termination of the application of a tray input force onto tray interface portion  58  (e.g., when tray interface portion  58  may overcome a tray input force), a resultant change of tray interface portion  58  from the second tray interface state to the first tray interface state may cause tray interface portion  58  to at least partially secure tray  20  to ejector mechanism  50  (e.g., to at least partially secure tray  20  in its functional or fully loaded position of  FIG. 2C ). 
     When tray  20  is held in its functional or fully loaded position within housing  18 , as shown in  FIG. 2C , for example, ejector mechanism  50  may be configured to interact with tray  20  either to actively retain tray  20  in its fully loaded position (e.g., as described in more detail with respect to the embodiments of  FIGS. 3A-7B ) or to passively allow tray  20  to remain in its fully loaded position (e.g., as described in more detail with respect to some of the embodiments of  FIGS. 8A-11 ). Then, as shown in  FIGS. 2C and 2D , for example, when a user input force is applied to a portion of user interface portion  52 , user interface portion  52  may be configured to change from the first user interface state to the second user interface state, which may cause tray interface portion  58  to change from the first tray interface state to the second tray interface state for at least partially ejecting tray  20 . For example, a first end  99  of a user input tool  98  may be inserted through a user interface opening  17  in housing  18  for applying a user input force in the direction of arrow UI onto a portion of user interface portion  52 . When this user input force is applied onto user interface portion  52 , user interface portion  52  may be configured to change from the first user interface state of  FIG. 2C  to the second user interface state of  FIG. 2D . When user interface portion  52  changes from its first state to its second state, the change may cause tray interface portion  58  to change from the first tray interface state of  FIG. 2C  to the second tray interface state of  FIG. 2D . For example, tray interface portion  58  may be configured to change from a relaxed state to a taut state, or vice versa, in response to a change of user interface portion  52  from its first user interface state to its second user interface state. This alteration of states by tray interface portion  58  may cause at least a portion of tray interface portion  58  to interact with tray  20  for at least partially ejecting tray  20  from connector  40  and/or from opening  19  in the direction of arrow O, as shown in  FIG. 2D . 
     When tray interface portion  58  changes from the first tray interface state to the second tray interface state, at least a portion of tray interface portion  58  may impart a first ejection force onto at least a portion of tray  20  that may be great enough to overcome any retention force applied by connector  40  on tray  20 , such that the first ejection force may at least partially eject tray  20  from connector  40 . For example, tray interface portion  58  of ejector mechanism  50  may be configured to impart a first ejection force onto tray  20  when tray  20  is held in its functional or fully loaded position by connector  40 , and this first ejection force may be great enough to overcome a retention force applied by retention members  42   a  and  42   b  of connector  40  on tray  20  (e.g., in the direction of arrows Ba and Bb), such that tray  20  may be at least partially ejected from connector  40  in the direction of arrow O (e.g., from the fully loaded tray position of  FIG. 2C  to the at least partially ejected tray position of  FIG. 2D ). 
     Then, when the application of the user input force on user interface portion  52  is terminated, user interface portion  52  may be configured to return from its second user interface state to its first user interface state, which may once again cause tray interface portion  58  to alternate states, which may in turn further eject tray  20 . For example, when first end  99  of user input tool  98  is at least partially withdrawn through user interface opening  17  in the direction of arrow U 0  for terminating the application of a user input force on a portion of user interface portion  52 , user interface portion  52  may be configured to return from its second user interface state of  FIG. 2D  to its first user interface state of  FIGS. 2C and 2E . This change of user interface portion  52  from its second user interface state to its first user interface state may cause tray interface portion  58  to change between its second tray interface state of  FIG. 2D  and its first tray interface state of  FIGS. 2C and 2E , which may in turn further eject tray  20  in the direction of arrow O, as shown in  FIG. 2E . Alternatively, in some embodiments, when the application of the user input force on user interface portion  52  is terminated, user interface portion  52  may be configured to remain in its second user interface state of  FIG. 2D  and tray interface portion  58  may remain in its second tray interface state of  FIG. 2D  (e.g., until tray  20  is re-inserted into device  10 ). 
     As shown in  FIG. 2A , before any portion of tray  20  has been inserted into housing  18 , such as when end  23  of tray  20  is positioned just outside opening  19 , user interface portion  52  may be configured to be in its first user interface state, such that tray interface portion  58  may be in its first tray interface state. In some embodiments (e.g., as described in greater detail with respect to  FIGS. 8A-8C ), tray  20  may not interact with tray interface portion  58  during the insertion of tray  20  into housing  18 , such that tray interface portion  58  may not change from its first tray interface state to its second tray interface state, and such that tray interface portion  58  may remain in its first tray interface state throughout the entire tray insertion process of  FIGS. 2A-2C . 
     Alternatively, in some other embodiments (e.g., as described in greater detail with respect to  FIGS. 3A-3C ), once tray  20  has been initially inserted through opening  19  and into housing  18  in the direction of arrow I to a certain extent, as shown in  FIG. 2B , for example, a portion of tray  20  may interact with a portion of tray interface portion  58  such that tray interface portion  58  may change from its first tray interface state to its second tray interface state. For example, in some embodiments, once tray  20  has been at least partially inserted in the direction of arrow I into housing  18 , an ejector interface portion  28  on bottom surface  25   b  of tray  20  may interact with tray interface portion  58  (e.g., ejector interface portion  28  may apply a tray input force on tray interface portion  58  in the direction of arrow I) such that tray interface portion  58  may change from its first tray interface state to its second tray interface state (e.g., as described in greater detail with respect to  FIG. 3B ). 
     Moreover, in such embodiments, once tray  20  has been further inserted through opening  19  and into housing  18  in the direction of arrow I to its fully loaded position, as shown in  FIG. 2C , for example, the application of such a tray input force by ejector interface portion  28  onto tray interface portion  58  may be terminated (e.g., tray interface portion  58  may overcome such a tray input force). When tray interface portion  58  overcomes such a tray input force, tray interface portion  58  may be configured to change from its second tray interface state back to its first tray interface state. This change from the second tray interface state to the first tray interface state may cause tray interface portion  58  to at least partially secure tray  20  to ejector mechanism  50  (e.g., to at least partially secure tray  20  in its functional or fully loaded position of  FIG. 2C ). For example, when tray  20  reaches its fully loaded position within housing  18 , such that the application of a tray input force by ejector interface portion  28  of tray  20  onto tray interface portion  58  may be terminated, and such that tray interface portion  58  may change from its second tray interface state back to its first tray interface state, tray interface portion  58  may interact with a securement feature of tray  20  for holding tray  20  in its fully loaded position (e.g., as described in greater detail with respect to  FIG. 3C ). 
     Therefore, tray interface portion  58  may either be in its first tray interface state or in its second tray interface state at the stage of the insertion of tray  20  into housing  18  of  FIG. 2B . Moreover, if tray  20  does interact with tray interface portion  58  during the stage of insertion of  FIG. 2B , such that tray interface portion  58  may change from its first tray interface state to its second tray interface state, such a state change of tray interface portion  58  may cause user interface portion  52  to change from its first user interface state to its second user interface state. While, in other embodiments, if tray  20  does not interact with tray interface portion  58  during the stage of insertion of  FIG. 2B , such that tray interface portion  58  may not change from its first tray interface state to its second tray interface state, then user interface portion  52  may not change from its first user interface state to its second user interface state. Therefore, user interface portion  52  may likewise be in its first user interface state or in its second user interface state at the stage of the insertion of tray  20  into housing  18  of  FIG. 2B . 
     The tendency for ejector mechanism  50  to change between its first and second ejector mechanism states (e.g., the tendency for user interface portion  52  and tray interface portion  58  to change between their respective first and second states), may be defined by one or more material characteristics of user interface portion  52  and/or tray interface portion  58 , by one or more characteristics of how end  51  and/or end  59  is fixed to device  10 , and/or by one or more characteristics of coupling  55 . For example, in some embodiments, the material characteristics of user interface portion  52  and the characteristics of how end  51  is fixed to device  10  may be such that, absent any external forces acting on user interface portion  52  (e.g., any user input force provided by user input tool  98  or any force provided by tray interface portion  58  via coupling  55 ), user interface portion  52  may not be biased to exist in one user interface state or the other. That is, if first user interface portion end  51  of a rigid user interface portion  52  is coupled to housing  18  using an unbiased free swinging hinge, such a user interface portion  52  may have no tendency to move from its second user interface state to its first user interface state or from its first user interface state to its second user interface state, absent being coupled via coupling  55  to a tray interface portion  58  having a tendency to move, respectively, from its second tray interface state to its first tray interface state or from its first tray interface state to its second tray interface state (see, e.g.,  FIG. 2B ). Similarly, in other embodiments, the material characteristics of tray interface portion  58  and the characteristics of how end  59  is fixed to device  10  may be such that, absent any external forces acting on tray interface portion  58  (e.g., any tray input force provided by tray  20  or any force provided by user interface portion  52  via coupling  55 ), tray interface portion  58  may not be biased to exist in one tray interface state or the other. That is, if second tray interface portion end  59  of a rigid tray interface portion  58  is coupled to housing  18  using an unbiased free swinging hinge, such a tray interface portion  58  may have no tendency to move from its second tray interface state to its first tray interface state or from its first tray interface state to its second tray interface state, absent being coupled via coupling  55  to a user interface portion  52  having a tendency to move, respectively, from its second user interface state to its first user interface state or from its first user interface state to its second user interface state. In yet other embodiments, user interface portion  52  and tray interface portion  58  may each be independently biased to exist in one of their two respective states, such that, when they are coupled via coupling  55 , the tendency of ejector mechanism  50  to move either from its second ejector mechanism state to its first ejector mechanism state or from its first ejector mechanism state to its second ejector mechanism state may be based on the combination of the independent tendencies of user interface portion  52  and tray interface portion  58  to do so. Any suitable tension may exist between ends  51  and  59  to bias user interface portion  52  and/or tray interface portion  58  such that ejector mechanism  50  may remain in a particular ejector mechanism state when an input force (e.g., a user input force and/or a tray input force) is not applied to ejector mechanism  50 . For example, in some embodiments, when ejector mechanism  50  is in its first ejector mechanism state, at least one of user interface portion  52  and tray interface portion  58  may be relaxed in its first state, and when ejector mechanism  50  is in its second ejector mechanism state, at least one of user interface portion  52  and tray interface portion  58  may be pulled taut in its second state. By changing from a state of tautness to a state of relaxation (e.g., from a taut state having a first stress to a relaxed state having a second stress that may be lower than the first stress), tray interface portion  58  may impart an ejection force onto tray  20 . As another example, in some embodiments, when ejector mechanism  50  is in its first ejector mechanism state, at least one of user interface portion  52  and tray interface portion  58  may be held taut in its first state, and when ejector mechanism  50  is in its second ejector mechanism state, at least one of user interface portion  52  and tray interface portion  58  may be relaxed in its second state. By changing from a state of relaxation to a state of tautness (e.g., from a relaxed state having a first stress to a taut state having a second stress that may be greater than the first stress), tray interface portion  58  may impart an ejection force onto tray  20 . 
     In some embodiments, first end  51  of user interface portion  52  may be the only portion of user interface portion  52  that is coupled to any portion of housing  18 , connector  40 , or any other portion of device  10  other than tray interface portion  58 . Similarly, in some embodiments, second end  59  of tray interface portion  58  may be the only portion of tray interface portion  58  that is coupled to any portion of housing  18 , connector  40 , or any other portion of device  10  other than user interface portion  52 . That is, besides ends  51  and  59 , which may be distinct with tension therebetween, no other portion of ejector mechanism  50  may be coupled to any other portion of device  10 . Coupling  55  and ends  53  and  57  may be free from any other components of device  10  and may only be impacted by a removable entity or a user input tool. 
     Such that a user of device  10  may eject tray  20  from connector  40  using ejector mechanism  50  (e.g., when tray  20  is held in its functional or fully loaded position by connector  40 , as shown in  FIG. 2C , for example), at least a portion of user interface portion  52  may be accessible to a user through user interface opening  17 . As mentioned, user interface opening  17  may be an opening provided through any suitable portion of housing  18  for providing a user external to housing  18  with the ability to apply a user input force in the direction of arrow UI onto user interface portion  52 . For example, as shown in  FIGS. 2A-2E , user interface opening  17  may be provided through bottom wall  18   b  of housing  18 . It is to be noted that, although user interface opening  17  is shown in  FIGS. 2A-2E  to be provided through bottom wall  18   b , which may be the same housing wall through which module housing opening  19  may be provided, user interface opening  17  may be provided through any other wall of housing  18  having any geometrical or spatial relationship with the wall of housing  18  through which module housing opening  19  may be provided. For example, in other embodiments, user interface opening  17  may be provided through any one of top wall  18   t , front wall  18   f , back wall  18   k , left wall  18   l , and right wall  18   r  when module housing opening  19  is provided through bottom wall  18   b , and at least a portion of user interface portion  52  may be accordingly positioned within housing  18  to receive a user input force through user interface opening  17 . Moreover, although a user input force may be shown in  FIGS. 2A-2E  to be applied in the direction of arrow UI that may be parallel to the direction of arrow I along which tray  20  may be inserted through module housing opening  19 , the direction of arrow UI of a user input force applied to user input portion  52  of ejector mechanism  50  may have any suitable directional relationship with respect to the direction of arrow I (e.g., the directions of arrows UI and I may be opposite, perpendicular, skew, etc.). 
     As described in greater detail with respect to the various embodiments of  FIGS. 3A-7B , when user interface portion  52  is in its first user interface state, at least a portion of user interface portion  52  may be configured to cover at least a portion of user interface opening  17 . In some embodiments, when user interface portion  52  is in its first user interface state, a portion of user interface portion  52  may be biased to press against a portion of housing  18  about user interface opening  17  (e.g., against inner surface  18   i  of housing  18  about opening  17 ) and/or may be biased to fit into user interface opening  17  (e.g., within opening  17 , between inner surface  18   i  and outer surface  18   o  of housing  18 ), such that user interface portion  52  in its first user interface state may provide an environmental seal for preventing ingress of water or other debris into housing  18  through user interface opening  17 . However, in some embodiments, user interface opening  17  may not be an opening that may even permit water or other debris from traveling completely therethrough. Instead, in some embodiments, user interface opening  17  may include a cover that may allow a user input force to be applied to one side of the cover, and then transferred to the other side of the cover, and then onto user interface portion  52 , while at the same time preventing debris from passing through such a cover. For example, as shown in  FIG. 2E , a cover  17 ′ may be positioned across and/or within user interface opening  17  and may be an elastic filter that can flex when a user input force is applied thereto and that can prevent certain fluids from passing therethrough (e.g., water, dirt, or other debris that could jeopardize the performance of device  10 ). 
     In some embodiments, as shown in  FIGS. 3A-7B , for example, ejectable component assembly  16  may include an ejector mechanism  150 , which may be similar to ejector mechanism  50  of  FIGS. 2A-2E , for at least partially ejecting tray  20  and/or module  30  from connector  40  and/or housing  18 . Ejector mechanism  150  may include a user interface portion  152  and a tray interface portion  158 . User interface portion  152  may extend between a first user interface portion end  151  and a second user interface portion end  153 . Tray interface portion  158  may extend between a first tray interface portion end  157  and a second tray interface portion end  159 . First end  151  of user interface portion  152  may be coupled to a fixed portion of device  10  (e.g., first end  151  may be coupled to a portion of housing  18  or another component of device  10  whose position may be fixed with respect to housing  18 ) and second end  159  of tray interface portion  158  may be coupled to another fixed portion of device  10  (e.g., second end  159  may be coupled to a portion of housing  18  or another component of device  10  whose position may be fixed with respect to housing  18 ), while second end  153  of user interface portion  152  may be coupled to first end  157  of tray interface portion  158 . 
     As described above with respect to user interface portion  52  of ejector mechanism  50  of  FIGS. 2A-2E , user interface portion  152  of ejector mechanism  150  may be any suitable unitary component or collection of suitable components that may be capable deflecting, deforming, bending, springing, pivoting, translating, rotating, moving, or otherwise changing between a first user interface state or position (e.g., as shown in  FIGS. 3A ,  3 C,  3 E,  4 A,  4 C,  4 E,  5 A,  5 C,  5 E,  6 , and  7 A) and a second user interface state or position (e.g., as shown in  FIGS. 3B ,  3 D,  4 B,  4 D,  5 B,  5 D, and  7 B). User interface portion  152  may be made of any suitable material, such as rubber, plastic, metal, or any suitable combinations thereof. In some embodiments, user interface portion  152  may be a single component made of any suitable material while, in other embodiments, user interface portion  152  may be several distinct components. Different portions of user interface portion  152  may be flexible or rigid. For example, a first portion of user interface portion  152  at or near first end  151  may be rigid (e.g., for coupling to a portion of housing  18 ), while another portion of user interface portion  152  may be flexible (e.g., for bending or deflecting from the first user interface state to the second user interface state). 
     Moreover, as described above with respect to tray interface portion  58  of ejector mechanism  50  of  FIGS. 2A-2E , tray interface portion  158  of ejector mechanism  150  may be any suitable unitary component or collection of suitable components that may be capable of deflecting, deforming, bending, springing, pivoting, translating, rotating, moving, or otherwise changing between a first tray interface state or position (e.g., as shown in  FIGS. 3A ,  3 C,  3 E,  4 A,  4 C,  4 E,  5 A,  5 C,  5 E,  6 , and  7 A) and a second tray interface state or position (e.g., as shown in  FIGS. 3B ,  3 D,  4 B,  4 D,  5 B,  5 D, and  7 B). Tray interface portion  158  may be made of any suitable material, such as rubber, plastic, metal, or any suitable combinations thereof. In some embodiments, tray interface portion  158  may be a single component made of any suitable material while, in other embodiments, tray interface portion  158  may be several distinct components. Different portions of tray interface portion  158  may be flexible or rigid. For example, a first portion of tray interface portion  158  at or near second end  159  may be rigid (e.g., for coupling to a portion of housing  18 ), while another portion of tray interface portion  158  may be flexible (e.g., for bending or deflecting from the first tray interface state to the second tray interface state). 
     For example, as shown in  FIGS. 3A-7B , user interface portion  152  may include one or more plates (e.g., plate  172  and/or plate  182 ) that may extend between first user interface portion end  151  and second user interface portion end  153 , and first end  151  may be fixed or otherwise coupled to inner surface  18   i  of wall  18   b  by one or more suitable mountings  161  (e.g., one or more welding or bonding locations, cladding, insert molding, screws, fasteners, rivets, hooks, tabs, holes, etc.). When user interface portion  152  is in its first user interface state (e.g., as shown in  FIGS. 3A ,  3 C,  3 D,  4 A,  4 C,  4 D,  5 A,  5 C,  5 D,  6 , and  7 A), user interface portion  152  may extend against and along inner surface  18   i  of wall  18   b  from first end  151  towards second end  153 . In this first user interface state, user interface portion  152  may extend across and block at least a portion of user interface opening  17  provided through inner surface  18   i , such that user interface portion  152  may be configured to press against housing  18  about user interface opening  17  for preventing debris from entering into housing  18  through user interface opening  17  when user interface portion  152  is in its first user interface state. 
     Moreover, as shown in  FIGS. 3A-7B , tray interface portion  158  may include a beam (e.g., beam  192 ) that may extend between first tray interface portion end  157  and second tray interface portion end  159 , and second end  159  may be fixed or otherwise coupled to inner surface  18   i  of wall  18   k  by one or more suitable mountings  169  (e.g., a ball and socket mounting, a hinge pin mounting, a compliant coupler mounting, etc.). When tray interface portion  158  is in its first tray interface state (e.g., as shown in  FIGS. 3A ,  3 C,  3 D,  4 A,  4 C,  4 D,  5 A,  5 C,  5 D,  6 , and  7 A), tray interface portion  158  may extend across at least a portion of module housing opening  19  from second end  159  towards first end  157 . In this first tray interface state, tray interface portion  158  may extend across at least a portion of module housing opening  19 , such that tray interface portion  158  may interact with at least a portion of tray  20  when tray  20  is inserted through module housing opening  19  and into connector  40 . 
     In some embodiments, first end  151  of user interface portion  152  and second end  159  of tray interface portion  158  may be fixed with respect to one another or be at least partially constrained with respect to one another. Each one of first end  151  and second end  159  may be fixed to or have its movement at least partially constrained by any portion of device  10  (e.g., housing  18 , connector  40 , etc.). First end  151  may be fixed to or have its movement at least partially constrained/restrained by a first portion of device  10  at a first location within housing  18  by mounting  161  and second end  159  may be fixed to or otherwise have its movement at least partially constrained/restrained by a second portion of device  10  at a second location within housing  18  by mounting  169 . 
     First end  157  of tray interface portion  158  may be coupled to second end  153  of user interface portion  152  in any suitable manner using any suitable coupling  155 . Coupling  155  may allow constrained relative motion between user interface portion  152  and tray interface portion  158 , such that user interface portion  152  may change between its first and second user interface states when tray interface portion  158  may change between its first and second tray interface states, and vice versa. Therefore, coupling  155  may allow for ejector mechanism  150  to change between a first ejector mechanism state (e.g., when each one of user interface portion  152  and tray interface portion  158  is in its respective first state) and a second ejector mechanism state (e.g., when each one of user interface portion  152  and tray interface portion  158  is in its respective second state). For example, as shown in  FIGS. 3A-7B , coupling  155  formed between second end  153  of user interface portion  152  and first end  157  of tray interface portion  158  may be a hinge bearing, such that first end  157  and second end  153  may each relatively rotate about an axis A of coupling  155  (see, e.g., axis A of  FIGS. 3A ,  4 A, and  6 ). In other embodiments, coupling  155  may be a ball and socket, a hinge pin, a compliant coupler, or any other suitable mechanism for coupling first end  157  of tray interface portion  158  to second end  153  of user interface portion  152 . 
     The tendency for ejector mechanism  150  to change between its first and second ejector mechanism states (e.g., the tendency for user interface portion  152  and tray interface portion  158  to change between their respective first and second states), may be defined by one or more material characteristics of user interface portion  152  and/or tray interface portion  158 , by one or more characteristics of mounting  161  and/or mounting  169 , and/or by one or more characteristics of coupling  155 . For example, in some embodiments, the material characteristics of user interface portion  152  and the characteristics of mounting  161  may be such that, absent any external forces acting on user interface portion  152  (e.g., any user input force provided by user input tool  98  or any force provided by tray interface portion  158  via coupling  155 ), user interface portion  152  may not be biased to exist in one user interface state or the other. That is, if first user interface portion end  151  of a rigid user interface portion  152  is coupled to housing  18  using an unbiased free swinging hinge mounting  161 , such a user interface portion  152  may have no tendency to move in either the direction of arrow U 1  from its second user interface state to its first user interface state or in the direction of arrow U 2  from its first user interface state to its second user interface state, absent being coupled via coupling  155  to a tray interface portion  158  having a tendency to move, respectively, in either the direction of arrow T 1  from its second tray interface state to its first tray interface state or in the direction of arrow T 2  from its first tray interface state to its second tray interface state (see, e.g.,  FIGS. 3B and 7B ). Similarly, in other embodiments, the material characteristics of tray interface portion  158  and the characteristics of mounting  169  may be such that, absent any external forces acting on tray interface portion  158  (e.g., any tray input force provided by tray  20  or any force provided by user interface portion  152  via coupling  155 ), tray interface portion  158  may not be biased to exist in one tray interface state or the other. That is, if second tray interface portion end  159  of a rigid tray interface portion  158  is coupled to housing  18  using an unbiased free swinging hinge mounting  169 , such a tray interface portion  158  may have no tendency to move in either the direction of arrow T 1  from its second tray interface state to its first tray interface state or in the direction of arrow T 2  from its first tray interface state to its second tray interface state, absent being coupled via coupling  155  to a user interface portion  152  having a tendency to move, respectively, in either the direction of arrow U 1  from its second user interface state to its first user interface state or in the direction of arrow U 2  from its first user interface state to its second user interface state. In yet other embodiments, user interface portion  152  and tray interface portion  158  may each be independently biased to exist in one of their two respective states, such that, when they are coupled via coupling  155 , the tendency of ejector mechanism  150  to move in either the direction of arrow E 1  from its second ejector mechanism state to its first ejector mechanism state or in the direction of arrow E 2  from its first ejector mechanism state to its second ejector mechanism state may be based on the combination of the independent tendencies of user interface portion  152  and tray interface portion  158  to do so. Any suitable tension may exist between mountings  161  and  169  to bias user interface portion  152  and/or tray interface portion  158  such that ejector mechanism  150  may remain in a particular ejector mechanism state when an input force (e.g., a user input force and/or a tray input force) is not applied to ejector mechanism  150 . For example, in some embodiments, when ejector mechanism  150  is in its first ejector mechanism state, at least one of user interface portion  152  and tray interface portion  158  may be relaxed in its first state, and when ejector mechanism  150  is in its second ejector mechanism state, at least one of user interface portion  152  and tray interface portion  158  may be pulled taut in its second state. By changing from a state of tautness to a state of relaxation (e.g., from a taut state having a first stress to a relaxed state having a second stress that may be lower than the first stress), tray interface portion  158  may impart an ejection force onto tray  20 . As another example, in some embodiments, when ejector mechanism  150  is in its first ejector mechanism state, at least one of user interface portion  152  and tray interface portion  158  may be held taut in its first state, and when ejector mechanism  150  is in its second ejector mechanism state, at least one of user interface portion  152  and tray interface portion  158  may be relaxed in its second state. By changing from a state of relaxation to a state of tautness (e.g., from a relaxed state having a first stress to a taut state having a second stress that may be greater than the first stress), tray interface portion  158  may impart an ejection force onto tray  20 . 
     For example, as shown in  FIGS. 3A ,  4 A,  5 A, and  7 A, before any portion of tray  20  has been inserted into housing  18 , before any user input force has been applied to user interface portion  152 , and before any tray input force has been applied to tray interface portion  158 , ejector mechanism  150  may be configured to be in its first ejector mechanism state. Therefore, as shown, when ejector mechanism  150  is in its first ejector mechanism state, user interface portion  152  may extend along inner surface  18   i  and across at least a portion of user interface opening  17 , and tray interface portion  158  may extend across at least a portion of module housing opening  19 . In this first ejector mechanism state, ejector mechanism  150  may be biased such that user interface portion  152  may exert a force in the direction of arrow U 1  on housing  18  or on any other suitable portion of device  10 , and/or such that tray interface portion  158  may exert a force in the direction of arrow T 1  on housing  18  or on any other suitable portion of device  10 . In other embodiments, neither user interface portion  152  nor tray interface portion  158  may be exerting any force in the directions of respective arrows U 1  and T 1  when ejector mechanism  150  is in its first ejector mechanism state. 
     Once tray  20  has been initially inserted through opening  19  and into housing  18  in the direction of arrow I to a certain extent, as shown in  FIGS. 3B ,  4 B, and  5 B, for example, a portion of tray  20  may interact with a portion of tray interface portion  158  such that tray interface portion  158  may change from its first tray interface state to its second tray interface state. For example, in some embodiments, once tray  20  has been at least partially inserted in the direction of arrow I into housing  18 , ejector interface portion  28  on bottom surface  25   b  of tray  20  may interact with tray interface portion  158  (e.g., ejector interface portion  28  may apply a tray input force on tray interface portion  158  in the direction of arrow I) such that tray interface portion  158  may change from its first tray interface state to its second tray interface state. As shown, a leading edge  29  of ejector interface portion  28  may initially contact tray interface portion  158  and may apply a tray input force onto tray interface portion  158  in the direction of arrow I as tray  20  is initially inserted into device  10  in the direction of arrow I. 
     When this tray input force is applied by tray  20  onto tray interface portion  158  in the direction of arrow I, ejector mechanism  150  may be configured to change from its first ejector mechanism state to its second ejector mechanism state (e.g., tray interface portion  158  may be configured to change from its first tray interface state to its second tray interface state and user interface portion  152  may be configured to change from its first user interface state to its second user interface state). For example, in some embodiments, as tray  20  may be inserted further into device  10 , and as tray  20  may further apply the tray input force onto tray interface portion  158  in the direction of arrow I, tray interface portion  158  may change from its first tray interface state to its second tray interface state. As tray interface portion  158  and, thus, ejector mechanism  150  change from their first states to their second states, ejector mechanism  150  may be biased or otherwise configured to exert a force in the direction of arrow E 1  onto tray  20  (e.g., tray interface portion  158  may be biased or otherwise configured to exert a force in the direction of arrow T 1  onto tray  20 ). At some point, during the further insertion of tray  20  into device  10  (e.g., from  FIG. 3B  to  FIG. 3C  in the direction of arrow I), the force exerted by ejector mechanism  150  onto tray  20  in the direction of arrow E 1 /T 1  may overcome the further tray input force exerted by tray  20  onto ejector mechanism  150  in the direction of arrow I. At that point, ejector mechanism  150  may be configured to return from its second ejector mechanism state of  FIGS. 3B ,  4 B, and  5 B to its first ejector mechanism state of  FIGS. 3C ,  4 C, and  5 C. For example, as shown, leading edge  29  of ejector interface portion  28  may be angled such that the competing forces being exerted by tray  20  and tray interface portion  158  may cause tray interface portion  158  to slide downwardly along leading edge  29  and to enter into a securement feature  27  of ejector interface portion  28 . As shown in  FIGS. 3C ,  4 C, and  5 C, for example, device  10  may be configured such that, when tray interface portion  158  does enter into securement feature  27  of ejector interface portion  28 , tray  20  may be in its fully loaded position. In such embodiments, the interaction of securement feature  27  with tray interface portion  158  in its first state may retain tray  20  in its fully loaded position (e.g., without requiring retention members  42   a  and  42   b  to retain tray  20  at that fully loaded position). Therefore, in some embodiments, tray interface portion  158  may interact with tray  20  to prevent tray  20  from sliding out of device  10  once tray  20  is held in its fully loaded position by tray interface portion  158 . In some embodiments, the geometry of ejector interface portion  28  and the relative geometry of tray interface portion  158  may be configured such that tray interface portion  158  may snap into or otherwise be securely retained within securement feature  27 . This retention may be an active contact between tray  20  and tray interface portion  158  (e.g., contact that may reinforce itself via interlocking geometry). In other embodiments, such retention of or contact between tray interface portion  158  and ejector interface portion  28  may be maintained by an active contact that may reinforce itself via attraction (e.g., magnetic attraction) rather than via geometry. For example, as described with respect to an embodiment of  FIG. 8C , attractable magnets or any other suitable mechanisms may be provided to hold tray interface portion  158  and ejector interface portion  28  together. In such active contact embodiments, tray interface portion  158  may be configured to hold tray  20  in its fully loaded position (e.g., without the aid of retention members  42   a  and  42   b ). In yet other embodiments, one or more magnets could be provided to aid alignment and/or engagement of securement feature  27  with tray interface portion  158 . 
     When retained in its fully loaded position of  FIGS. 3C ,  4 C, and  5 C, outer surface  21   x  of outer tray end  21  of tray  20  may be substantially flush and/or continuous with an outer surface  18   o  of housing  18  about opening  19 . In some embodiments, ejector mechanism  150  may be biased to remain in its first ejector mechanism state, such that ejector mechanism  150  may prevent tray  20  from being inserted further in the direction of arrow I. Additionally or alternatively, a portion of housing  18  may interact with tray  20  to prevent tray  20  from being inserted further in the direction of arrow I. For example, as shown in  FIG. 4C , housing  18  may include a housing key portion  18   y  that may be positioned within or adjacent an end of opening  19 , such that housing key portion  18   y  may obstruct and prevent a portion of tray  20  (e.g., a portion of outer tray end  21 ) from being inserted further in the direction of arrow I. Ejector mechanism  150  may be configured such that housing key portion  18   y  may interact with tray  20  at about the same moment that tray interface portion  158  may snap into or otherwise be securely retained within securement feature  27 . Moreover, housing key portion  18   y  may be positioned with respect to opening  19  such that tray  20  may not be inserted too far within opening  19  while tray  20  is upside down. For example, if tray  20  were attempted to be inserted into opening  19  in the direction of arrow I while bottom surface  25   b  of tray  20  was facing upwards (e.g., towards housing key portion  18   y  of  FIG. 4B ), then housing key portion  18   y  may be configured to obstruct and prevent ejector interface portion  28  from being inserted in the direction of arrow I beyond housing key portion  18   y . Therefore, a user may be prevented from inserting tray  20  too far into opening  18  when tray  20  is upside down. 
     Once tray  20  is held in this functional or fully loaded position within housing  18 , ejector mechanism  150  may be configured to receive a user input force, which may cause ejector mechanism  150  to change from its first ejector mechanism state to its second ejector mechanism state, which may at least partially eject tray  20  from device  10 . For example, as shown in  FIGS. 3D ,  4 D,  5 D, and  7 B, first end  99  of user input tool  98  may be inserted through user interface opening  17  in housing  18  for applying a user input force in the direction of arrow UI onto a portion of user interface portion  152 . When this user input force is applied onto user interface portion  152 , user interface portion  152  may be configured to change from its first user interface state of  FIGS. 3C ,  4 C, and  5 C to its second user interface state of  FIGS. 3D ,  4 D,  5 D, and  7 B. When user interface portion  152  changes from its first user interface state to its second user interface state, the change may cause tray interface portion  158  to change from its first tray interface state of  FIGS. 3C ,  4 C, and  5 C to its second tray interface state of  FIGS. 3D ,  4 D,  5 D, and  7 B. This alteration of states by tray interface portion  158  may cause at least a portion of tray interface portion  158  to interact with tray  20  for at least partially ejecting tray  20  from device  10  in the direction of arrow O, as shown in  FIGS. 3D ,  4 D,  5 D, and  7 B. 
     For example, as shown, when tray interface portion  158  changes from its first tray interface state to its second tray interface state for at least partially ejecting tray  20 , securement feature  27  of ejector interface portion  28  may be shaped such that the competing forces being exerted by tray  20  and tray interface portion  158  may cause tray interface portion  158  to slide out from securement feature  27  and upwardly along leading edge  29 . In some embodiments, such sliding of tray interface portion  158  along leading edge  29  of tray  20  may force tray  20  at least partially in the direction of arrow O. As shown in  FIGS. 3D ,  4 D, and  5 D, for example, device  10  may be configured such that, when tray interface portion  158  does exit securement feature  27  of ejector interface portion  28 , ejector mechanism  150  may no longer retain tray  20  in its fully loaded position. Then, once tray interface portion  158  is in its second tray interface state of  FIGS. 3D ,  4 D, and  5 D, and once the application of the user input force on user interface portion  152  is terminated, ejector mechanism  150  may be configured to return from its second ejector mechanism state to its first ejector mechanism state. For example, when first end  99  of user input tool  98  is at least partially withdrawn through user interface opening  17  in the direction of arrow UO for terminating the application of a user input force on a portion of user interface portion  152 , user interface portion  152  may be configured to return from its second user interface state of  FIGS. 3D ,  4 D, and  5 D to its first user interface state of  FIGS. 3E ,  4 E, and  5 E. This change of user interface portion  152  from its second user interface state to its first user interface state may cause tray interface portion  158  to change from its second tray interface state of  FIGS. 3D ,  4 D, and  5 D to its first tray interface state of  FIGS. 3E ,  4 E, and  5 E, which may in turn eject (e.g., further eject) tray  20  in the direction of arrow O from device  10 . For example, the force that tray interface portion  158  may be biased or otherwise configured to exert on tray  20  in the direction of arrow T 1  when tray interface portion  158  changes from its second tray interface state to its first tray interface state may be great enough to overcome any retention force that may be applied to tray  20  (e.g., by retention members  42   a  and  42   b  of connector  40  on tray  20  in the direction of arrows Ba and Bb), such that tray  20  may be at least partially ejected from connector  40  in the direction of arrow O (e.g., from the tray position of  FIGS. 3D ,  4 D, and  5 D to the at least partially ejected tray position of  FIGS. 3E ,  4 E, and  5 E). In some embodiments, tray interface portion  158  may be configured to exert an ejection force in the direction of arrow T 1  onto leading edge  29  of ejector interface portion  28  of tray  20  or onto any other suitable portion of tray  20  in order to at least partially eject tray  20  from device  10 . 
     Therefore, ejector mechanism  150  of  FIGS. 3A-7B  may be configured to change between a first ejector mechanism state (e.g., an ejector mechanism state that may include a first user interface state and a first tray interface state) and a second ejector mechanism state (e.g., an ejector mechanism state that may include a second user interface state and a second tray interface state), such that ejector mechanism  150  may receive, retain, and/or eject tray  20  and/or removable module  30 . For example, user interface portion  152  may be configured to change from the first user interface state to the second user interface state when a user input force is applied by a user onto user interface portion  152  (e.g., as shown in  FIGS. 3D ,  4 D,  5 D, and  7 B) or in response to tray interface portion  158  changing from the first tray interface state to the second tray interface state (e.g., as shown in  FIGS. 3B ,  4 B, and  5 B). User interface portion  152  may also be configured to change from the second user interface state to the first user interface state when the application of a user input force onto user interface portion  152  is terminated (e.g., as shown in  FIGS. 3E ,  4 E, and  5 E) or in response to tray interface portion  158  changing from the second tray interface state to the first tray interface state (e.g., as shown in  FIGS. 3C ,  4 C, and  5 C). Moreover, tray interface portion  158  may be configured to change from the first tray interface state to the second tray interface state when a tray input force is applied by tray  20  onto tray interface portion  158  (e.g., as shown in  FIGS. 3B ,  4 B, and  5 B) or in response to user interface portion  152  changing from the first user interface state to the second user interface state (e.g., as shown in  FIGS. 3D ,  4 D,  5 D, and  7 B). Tray interface portion  158  may also be configured to change from the second tray interface state to the first tray interface state when the application of a tray input force onto tray interface portion  158  is terminated or overcome (e.g., as shown in  FIGS. 3C ,  4 C, and  5 C) or in response to user interface portion  152  changing from the second user interface state to the first user interface state (e.g., as shown in  FIGS. 3E ,  4 E, and  5 E). 
     In some embodiments, in response to user interface portion  152  receiving a user input force and thereby changing from the first user interface state to the second user interface state, the resultant change of tray interface portion  158  from the first tray interface state to the second tray interface state may cause tray interface portion  158  to at least partially eject tray  20  from connector  40  and/or opening  19  (e.g., as shown in  FIGS. 3D ,  4 D,  5 D, and  7 B). Moreover, in response to the termination of the application of a tray input force onto tray interface portion  158  (e.g., when tray interface portion  158  may overcome a tray input force), the resultant change of tray interface portion  158  from the second tray interface state to the first tray interface state may cause tray interface portion  158  to at least partially secure tray  20  to ejector mechanism  150  (e.g., to at least partially secure tray  20  in its functional or fully loaded position of  FIGS. 3C ,  4 C, and  5 C). 
     As shown in  FIGS. 3A-7B , for example, user interface portion  152  may include a first user interface plate  172  that may extend between a first end  171  and a second end  173 . First end  171  of first user interface plate  172  may be fixed or otherwise coupled to housing  18  by at least one mounting component  161  (e.g., at least one weld or other suitable bonding element). For example, as shown, first end  171  of first user interface plate  172  may be fixed or otherwise coupled to inner surface  18   i  of wall  18   b , such that, when user interface portion  152  is in its first user interface state (e.g., as shown in  FIGS. 3A ,  3 C,  3 E,  4 A,  4 C,  4 E,  5 A,  5 C,  5 E, and  7 A), first user interface plate  172  may extend against and along inner surface  18   i  of wall  18   b  towards second end  173 . In this first user interface state, first user interface plate  172  may extend across and block at least a portion of user interface opening  17  provided through inner surface  18   i , such that user interface portion  152  may be configured to press against housing  18  about user interface opening  17  for preventing debris from entering into housing  18  through user interface opening  17  when user interface portion  152  is in its first user interface state. In some embodiments, user interface portion  152  may only include first user interface plate  172 , and coupling  155  may couple second end  173  of first user interface plate  172  to first end  157  of tray interface portion  158  (not shown). 
     As shown, user interface portion  152  may alternatively or additionally include a second user interface plate  182  that may extend between a first end  181  and a second end  183 . In some embodiments, user interface portion  152  may only include second user interface plate  182  and not first user interface plate  172 , and coupling  155  may couple second end  183  of second user interface plate  182  to first end  157  of tray interface portion  158 . In other embodiments, user interface portion  152  may include both first user interface plate  172  and second user interface plate  182 , as shown in  FIGS. 3A-7B . Along the lengths of plates  172  and  182 , plates  172  and  182  may transverse each other, such that, for example, the relative positions of plates  172  and  182  (e.g., with respect to housing wall  18   b ) may be different at first ends  171 / 181  than at second ends  173 / 183 . For example, as shown, plates  172  and  182  may be provided in an offset stack such that first end  181  of second plate  182  may be positioned between housing wall  18   b  and first end  171  of first plate  172 , while second end  173  of first plate  172  may be positioned between housing wall  18   b  and second end  183  of second plate  182 . As shown in  FIG. 6 , for example, first plate  172  may pass through an opening  185  in second plate  182 . When first ends  171  and  181  are independently or together coupled to housing  18  by one or more mounting components  161 , portions of plates  172  and  182  may slide and/or pivot with respect to one another (e.g., as shear plates or a slip seam) when a user input force is applied to user interface portion  152  (e.g., when first end  99  of user input tool  98  applies a user input force in the direction of arrow UI onto a portion of first plate  172 , as shown in  FIGS. 3D ,  4 D,  5 D, and  7 B). 
     As shown in  FIGS. 7A and 7B , for example, when user interface portion  152  includes first plate  172  and second plate  182  configured in a dual plate offset stack, first plate  172  may pivot about a first pivot point P 1  and second plate  182  may pivot about a second pivot point P 2  as user interface portion  152  changes between its first and second user interface states. Accordingly, these different pivot points may allow second end  173  of first plate  172  and second end  183  of second plate  182  to travel by different amounts when changing between user interface states. For example, as shown, second end  173  of first plate  172  may translate a first distance TP 1  when user interface portion  152  changes from its first user interface state to its second user interface state, whereas second end  183  of second plate  182  may translate a second distance TP 2  when user interface portion  152  changes from its first user interface state to its second user interface state. When user interface portion  152  includes first plate  172  and second plate  182  configured in a dual plate offset stack, second distance TP 2  may be greater than distance TP 1 , such that first end  157  of tray interface portion  158  may travel a significant distance along with second end  183  of second plate  182 , which may provide for a significant physical distinction between first and second tray interface states, while second end  173  of first plate  172  may travel a shorter distance, which may reduce the amount of galling or other degradation that first end  99  of user input tool  98  may inflict on a cosmetic surface portion  179  of first plate  172  proximate to second end  173  (e.g., a cosmetic surface portion of user interface portion  152  that may be visible to a user of device  10  through opening  17 ). Therefore, as shown, second end  173  of first plate  172  may be a free end that may not be directly coupled to any other component, while second end  183  of second plate  182  may be coupled to first end  157  of tray interface portion  158  via coupling  155 . By including both of plates  172  and  182 , rather than only a single one of plates  172  and  182 , user interface portion  152  may require less travel of user input tool  98  through opening  17  in the direction of arrow UI to activate the change of states of tray interface portion  158 . Offset pivot points of a multi-layer or multi-plate user interface portion may translate portions of ejector mechanism  150  with a user input force sooner than a single-layer or single-plate user interface portion. 
     As mentioned, the tendency for ejector mechanism  150  to change between its first and second ejector mechanism states (e.g., the tendency for user interface portion  152  and tray interface portion  158  to change between their respective first and second states), may be defined by one or more material characteristics of user interface portion  152  and/or tray interface portion  158 , by one or more characteristics of mounting  161  and/or mounting  169 , and/or by one or more characteristics of coupling  155 . For example, in some embodiments, the characteristics of mounting  161  and the characteristics of first plate  172  and/or second plate  182  may be such that user interface portion  152  may be biased to remain in the first user interface state absent any external forces acting on user interface portion  152  (e.g., any user input force provided by user input tool  98  or any force provided by tray interface portion  158  via coupling  155 ). For example, first plate  172  and/or second plate  182  may be a spring plate that may be biased to pivot about point P 1  and/or P 2  in the direction of arrow U 1  towards inner surface  18   i  of housing  18 . Such a spring bias may also force beam  192  in the direction of arrow T 1 , such that ejector mechanism  150  may tend to be in its first ejector mechanism state. Alternatively, in some embodiments, the characteristics of mounting  169  and the characteristics of beam  192  may be such that tray interface portion  158  may be biased to remain in the first tray interface state absent any external forces acting on tray interface portion  158  (e.g., any tray input force provided by tray  20  or any force provided by user interface portion  152  via coupling  155 ). For example, beam  192  may be a spring beam that may be biased to pivot about mounting  169  in the direction of arrow T 1  towards inner surface  18   i  of housing  18 . Such a spring bias may also force plate  172  and/or plate  182  in the direction of arrow U 1 , such that ejector mechanism  150  may tend to be in its first ejector mechanism state. In yet other embodiments, beam  192  and plates  172 / 182  may each be independently biased to exist in one of their two respective states, such that, when they are coupled via coupling  155 , the tendency of ejector mechanism  150  to move in either the direction of arrow E 1  from its second ejector mechanism state to its first ejector mechanism state or in the direction of arrow E 2  from its first ejector mechanism state to its second ejector mechanism state may be based on the combination of the independent tendencies of beam  192  and plates  172 / 182  to do so. Any suitable tension may exist between mountings  161  and  169  to bias user interface portion  152  and/or tray interface portion  158  such that ejector mechanism  150  may remain in a particular ejector mechanism state when an input force (e.g., a user input force and/or a tray input force) is not applied to ejector mechanism  150 . 
     In some embodiments, first end  151  of user interface portion  152  may be the only portion of user interface portion  152  that is coupled to any portion of housing  18 , connector  40 , or any other portion of device  10  other than tray interface portion  158 . Similarly, in some embodiments, second end  159  of tray interface portion  158  may be the only portion of tray interface portion  158  that is coupled to any portion of housing  18 , connector  40 , or any other portion of device  10  other than user interface portion  152 . That is, besides ends  151  and  159 , which may be distinct with tension therebetween, no other portion of ejector mechanism  150  may be coupled to any other portion of device  10 . Coupling  155  and ends  153  and  157  may be free from any other components of device  10  and may only be impacted by a removable entity or a user input tool. 
     In some embodiments, as shown in  FIGS. 8A-11 , for example, ejectable component assembly  16  may include an ejector mechanism  250 , which may be similar to ejector mechanism  50  of  FIGS. 2A-2E , for at least partially ejecting tray  20  and/or module  30  from connector  40  and/or housing  18 . Ejector mechanism  250  may include a user interface portion  252  and a tray interface portion  258 . User interface portion  252  may extend between a first user interface portion end  251  and a second user interface portion end  253 . Tray interface portion  258  may extend between a first tray interface portion end  257  and a second tray interface portion end  259 . First end  251  of user interface portion  252  may be coupled to a fixed portion of device  10  (e.g., first end  251  may be coupled to a portion of housing  18  or another component of device  10  whose position may be fixed with respect to housing  18 ) and second end  259  of tray interface portion  258  may be coupled to another fixed portion of device  10  (e.g., second end  259  may be coupled to a portion of housing  18  or another component of device  10  whose position may be fixed with respect to housing  18 ), while second end  253  of user interface portion  252  may be coupled to first end  257  of tray interface portion  258 . 
     As described above with respect to user interface portion  52  of ejector mechanism  50  of  FIGS. 2A-2E , user interface portion  252  of ejector mechanism  250  may be any suitable unitary component or collection of suitable components that may be capable deflecting, deforming, bending, springing, pivoting, translating, rotating, moving, or otherwise changing between a first user interface state or position (e.g., as shown in  FIGS. 8A ,  8 B,  8 C,  8 E,  9 A,  9 B,  9 C,  9 E,  10 , and  11 ) and a second user interface state or position (e.g., as shown in  FIGS. 8D and 9D ). User interface portion  252  may be made of any suitable material, such as rubber, plastic, metal, or any suitable combinations thereof. In some embodiments, user interface portion  252  may be a single component made of any suitable material while, in other embodiments, user interface portion  252  may be several distinct components. Different portions of user interface portion  252  may be flexible or rigid. For example, a first portion of user interface portion  252  at or near first end  251  may be rigid (e.g., for coupling to a portion of housing  18 ), while another portion of user interface portion  252  may be flexible (e.g., for bending or deflecting from the first user interface state to the second user interface state). 
     Moreover, as described above with respect to tray interface portion  58  of ejector mechanism  50  of  FIGS. 2A-2E , tray interface portion  258  of ejector mechanism  250  may be any suitable unitary component or collection of suitable components that may be capable of deflecting, deforming, bending, springing, pivoting, translating, rotating, moving, or otherwise changing between a first tray interface state or position (e.g., as shown in  FIGS. 8A ,  8 B,  8 C,  8 E,  9 A,  9 B,  9 C,  9 E,  10 , and  11 ) and a second tray interface state or position (e.g., as shown in  FIGS. 8D and 9D ). Tray interface portion  258  may be made of any suitable material, such as rubber, plastic, metal, or any suitable combinations thereof. In some embodiments, tray interface portion  258  may be a single component made of any suitable material while, in other embodiments, tray interface portion  258  may be several distinct components. Different portions of tray interface portion  258  may be flexible or rigid. For example, a first portion of tray interface portion  258  at or near second end  259  may be rigid (e.g., for coupling to a portion of housing  18 ), while another portion of tray interface portion  258  may be flexible (e.g., for bending or deflecting from the first tray interface state to the second tray interface state). 
     For example, as shown in  FIGS. 8A-11 , user interface portion  252  may include one or more user interface plates (e.g., a plate  272 ) and/or one or more user interface retraction mechanisms (e.g., a retraction mechanism  282 ). User interface portion  252  may extend between first user interface portion end  251  and second user interface portion end  253 , and first end  251  may be fixed or otherwise coupled to inner surface  18   i  of wall  18   b  by one or more suitable mountings  261  (e.g., one or more welding or bonding locations, cladding, insert molding, screws, fasteners, rivets, hooks, tabs, holes, etc.). When user interface portion  252  is in its first user interface state (e.g., as shown in  FIGS. 8A ,  8 B,  8 C,  8 E,  9 A,  9 B,  9 C,  9 E,  10 , and  11 ), user interface portion  252  may extend against and along inner surface  18   i  of wall  18   b  from first end  251  towards second end  253 . In this first user interface state, user interface portion  252  may extend across and block at least a portion of user interface opening  17  provided through inner surface  18   i , such that user interface portion  252  may be configured to press against housing  18  about user interface opening  17  for preventing debris from entering into housing  18  through user interface opening  17  when user interface portion  252  is in its first user interface state. 
     Moreover, as shown in  FIGS. 8A-11 , tray interface portion  258  may include a beam (e.g., a beam  292 ) that may extend between first tray interface portion end  257  and second tray interface portion end  259 , and second end  259  may be fixed or otherwise coupled to inner surface  18   i  of wall  18   k  by one or more suitable mountings  269  (e.g., one or more welding or bonding locations, cladding, insert molding, screws, fasteners, rivets, hooks, tabs, holes, etc.). When tray interface portion  258  is in its first tray interface state (e.g., as shown in  FIGS. 8A ,  8 B,  8 C,  8 E,  9 A,  9 B,  9 C,  9 E,  10 , and  11 ), tray interface portion  258  may extend across at least a portion of module housing opening  19  from second end  259  towards first end  257 . In this first tray interface state, tray interface portion  258  may extend across at least a portion of module housing opening  19 , such that tray interface portion  258  may interact with at least a portion of tray  20  when tray  20  is inserted through module housing opening  19  and into connector  40 . 
     In some embodiments, first end  251  of user interface portion  252  and second end  259  of tray interface portion  258  may be fixed with respect to one another or be at least partially constrained with respect to one another. Each one of first end  251  and second end  259  may be fixed to or have its movement at least partially constrained by any portion of device  10  (e.g., housing  18 , connector  40 , etc.). First end  251  may be fixed to or have its movement at least partially constrained/restrained by a first portion of device  10  at a first location within housing  18  by mounting  261  and second end  259  may be fixed to or otherwise have its movement at least partially constrained/restrained by a second portion of device  10  at a second location within housing  18  by mounting  269 . 
     First end  257  of tray interface portion  258  may be coupled to second end  253  of user interface portion  252  in any suitable manner using any suitable coupling  255 . Coupling  255  may allow constrained relative motion between user interface portion  252  and tray interface portion  258 , such that user interface portion  252  may change between its first and second user interface states when tray interface portion  258  may change between its first and second tray interface states, and vice versa. Therefore, coupling  255  may allow for ejector mechanism  250  to change between a first ejector mechanism state (e.g., when each one of user interface portion  252  and tray interface portion  258  is in its respective first state) and a second ejector mechanism state (e.g., when each one of user interface portion  252  and tray interface portion  258  is in its respective second state). For example, as shown in  FIGS. 8A-11 , coupling  255  formed between second end  253  of user interface portion  252  and first end  257  of tray interface portion  258  may be a hinge bearing, such that first end  257  and second end  253  may each relatively rotate about an axis A′ of coupling  255  (see, e.g., axis A′ of  FIGS. 8A ,  8 D, and  11 ). 
     The tendency for ejector mechanism  250  to change between its first and second ejector mechanism states (e.g., the tendency for user interface portion  252  and tray interface portion  258  to change between their respective first and second states), may be defined by one or more material characteristics of user interface portion  252  and/or tray interface portion  258 , by one or more characteristics of mounting  261  and/or mounting  269 , and/or by one or more characteristics of coupling  255 . For example, in some embodiments, the material characteristics of user interface portion  252  and the characteristics of mounting  261  may be such that, absent any external forces acting on user interface portion  252  (e.g., any user input force provided by user input tool  98  or any force provided by tray interface portion  258  via coupling  255 ), user interface portion  252  may not be biased to exist in one user interface state or the other. That is, if first user interface portion end  251  of a rigid user interface portion  252  is coupled to housing  18  using an unbiased free swinging hinge mounting  261 , such a user interface portion  252  may have no tendency to move in either the direction of arrow U 1 ′ from its second user interface state to its first user interface state or in the direction of arrow U 2 ′ from its first user interface state to its second user interface state, absent being coupled via coupling  255  to a tray interface portion  258  having a tendency to move, respectively, in either the direction of arrow T 1 ′ from its second tray interface state to its first tray interface state or in the direction of arrow T 2 ′ from its first tray interface state to its second tray interface state (see, e.g.,  FIGS. 8D and 8E ). Similarly, in other embodiments, the material characteristics of tray interface portion  258  and the characteristics of mounting  269  may be such that, absent any external forces acting on tray interface portion  258  (e.g., any tray input force provided by tray  20  or any force provided by user interface portion  252  via coupling  255 ), tray interface portion  258  may not be biased to exist in one tray interface state or the other. That is, if second tray interface portion end  259  of a rigid tray interface portion  258  is coupled to housing  18  using an unbiased free swinging hinge mounting  269 , such a tray interface portion  258  may have no tendency to move in either the direction of arrow T 1 ′ from its second tray interface state to its first tray interface state or in the direction of arrow T 2 ′ from its first tray interface state to its second tray interface state, absent being coupled via coupling  255  to a user interface portion  252  having a tendency to move, respectively, in either the direction of arrow U 1 ′ from its second user interface state to its first user interface state or in the direction of arrow U 2 ′ from its first user interface state to its second user interface state. In yet other embodiments, user interface portion  252  and tray interface portion  258  may each be independently biased to exist in one of their two respective states, such that, when they are coupled via coupling  255 , the tendency of ejector mechanism  250  to move in either the direction of arrow E 1 ′ from its second ejector mechanism state to its first ejector mechanism state or in the direction of arrow E 2 ′ from its first ejector mechanism state to its second ejector mechanism state may be based on the combination of the independent tendencies of user interface portion  252  and tray interface portion  258  to do so. Any suitable tension may exist between mountings  261  and  269  to bias user interface portion  252  and/or tray interface portion  258  such that ejector mechanism  250  may remain in a particular ejector mechanism state when an input force (e.g., a user input force and/or a tray input force) is not applied to ejector mechanism  150 . 
     For example, as shown in  FIGS. 8A and 9A , before any portion of tray  20  has been inserted into housing  18 , before any user input force has been applied to user interface portion  252 , and before any tray input force has been applied to tray interface portion  258 , ejector mechanism  250  may be configured to be in its first ejector mechanism state. Therefore, as shown, when ejector mechanism  250  is in its first ejector mechanism state, user interface portion  252  may extend along inner surface  18   i  and across at least a portion of user interface opening  17 , and tray interface portion  258  may extend across at least a portion of module housing opening  19 . In this first ejector mechanism state, ejector mechanism  250  may be biased such that user interface portion  252  (e.g., plate  272 ) may exert a force in the direction of arrow U 1 ′ on housing  18  or on any other suitable portion of device  10 , and/or such that tray interface portion  258  may exert a force in the direction of arrow T 1 ′ along housing  18  or on any other suitable portion of device  10 . In other embodiments, neither user interface portion  252  nor tray interface portion  258  may be exerting any force in the directions of respective arrows U 1 ′ and T 1 ′ when ejector mechanism  250  is in its first ejector mechanism state. 
     Once tray  20  has been initially inserted through opening  19  and into housing  18  in the direction of arrow I to a certain extent, as shown in  FIGS. 8B and 9B , for example, a portion of tray  20  may not interact with a portion of tray interface portion  258  such that tray interface portion  258  may remain in its first tray interface state. For example, as shown, when tray interface portion  258  is in its first tray interface state, a portion of tray interface portion  258  may be deflected away from opening  19  and, thus, away from end  23  of tray  20  as tray  20  is initially inserted through opening  19  and into housing  18 . As shown in  FIGS. 8A and 9A , for example, a deflectable portion  293  of beam  292  may be in a deflected state that may be deflected away from a substantially linear path of beam  292  by a deflected distance D when tray interface portion  258  is in its first tray interface state. This deflected state may prevent leading edge  29  of tray  20  from contacting beam  292  as tray  20  is initially inserted through opening  19  and into housing  18  in the direction of arrow I. 
     However, once tray  20  has been fully inserted into housing  18  in the direction of arrow I, such that tray  20  may be in its fully loaded position of  FIGS. 8C and 9C , for example, tray interface portion  258  may be configured to contact a portion of tray  20  while remaining in its first tray interface state. For example, as shown, a portion of deflectable portion  293  of beam  292  of tray interface portion  258  may contact leading edge  29  of tray  20  once tray  20  reaches its fully loaded position (e.g., a position whereby retention members  42   a  and  42   b  may retain tray  20  in its fully loaded position). In some embodiments, such contact between tray interface portion  258  in its first tray interface state and tray  20  in its fully loaded position may be a passive contact (e.g., contact that may not reinforce itself via geometry or attraction (e.g., magnetic attraction)). In other embodiments, such contact between tray interface portion  258  in its first tray interface state and tray  20  in its fully loaded position may be an active contact (e.g., as shown in  FIG. 8C , deflectable portion  293  of beam  292  and leading edge  29  of tray  20  may respectively comprise attractable magnets  293   m  and  29   m , which may hold tray  20  in contact with beam  292 ). In such an active contact embodiment, tray interface portion  258  may be configured to hold tray  20  in its fully loaded position (e.g., without the aid of retention members  42   a  and  42   b ). In other embodiments, once tray  20  has been fully inserted into housing  18  in the direction of arrow I, such that tray  20  may be in its fully loaded position of  FIGS. 8C and 9C , for example, tray interface portion  258  may be configured to remain in its first tray interface state but may not contact tray  20 . 
     When retained in its fully loaded position of  FIGS. 8C and 9C , outer surface  21   x  of outer tray end  21  of tray  20  may be substantially flush and/or continuous with an outer surface  18   o  of housing  18  about opening  19 . In some embodiments, ejector mechanism  250  may be biased to remain in its first ejector mechanism state, such that ejector mechanism  250  may prevent tray  20  from being inserted further in the direction of arrow I. For example, deflectable portion  293  of beam  292  of tray interface portion  258  may be configured such that it is unable to be deflected further in the direction of arrow I (e.g., to increase deflected distance D), thereby preventing tray  20  from being inserted further in the direction of arrow I after initially contacting beam  292 . Additionally or alternatively, a portion of housing  18  may interact with tray  20  to prevent tray  20  from being inserted further in the direction of arrow I. For example, as shown in  FIG. 9C , housing  18  may include a housing key portion  18   y  that may be positioned within or adjacent an end of opening  19 , such that housing key portion  18   y  may obstruct and prevent a portion of tray  20  (e.g., a portion of outer tray end  21 ) from being inserted further in the direction of arrow I. Ejector mechanism  250  may be configured such that housing key portion  18   y  may interact with tray  20  at about the same moment that tray interface portion  258  may contact tray  20 . Moreover, housing key portion  18   y  may be positioned with respect to opening  19  such that tray  20  may not be inserted too far within opening  19  while tray  20  is upside down. For example, if tray  20  were attempted to be inserted into opening  19  in the direction of arrow I while bottom surface  25   b  of tray  20  was facing upwards (e.g., towards housing key portion  18   y  of  FIG. 9B ), then housing key portion  18   y  may be configured to obstruct and prevent ejector interface portion  28  from being inserted in the direction of arrow I beyond housing key portion  18   y . Therefore, a user may be prevented from inserting tray  20  too far into opening  18  when tray  20  is upside down. 
     Once tray  20  is held in its functional or fully loaded position of  FIGS. 8C and 9C , ejector mechanism  250  may be configured to receive a user input force, which may cause ejector mechanism  250  to change from its first ejector mechanism state to its second ejector mechanism state, which may at least partially eject tray  20  from device  10 . For example, as shown in  FIGS. 8D and 9D , first end  99  of user input tool  98  may be inserted through user interface opening  17  in housing  18  for applying a user input force in the direction of arrow UI onto a portion of user interface portion  252 . When this user input force is applied onto user interface portion  252 , user interface portion  252  may be configured to change from its first user interface state of  FIGS. 8C and 9C  to its second user interface state of  FIGS. 8D and 9D . When user interface portion  252  changes from its first user interface state to its second user interface state, the change may cause tray interface portion  258  to change from its first tray interface state of  FIGS. 8C and 9C  to its second tray interface state of  FIGS. 8D and 9D . This alteration of states by tray interface portion  258  may cause at least a portion of tray interface portion  258  to interact with tray  20  for at least partially ejecting tray  20  from device  10  in the direction of arrow O, as shown in  FIGS. 8D and 9D . 
     For example, as shown, when tray interface portion  258  changes from its first tray interface state to its second tray interface state for at least partially ejecting tray  20 , deflectable portion  293  of beam  292  of tray interface portion  258  may change from its deflected state to an undeflected or straight state (e.g., by reducing or eliminating deflected distance D). This movement of deflectable portion  293  of beam  292  of tray interface portion  258  from its deflected state to its undeflected state in the direction of arrow D 2 , when tray interface portion  258  changes from its first tray interface state to its second tray interface state, may push leading edge  29  of tray  20  in the direction of arrow D 2  for at least partially ejecting tray  20  from device  10  in the direction of arrow O. As shown in  FIGS. 8D and 9D , for example, device  10  may be configured such that, when tray interface portion  258  does change to its second tray interface state, ejector mechanism  250  may no longer retain tray  20  in its fully loaded position. For example, the force that may be applied by beam  292  onto tray  20  in the direction of arrow D 2  may be great enough to overcome any other retaining force that device  10  may use to retain tray  20  in its fully loaded position (e.g., any retention force that may be applied by retention members  42   a  and  42   b ). Moreover, when contact between tray interface portion  258  and tray  20  may be configured to be an active contact, such an active contact may be terminated when tray interface portion  258  changes to its second tray interface state. For example, when tray interface portion  258  changes to its second tray interface state (e.g., when deflectable portion  293  of beam  292  may change from its deflected state to its undeflected state), at least one of attractable magnets  293   m  and  29   m  may be weakened such that any active contact created by attractable magnets  293   m  and  29   m  may be terminated or overcome. This may allow tray  20  to be more easily removed from device  10 . 
     Then, once tray interface portion  258  is in its second tray interface state of  FIGS. 8D and 9D , and once the application of the user input force on user interface portion  252  is terminated, ejector mechanism  250  may be configured to return from its second ejector mechanism state to its first ejector mechanism state. For example, when first end  99  of user input tool  98  is at least partially withdrawn through user interface opening  17  in the direction of arrow UO for terminating the application of a user input force on a portion of user interface portion  252  (e.g., on cosmetic surface portion  279  of plate  272 ), user interface portion  252  may be configured to return from its second user interface state of  FIGS. 8D and 9D  to its first user interface state of  FIGS. 8E and 9E . This change of user interface portion  252  from its second user interface state to its first user interface state may cause tray interface portion  258  to change from its second tray interface state of  FIGS. 8D and 9D  to its first tray interface state of  FIGS. 8E and 9E  and, thus, may cause deflectable portion  293  of beam  292  of tray interface portion  258  to move in the direction of arrow D 1  from its undeflected state of  FIGS. 8D and 9D  to its deflected state of  FIGS. 8E and 9E . 
     Therefore, ejector mechanism  250  of  FIGS. 8A-11  may be configured to change between a first ejector mechanism state (e.g., an ejector mechanism state that may include a first user interface state and a first tray interface state) and a second ejector mechanism state (e.g., an ejector mechanism state that may include a second user interface state and a second tray interface state), such that ejector mechanism  250  may receive, retain, and/or eject tray  20  and/or removable module  30 . For example, user interface portion  252  may be configured to change from the first user interface state to the second user interface state when a user input force is applied by a user onto user interface portion  252  (e.g., as shown in  FIGS. 8D and 9D ). User interface portion  252  may also be configured to change from the second user interface state to the first user interface state when the application of a user input force onto user interface portion  252  is terminated (e.g., as shown in  FIGS. 8E and 9E ). Moreover, tray interface portion  258  may be configured to change from the first tray interface state to the second tray interface state in response to user interface portion  252  changing from the first user interface state to the second user interface state (e.g., as shown in  FIGS. 8D and 9D ). Tray interface portion  258  may also be configured to change from the second tray interface state to the first tray interface state in response to user interface portion  252  changing from the second user interface state to the first user interface state (e.g., as shown in  FIGS. 8E and 9E ). In some embodiments, in response to user interface portion  252  receiving a user input force and thereby changing from the first user interface state to the second user interface state, the resultant change of tray interface portion  258  from the first tray interface state to the second tray interface state may cause tray interface portion  258  to at least partially eject tray  20  from connector  40  and/or opening  19  (e.g., as shown in  FIGS. 8D and 9D ). 
     As shown in  FIGS. 8A-11 , for example, user interface portion  252  may include a user interface plate  272  that may extend between a first end  271  and a second end  273 . First end  271  of user interface plate  272  may be fixed or otherwise coupled to housing  18  by at least one mounting component  261  (e.g., at least one weld or other suitable bonding element). Moreover, as shown in  FIGS. 8A-11 , for example, user interface portion  252  may alternatively or additionally include a user interface retraction mechanism  282  that may extend between a first end  281  and a second end  283 . First end  281  of user interface retraction mechanism  282  may be fixed or otherwise coupled to housing  18  by at least one mounting component  261  (e.g., at least one weld or other suitable bonding element). 
     For example, as shown, first end  281  of user interface retraction mechanism  282  may be fixed or otherwise coupled to inner surface  18   i  of wall  18   b , such that, when user interface portion  252  is in its first user interface state (e.g., as shown in  FIGS. 8A-8C ,  8 E,  9 A- 9 C,  9 E,  10 , and  11 ), user interface retraction mechanism  282  may extend against and along inner surface  18   i  of wall  18   b  towards second end  283 . In this first user interface state, user interface retraction mechanism  282  may extend about and beyond at least a portion of user interface opening  17  provided through inner surface  18   i . For example, retraction mechanism  282  may include an opening  285  through retraction mechanism  282  that may align with at least a portion of user interface opening  17  when user interface portion  252  is in its first user interface state. Moreover, as shown, first end  271  of user interface plate  272  may be fixed or otherwise coupled to first end  281  of retraction mechanism  282  and/or to inner surface  18   i  of wall  18   b , such that, when user interface portion  252  is in its first user interface state (e.g., as shown in  FIGS. 8A-8C ,  8 E,  9 A- 9 C,  9 E,  10 , and  11 ), user interface plate  272  may extend against and along retraction mechanism  282  towards second end  273 . In this first user interface state, user interface plate  272  may extend across opening  285  of retraction mechanism  282 , such that user interface portion  252  may be configured to press against housing  18  about user interface opening  17  for preventing debris from entering into housing  18  through user interface opening  17  when user interface portion  252  is in its first user interface state. For example, when user interface portion  252  is in its first user interface state, plate  272  may be configured to press against retraction mechanism  282  in the direction of arrow U 1 ′, such that retraction mechanism  282  may be held against inner surface  18   i  of wall  18   b , and such that cosmetic surface portion  279  of plate  272  may cover opening  285  and, thus, opening  17  for preventing debris from entering into housing  18  through user interface opening  17  when user interface portion  252  is in its first user interface state. In some embodiments, at least a portion of retraction mechanism  282  (e.g., a portion about opening  285 ) may be biased against inner surface  18   i  of wall  18   b  in both the first and second user interface states of user interface portion  252 . 
     In some embodiments, retraction mechanism  282  may include a flexible portion  284  that may relax and retract. For example, flexible portion  284  may be any suitable portion of retraction mechanism  282  that may be configured to bend or otherwise flex to alter a flexible distance between first end  281  and second end  283  of retraction mechanism  282  when user interface portion  252  changes between first and second user interface states (e.g., from a flexible distance F 1  of  FIG. 8C  to a flexible distance F 2  of  FIG. 8D ). In some embodiments, flexible portion  284  may allow retraction mechanism  282  to act as a retraction spring. In some embodiments, flexible portion  284  may be an elastomer or any other suitable material or combination of materials. As shown, plate  272  may include an opening  275  through plate  272  that may be aligned with flexible portion  284 , such that flexible portion  284  may extend through opening  275  and away from inner surface  18   i  of wall  18   b  for flexing. 
     Second end  283  of retraction mechanism  282  may be coupled to first end  257  of tray interface portion  258  (e.g., to a first end of beam  292 ) via coupling  255 . In some embodiments, when ejector mechanism is in the first ejector mechanism state of  FIG. 8C , at least one of beam  292  and retraction mechanism  282  may be biased or otherwise configured to change the distance between its two ends. For example, when ejector mechanism  250  is in the first ejector mechanism state of  FIG. 8C , beam  292  of tray interface portion  258  may be biased to extend first end  257  in the direction of arrow T 2 ′ away from fixed second end  259  (e.g., to extend the distance between the ends of beam  192  from distance B 1  of  FIG. 8C  to distance B 2  of  FIG. 8D ), such that tray interface portion  258  may change from its first tray interface state to its second tray interface state. As shown, this extension of the distance between the ends of beam  292  from distance B 1  of  FIG. 8C  to distance B 2  of  FIG. 8D  may reduce or eliminate deflected distance D of beam  292 , which may move deflectable portion  293  of beam  292  of tray interface portion  258  in the direction of arrow D 2  from its deflected state of  FIG. 8C  to its undeflected state of  FIG. 8D . Alternatively or additionally, when ejector mechanism  250  is in the first ejector mechanism state of  FIG. 8C , retraction mechanism  282  of user interface portion  252  may be biased to retract second end  283  in the direction of arrow T 2 ′ towards fixed first end  281  (e.g., to retract the distance between the ends of retraction mechanism  282  from distance F 1  of  FIG. 8C  to distance F 2  of  FIG. 8D ), such that user interface portion  252  may change from its first user interface state to its second user interface state. As shown, this retraction of the distance between the ends of retraction mechanism  282  from distance F 1  of  FIG. 8C  to distance F 2  of  FIG. 8D  may increase the size of flexible portion  284  that may retract through opening  275  of plate  272  from a first a retracted size S 1  to a second retracted size S 2 , which may move flexible portion  284  of retraction mechanism  282  of user interface portion  252  in the direction of arrow R 2  from an expanded state of  FIG. 8C  to a retracted state of  FIG. 8D . 
     In some embodiments, for example, ejector mechanism  250  may be configured such that the extension of the distance between the ends of beam  292  from distance B 1  of  FIG. 8C  to distance B 2  of  FIG. 8D  may extend end  257  of beam  292  from end  259  by an additional distance of about 0.15 millimeters to about 0.35 millimeters. Likewise, ejector mechanism  250  may be configured such that the retraction of the distance between the ends of retraction mechanism  282  from distance F 1  of  FIG. 8C  to distance F 2  of  FIG. 8D  may retract end  283  of retraction mechanism  282  closer to end  281  by a retraction distance of about 0.15 millimeters to about 0.35 millimeters. 
     User interface plate  272  may be configured to interact with retraction mechanism  282 , coupling  255 , and/or tray interface portion  258 , such that, when user interface portion  252  is in the first user interface state of  FIG. 8C , user interface plate  272  may prevent retraction mechanism  282  from retracting second end  283  in the direction of arrow T 2 ′ towards fixed first end  281  (e.g., from retracting the distance between the ends of retraction mechanism  282  from distance F 1  of  FIG. 8C  to distance F 2  of  FIG. 8D ) and, thus, may prevent beam  292  of tray interface portion  258  from extending first end  257  in the direction of arrow T 2 ′ away from fixed second end  259  (e.g., from extending the distance between the ends of beam  192  from distance B 1  of  FIG. 8C  to distance B 2  of  FIG. 8D ). For example, as shown in  FIG. 8C , when user interface portion  252  is in the first user interface state, second end  273  of user interface plate  272  may be biased to exert a force in the direction of arrow U 1 ′ on retraction mechanism  282 , which may hold at least a portion of retraction mechanism  282  (e.g., the portion of retraction mechanism  282  adjacent second end  283  and coupling  255 ) against inner surface  18   i  of wall  18   b.    
     However, as shown in  FIG. 8D , when user interface portion  252  changes from the first user interface state to the second user interface state (e.g., when first end  99  of user input tool  98  is inserted through user interface opening  17  in housing  18  and through opening  285  of retraction mechanism  282  for applying a user input force in the direction of arrow UI onto cosmetic surface portion  279  of plate  272 ), user interface plate  272  may pivot about pivot point P 1 ′ in the direction of arrow U 2 ′. When plate  272  pivots in the direction of arrow U 2 ′, second end  273  of plate  272  may be removed from a portion of the path along which retraction mechanism  282  may be biased to retract second end  283  in the direction of arrow T 2 ′ towards fixed first end  281  (e.g., to retract the distance between the ends of retraction mechanism  282  from distance F 1  of  FIG. 8C  to distance F 2  of  FIG. 8D ) and, thus, from a portion of the path along which beam  292  of tray interface portion  258  may be biased to extend first end  257  in the direction of arrow T 2 ′ away from fixed second end  259  (e.g., to extend the distance between the ends of beam  192  from distance B 1  of  FIG. 8C  to distance B 2  of  FIG. 8D ). Therefore, when user interface portion  252  changes to the second user interface state (e.g., when user input tool  98  applies a user input force in the direction of arrow UI onto plate  272 ), user interface plate  272  may be pushed out of a travel path of retraction mechanism  282  that may actively straighten a portion of beam  292  and/or that may allow a portion of beam  292  to straighten, thereby at least partially ejecting tray  20  from device  10  in the direction of arrow O. 
     Additionally or alternatively, when user interface portion  252  changes from the second user interface state of  FIG. 8D  to the first user interface state of  FIG. 8E  (e.g., when first end  99  of user input tool  98  is at least partially withdrawn through openings  285  and  17  in the direction of arrow U 0  for terminating the application of a user input force on cosmetic surface portion  279  of plate  272 ), user interface plate  272  may be biased to pivot about pivot point P 1 ′ in the direction of arrow U 1 ′. When plate  272  pivots in the direction of arrow U 1 ′, second end  273  of plate  272  may exert a force in the direction of arrow T 1 ′ on a portion of retraction mechanism  282  (e.g., second end  283 ) and/or on a portion of tray interface portion  258  (e.g., first end  257  of beam  292 ) and/or on a portion of coupling  255 . Therefore, when user interface portion  252  changes to the first user interface state (e.g., when an application of a user input force by user input tool  98  in the direction of arrow UI onto plate  272  is terminated), a portion of user interface plate  272  may be inserted into a travel path that may expand retraction mechanism  282  and that may deflect a portion of beam  292 . As shown, this expansion of retraction mechanism  282  may extend the distance between the ends of retraction mechanism  282  from distance F 2  of  FIG. 8D  to distance F 1  and, thus, may decrease the size of flexible portion  284  that may retract through opening  275  of plate  272  from second retracted size S 2  to first retracted size S 1 , which may move flexible portion  284  of retraction mechanism  282  of user interface portion  252  in the direction of arrow R 1  from a retracted of  FIG. 8D  to an expanded state of  FIG. 8E . 
     The geometry of second end  273  of user interface plate  272  and the geometry of at least one of second end  283  of retraction mechanism  282 , coupling  255 , and first send  257  of beam  292  may be configured such that they may smoothly interact with one another for inserting second end  273  into and removing second end  273  from a portion of the path along which retraction mechanism  282  may expand and retract. For example, as shown, a curved portion  273 ′ of second end  273  of user interface plate  272  may interact with a curved portion  283 ′ of second end  283  of retraction mechanism  282  when user interface portion  252  changes between first and second user interface states. 
     Although ejector mechanism  250  may have been described with respect to  FIGS. 8A-11  as being configured to change from its second ejector mechanism state of  FIGS. 8D and 9D  to its first ejector mechanism state of  FIGS. 8E and 9E  once application of a user input force by user input tool  98  in the direction of arrow UI onto plate  272  is terminated, ejector mechanism  250  may alternatively be configured to remain in its second ejector mechanism state until tray  20  is re-inserted into device  10 . For example, rather than being in its first ejector mechanism state during initial insertion of tray  20  (e.g., as shown in  FIGS. 8B and 9B ), ejector mechanism  250  may be configured to be in its second ejector mechanism state of  FIGS. 8D and 9D  during the initial insertion stage of tray  20  depicted in  FIGS. 8B and 9B  (e.g., the second ejector mechanism state of ejector mechanism  250  may be the ejector mechanism state for initial insertion of tray  20  into device  10 ). This may be done, for example, by configuring the bias of tray interface portion  258  and/or the bias of retraction mechanism  282  towards the second ejector mechanism state to be greater than the bias of user interface plate  272  towards the first ejector mechanism state. Therefore, for example, tray interface portion  258  may be relaxed when in its second state and held taut in its first state. In such embodiments, when tray  20  is initially inserted through opening  19  in the direction of arrow I, leading edge  29  of tray  20  may initially make contact with beam  292  while beam  292  is in its undeflected or straight state (e.g., while tray interface portion  258  is in its second tray interface state of  FIGS. 8D and 9D ). Once this initial contact has been made, tray  20  may apply a tray input force in the direction of arrow I onto tray interface portion  258  as tray  20  is further inserted into device  10 , which may cause tray interface portion  258  to change from its second tray interface state to its first tray interface state. For example, this tray input force may be applied in the direction of arrow I by leading edge  29  of tray  20  onto deflectable portion  293  of beam  292  of tray interface portion  258 , which may cause deflectable portion  293  to move in the direction of arrow D 1  from its undeflected state of  FIGS. 8D and 9D  to its deflected state of  FIGS. 8C and 9C , such that tray  20  may be held in its fully loaded position as described above. 
     As mentioned, the tendency for ejector mechanism  250  to change between its first and second ejector mechanism states (e.g., the tendency for user interface portion  252  and tray interface portion  258  to change between their respective first and second states), may be defined by one or more material characteristics of user interface portion  252  and/or tray interface portion  258 , by one or more characteristics of mounting  261  and/or mounting  269 , and/or by one or more characteristics of coupling  255 . For example, in some embodiments, the characteristics of mounting  261  and the characteristics of user interface plate  272  may be such that user interface plate  272  may be biased to remain in the first user interface state absent any external forces acting on user interface plate  272  (e.g., any user input force provided by user input tool  98  or any force provided by tray interface portion  258  via coupling  255  and/or retraction mechanism  282 ). For example, plate  272  may be a spring plate that may be biased to pivot about point P 1  in the direction of arrow U 1 ′ towards retraction mechanism  282 . Such a spring bias may also force retraction mechanism  282  and beam  292  in the direction of arrow T 1 ′, such that ejector mechanism  250  may tend to be in its first ejector mechanism state. Alternatively, in some embodiments, the characteristics of mounting  269  and the characteristics of beam  292  may be such that tray interface portion  258  may be biased to remain in the second tray interface state absent any external forces acting on tray interface portion  258  (e.g., any tray input force provided by tray  20  or any force provided by user interface plate  272  via coupling  255  and/or retraction mechanism  282 ). For example, beam  292  may be a deflectable beam that may be biased to straighten and expand the distance of end  257  from end  259  in the direction of arrow T 2 ′. Such a straightening bias (e.g., a relaxed position, a straight static beam without deflection, a straightening tendency of a non-formed beam, etc.) may also force end  273  of user interface plate  272  in the direction of arrow U 2 ′, such that ejector mechanism  250  may tend to be in its second ejector mechanism state. In yet other embodiments, beam  292 , retraction mechanism  282 , and plate  272  may each be independently biased to exist in one of their two respective states, such that, when they are coupled via coupling  255 , the tendency of ejector mechanism  250  to move from its second ejector mechanism state to its first ejector mechanism state or from its first ejector mechanism state to its second ejector mechanism state may be based on the combination of the independent tendencies of beam  292 , retraction mechanism  282 , and plate  272  to do so. Any suitable tension may exist between mountings  261  and  269  (e.g., between ends  251  and  259 ) to bias user interface portion  252  and/or tray interface portion  258  such that ejector mechanism  250  may remain in a particular ejector mechanism state when an input force (e.g., a user input force and/or a tray input force) is not applied to ejector mechanism  250 . For example, in some embodiments, when ejector mechanism  250  is in its first ejector mechanism state, at least one of user interface portion  252  and tray interface portion  258  may be relaxed in its first state, and when ejector mechanism  250  is in its second ejector mechanism state, at least one of user interface portion  252  and tray interface portion  258  may be pulled taut in its second state. By changing from a state of tautness to a state of relaxation (e.g., from a taut state having a first stress to a relaxed state having a second stress that may be lower than the first stress), tray interface portion  258  may impart an ejection force onto tray  20 . As another example, in some embodiments, when ejector mechanism  250  is in its first ejector mechanism state, at least one of user interface portion  252  and tray interface portion  258  may be held taut in its first state, and when ejector mechanism  250  is in its second ejector mechanism state, at least one of user interface portion  252  and tray interface portion  258  may be relaxed in its second state. By changing from a state of relaxation to a state of tautness (e.g., from a relaxed state having a first stress to a taut state having a second stress that may be greater than the first stress), tray interface portion  258  may impart an ejection force onto tray  20 . 
     In some embodiments, first end  251  of user interface portion  252  may be the only portion of user interface portion  252  that is coupled to any portion of housing  18 , connector  40 , or any other portion of device  10  other than tray interface portion  258 . Similarly, in some embodiments, second end  259  of tray interface portion  258  may be the only portion of tray interface portion  258  that is coupled to any portion of housing  18 , connector  40 , or any other portion of device  10  other than user interface portion  252 . That is, besides ends  251  and  259 , which may be distinct with tension therebetween, no other portion of ejector mechanism  250  may be coupled to any other portion of device  10 . Coupling  255  and ends  253  and  257  may be free from any other components of device  10  and may only be impacted by a removable entity or a user input tool. 
     In some embodiments, as shown in  FIGS. 12A-14 , for example, ejectable component assembly  16  may include an ejector mechanism  350 , which may be similar to ejector mechanism  50  of  FIGS. 2A-2E , for at least partially ejecting tray  20  and/or module  30  from connector  40  and/or housing  18 . Ejector mechanism  350  may include a user interface portion  352  and a tray interface portion  358 . User interface portion  352  may extend between a first user interface portion end  351  and a second user interface portion end  353 . Tray interface portion  358  may extend between a first tray interface portion end  357  and a second tray interface portion end  359 . First end  351  of user interface portion  352  may be coupled to a fixed portion of device  10  (e.g., first end  351  may be coupled to a portion of housing  18  or another component of device  10  whose position may be fixed with respect to housing  18 ) and second end  359  of tray interface portion  358  may be coupled to another fixed portion of device  10  (e.g., second end  359  may be coupled to a portion of housing  18  or another component of device  10  whose position may be fixed with respect to housing  18 ), while second end  353  of user interface portion  352  may be coupled to first end  357  of tray interface portion  358 . 
     As described above with respect to user interface portion  52  of ejector mechanism  50  of  FIGS. 2A-2E , user interface portion  352  of ejector mechanism  350  may be any suitable unitary component or collection of suitable components that may be capable deflecting, deforming, bending, springing, pivoting, translating, rotating, moving, or otherwise changing between a first user interface state or position (e.g., as shown in  FIGS. 12A-12C ,  12 E,  13 A- 13 C,  13 E, and  14 ) and a second user interface state or position (e.g., as shown in  FIGS. 12D and 13D ). User interface portion  352  may be made of any suitable material, such as rubber, plastic, metal, or any suitable combinations thereof. In some embodiments, user interface portion  352  may be a single component made of any suitable material while, in other embodiments, user interface portion  352  may be several distinct components. Different portions of user interface portion  352  may be flexible or rigid. For example, a first portion of user interface portion  352  at or near first end  351  may be rigid (e.g., for coupling to a portion of housing  18 ), while another portion of user interface portion  352  may be flexible (e.g., for bending or deflecting from the first user interface state to the second user interface state). 
     Moreover, as described above with respect to tray interface portion  58  of ejector mechanism  50  of  FIGS. 2A-2E , tray interface portion  358  of ejector mechanism  350  may be any suitable unitary component or collection of suitable components that may be capable of deflecting, deforming, bending, springing, pivoting, translating, rotating, moving, or otherwise changing between a first tray interface state or position (e.g., as shown in  FIGS. 12A-12C ,  12 E,  13 A- 13 C,  13 E, and  14 ) and a second tray interface state or position (e.g., as shown in  FIGS. 12D and 13D ). Tray interface portion  358  may be made of any suitable material, such as rubber, plastic, metal, or any suitable combinations thereof. In some embodiments, tray interface portion  358  may be a single component made of any suitable material while, in other embodiments, tray interface portion  358  may be several distinct components. Different portions of tray interface portion  358  may be flexible or rigid. For example, a first portion of tray interface portion  358  at or near second end  359  may be rigid (e.g., for coupling to a portion of housing  18 ), while another portion of tray interface portion  358  may be flexible (e.g., for bending or deflecting from the first tray interface state to the second tray interface state). 
     For example, as shown in  FIGS. 12A-14 , user interface portion  352  may include one or more user interface plates (e.g., a user interface plate  372 ). User interface portion  352  may extend between first user interface portion end  351  and second user interface portion end  353 , and first end  351  may be fixed or otherwise coupled to inner surface  18   i  of wall  18   b  by one or more suitable mountings  361  (e.g., one or more welding or bonding locations, cladding, insert molding, screws, fasteners, rivets, hooks, tabs, holes, etc.). When user interface portion  352  is in its first user interface state (e.g., as shown in  FIGS. 12A-12C ,  12 E,  13 A- 13 C,  13 E, and  14 ), user interface portion  352  may extend against and along inner surface  18   i  of wall  18   b  from first end  351  towards second end  353 . In this first user interface state, user interface portion  352  may extend across and block at least a portion of user interface opening  17  provided through inner surface  18   i , such that user interface portion  352  may be configured to press against housing  18  about user interface opening  17  for preventing debris from entering into housing  18  through user interface opening  17  when user interface portion  352  is in its first user interface state. 
     Moreover, as shown in  FIGS. 12A-14 , tray interface portion  358  may include a tray interface plate (e.g., a tray interface plate  392 ) that may extend between first tray interface portion end  357  and second tray interface portion end  359 , and second end  359  may be fixed or otherwise coupled to inner surface  18   i  of wall  18   k  by one or more suitable mountings  369  (e.g., one or more welding or bonding locations, cladding, insert molding, screws, fasteners, rivets, hooks, tabs, holes, etc.). When tray interface portion  358  is in its first tray interface state (e.g., as shown in  FIGS. 12A-12C ,  12 E,  13 A- 13 C,  13 E, and  14 ), tray interface portion  358  may extend across at least a portion of module housing opening  19  from second end  359  towards first end  357 . In this first tray interface state, tray interface portion  358  may extend across at least a portion of module housing opening  19 , such that tray interface portion  358  may interact with at least a portion of tray  20  when tray  20  is inserted through module housing opening  19  and into connector  40 . 
     In some embodiments, first end  351  of user interface portion  352  and second end  359  of tray interface portion  358  may be fixed with respect to one another or be at least partially constrained with respect to one another. Each one of first end  351  and second end  359  may be fixed to or have its movement at least partially constrained by any portion of device  10  (e.g., housing  18 , connector  40 , etc.). First end  351  may be fixed to or have its movement at least partially constrained/restrained by a first portion of device  10  at a first location within housing  18  by mounting  361  and second end  359  may be fixed to or otherwise have its movement at least partially constrained/restrained by a second portion of device  10  at a second location within housing  18  by mounting  369 . 
     First end  357  of tray interface portion  358  may be coupled to second end  353  of user interface portion  352  in any suitable manner using any suitable coupling  355 . Coupling  355  may allow constrained relative motion between user interface portion  352  and tray interface portion  358 , such that user interface portion  352  may change between its first and second user interface states when tray interface portion  358  may change between its first and second tray interface states, and vice versa. Therefore, coupling  355  may allow for ejector mechanism  350  to change between a first ejector mechanism state (e.g., when each one of user interface portion  352  and tray interface portion  358  is in its respective first state) and a second ejector mechanism state (e.g., when each one of user interface portion  352  and tray interface portion  358  is in its respective second state). For example, as shown in  FIGS. 12A-14 , coupling  355  formed between second end  353  of user interface portion  352  and first end  357  of tray interface portion  358  may be a seamless integrated coupling, such that user interface portion  352  and tray interface portion  358  may be a single unitary component extending between first end  351  and second end  359 . In other embodiments, coupling  355  may be a hinged bearing (e.g., to allow relative rotation of ends  353  and  357 ), a welded or bonded coupling, a rivet, a fastener, a screw, or any other suitable coupling. 
     The tendency for ejector mechanism  350  to change between its first and second ejector mechanism states (e.g., the tendency for user interface portion  352  and tray interface portion  358  to change between their respective first and second states), may be defined by one or more material characteristics of user interface portion  352  and/or tray interface portion  358 , by one or more characteristics of mounting  361  and/or mounting  369 , and/or by one or more characteristics of coupling  355 . For example, in some embodiments, the material characteristics of user interface portion  352  and the characteristics of mounting  361  may be such that, absent any external forces acting on user interface portion  352  (e.g., any user input force provided by user input tool  98  or any force provided by tray interface portion  358  via coupling  355 ), user interface portion  352  may not be biased to exist in one user interface state or the other. That is, if first user interface portion end  351  of a rigid user interface portion  352  is coupled to housing  18  using an unbiased free swinging hinge mounting  361 , such a user interface portion  352  may have no tendency to move in either the direction of arrow U 1 ″ from its second user interface state to its first user interface state or in the direction of arrow U 2 ″ from its first user interface state to its second user interface state, absent being coupled via coupling  355  to a tray interface portion  358  having a tendency to move, respectively, in either the direction of arrow T 1 ″ from its second tray interface state to its first tray interface state or in the direction of arrow T 2 ″ from its first tray interface state to its second tray interface state (see, e.g.,  FIGS. 12D and 12E ). Similarly, in other embodiments, the material characteristics of tray interface portion  358  and the characteristics of mounting  369  may be such that, absent any external forces acting on tray interface portion  358  (e.g., any tray input force provided by tray  20  or any force provided by user interface portion  352  via coupling  355 ), tray interface portion  358  may not be biased to exist in one tray interface state or the other. That is, if second tray interface portion end  359  of a rigid tray interface portion  358  is coupled to housing  18  using an unbiased free swinging hinge mounting  369 , such a tray interface portion  358  may have no tendency to move in either the direction of arrow T 1 ″ from its second tray interface state to its first tray interface state or in the direction of arrow T 2 ″ from its first tray interface state to its second tray interface state, absent being coupled via coupling  355  to a user interface portion  352  having a tendency to move, respectively, in either the direction of arrow U 1 ″ from its second user interface state to its first user interface state or in the direction of arrow U 2 ″ from its first user interface state to its second user interface state. In yet other embodiments, user interface portion  352  and tray interface portion  358  may each be independently biased to exist in one of their two respective states, such that, when they are coupled via coupling  355 , the tendency of ejector mechanism  350  to move from its second ejector mechanism state to its first ejector mechanism state or from its first ejector mechanism state to its second ejector mechanism state may be based on the combination of the independent tendencies of user interface portion  352  and tray interface portion  358  to do so. Any suitable tension may exist between mountings  361  and  369  (e.g., between ends  351  and  359 ) to bias user interface portion  352  and/or tray interface portion  358  such that ejector mechanism  350  may remain in a particular ejector mechanism state when an input force (e.g., a user input force and/or a tray input force) is not applied to ejector mechanism  350 . For example, in some embodiments, when ejector mechanism  350  is in its first ejector mechanism state, at least one of user interface portion  352  and tray interface portion  358  may be relaxed in its first state, and when ejector mechanism  350  is in its second ejector mechanism state, at least one of user interface portion  352  and tray interface portion  358  may be pulled taut in its second state. By changing from a state of tautness to a state of relaxation (e.g., from a taut state having a first stress to a relaxed state having a second stress that may be lower than the first stress), tray interface portion  358  may impart an ejection force onto tray  20 . As another example, in some embodiments, when ejector mechanism  350  is in its first ejector mechanism state, at least one of user interface portion  352  and tray interface portion  358  may be held taut in its first state, and when ejector mechanism  350  is in its second ejector mechanism state, at least one of user interface portion  352  and tray interface portion  358  may be relaxed in its second state. By changing from a state of relaxation to a state of tautness (e.g., from a relaxed state having a first stress to a taut state having a second stress that may be greater than the first stress), tray interface portion  358  may impart an ejection force onto tray  20 . 
     For example, as shown in  FIGS. 12A and 13A , before any portion of tray  20  has been inserted into housing  18 , before any user input force has been applied to user interface portion  352 , and before any tray input force has been applied to tray interface portion  358 , ejector mechanism  350  may be configured to be in its first ejector mechanism state. Therefore, as shown, when ejector mechanism  350  is in its first ejector mechanism state, user interface portion  352  may extend along inner surface  18   i  and across at least a portion of user interface opening  17 , and tray interface portion  358  may extend across at least a portion of module housing opening  19 . In this first ejector mechanism state, ejector mechanism  350  may be biased such that user interface portion  352  (e.g., plate  372 ) may exert a force in the direction of arrow U 1 ″ on housing  18  or on any other suitable portion of device  10 , and/or such that tray interface portion  358  may exert a force in the direction of arrow T 1 ″ along housing  18  or on any other suitable portion of device  10 . In other embodiments, neither user interface portion  352  nor tray interface portion  358  may be exerting any force in the directions of respective arrows U 1 ″ and T 1 ″ when ejector mechanism  350  is in its first ejector mechanism state. 
     Once tray  20  has been initially inserted through opening  19  and into housing  18  in the direction of arrow I to a certain extent, as shown in  FIGS. 12B and 13B , for example, a portion of tray  20  may not interact with a portion of tray interface portion  358  such that tray interface portion  358  may remain in its first tray interface state. For example, as shown, when tray interface portion  358  is in its first tray interface state, a portion of tray interface portion  358  may be deflected away from opening  19  and, thus, away from end  23  of tray  20  as tray  20  is initially inserted through opening  19  and into housing  18 . As shown in  FIGS. 12A and 13A , for example, a deflectable tray interface portion  393  of tray interface plate  392  may be in a deflected state that may be deflected away from a substantially linear path of plate  392  by a deflected tray interface distance TD when tray interface portion  358  is in its first tray interface state. This deflected state may prevent leading edge  29  of tray  20  from contacting tray interface plate  392  as tray  20  is initially inserted through opening  19  and into housing  18  in the direction of arrow I. 
     However, once tray  20  has been fully inserted into housing  18  in the direction of arrow I, such that tray  20  may be in its fully loaded position of  FIGS. 12C and 13C , for example, tray interface portion  358  may be configured to contact a portion of tray  20  while remaining in its first tray interface state. For example, as shown, a portion of deflectable tray interface portion  393  of tray interface plate  392  of tray interface portion  358  may contact leading edge  29  of tray  20  once tray  20  reaches its fully loaded position (e.g., a position whereby retention members  42   a  and  42   b  may retain tray  20  in its fully loaded position). In some embodiments, such contact between tray interface portion  358  in its first tray interface state and tray  20  in its fully loaded position may be a passive contact (e.g., contact that may not reinforce itself via geometry or attraction (e.g., magnetic attraction)). In other embodiments, such contact between tray interface portion  358  in its first tray interface state and tray  20  in its fully loaded position may be an active contact (e.g., as shown in  FIG. 12C , deflectable portion  393  of tray interface plate  392  and leading edge  29  of tray  20  may respectively comprise attractable magnets  393   m  and  29   m , which may hold tray  20  in contact with tray interface plate  392 ). In such an active contact embodiment, tray interface portion  358  may be configured to hold tray  20  in its fully loaded position (e.g., without the aid of retention members  42   a  and  42   b ). In other embodiments, once tray  20  has been fully inserted into housing  18  in the direction of arrow I, such that tray  20  may be in its fully loaded position of  FIGS. 12C and 13C , for example, tray interface portion  358  may be configured to remain in its first tray interface state but may not contact tray  20 . 
     When retained in its fully loaded position of  FIGS. 12C and 13C , outer surface  21   x  of outer tray end  21  of tray  20  may be substantially flush and/or continuous with an outer surface  18   o  of housing  18  about opening  19 . In some embodiments, ejector mechanism  350  may be biased to remain in its first ejector mechanism state, such that ejector mechanism  350  may prevent tray  20  from being inserted further in the direction of arrow I. For example, deflectable tray interface portion  393  of tray interface plate  392  of tray interface portion  358  may be configured such that it is unable to be deflected further in the direction of arrow I (e.g., to increase deflected tray interface distance TD in the direction of arrow T 1 ″), thereby preventing tray  20  from being inserted further in the direction of arrow I after initially contacting tray interface plate  392 . Additionally or alternatively, a portion of housing  18  may interact with tray  20  to prevent tray  20  from being inserted further in the direction of arrow I. For example, as shown in  FIG. 13C , housing  18  may include a housing key portion  18   y  that may be positioned within or adjacent an end of opening  19 , such that housing key portion  18   y  may obstruct and prevent a portion of tray  20  (e.g., a portion of outer tray end  21 ) from being inserted further in the direction of arrow I. Ejector mechanism  350  may be configured such that housing key portion  18   y  may interact with tray  20  at about the same moment that tray interface portion  358  may contact tray  20 . Moreover, housing key portion  18   y  may be positioned with respect to opening  19  such that tray  20  may not be inserted too far within opening  19  while tray  20  is upside down. For example, if tray  20  were attempted to be inserted into opening  19  in the direction of arrow I while bottom surface  25   b  of tray  20  was facing upwards (e.g., towards housing key portion  18   y  of  FIG. 13B ), then housing key portion  18   y  may be configured to obstruct and prevent ejector interface portion  28  from being inserted in the direction of arrow I beyond housing key portion  18   y . Therefore, a user may be prevented from inserting tray  20  too far into opening  18  when tray  20  is upside down. 
     Once tray  20  is held in its functional or fully loaded position of  FIGS. 12C and 13C , ejector mechanism  350  may be configured to receive a user input force, which may cause ejector mechanism  350  to change from its first ejector mechanism state to its second ejector mechanism state, which may at least partially eject tray  20  from device  10 . For example, as shown in  FIGS. 12D and 13D , first end  99  of user input tool  98  may be inserted through user interface opening  17  in housing  18  for applying a user input force in the direction of arrow UI onto a portion of user interface portion  352  (e.g., onto a cosmetic surface portion  379  of user interface plate  372 , which may cover opening  17  when in the first ejector mechanism state). When this user input force is applied onto user interface portion  352 , user interface portion  352  (e.g., plate  372 ) may be configured to change from its first user interface state of  FIGS. 12C and 13C  to its second user interface state of  FIGS. 12D and 13D . As shown in  FIGS. 12D and 13D , for example, a deflectable user interface portion  377  of user interface plate  372  may be deflected away from a substantially linear path of plate  372  by a deflected user interface distance UD from an undeflected state to a deflected state in the direction of arrow U 2 ″ when user interface portion  352  is in its second user interface state. When user interface portion  352  changes from its first user interface state to its second user interface state, the change may cause tray interface portion  358  to change from its first tray interface state of  FIGS. 12C and 13C  to its second tray interface state of  FIGS. 12D and 13D . This alteration of states by tray interface portion  358  may cause at least a portion of tray interface portion  358  to interact with tray  20  for at least partially ejecting tray  20  from device  10  in the direction of arrow O, as shown in  FIGS. 12D and 13D . 
     For example, as shown, when tray interface portion  358  changes from its first tray interface state to its second tray interface state for at least partially ejecting tray  20 , deflectable tray interface portion  393  of tray interface plate  392  of tray interface portion  358  may change from its deflected state to an undeflected or straight state (e.g., by reducing or eliminating deflected tray interface distance TD as shown in  FIGS. 12D and 13D ). This movement of deflectable tray interface portion  393  of tray interface plate  392  of tray interface portion  358  from its deflected state to its undeflected state in the direction of arrow T 2 ″, when tray interface portion  358  changes from its first tray interface state to its second tray interface state, may push leading edge  29  of tray  20  in the direction of arrow T 2 ″ for at least partially ejecting tray  20  from device  10  in the direction of arrow O. As shown in  FIGS. 12D and 13D , for example, device  10  may be configured such that, when tray interface portion  358  does change to its second tray interface state, ejector mechanism  350  may no longer retain tray  20  in its fully loaded position. For example, the force that may be applied by tray interface plate  392  onto tray  20  in the direction of arrow T 2 ″ may be great enough to overcome any other retaining force that device  10  may use to retain tray  20  in its fully loaded position (e.g., any retention force that may be applied by retention members  42   a  and  42   b ). Moreover, when contact between tray interface portion  358  and tray  20  may be configured to be an active contact, such an active contact may be terminated when tray interface portion  358  changes to its second tray interface state. For example, when tray interface portion  358  changes to its second tray interface state (e.g., when deflectable portion  393  of tray interface plate  392  may change from its deflected state to its undeflected state), at least one of attractable magnets  393   m  and  29   m  may be weakened such that any active contact created by attractable magnets  393   m  and  29   m  may be terminated or otherwise overcome. This may allow tray  20  to be more easily removed from device  10 . 
     Then, once tray interface portion  358  is in its second tray interface state of  FIGS. 12D and 13D , and once the application of the user input force on user interface portion  352  is terminated, ejector mechanism  350  may be configured to return from its second ejector mechanism state to its first ejector mechanism state. For example, when first end  99  of user input tool  98  is at least partially withdrawn through user interface opening  17  in the direction of arrow UO for terminating the application of a user input force on a portion of user interface portion  352  (e.g., on cosmetic surface portion  379  of user interface plate  372 ), user interface portion  352  may be configured to return from its second user interface state of  FIGS. 12D and 13D  to its first user interface state of  FIGS. 12E and 13E . For example, as shown, when user interface portion  352  changes from its second user interface state to its first user interface state, deflectable user interface portion  377  of user interface plate  372  of user interface portion  352  may change from its deflected state to an undeflected or straight state (e.g., by reducing or eliminating deflected user interface distance UD as shown in  FIGS. 12E and 13E ). This movement of deflectable user interface portion  377  of user interface plate  372  of user interface portion  352  from its deflected user interface state to its undeflected user interface state in the direction of arrow U 1 ″, when user interface portion  352  changes from its second user interface state to its first user interface state, may cause tray interface portion  358  to change from its second tray interface state of  FIGS. 12D and 13D  to its first tray interface state of  FIGS. 12E and 13E  and, thus, may cause deflectable tray interface portion  393  of tray interface plate  392  of tray interface portion  258  to move in the direction of arrow T 1 ″ from its undeflected tray interface state of  FIGS. 12D and 13D  to its deflected tray interface state of  FIGS. 12E and 13E . 
     Therefore, ejector mechanism  350  of  FIGS. 12A-14  may be configured to change between a first ejector mechanism state (e.g., an ejector mechanism state that may include a first user interface state and a first tray interface state) and a second ejector mechanism state (e.g., an ejector mechanism state that may include a second user interface state and a second tray interface state), such that ejector mechanism  350  may receive, retain, and/or eject tray  20  and/or removable module  30 . For example, user interface portion  352  may be configured to change from the first user interface state to the second user interface state when a user input force is applied by a user onto user interface portion  352  (e.g., deflectable user interface portion  377  of user interface plate  372  of user interface portion  352  may be configured to change from its undeflected tray interface state to its deflected tray interface state, as shown in  FIGS. 12D and 13D ). User interface portion  352  may also be configured to change from the second user interface state to the first user interface state when the application of a user input force onto user interface portion  352  is terminated (e.g., deflectable user interface portion  377  of user interface plate  372  of user interface portion  352  may be configured to change from its deflected tray interface state to its undeflected tray interface state, as shown in  FIGS. 12E and 13E ). Moreover, tray interface portion  358  may be configured to change from the first tray interface state to the second tray interface state in response to user interface portion  352  changing from the first user interface state to the second user interface state (e.g., deflectable tray interface portion  393  of tray interface plate  392  of tray interface portion  358  may be configured to change from its deflected tray interface state to its undeflected tray interface state, as shown in  FIGS. 12D and 13D ). Tray interface portion  358  may also be configured to change from the second tray interface state to the first tray interface state in response to user interface portion  352  changing from the second user interface state to the first user interface state (e.g., deflectable tray interface portion  393  of tray interface plate  392  of tray interface portion  358  may be configured to change from its undeflected tray interface state to its deflected tray interface state, as shown in  FIGS. 12E and 13E ). In some embodiments, in response to user interface portion  352  receiving a user input force and thereby changing from the first user interface state to the second user interface state, the resultant change of tray interface portion  358  from the first tray interface state to the second tray interface state may cause tray interface portion  358  to at least partially eject tray  20  from connector  40  and/or opening  19  (e.g., as shown in  FIGS. 12D and 13D ). 
     Although ejector mechanism  350  may have been described with respect to  FIGS. 12A-14  as being configured to change from its second ejector mechanism state of  FIGS. 12D and 13D  to its first ejector mechanism state of  FIGS. 12E and 13E  once application of a user input force by user input tool  98  in the direction of arrow UI onto user interface plate  372  is terminated, ejector mechanism  350  may alternatively be configured to remain in its second ejector mechanism state until tray  20  is re-inserted into device  10 . For example, rather than being in its first ejector mechanism state during initial insertion of tray  20  (e.g., as shown in  FIGS. 12B and 13B ), ejector mechanism  350  may be configured to be in its second ejector mechanism state of  FIGS. 12D and 13D  during the initial insertion stage of tray  20  depicted in  FIGS. 12B and 13B  (e.g., the second ejector mechanism state of ejector mechanism  350  may be the ejector mechanism state for initial insertion of tray  20  into device  10 ). This may be done, for example, by configuring the bias of tray interface plate  392  of tray interface portion  358  towards the second ejector mechanism state to be greater than the bias of user interface plate  372  of user interface portion  352  towards the first ejector mechanism state. In such embodiments, when tray  20  is initially inserted through opening  19  in the direction of arrow I, leading edge  29  of tray  20  may initially make contact with tray interface plate  392  while plate  392  is in its undeflected or straight state (e.g., while tray interface portion  358  is in its second tray interface state of  FIGS. 12D and 13D ). Once this initial contact has been made, tray  20  may apply a tray input force in the direction of arrow I onto tray interface portion  358  as tray  20  is further inserted into device  10 , which may cause tray interface portion  358  to change from its second tray interface state to its first tray interface state. For example, this tray input force may be applied in the direction of arrow I by leading edge  29  of tray  20  onto deflectable tray interface portion  393  of tray interface plate  392  of tray interface portion  358 , which may cause deflectable portion  393  to move in the direction of arrow T 1 ″ from its undeflected state of  FIGS. 12D and 13D  to its deflected state of  FIGS. 12C and 13C , such that tray  20  may be held in its fully loaded position as described above. 
     As mentioned, the tendency for ejector mechanism  350  to change between its first and second ejector mechanism states (e.g., the tendency for user interface portion  352  and tray interface portion  358  to change between their respective first and second states), may be defined by one or more material characteristics of user interface portion  352  and/or tray interface portion  358 , by one or more characteristics of mounting  361  and/or mounting  369 , and/or by one or more characteristics of coupling  355 . For example, in some embodiments, the characteristics of mounting  361  and the characteristics of user interface plate  372  may be such that user interface plate  372  may be biased to remain in the first user interface state absent any external forces acting on user interface plate  372  (e.g., any user input force provided by user input tool  98  or any force provided by tray interface portion  358  via coupling  355 ). For example, user interface plate  372  may be biased to remain in its undeflected state. Such a bias may also force tray interface plate  392  in the direction of arrow T 1 ″, such that ejector mechanism  350  may tend to be in its first ejector mechanism state. Alternatively, in some embodiments, the characteristics of mounting  369  and the characteristics of tray interface plate  392  may be such that tray interface portion  358  may be biased to remain in the second tray interface state absent any external forces acting on tray interface portion  358  (e.g., any tray input force provided by tray  20  or any force provided by user interface plate  372  via coupling  355 ). For example, tray interface plate  392  may be biased to remain in its undeflected state. Such a bias may also force user interface plate  372  in the direction of arrow U 2 ″, such that ejector mechanism  350  may tend to be in its second ejector mechanism state. In yet other embodiments, tray interface plate  392  and user interface plate  372  may each be independently biased to exist in one of their two respective states, such that, when they are coupled via coupling  355 , the tendency of ejector mechanism  350  to move from its second ejector mechanism state to its first ejector mechanism state or from its first ejector mechanism state to its second ejector mechanism state may be based on the combination of the independent tendencies of tray interface plate  392  and user interface plate  372  to do so. Any suitable tension may exist between mountings  361  and  369  (e.g., between ends  351  and  359 ) to bias user interface portion  352  and/or tray interface portion  358  such that ejector mechanism  350  may remain in a particular ejector mechanism state when an input force (e.g., a user input force and/or a tray input force) is not applied to ejector mechanism  350 . For example, in some embodiments, when ejector mechanism  350  is in its first ejector mechanism state, at least one of user interface portion  352  and tray interface portion  358  may be relaxed in its first state, and when ejector mechanism  350  is in its second ejector mechanism state, at least one of user interface portion  352  and tray interface portion  358  may be pulled taut in its second state. By changing from a state of tautness to a state of relaxation (e.g., from a taut state having a first stress to a relaxed state having a second stress that may be lower than the first stress), tray interface portion  358  may impart an ejection force onto tray  20 . As another example, in some embodiments, when ejector mechanism  350  is in its first ejector mechanism state, at least one of user interface portion  352  and tray interface portion  358  may be held taut in its first state, and when ejector mechanism  350  is in its second ejector mechanism state, at least one of user interface portion  352  and tray interface portion  358  may be relaxed in its second state. By changing from a state of relaxation to a state of tautness (e.g., from a relaxed state having a first stress to a taut state having a second stress that may be greater than the first stress), tray interface portion  358  may impart an ejection force onto tray  20 . 
     In some embodiments, first end  351  of user interface portion  352  may be the only portion of user interface portion  352  that is coupled to any portion of housing  18 , connector  40 , or any other portion of device  10  other than tray interface portion  358 . Similarly, in some embodiments, second end  359  of tray interface portion  358  may be the only portion of tray interface portion  358  that is coupled to any portion of housing  18 , connector  40 , or any other portion of device  10  other than user interface portion  352 . That is, besides ends  351  and  359 , which may be distinct with tension therebetween, no other portion of ejector mechanism  350  may be coupled to any other portion of device  10 . Coupling  355  and ends  353  and  357  may be free from any other components of device  10  and may only be impacted by a removable entity or a user input tool. 
     In some embodiments, user interface portion  352  and tray interface portion  358  may together may be any suitable unitary component that may be capable of deflecting, deforming, bending, springing, pivoting, translating, rotating, moving, or otherwise changing between a first ejector mechanism state or position (e.g., as shown in  FIGS. 12A-12C ,  12 E,  13 A- 13 C,  13 E, and  14 ) and a second ejector mechanism state or position (e.g., as shown in  FIGS. 12D and 13D ). For example, both user interface plate  372  and tray interface plate  392  may be made of any suitable material, such as rubber, plastic, metal, or any suitable combinations thereof. In some embodiments, one or both of plates  372  and  392  may be made of a woven material (e.g., Kevlar™) and may be treated with a rubber material and/or impregnated with a polyurethane plastic (e.g., a thermoplastic polyurethane), such that one or both of plates  372  and  392  may be similar to a rubber band with internal woven material. In some other embodiments, one or both of plates  372  and  392  may be made of a spring steel or other suitable material, and one or both of plates  372  and  392  may be conductive or electrically isolated. In some embodiments, user interface plate  372  and tray interface plate  392  may be formed separately (e.g., by the same or different processes and/or with the same or different materials), and then plates  372  and  392  may be joined together (e.g., by coupling  355 ) using any suitable technique, such as welding, cladding, crimping, bonding, gluing, fusing, adhering, and the like. 
     Moreover, in some embodiments, as shown, a backing plate  382  may be provided to reinforce at least a portion of user interface portion  352 . For example, as shown, backing plate  382  may be positioned at least along a portion of the backside of user interface plate  372  that may be opposite to cosmetic surface portion  379 . Backing plate  382  may be coupled to user interface plate  372  by one or more suitable mountings  363  (e.g., one or more welding or bonding locations, cladding, crimping, gluing, fusing, adhering, etc.). In some embodiments, user interface plate  372  may be flexible sheet metal or any other suitable material or combination of materials, and backing plate  382  may be a laminate that may be welded or otherwise coupled to user interface plate  372  via one or more mountings  363  for increasing the rigidity of the portion of user interface plate  372  that may receive a user input tool force in the direction of arrow UI. 
     In some embodiments, as shown in  FIG. 14 , user interface plate  372  may include an input tool receiving section  376  (e.g., a section that may include cosmetic surface portion  379 ) and at least a first extension section  374  that may extend from input tool receiving section  376  towards first end  351  of user interface portion  352  and that may be coupled to device  10  using one or more suitable mountings  361 . Moreover, in some embodiments, as shown, user interface plate  372  may also include a second extension section  375  that may extend from input tool receiving section  376  towards first end  351  of user interface portion  352  and that may be coupled to device  10  using one or more suitable mountings  361 . First extension section  374  and second extension section  375  may be distinct, may extend from different portions of input tool receiving section  376 , and may be coupled to different portions of device  10  (e.g., by different mountings  361 ). 
     Moreover, in some embodiments, as shown in  FIG. 14 , deflectable tray interface portion  393  of tray interface plate  392 , when in its deflected state, may define a first deflected perimeter  394  along a first edge  396  of tray interface plate  392  and a second deflected perimeter  395  along a second edge  397  of tray interface plate  392 . As shown in  FIGS. 13A and 14 , first edge  396  and second edge  397  may be on opposite sides of tray interface plate  392 , first deflected perimeter  394  and second deflected perimeter  395  may be the same length and geometry, and each one of first deflected perimeter  394  and second deflected perimeter  395  may define the same deflected tray interface distance TD when tray interface plate  392  is in its deflected tray interface state. However, in other embodiments, as shown in  FIGS. 15 and 15A , an ejector mechanism  350 ′ may be provided that may be substantially identical to ejector mechanism  350  of  FIGS. 12A-14 , except that deflectable tray interface portion  393 ′ of tray interface plate  392 ′, when in its deflected state, may define a first deflected perimeter  394 ′ along a first edge  396 ′ of tray interface plate  392 ′ and a second deflected perimeter  395 ′ along a second edge  397 ′ of tray interface plate  392 ′, such that first deflected perimeter  394 ′ may be shorter and/or of a different geometry than second deflected perimeter  395 ′. In such an embodiment, first deflected perimeter  394 ′ may define a first deflected tray interface distance TD 1  at first edge  396 ′ and second deflected perimeter  395 ′ may define a second deflected tray interface distance TD 2  at second edge  397 ′ that may be greater than first deflected tray interface distance TD 1  when tray interface plate  392 ′ is in its deflected tray interface state of  FIG. 15 . Distance TD 1  of  FIG. 15A  may be less than distance TD of  FIGS. 13A and 14 , such that edge  396 ′ of ejector mechanism  350 ′ may be held closer than edge  396  of ejector mechanism  350  to inner surface  18   i  of housing  18 . Edge  396 ′ may reach peak tension and may straighten sooner than edge  397 ′, which may create a different ejection force than edges  396  and  397 , which may straighten at the same time. 
     It is to be understood that any portion of any user interface portion of any ejector mechanism may be provided as an independent element of the ejector mechanism or may be provided as a single unitary element along with any portion of any tray interface portion of the ejector mechanism. Therefore, in some embodiments, an ejector mechanism may be provided with a single element that may function as a user interface portion and a tray interface portion. 
     It is to be understood that, although ejectable component assembly  16  has been described as including a connector  40  and a tray  20  for loading a removable module  30  within connector  40 , tray  20  may be unnecessary and any removable module to be inserted into connector  40  may be shaped with some or all of the features of tray  20 . For example, as shown in  FIGS. 16 and 17 , a removable module  30 ′ can be provided that may be substantially the same as removable module  30 , but that also can include one or more of a first end  21 ′ that may be shaped similarly to first tray end  21  of tray  20 , a second end  23 ′ that may be shaped similarly to second end  23  of tray  20 , grooves  29   a ′ and  29   b ′ that may be shaped similarly to grooves  29   a  and  29   b  of tray  20 , an ejector interface portion  28 ′ that may shaped similarly to ejector interface portion  28  of tray  20 , a securement feature  27 ′ that may shaped similarly to securement feature  27  of tray  20 , and a leading edge  29 ′ that may shaped similarly to leading edge  29  of tray  20 , such that module  30 ′ may be inserted into and ejected from device  10  in the same way that tray  20  may be inserted into and ejected from device  10 . Therefore, a tray input force that may be applied by a tray, as described above with respect to  FIGS. 1-15A , may similarly be referred to as a removable entity input force that may be applied by a removable entity (e.g., by removable module  30 ). 
     While there have been described systems and methods for ejecting removable modules from electronic devices, it is to be understood that many changes may be made therein without departing from the spirit and scope of the invention. Insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalently within the scope of the claims. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. It is also to be understood that various directional and orientational terms such as “up and “down,” “front” and “back,” “top” and “bottom,” “left” and “right,” “length” and “width,” and the like are used herein only for convenience, and that no fixed or absolute directional or orientational limitations are intended by the use of these words. For example, the devices of this invention can have any desired orientation. If reoriented, different directional or orientational terms may need to be used in their description, but that will not alter their fundamental nature as within the scope and spirit of this invention. Moreover, an electronic device constructed in accordance with the principles of the invention may be of any suitable three-dimensional shape, including, but not limited to, a sphere, cone, octahedron, or combination thereof, rather than a hexahedron, as illustrated by  FIGS. 1-17 . 
     Therefore, those skilled in the art will appreciate that the invention can be practiced by other than the described embodiments, which are presented for purposes of illustration rather than of limitation.
