Title: Mount for a computer peripheral device

Description:
BACKGROUND 
     Computer peripheral devices, such as cameras, can be positioned with respect to another device, such as a display monitor, using a mount. A user may position the mount on the display monitor so that the user is in view of the camera while the user views the display monitor. However, articulation of the camera while positioned on the display monitor may cause the mount to become unstable or fall off of the display monitor. Improvements in mounts are needed to provide more secure attachment of the mounts to display monitors. 
     BRIEF SUMMARY 
     In certain embodiments, a camera mounting system, for mounting a camera to a display monitor includes a clip body that can be coupled to a rear surface of the display monitor and a bracket assembly. The bracket assembly includes a first portion that can be coupled to the camera. The first portion includes a base and a lip extending from the base. The base can be supported on a top surface of the display monitor and the lip is can contact a front surface of the display monitor and limit movement of the bracket assembly in a first horizontal direction perpendicular to the front surface of the display monitor. A second portion is coupled to the first portion and can be releasably coupled to the clip body with the clip body coupled to the rear surface of the monitor in order to prevent movement of the bracket assembly in the first horizontal direction and prevent rotation of the base relative to the display monitor. The camera mounting system can also include the camera coupled to the first portion of the bracket assembly. With the second portion coupled to the clip body and with the clip body coupled to the rear surface of the monitor, a center of gravity of the assembly of the camera coupled to the bracket assembly is positionable in front of a forward edge of the top surface of the display monitor while the first portion is supported on the top surface of the display monitor without causing the bracket assembly to rotate forward. The first portion includes a hinge coupled to the base that can allow the camera to be rotated relative to the display monitor with the base supported on the top surface of the display monitor. The hinge and the coupling of the second portion to the clip body can allow rotation of the camera from a first position to a second position, relative to the display monitor, by a user manipulating the camera, without the user manipulating the bracket assembly, and without causing the base to rotate relative to the display monitor. In the first position the camera can be aimed at a user in front of the display monitor, and in the second position the camera can be aimed a document on a surface below the display monitor. In the first position the center of gravity of the assembly of the camera coupled to the bracket assembly is positioned over the top surface of the display monitor, and in the second position the center of gravity of the assembly of the camera coupled to the bracket assembly is positioned in front of the top surface of the display monitor. The assembly of the camera coupled to the bracket assembly can be mounted to a second display monitor with the first portion supported on a top surface of the second display monitor, the second portion contacting a rear surface of the second display monitor, and the second portion not coupled to a clip body. The clip body includes an adhesive surface, and the clip body can be coupled in a releasable manner via the adhesive surface adhering to the rear surface of the display monitor. The clip body defines tracks configured to receive edges of a portion of the second portion in order to slidably releaseably couple the second portion to the clip body in order to prevent movement of the bracket assembly in the first horizontal direction and prevent rotation of the base relative to the display monitor.

     DETAILED DESCRIPTION 
     Aspects of the present disclosure relate generally to computer peripheral devices, and more particularly to a mount for mounting a camera to a display monitor, according to certain embodiments. 
     In the following description, various examples of the mount are described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will be apparent to one skilled in the art that certain embodiments may be practiced or implemented without every detail disclosed. Furthermore, well-known features may be omitted or simplified in order to prevent any obfuscation of the novel features described herein. 
     The following high level summary is intended to provide a basic understanding of some of the novel innovations depicted in the figures and presented in the corresponding descriptions provided below. Many of the embodiments relate to novel mounts for webcams. The mount, which may be referred to as a bracket assembly, can include a first portion with a lip that can contact a front surface of a display monitor and a bottom surface that can contact a top surface of the display monitor. The bracket assembly can also include a second portion that can couple to a clip body, which can couple to a rear surface of the display monitor. With the second portion coupled to the clip body, the mount may be securely attached to the display monitor and may allow the webcam to be rotated to a desired position with respect to the display monitor. The mount may also be securely attached to the display monitor without the clip body, with the second portion contacting the rear surface of the display monitor, but the clip body can provide additional prevention of rotation and translation of the mount when coupled to the display monitor. 
     In some embodiments, the concepts described above can be implemented, for instance, by a bracket assembly comprising a first portion that includes a base and a lip. The base can be a top bracket portion that includes a main body portion. The main body portion defines a front edge, a rear edge, and a bottom surface extending between the front edge and the rear edge. The top bracket portion can also include a front tab, which can be the lip, extending from the front edge of the main body portion. The front tab can define a first rearward facing surface forming an angle with the bottom surface. The top bracket portion can couple to the first device, which may be a camera. The bracket assembly can also include a second portion that includes an upper rear arm portion coupled to the rear edge of the of the main body portion and a lower rear arm portion coupled to the upper rear arm portion so that the upper rear arm portion is positioned between the main body portion and the lower rear arm portion. A clip body of the bracket assembly can be releasably coupled to the lower rear arm portion and can define a second rearward facing surface facing the lower rear arm portion and a forward facing surface opposite the second rearward facing surface. The second device, which may be a display monitor, can include a housing defining a housing front surface, a housing rear surface facing opposite the housing front surface, and a housing top surface extending between the housing front surface and the housing rear surface. The bracket assembly can be supported by and coupled to the second device with the bottom surface contacting the housing top surface, the first rearward facing surface contacting the housing front surface, and the forward facing surface of the clip body coupled to and contacting the housing rear surface. 
     It is to be understood that this high level summary is presented to provide the reader with a baseline understanding of some of the novel aspects of the present disclosure and a roadmap to the details that follow. This high level summary in no way limits the scope of the various embodiments described throughout the detailed description and each of the figures referenced above are further described below in greater detail and in their proper scope. 
     Embodiments of a Package for a Computer Peripheral Device 
       FIG.  1 A  shows a cross-sectional view of an example of a bracket assembly  100  for mounting a first device to a second device, according to certain embodiments.  FIG.  1 B  shows a perspective view of the bracket assembly  100 . As an example, the bracket assembly  100  can couple a camera (first device) to a display monitor (second device). The bracket assembly  100  can include a first portion and a second portion. The first portion is a top bracket portion  102  and the second portion includes an upper rear arm portion  116  and a lower rear arm portion  118 . The top bracket portion  102  is coupled to the upper rear arm portion  116  that is coupled to the lower rear arm portion  118 , which is coupled to a clip body  120 . 
     According to an XYZ coordinate system, the top bracket portion  102  can be orientated in an XY plane, with a bottom surface  110  of the top bracket portion  102  facing in a negative Z direction, i.e. downward, which can correspond to gravity. The top bracket portion  102  can include a base, such as main body portion  104  that defines a front edge  106 , a rear edge  108 , and the bottom surface  110 . Between the front edge  106  and the rear edge  108 , the main body portion  104  can be substantially rectangular. A length of the main body portion  104  in the Y direction can be longer than a depth of the display monitor between a display surface of the display monitor and a rear surface of the display monitor. For example, the main body portion  104  may be between 0.25 inches and 7 inches long. A width of the main body portion  104  in the X direction may be less than the length. The top bracket portion  102  can also include a lip, such as front tab  112 , extending from the front edge  106  of the main body portion  104 . The front tab  112  can be rectangular and extend in the negative Z direction from the front edge  106 . A width of the front tab  112  can be the same as the width of the main body portion  104 , but a length of the front tab  112  may be short, such as less than one inch in the Z direction. The front tab  112  can define a first rearward facing surface  114  that can form an angle with the bottom surface  110 . The first rearward facing surface  114  can face in a positive Y direction toward a display surface of the display monitor. The angle is illustrated as a, and is shown to be 90°, but the angle may be larger or smaller in other examples. The top bracket portion  102  can also include a mounting arm  126  that is pivotably coupled to the front edge  106  of the main body portion  104 . The mounting arm  126  can include a mounting mechanism, such as threads  146  or a magnet, for coupling to the camera. 
     In an example, the upper rear arm portion  116  is coupled to the rear edge  108  of the main body portion  104 . The upper rear arm portion  116  can be pivotably coupled to the main body portion  104  with a first hinge  128 . The first hinge  128  can allow the main body portion  104  to pivot in the Z direction with respect to the upper rear arm portion  116 . The upper rear arm portion  116  can have a bend from a positive Y direction to a negative Y direction along the negative Z direction. The upper rear arm portion  116  can be substantially rectangular with a same length in the X direction as the main body portion  104 . A length of the upper rear arm portion  116  in the Z direction can be less than a height of the display monitor, but a shorter length may be more advantageous for a better center of gravity of the bracket assembly  100  with a camera coupled to the bracket assembly  100 . With a better center of gravity, a user may more easily be able to adjust the camera without the bracket assembly  100  becoming unstable or falling from the display monitor. 
     The lower rear arm portion  118  is coupled to the upper rear arm portion  116  so that the upper rear arm portion  116  is positioned between the main body portion  104  and the lower rear arm portion  118 . The upper rear arm portion  116  can be pivotably coupled to the lower rear arm portion  118  with a second hinge  130 . The lower rear arm portion  118  can also be rectangular, with a same width in the X direction as the upper rear arm portion  116 . The second hinge  130  can allow the lower rear arm portion  118  to pivot in the Z direction with respect to the upper rear arm portion  116 . The lower rear arm portion  118  can contact a housing rear surface of the display monitor to secure the bracket assembly  100  to the display monitor. 
     The lower rear arm portion  118  can be coupled to and uncoupled from the clip body  120 . The clip body  120  can define a second rearward facing surface  124  facing the lower rear arm portion  118  (e.g., facing the positive Y direction). The clip body  120  can also define a forward facing surface  122  that is opposite the second rearward facing surface  124 . That is, the forward facing surface  122  can face a negative Y direction. A distance in the Y direction between the first rearward facing surface  114  and the forward facing surface  122  can be adjustable to the depth of the display monitor. For example, the distance may be adjustable between 0.25 inches and 3 inches. The clip body  120  may be a sleeve that defines tracks (shown as tracks  448  in  FIG.  4 C ) in which the lower rear arm portion  118  can be positioned within. The lower rear arm portion  118  may slidably couple and snap into the clip body  120 . Left and right surfaces of the lower rear arm portion  118  can slide along the Z direction and snap into the tracks to couple the lower rear arm portion  118  to the clip body  120 . A forward facing surface of the lower rear arm portion  118  can contact the second rearward facing surface  124  of the clip body  120  when the lower rear arm portion  118  is coupled to the clip body  120 . This coupling can limit relative rotational and translational movement of the lower rear arm portion  118  relative to the clip body  120  except for translation in the Z direction. In other examples, the clip body  120  may be a magnet that can magnetically couple to another magnet on the lower rear arm portion  118 , Velcro that can couple to other Velcro on the lower rear arm portion  118 , or a different adhesive mechanism for coupling the clip body  120  to the lower rear arm portion  118 . 
       FIGS.  2 A- 2 C  show perspective views of an example of a camera  232  oriented in a first position with respect to a display surface  242  of a display monitor  234 , according to certain embodiments. The display monitor  234  may include a housing around the display screen and housing display electronics. The housing may define a housing front surface  236 , a housing rear surface  238 , and a housing top surface  240 . The housing front surface  236  may be parallel to the display surface  242  of the display screen and is opposite the housing rear surface  238 . The housing top surface  240  can extend between the housing front surface  236  and the housing rear surface  238 . The camera  232  can be coupled to a bracket assembly  100  at a mounting arm  126  of the bracket assembly  100 . The bracket assembly  100  can be coupled to and supported by the display monitor  234  by the housing top surface  240  contacting a bottom surface  110  of the bracket assembly  100 , the housing front surface  236  contacting a first rearward facing surface  114  of a front tab  112  of the bracket assembly  100 , and the housing rear surface  238  coupled to and contacting a forward facing surface  122  of a clip body  120 . The front tab  112  can limit movement of the bracket assembly  100  in a first horizontal direction perpendicular to the housing front surface  236 . For example, the first rearward facing surface  114  of the front tab  112  can contact the housing front surface  236  in order to limit movement of the bracket assembly  100  in the Y direction. 
     The first position can correspond to a position in which an optical axis of the camera  232  is substantially perpendicular to the display surface  242  of the display monitor  234  in order to capture the subject in front of the display monitor, e.g. a user. In the first position, the center of gravity of the assembly of the camera  232  coupled to the bracket assembly  100  is positioned over the housing top surface  240  of the display monitor  234 . 
       FIGS.  3 A- 3 C  show perspective views of an example of a camera  232  oriented in a second position with respect to a display surface  242  of a display monitor  234 , according to certain embodiments. The mounting arm (e.g., mounting arm  126  in  FIGS.  1 ,  2 A, and  2 B ) can include a hinge  352  allowing the mounting arm  126  to pivot relative to the main body portion  104  allowing the optical axis of the camera  232  to be rotated from being substantially perpendicular to the display surface  242  to being substantially parallel to the display surface  242 . With the optical axis substantially parallel to the display surface  242 , an object, such as a document, on a surface that the display monitor  234  is positioned on, e.g. a desk surface, can be captured by the camera and presented on the display surface  242  and to other users of a videoconference. To transition the camera  232  from the first positon to the second position a user may grasp the camera  232  and pull the camera  232  in the negative Y-direction in order to cause the mounting arm  126  to rotate via the hinge  352  coupling the mounting arm  126  to the main body portion  104  around the X-axis. In the second position, the center of gravity of the camera  232  and the bracket assembly  100  can be positioned in front of a forward edge  354  of the housing top surface  240  of the display monitor  234 . With the clip body  120  coupled to the lower rear arm portion  118 , due to the coupling of the forward facing surface  122  of the clip body  120  to the housing rear surface  238  and the coupling of the clip body  120  to the lower rear arm portion  118 , rotation of a main body portion  104  of the bracket assembly  100  relative to the display monitor  234  due to the forwardly positioned center of gravity is prevented while the mounting arm is pivoted relative to the main body portion  104 . That is, the bottom surface  110  remains in contact with the housing top surface  240  while the mounting arm  126  is pivoted without the need of a user holding the main body portion  104  in place, thus allowing one-handed repositioning of the camera  232  between the first position and the second position. The clip body  120  thus negates a need for a weight, e.g. a metal bar, to be included internally within the upper rear arm portion (e.g., upper rear arm portion  116  in  FIGS.  1 A- 1 B ) or the lower rear arm portion  118  to counter balance the mass of the camera  232 . In some embodiments, a weight may be included in order to have the center of mass positioned more in the Y-direction, for additional support. 
       FIGS.  4 A- 4 C  show perspective views of steps for mounting and unmounting an assembly of a camera and bracket assembly to and from a display monitor, according to certain embodiments. In  FIG.  4 A , an initial configuration of a bracket assembly  100  prior to mounting on a display monitor  234  is shown. A camera  232  is coupled to the bracket assembly  100 . The bracket assembly  100  includes a clip body  120  coupled to a lower rear arm portion  118  of the bracket assembly  100 . 
     In  FIG.  4 B , the bracket assembly  100  is mounted to the display monitor  234 . A forward facing surface  122  of the clip body  120  can be an adhesive surface, such as microsuction tape, to couple to a housing rear surface  238  of the display monitor  234  in a releasable manner. Other portions of the bracket assembly  100 , such as a bottom surface  110 , and a first rearward facing surface  114  may be in contact with the display monitor  234 , wherein only the forward facing surface  122  of the clip body  120  may be coupled to the display monitor  234 . The first rearward facing surface  114  can prevent translation of the bracket assembly  100  in the Y direction. The coupling of the lower rear arm portion  118  to the clip body  120  can restrict all relative rotational and translational movement of the lower rear arm portion  118  relative to the clip body  120  except for translation in a coupling/uncoupling direction. For example, the coupling/uncoupling direction may be in a Z direction, as shown in  FIG.  4 C , so the lower rear arm portion  118  may only be able to move in the Z direction relative to the clip body  120 . 
     In  FIG.  4 C , the bracket assembly  100  is partially unmounted from the display monitor  234 , with the clip body  120  uncoupled from the lower rear arm portion  118  and adhesively coupled to the housing rear surface  238 . The clip body  120  can define two tracks  448  into which edges of the lower rear arm portion  118  can be positioned to couple the lower rear arm portion  118  to the clip body  120 . Additionally, the tracks  448  and the lower rear arm portion  118  can define complimentary detents in the lower rear arm portion  118  to slidably couple and snap in a coupled position relative to the clip body  120 . The clip body  120  can also include path features  144  to further assist with coupling the lower rear arm portion  118  to the clip body  120 . The path features  144  can be extrusions that corresponding indentations of the lower rear arm portion  118  can receive to align the lower rear arm portion  118  appropriately with the clip body  120 . In addition, a bottom lip  450  of the clip body  120  can prevent the lower rear arm portion  118  from sliding downwardly out of the clip body  120 . When the lower rear arm portion  118  is coupled to the clip body  120 , a bottom surface of the lower rear arm portion  118  can contact the bottom lip feature  450 . The lower rear arm portion  118  can be repeatedly coupled and uncoupled from the clip body  120  using the tracks  448 , the path features  144 , and the complimentary detents. As such, a user can determine a desired position for the bracket assembly  100  with the camera  232  mounted and position and coupled the clip body  120  on the housing rear surface  238  such that the bracket assembly  100  remains at the desired position. Each time the clip body  120  is coupled to the lower rear arm portion  118 , the bracket assembly  100  and the camera  232  will be positioned at the preconfigured desired position. 
     In some examples, a mounting system may include a plurality of clip bodies. The plurality of clip bodies may be coupled to multiple second devices, for example multiple display monitors or other computer peripheral devices, and/or in multiple positions on the same second device. The plurality of clip bodies allows a user to preconfigure a plurality of desired positions to be used with a single assembly of a camera and a bracket assembly, wherein the user may uncouple the bracket assembly from a first clip body at a first preconfigured desired position and then coupled the bracket assembly to a second clip body at a second preconfigured desired position. This allows the user to quickly mount a camera without taking time to re-determine the position and aiming at the new placement. For example, the first preconfigured desired position may be on a desktop display monitor and be used for single person web conferences and the second preconfigured desired position may be on a wall mounted display monitor in a conference room and be used for multi person web conferences. This allows camera use to occur in multiple locations without having dedicated cameras in each location. 
     The assembly of the bracket assembly  100  coupled to the camera  232  may be mounted to another display monitor, or at a different position of the display monitor  234 , without the clip body  120 . The bottom surface  110  of the main body portion  104  can be supported on a top surface of the other display monitor. The lower rear arm portion  118  can contact a rear surface of the other display monitor without being coupled to the clip body  120 . As a result, the bracket assembly  100  can be securely coupled to the other display monitor without the clip body  120 , but using the clip body  120  can provide additional support while the camera  232  is transitioned between the first position and the second position, as described in  FIGS.  2 A-C  and  3 A-C.

Indeed, the methods and systems described herein may be embodied in a variety of other forms; furthermore, various omissions, substitutions and changes in the form of the methods and systems described herein may be made without departing from the spirit of the present disclosure. The accompanying claims and their equivalents are intended to cover such forms or modifications as would fall within the scope and spirit of the present disclosure. 
     Although the present disclosure provides certain example embodiments and applications, other embodiments that are apparent to those of ordinary skill in the art, including embodiments which do not provide all of the features and advantages set forth herein, are also within the scope of this disclosure. Accordingly, the scope of the present disclosure is intended to be defined only by reference to the appended claims. 
     Conditional language used herein, such as, among others, “can,” “could,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain examples include, while other examples do not include, certain features, elements, and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more examples or that one or more examples necessarily include logic for deciding, with or without author input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular example. 
     The terms “comprising,” “including,” “having,” and the like are synonymous and are used inclusively, in an open-ended fashion, and do not exclude additional elements, features, acts, operations, and so forth. Also, the term “or” is used in its inclusive sense (and not in its exclusive sense) so that when used, for example, to connect a list of elements, the term “or” means one, some, or all of the elements in the list. The use of “adapted to” or “configured to” herein is meant as open and inclusive language that does not foreclose devices adapted to or configured to perform additional tasks or steps. Additionally, the use of “based on” is meant to be open and inclusive, in that a process, step, or other action “based on” one or more recited conditions or values may, in practice, be based on additional conditions or values beyond those recited.
