     Those skilled in the art will appreciate and understand that, according to common practice, various features of the drawings discussed below are not necessarily drawn to scale, and that dimensions of various features and elements of the drawings may be expanded or reduced to more clearly illustrate the embodiments of the present invention described herein. 
     DETAILED DESCRIPTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims. 
     In the following detailed description, references are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific embodiments in accordance with the described embodiments. Although these embodiments are described in sufficient detail to enable one skilled in the art to practice the described embodiments, it is understood that these examples are not limiting such that other embodiments may be used, and changes may be made without departing from the spirit and scope of the described embodiments. 
     The following disclosure relates to an accessory device suitable for use with an electronic device. The accessory device may define a protective cover or case for the electronic device. In some instances, the accessory device may include a first part designed to couple with a second part, with the first part and the second part combining to enclose the electronic device. Further, in order to assist a user in determining proper installment between the two parts, the accessory device may include several features. For example, the accessory device may include a detection mechanism, or sensor, designed to detect whether the electronic device is present in the accessory device. The sensor may include an electrical contact designed to electrically couple with an electrical contact of the electronic device, thereby allowing direct communication between the accessory device and the electronic device. In this manner, using the detection mechanism, the accessory device may communicate to the electronic device that the electronic device is present in the accessory device. 
     Further, at least one of the parts (of the accessory device) may include several additional detection mechanisms designed to determine whether the two parts are properly aligned with one another by detecting the presence of certain structural components. For example, the first part may include several tabs, or extensions, each of which being designed to mate with a receptacle in the second part. Each receptacle (or at least one of the receptacles) may include a sensor positioned proximate to the receptacle to detect whether a tab is positioned in its respective receptacle. Each sensor may provide an input to the accessory device, or a processor circuit of the accessory device, and based on the inputs, the accessory device (or the processor circuit) may communicate to the electronic device whether the accessory device is properly installed. Accordingly, the communication may include an indication that each sensor detects its respective tab in a receptacle. Alternatively, when the accessory device does not include a processor circuit, each sensor may provide an input, as an electrical signal, to the electronic device to indicate whether the sensor detects a tab in its respective receptacle. Accordingly, in either event, the electronic device can receive information whether the accessory device is properly installed with the electronic device. Also, in some embodiments, the communication is provided through electrical contacts and embedded flexible circuits throughout the accessory device. In other embodiments, the accessory device and the electronic device may establish wireless communication by, for example, Bluetooth, near field communication (“NFC”), and/or 802.11 (Wi-Fi) protocol, to provide the indication whether the accessory device is properly installed. 
     Also, the electronic device may use the indication to display a message on a display of the electronic device. The message may indicate to a user whether the accessory device is properly installed on the electronic device. For instance, the message may include a statement that the accessory device is properly assembled/installed, thereby providing a confirmation to the user that the accessory device needs no further action. Alternatively, the message may include a statement that the accessory device is not properly installed/assembled, and may further suggest a corrective action to the user, with the corrective action including instructions to correct the issue and properly install the accessory device with the electronic device. 
     The accessory device may also include a latch mechanism designed to lock the first part together with the second part. The user may actuate the latch mechanism to place the accessory device in a locked configuration or an unlocked configuration. The locked configuration holds the first and second parts together, while the unlocked configuration allows the first and second parts to separate to remove the electronic device. The accessory device may include a sensor positioned proximate to the latch mechanism to determine the position of the latch mechanism. For example, the sensor may detect whether the latch mechanism is in the locked and/or unlocked configuration, and provide an input to the accessory device that triggers communication to the electronic device of the locked or unlocked configuration. The electronic device may use the communication to generate and display a message (on the display) indicating whether the accessory device is locked or unlocked, and may further suggest a corrective action to lock the latch mechanism when the accessory device is unlocked. 
     In order to provide additional protection to the electronic device, the accessory device may include a sealing element formed from a compressible material, such as silicone. When the accessory device encloses the electronic device, the sealing element may engage the electronic device, and in particular, a protective layer (such as a transparent cover glass that overlays the display) of the electronic device. Further, the sealing element may engage and compress against the electronic device to provide an ingress barrier as well as protection against shock when, for example, the electronic device is dropped. Also, the sealing element may be disposed in the first part that is designed to cover a front portion of the electronic device associated with the display and the protective layer. In some instances, the first part includes an opening (free of any transparent layer) to allow direct access to the protective layer and the display. In this regard, when the display includes a capacitive touch sensitive layer, the first part allows the user to access and interact with the display, by capacitive means, while the sealing element protects against ingress entering through an interface between the sealing element and the protective layer. 
     Also, in some embodiments, the electronic device includes a force detection sensor, or force detection layer, designed to sense an amount of force applied to the display. Further, the force detection sensor may also detect an amount of force applied by the aforementioned sealing element to the protective layer. For example, when the first part is assembled with the second part and the sealing element is positioned between the first part and the protective layer, the electronic device may determine whether the sealing element is properly aligned and engaged with the protective layer based upon the force detected by the force detection sensor at the protective layer. The electronic device may compare the detected amount of force with a predetermined amount of force, and generate and present a message on the display indicating whether the sealing element is properly aligned and/or engaged with the electronic device, and in particular, the protective layer. It should be noted that proper alignment/engagement is associated with the detected amount of force being within a tolerance of the predetermined amount of force, or within a predetermined range of force. The message may include a statement that the sealing element is properly aligned with the protective layer, thereby providing a confirmation to the user that the accessory device needs no further action. Alternatively, the message may include a statement that the sealing element is not properly aligned with the protective layer, and may further suggest a corrective action to the user, which may include instructions to place the sealing element in proper alignment. 
     These and other embodiments are discussed below with reference to  FIGS. 1-10 . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these Figures is for explanatory purposes only and should not be construed as limiting. 
       FIG. 1  illustrates an isometric view of an embodiment of an electronic device  100 . In some embodiments, the electronic device  100  is a tablet device. In the embodiment shown in  FIG. 1 , the electronic device  100  is a mobile communication device, such as a smartphone. The electronic device  100  may include an enclosure  102  designed to enclose several operational components, including integrated circuits, a speaker, a microphone, as non-limiting examples. In some embodiments, the enclosure  102  is formed from a metal, such as aluminum or an aluminum alloy. The electronic device  100  may further include a display  104  designed to display visual information. The display  104  may include a touch-sensitive layer (not shown) integrated with the display  104  such that the display  104  can receive and respond to a touch input by a user. Further, the touch-sensitive layer may include a capacitive touch sensitive layer that receives and responds to a capacitive coupling with the capacitive touch sensitive layer. The electronic device  100  may also include an outer protective layer  106  overlaying the display  104 . The outer protective layer  106  may include a transparent material, such as glass or sapphire, that covers the display  104 . 
     Also, the electronic device  100  may further include a button  108  designed to receive an additional input, allowing a user to provide a control to the electronic device  100 . The button  108  may be used to control, for example, a software application or “app” visually presented on the display  104 . The electronic device  100  may include an internal power source (not shown) used to provide electrical current to several operational components of the electronic device  100 . Accordingly, the electronic device  100  may include a charging port  110  designed to receive power in order to provide power to the internal power source and/or the internal components. Also, although not shown, the electronic device  100  may include one or more control inputs (such as button) positioned along various locations around the enclosure  102 , with the control inputs offering different control features for the electronic device  100 . 
     Also, the electronic device  100  may include a force detection layer  112  (shown as a dotted line) disposed below the outer protective layer  106 , and designed to detect a force or pressure applied to the outer protective layer  106  and/or the display  104 . Further, the force detection layer  112  may detect an amount of force or pressure applied to the outer protective layer  106  and/or the display  104 . The electronic device  100  may include a processor circuit (not shown) designed to receive an input from the force detection layer  112  indicating an amount of force received at the outer protective layer  106  and/or the display  104 . This will be further discussed below. 
       FIG. 2  illustrates a plan view of the electronic device  100  shown in  FIG. 1 , showing the electronic device  100  disposed in an embodiment of an accessory device  200 , in accordance with the described embodiments. The accessory device  200  generally covers an outer perimeter of the electronic device  100 , such as the enclosure  102  (shown and labeled in  FIG. 1 ). Further, as shown in  FIG. 2 , the accessory device  200  may cover a portion of the outer protective layer  106 . Further, in some embodiments, the accessory device  200  includes a sealing element  202  positioned between the accessory device  200  and the outer protective layer  106 . Also, the sealing element  202  is designed and positioned to engage the outer protective layer  106 . In some embodiments, the sealing element  202  includes a compressible material, such as silicone or including liquid silicone rubber. Also, when the electronic device  100  is disposed in the accessory device  200  (as shown in  FIG. 2 ), the sealing element  202  may compress based in part on a force (or forces) provided by the accessory device  200  and the outer protective layer  106 . This allows the sealing element  202  to firmly engage the outer protective layer  106  and provide a sealing barrier against ingress attempting to enter an interface between the sealing element  202  and the outer protective layer  106 . Accordingly, the sealing element  202  may prevent ingress of contaminants from entering the electronic device  100 . This will be shown and described below. 
       FIG. 3  illustrates an exploded view of the accessory device  200  shown in  FIG. 2 , showing various features designed to interact with the electronic device  100  or with other features of the accessory device  200 . The accessory device  200  may include several parts that secure together to define a body that provides a protective enclosure for the electronic device  100 . For example, the accessory device  200  may include a first part  204  and a second part  206  designed to mechanically couple with the first part  204 . In some embodiments, the first part  204  and the second part  206  are formed from a rigid polymer material, such as plastic. Further, the first part  204  may couple with the second part  206  such that the sealing element  202  is positioned between the first part  204  and the outer protective layer  106 . Also, although not shown, the first part  204  and/or the second part  206  may include an outer cover formed from a material such as silicone or leather. Generally, the outer cover may include any material designed to enhance an appearance of the accessory device  200 . 
     The accessory device  200  may include a surface  212  designed to receive the electronic device  100 . The surface  212  may include an electrical contact  210  designed to electrically couple with an electrical contact (not shown) of the electronic device  100  when the electronic device  100  is positioned on the surface  212 . The electrical contact  210  may be positioned anywhere on the surface  212  such that the electrical contact  210  is in a location corresponding to the electrical contact of the electronic device  100 . The electrical contact  210  may allow the accessory device  200  to communicate with the electronic device to, for example, provide an indication (in the form of an electronic signal or signals) to the electronic device  100  whether the electronic device  100  is positioned on the surface  212 , and in particular, whether the electronic device  100  is properly aligned with the second part  206 . A “proper alignment” of an electronic device with the second part refers to the electronic device  100  resting on the surface  212  and within sidewalls  214  extending around the surface  212 . The electrical contact  210  may allow the accessory device  200  to provide other forms of communication with the electronic device  100 , and will be discussed below. Alternatively, the communication may pass via wireless communication between the accessory device  200  and the electronic device  100 , with the wireless communication taking the form of Bluetooth, near field communication (“NFC”), and/or 802.11 (Wi-Fi) protocol. 
     Further, when the electronic device  100  is positioned on the surface  212 , the electrical contact  210  may generate an input to a processor circuit  216  disposed in the second part  206  below the surface  212 . The processor circuit  216  may run a program (or programs) stored on a memory circuit  218  also disposed in the second part  206  below the surface  212 . A battery  220  disposed in the second part  206 , and below the surface  212 , may provide power to the processor circuit  216  and the memory circuit  218 . If the electronic device  100  is properly aligned, the processor circuit  216  may use the input from the electrical contact  210 , and based on the input, generate an output to the electronic device  100  to communicate to the proper alignment to the electronic device  100 . Conversely, if the electronic device  100  is not properly aligned, corresponding to an “error,” the accessory device  200  may provide a different output to the electronic device  100  indicating the improper alignment. In either event, the electronic device  100  may generate a message, based upon the output from the processor circuit  216 , that is presented on the display  104 , indicating to a user whether the electronic device  100  is properly aligned. For example, when the electronic device  100  is not properly installed, the message may indicate the improper alignment and further suggest a corrective action to the user to place the electronic device  100  in proper alignment. 
     Also, the indication from the accessory device  200  may include an indication whether the electronic device  100  is compatible with the accessory device  200 . For example, the accessory device  200  may include a size and shape for a particular electronic device (in terms of design and/or model), and when the particular electronic device is not detected, the accessory device  200  may communicate this information to the electronic device  100 , causing the electronic device  100  to provide a message on the display  104  that the electronic device  100  is incompatible with the accessory device  200 . 
     The first part  204  may include several features designed to couple with the second part  206 . For example, the first part  204  may include a first sidewall  222  having several extensions, or tabs, such as a first extension  224 , a second extension  226 , and a third extension  228  along the first sidewall  222 . Also, as shown, the first part  204  includes a second sidewall  232  opposite the first sidewall  222  that also include several extensions. The second part  206  may include several receptacles designed to receive the extensions. For example, the second part  206  may include a first receptacle  244 , a second receptacle  246 , and a third receptacle  248  designed to receive the first extension  224 , the second extension  226 , and the third extension  228 , respectively, when the first part  204  is coupled with the second part  206 . Also, the second part  206  may further include additional receptacles (not labeled) designed to receive a corresponding number of extensions (shown as dotted lines) positioned along the second sidewall  232 . Although a discrete number of extensions in particular locations of the first part  204  are shown, a different number of extensions may be disposed along any of the sidewalls of the first part  204 . Accordingly, the second part  206  may include a corresponding number of receptacles in corresponding locations. Although not shown, one or more additional mechanical features may be used to couple the first part  204  with the second part  206 . 
     The accessory device  200  may include features designed to determine whether the first part  204  is secured with the second part  206 . For example, as shown in the enlarged view, the second part  206  may include a fourth receptacle  254  having a detection mechanism  256 . The detection mechanism  256  may detect the presence of an extension in the first part  204 , such as a fourth extension  234 . Based upon the detection, the detection mechanism  256  may provide an input to indicate the fourth extension  234  is positioned within the fourth receptacle  254 . The processor circuit  216  may receive the input (in the form of an electrical signal) from the detection mechanism  256  via an electrical coupling (not shown). 
     In some embodiments, the detection mechanism  256  is a mechanical switch that is driven or actuated in response to the fourth extension  234  mechanically coupling with the detection mechanism  256 , causing the detection mechanism  256  to close an electrical circuit (not shown) and generate an electrical signal to the processor circuit  216  indicating the fourth extension  234  is in the fourth receptacle  254 . In other embodiments, the detection mechanism  256  includes a solid-state proximity sensor, such as a capacitive sensor designed to detect a change in capacitance at a surface of the capacitive sensor, with the change in capacitance indicating the fourth extension  234  is in the fourth receptacle  254 . The detection mechanism  256  may include an alternative solid-state proximity sensor, such as a photoelectric sensor that emits light (which may be infrared) and detects the light reflected from the fourth extension  234 , indicating the fourth extension  234  is in the fourth receptacle  254 . Still, in other embodiments, the detection mechanism  256  includes a Hall Effect sensor designed to detect an external magnetic field. In this regard, the fourth extension  234  may include a magnet (not shown) capable of producing the external magnetic field detected by the detection mechanism  256  when the fourth extension  234  is disposed in the fourth receptacle  254 . It should be noted that any described receptacle may include a detection mechanism similar to the detection mechanism  256  to carry out a similar function as that of the detection mechanism  256 . 
     Each detection mechanism may electrically couple with, and provide an input to, the processor circuit  216 , which may use the inputs to provide an indication to the electronic device  100  whether the first part  204  is aligned with respect to the second part  206 . The first part  204  may be “properly aligned” with the second part  206  when each extension of the first part  204  is positioned in a receptacle of the second part  206 , and detected by an aforementioned detection mechanism. Accordingly, if any one of the detection mechanisms does not detect an extension in a receptacle, the processor circuit  216  may generate an output to the electronic device  100  indicating the first part  204  is not properly aligned with the second part  206 . The output may be in the form of an electrical signal or wireless communication. 
     A detection mechanism herein may communicate with the processor circuit  216  by different means. For example, the detection mechanism may include a “normally closed” circuit such that the detection mechanism is in communication (including electrical communication) with the processor circuit  216  until the detection mechanism detects the extension. Accordingly, the termination of communication indicates the extension is present in the receptacle. Alternatively, the detection mechanism may include a “normally open” circuit such that the detection mechanism is not in communication with the processor circuit  216  until the detection mechanism detects the extension. Accordingly, the presence of communication between the detection mechanism and the processor circuit indicates the extension is present in the receptacle. The processor circuit  216  may be configured for either type of circuit, such that an “error” corresponds to logic indicating that the extension is not detected in the receptacle by the detection mechanism. Also, the processor circuit  216  may be configured to receive and process multiple inputs, including an input from each detection mechanism of the second part  206 . 
     When the processor circuit  216  determines the first part  204  is not properly aligned with the second part  206 , the processor circuit  216  may generate an output to the electronic device  100  indicating to the electronic device  100  that the first part  204  is not properly aligned with respect to the second part  206 . The means for passing the message or indication from the accessory device  200  (or the processor circuit  216 ) to the electronic device  100  may include any means previously described for communication between the accessory device  200  and the electronic device  100 . This may cause the electronic device  100  to generate a message, based upon the message or indication from the accessory device  200 , presented on the display  104  of the electronic device  100 , indicating to a user that the first part  204  is not properly aligned with respect to the second part  206 . The message may further suggest a corrective action to the user. 
       FIG. 4  illustrates an isometric view of a rear portion of the accessory device  200 , showing a latch mechanism  302  designed to lock the first part  204  with the second part  206 , or unlock the first part  204  from the second part  206 . A locked configuration of the accessory device  200  may refer to the latch mechanism  302  maintaining an engagement between the first part  204  and the second part  206 . In this regard, the first part  204  and the second part  206  may include one or more locking components (not shown) that couple with one another in the locked configuration, and are controllable by movement of the latch mechanism  302 . An unlocked configuration of the accessory device  200  may refer to the latch mechanism  302  allowing the first part  204  to disengage from the second part  206 , or vice versa. In this regard, the aforementioned locking components may decouple from one another based on movement of the latch mechanism  302 . 
     A rotation of the latch mechanism  302  may cause a locking and unlocking between the first part  204  and the second part  206 . In this regard, the latch mechanism  302  may include a recessed portion  304  designed to receive an object or tool (not shown) used to rotationally drive the latch mechanism  302  bi-directionally, denoted by the two-sided arrow  306 . The recessed portion  304  includes a shape that may receive a tool, such as a Philips screwdriver. However, the recessed portion  304  may include various sizes and shapes, some of which may correspond to a size and a shape of another object or tool. Also, in some embodiments, the latch mechanism  302  is positioned near a corner of the second part  206 . However, in the embodiment shown in  FIG. 4 , the latch mechanism  302  is located in a central region, or approximately the central region, of the second part  206 . 
     The accessory device  200  may further include a detection mechanism  312  positioned proximate to the latch mechanism  302 , and designed to determine a configuration of the latch mechanism  302 , such as the locked configuration and/or the unlocked configuration. In this regard, the latch mechanism  302  may include a target  314  identified by the detection mechanism  312  when the target  314  is within sufficient proximity to the detection mechanism  312 , thereby indicating the latch mechanism  302  is in the locked configuration. For example, as shown in  FIG. 4 , the target  314  is positioned the detection mechanism  312  can detect the target  314 . The detection mechanism  312  may be electrically coupled with the processor circuit  216  (shown in  FIG. 3 ) to provide communication to the processor circuit  216  information related to the locked and/or the unlocked configuration. 
     In some embodiments, the detection mechanism  312  is a mechanical switch designed to open or close based upon a mechanical coupling between the latch mechanism  302  and the detection mechanism  312 . In other embodiments, the detection mechanism  312  includes a proximity sensor, such as a capacitive or photoelectrical sensor, designed to provide an input to the processor circuit  216  based on a detection of the target  314 , with the input corresponding to a locked configuration, as an example. In the embodiment shown in  FIG. 4 , the latch mechanism  302  includes an inductive proximity sensor designed to detect a metal. In this regard, the target  314  may include a metal detectable by the detection mechanism  312  when the target  314  is within sufficient proximity to the detection mechanism  312 . This may occur by rotating the latch mechanism  302  to position the target  314  within sufficient proximity to the detection mechanism  312 . The detection of the target  314  by the detection mechanism  312  may correspond to a locked configuration. Still, in other embodiments, the latch mechanism  302  includes an encoder having a rotary disc. In this regard, the detection mechanism  312  may be positioned below the latch mechanism  302 , and configured to detect light from a light source passing through an opening (or openings) of the rotary disc. As the latch mechanism  302  turns, the detection mechanism  312  detects the light passing through the opening (or openings) in a predetermined manner that corresponds to a locked configuration, as an example. In the foregoing embodiments, the detection mechanism  312  may provide an indication of the locked configuration (when, for example, the target  314  is detected) as well as the unlocked configuration. Alternatively, the detection mechanism  312  may provide an indication only when the target  314  is detected, corresponding to the locked configuration. 
     The detection mechanism  312  may be configured to provide an input to the processor circuit  216  (in the form of an electrical signal) when the latch mechanism  302  is in the locked or unlocked configuration. In either configuration, the processor circuit  216  may provide an output to the electronic device  100  (shown in  FIG. 3 ), indicating the configuration the latch mechanism. The means for passing the message or indication from the accessory device  200  (or the processor circuit  216 ) to the electronic device  100  may include any means previously described for communication between the accessory device  200  and the electronic device  100 . Based upon the output from the accessory device  200 , the electronic device  100  may generate and present a message on the display  104  (shown in  FIG. 1 ), indicating to a user that the latch mechanism  302  is in the locked or unlocked position. The message may further suggest a corrective action to the user if the latch mechanism  302  is in the unlocked configuration. 
     The detection mechanisms shown and described in  FIGS. 3 and 4  may be designed to monitor conditions according to a predetermined time interval. For example, the detection mechanism  312  may monitor the latch mechanism  302  every 20 seconds. Further, the predetermined time interval may be set by the user in order to conserve battery power in the accessory device  200 , as less monitoring may result in less battery power consumption. Alternatively, the detection mechanisms may monitor conditions in real-time in order to provide any changes to the conditions immediately. This may allow the user to be notified as soon as an undesired situation occurs, such as the detection mechanism  256  no longer detecting the fourth extension  234  (shown in  FIG. 3 ). The real-time monitor function may be incorporated according to a user setting. 
       FIG. 5  illustrates a cross sectional view of the accessory device  200  carrying the electronic device  100 , further showing the sealing element  202  engaging the outer protective layer  106 . For purposes of simplicity, the display  104  (shown in  FIG. 1 ) is removed. The sealing element  202  may be positioned between the accessory device  200  and the electronic device  100 , and in particular, between the first part  204  and the outer protective layer  106 . In this regard, by securing together the first part  204  with the second part  206 , the sealing element  202  is compressed against between the outer protective layer  106  and the first part  204 . Further, as shown in the enlarged view, the sealing element  202  may change its size and shape in response to compression forces from the first part  204  and the outer protective layer  106 , and elastically deform to the contour of the outer protective layer  106 . This may create an ingress barrier at an interface between the sealing element  202  and the outer protective layer  106  to prevent ingress into the electronic device  100 . 
     Further, the sealing element  202  may provide a counterforce to the outer protective layer  106 . The electronic device  100  may be designed detect the counterforce from the sealing element  202 . For example, the force detection layer  112  may detect a force applied to the outer protective layer  106  from the sealing element  202 . A processor circuit (not shown) of the electronic device  100  may receive an input from the force detection layer  112  (in the form of an electrical signal), with the input corresponding to an amount of detected force from the sealing element  202  to the outer protective layer  106 . The amount of detected force may be compared with a predetermined amount of force, or a predetermined range of force, consistent with a force known to compress the sealing element  202  without causing damage to the electronic device  100 . Further, when the amount of detected force within an acceptable tolerance of the predetermined amount of force, or within the predetermined range of force, the electronic device  100  determines the accessory device  200  is properly installed with the electronic device  100 . Also, the electronic device  100  may monitor (continuously or at intervals) the force received from the accessory device  200  (and in particular, from the sealing element  202 ) to determine whether the force is within the tolerance or within the predetermined range. If any location of the outer protective layer does not receive a force within the tolerance or within the predetermined range, the electronic device  100  may provide an indication to a user that the accessory device  200  is not properly installed. The indication may include a message presented on the display (not shown), and may further provide a corrective action to the user. In this manner, the accessory device  200  may offer an ingress barrier monitored in real-time by the electronic device  100 . 
       FIG. 6  illustrates an isometric view of a rear portion of the accessory device  200 , showing the latch mechanism  302  in an unlocked configuration. As shown in the enlarged view, the target  314  of the latch mechanism  302  is positioned such that the detection mechanism  312  cannot identify the target  314 . Accordingly, the detection mechanism  312  may provide an input (in the form of an electrical signal) to the processor circuit  216  (shown in  FIG. 3 ) or to the electronic device, indicating the unlocked configuration. Alternatively, the detection mechanism  312  may provide no indication until the target  314  is identified. 
     When the latch mechanism  302  is in the unlocked configuration, the electronic device  100  may present a message on the display  104  (shown in  FIG. 1 ). For example,  FIG. 7  illustrates a plan view of the electronic device  100  positioned in the accessory device  200 , showing the display  104  presenting a message  402  based upon a configuration of the accessory device  200 , in accordance with the described embodiments. As shown, the message  402  presented on the display  104  indicates the latch mechanism  302  (shown in  FIG. 6 ) is in the unlocked configuration. The message  402  may change according to the various conditions previously described. For example, the message  402  may indicate a misalignment between the electronic device  100  and the accessory device  200 , a misalignment between parts of the accessory device, and/or a lack of pressure to the outer protective layer. Further, in some embodiments, the message  402  may include a corrective action. Regarding the latter, as shown in  FIG. 7 , the message  402  may describe a corrective action associated with the unlocked position of the latch mechanism  302 , which may include a notification to the user to turn the latch mechanism  302  to place the latch mechanism  302  in the locked position. Also, the message  402  may indicate the accessory device  200  is properly installed with the electronic device  100 , providing confirmation to the user that the accessory device  200  is properly configured. 
       FIGS. 8 and 9  illustrate alternative embodiments of an accessory device. However, although not described, the embodiments shown in  FIGS. 8 and 9  may include any feature or features previously described for an accessory device.  FIG. 8  illustrates a plan view of an alternative embodiment of an accessory device  500 , showing the accessory device  500  partitioned in an alternate manner. For example, the accessory device  500  may include a first part  504  and a second part  506  divided laterally, with the first part  504  designed to fit over an uppermost region of an electronic device (not shown), and the second part  506  designed to fit over a lowermost region (or region other than the uppermost region) of the electronic device. This configuration may allow for an accessory device  500  to include a reduced interface region, defined by the partition, between the first part  504  and the second part  506 , resulting in a reduced location or region through which ingress can pass through the accessory device  500 . 
       FIG. 9  illustrates a cross sectional view of an alternative embodiment of an accessory device  600 , with the accessory device  600  having a hinge assembly  602 . The hinge assembly  602  may allow a first part  604  to pivot or rotate with respect to a second part  606 , or vice versa. For example, the hinge assembly  602  may allow the first part  604  to rotate away from the second part  606  in order to receive or remove an electronic device (not shown) from the accessory device  600 . In some embodiments, the second part  606  may include a hook  608  to receive a cavity  610  located in the first part  604 . The hook  608  may be spring-loaded, or otherwise designed to actuate in response to engaging the first part  604  to receive first part  604  at the cavity  610 . This may allow for an accessory device  600  to include a single attached body that reduces the likelihood losing the first part  604  and/or the second part  606 . 
       FIG. 10  illustrates a flowchart  700  showing a method for forming an accessory device suitable as a protective cover for an electronic device, in accordance with the described embodiments. In step  702 , a first part and a second part are formed. The first part and the second part can combine with one another part to provide the protective cover. In some embodiments, the first part includes an extension. Further in some embodiments, the second part includes a receptacle to receive the extension. 
     In step  704 , a detection mechanism is provided. The detection mechanism is configured to detect a coupling between the first part and the second part and communicate the coupling to the electronic device. In some embodiments, the detection mechanism provides an input to a processor circuit in the accessory device. The input may correspond to the detection mechanism not detecting the extension in the receptacle. In this manner, the accessory device may communicate to the electronic device that the first part is not properly aligned with respect to the second part, corresponding to a misalignment between the first part and the second part. The means for passing the indication from the accessory device (or the processor circuit) to the electronic device may include a direct communication by an electrical coupling between the accessory device and the electronic device, or a wireless communication. Based upon the output from the accessory device, the electronic device may generate and present a message that is presented on a display of the electronic device, indicating to a user that the first part is not properly aligned with the second part. The message may further suggest a corrective action to the user.
