     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 electronic device, such as a mobile communication device that takes the form of a smartphone or a tablet computer device. The electronic device may include several enhancements and modifications not found in traditional electronic devices. For example, the electronic device may include a protective cover (formed from a transparent material) and a display assembly coupled with the protective cover. The electronic device may further include a border positioned between the protective cover and the display assembly. The border may include uniform dimensions (such as a uniform border width) designed to uniformly cover an outer edge (or outer peripheral region) of the display assembly. In this manner, when the display assembly illuminates to present visual information (textual, still images, or motion images, i.e., video), the display assembly illuminates at least to the edges of the border, thereby providing the electronic device with an “edge-to-edge” appearance, as the visual information can be seen at the edges of the border. 
     The electronic device may further include a vision system used for object recognition, including facial recognition. A bracket assembly may hold the vision system in the electronic device. Rather than fixing the bracket assembly with an enclosure, or housing, of the electronic device, the bracket assembly can move relative to the enclosure, and can be subsequently aligned during an assembly operation of the protective cover to the enclosure. In this regard, the protective cover may include an alignment module used to align the vision system. The alignment module may engage, or contact, the vision system, causing both the vision system and the bracket assembly to move (relative to the enclosure) in order to align the vision system in a desired manner. This allows for a dynamic alignment of the vision system with fewer tolerance issues, as a rigid alignment of the bracket assembly (by, for example, screws, fasteners, clips, etc.) is not required. 
     The vision system may include operational components such as a camera module, a light emitting module, and a light receiving module (which may include an additional camera module). The bracket assembly is designed to maintain a fixed spacing, or distance, between the camera module, the light emitting module, and the light receiving module. When placed in the bracket assembly and subsequently into the enclosure, the vision system may undergo a calibration operation in order to adjust, or correct, any deviations (relative to a predetermined standard) of the camera module, the light emitting module, and/or the light receiving module. Once the calibration is complete, the fixed spacing, or distance, between the camera module, the light emitting module, and the light receiving module are maintained by the bracket assembly. Moreover, should the electronic device receive a force sufficient to cause movement of the bracket assembly, each of the operational components of the vision system may undergo a corresponding movement, as the bracket assembly maintains the fixed spacing between the operational components. For example, if the bracket assembly moves or shifts by a millimeter (“mm”) relative to the enclosure, then the camera module, the light emitting module, and the light receiving module each move 1 mm, in the same direction as the bracket assembly, such that the respective spacing the camera module, the light emitting module, and the light receiving module is maintained. 
     The electronic device may further include a circuit board assembly designed to occupy less space in the electronic device. For example, the circuit board assembly may be divided into a first circuit board stacked over a second circuit board. A stacked configuration of multiple circuit boards (one stacked over the other) may reduce the footprint of the circuit board assembly in two dimensions. Also, the aforementioned circuit boards may include operational components (such as integrated circuits or processor circuits) positioned on multiple, opposing surfaces such that some operational components on one circuit board are facing other operations components on the other circuit board. Also, the circuit board assembly may include several interposers, or interconnects, designed to carry signals between the first and second circuit boards, such that the first and second circuit boards (as well as their respective operational components) are in communication with one another. 
     The electronic device may further include a dual camera assembly. The dual camera assembly may include a first camera module and a second camera module. A light emitter (such as a strobe light) may be positioned between the first camera module and the second camera module. While the light emitter is designed to enhance the overall image quality captured by the first camera module and/or the second camera module, the light emitter should be isolated from the first camera module and the second camera module such that light from the light emitter does not “leak,” or extend to, the first camera module and/or the second camera module and expose the camera modules to additional unwanted light. This promotes the first camera module and the second camera module receiving indirect (or reflected) light from the light emitter, as opposed to direct light. In order to isolate the light emitter, the dual camera assembly may include a trim structure formed from an opaque material, such as steel (including stainless steel). The trim structure may include multiple walls and chambers designed to i) receive the first camera module, the second camera module, and the light emitter, and ii) isolate the first camera module and the second camera module from directly obtaining light from the light emitter. 
     The electronic device may further include a battery assembly that includes multiple battery components. For example, the battery assembly may include a first battery component coupled to a second battery component, with each of the first battery component and the second battery component designed to generate energy for operational components (such as integrated circuits carried by the circuit board assembly, the vision system, and/or the dual camera assembly, as non-limiting examples). 
     The electronic device may further include wireless power receiving module designed to receive an induced current by magnetic flux (from an alternating electromagnetic field) and use the induced current to provide energy to charge the battery assembly. The wireless power receiving module may include a receiver coil that receives the induced alternating current, which can be converted to a direct current. The wireless power receiving module may provide a simplified method for charging the battery assembly, whereby exposure to the magnetic flux, rather than plugging a connector (of a cable assembly) into the electronic device, is sufficient to charge the battery assembly. 
     These and other embodiments are discussed below with reference to  FIGS.  1 - 32   . 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 a front isometric view of an embodiment of an electronic device  100 , in accordance with some described embodiments. In some embodiments, the electronic device  100  is a tablet computer device. In the embodiment shown in  FIG.  1   , the electronic device  100  is a mobile wireless communication device, such as a smartphone, as a non-limiting example. The electronic device  100  may include a band  102  that extends and defines an outer perimeter of the electronic device  100 . The band  102  may include a metal, such as aluminum, stainless steel, or an alloy that includes at least one of aluminum or stainless steel. The band  102  may be composed of several sidewall components, such as a first sidewall component  104 , a second sidewall component  106 , a third sidewall component  108  (opposite the first sidewall component  104 ), and a fourth sidewall component (not labeled in  FIG.  1   ). The aforementioned sidewall components may include any material(s) previously described for the band  102 . 
     In some instances, some of the sidewall components form part of an antenna assembly (not shown in  FIG.  1   ). As a result, a non-metal material, or materials, may separate the sidewall components of the band  102  from each other in order to electrically isolate the sidewall components. For example, a first composite material  112  separates the first sidewall component  104  from the second sidewall component  106 , and a second composite material  114  separates the second sidewall component  106  from the third sidewall component  108 . The aforementioned composite material may include an electrically inert, or insulating, material(s), such as plastics and/or resin, as non-limiting examples. 
     The electronic device  100  may further include a display assembly  116  (shown as a dotted line) that is covered by a protective cover  118 . The protective cover  118  may be referred to a transparent protective cover, as the protective cover  118  may include a material such as glass, plastic, sapphire, or the like. In this regard, the protective cover  118  may be referred to as a transparent cover, a transparent protective cover, or a cover glass (when the protective cover  118  includes glass). The display assembly  116  may include multiple layers (discussed below), with each layer providing a unique function. The display assembly  116  may be partially covered by a border  120  that extends along an outer edge of the protective cover  118  and partially covers an outer edge of the display assembly  116 . The border  120  can be positioned to hide or obscure electrical and mechanical connections between the layers of the display assembly  116  and flexible circuit connectors to the display assembly  116 . This will be shown below. Also, the border  120  to may include uniform thickness. For example, the border  120  may include a thickness that generally does not change in the X- and Y-dimensions. This will be further discussed below. Also, the border  120  may include an opaque material, such as ink or other pigmented material, adhered to the protective cover  118 . The adhering means may include an adhesive mixed with the ink (or other pigment material), or an adhesive layer between the protective cover  118  and the border  120 . Also, the protective cover  118  may cover the border  120  such that the protective cover  118  is elevated with respect to the border  120  in the Z-dimension (of a Cartesian coordinate system). 
     Also, as shown in  FIG.  1   , the display assembly  116  may include a notch  122 , representing an absence of the display assembly  116 . The notch  122  may allow for a vision system (discussed below) that provides the electronic device  100  with information for object recognition, such as facial recognition. The electronic device  100  may include a masking layer (not labeled in  FIG.  1   ) designed to hide or obscure the vision system, while openings of the masking layer allow the vision system to receive the object recognition information. This will be further discussed below. As shown in  FIG.  1   , the protective cover  118  includes an opening  124 , which may represent a single opening of the protective cover  118 . The opening  124  may allow for transmission of acoustical energy (in the form of audible sound) out of the electronic device  100 , which may be generated by an audio module (not shown in  FIG.  1   ) of the electronic device  100 . Further, the opening  124  may allow for transmission of acoustical energy (in the form of audible sound) into the electronic device  100 , which may be received by a microphone (not shown in  FIG.  1   ) of the electronic device  100 . Also, as shown in  FIG.  1   , the electronic device  100  may not include a button, such as a “home button,” commonly found in electronic devices, as the protective cover  118  does not include additional openings. 
     The electronic device  100  may further include a port  126  designed to receive a connector (not shown in  FIG.  1   ) of a cable assembly. The port  126  allows the electronic device  100  to send and receive data information to and from another device (not shown in  FIG.  1   ), and also allows the electronic device  100  to receive electrical energy to charge a battery assembly (not shown in  FIG.  1   ). Accordingly, the port  126  may include terminals (not shown in  FIG.  1   ) that electrically couple to the connector. 
     Also, the electronic device  100  may include several openings in the sidewall components. For example, the electronic device  100  may include openings  128  that allow an additional audio module (not shown in  FIG.  1   ) of the electronic device  100  to emit acoustical energy out of the electronic device  100 . The electronic device  100  may further include openings  132  that allow an additional microphone (not shown in  FIG.  1   ) of the electronic device to receive acoustical energy. Also, the electronic device  100  may include a first fastener  134  and a second fastener  136  designed to secure with a rail (not shown in  FIG.  1   ) that is coupled to the protective cover  118 . In this regard, the first fastener  134  and the second fastener  136  are designed to couple the protective cover  118  with the band  102 . 
     The electronic device  100  may include several control inputs designed to provide a command to the electronic device  100 . For example, the electronic device  100  may include a first control input  142  and a second control input  144 . The aforementioned control inputs may be used to adjust the visual information presented on the display assembly  116  and/or the volume of acoustical energy output by an audio module, as non-limiting examples. The control inputs may include one of a switch or a button designed to generate a command to a processor circuit (not shown in  FIG.  1   ). The control inputs may at least partially extend through openings in the sidewall components. For example, the second sidewall component  106  may include an opening  146  that receives the first control input  142 . 
       FIG.  2    illustrates a rear isometric view of the electronic device  100  shown in  FIG.  1   . In addition to the aforementioned sidewall components, the band  102  may further include a fourth sidewall component  110 . As shown, a third composite material  152  separates the first sidewall component  104  from the fourth sidewall component  110 , and a fourth composite material  154  separates the fourth sidewall component  110  from the third sidewall component  108 . 
     The electronic device  100  may further include a protective cover  158  that couples with the band  102 . In this regard, the protective cover  158  may combine with the band  102  to form an enclosure of the electronic device  100 , with the enclosure (band  102  and protective cover  158 ) defining an internal volume that carries several components, such as a battery assembly, circuit board assembly, and vision system, as non-limiting examples. The protective cover  158  may include any material(s) previously described for the protective cover  118  (shown in  FIG.  1   ). When the protective cover  158  includes a non-metal material, the electronic device  100  may provide hardware (and software) to support wireless charging. For example, the electronic device  100  may include a wireless power receiving module  160  (represented by a dotted line) covered by the protective cover  158  and positioned in the internal volume. The wireless power receiving module  160  is designed to receive an induced current when exposed to magnetic flux from an alternating electromagnetic field that is external to the electronic device  100 . This will be further discussed below. Also, the protective cover  118  (shown in  FIG.  1   ) may be referred to as a “front protective cover” or “first protective cover,” as the front of the electronic device  100  is generally associated with the display assembly  116  (which is covered by the protective cover  118 ). Also, the protective cover  158  may be referred to as a “rear protective cover,” “second protective cover,” or “bottom wall,” as the back of the electronic device  100  is generally associated with a rear wall. 
     The electronic device  100  may further include a camera assembly  170 , which may include a dual camera assembly. As shown, the camera assembly  170  may include a first camera module  172 , a second camera module  174 , and a light emitter  176  positioned between the first camera module  172  and the second camera module  174 . The light emitter  176 , also referred to as a camera flash module, is designed to provide additional lighting during an image capture event by the first camera module  172  and/or the second camera module  174 . However, it is desired to prevent some of the light “leakage” from the light emitter  176  into the first camera module  172  and the second camera module  174 . In this regard, the camera assembly  170  may further include a trim element (not shown in  FIG.  1   ) designed to isolate the light emitter  176  from the first camera module  172  and the second camera module  174  such that the first camera module  172  and the second camera module  174  do not directly receive light from the light emitter  176 . In this manner, the first camera module  172  and the second camera module  174  may only receive desired light from the light emitter  176 , such as light reflected from an object, the image of which is captured by the first camera module  172  and/or the second camera module  174 . The trim element will be further shown and described below. Also, the camera assembly  170  may further include a protective cover  178  formed from a transparent material that covers at least the first camera module  172  and the second camera module  174 . However, the protective cover  178  may include a masking layer (not shown in  FIG.  2   ) designed to at least partially obscure part of the first camera module  172  and the second camera module  174 . Further, the protective cover  178  may include an opening (not labeled) for the light emitter  176 . It should be noted, however, that the masking layer includes openings that allow the first camera module  172  and the second camera module  174  to capture images, and that allow the light emitter  176  to emit light that exits the electronic device  100 . Also, as shown in  FIG.  2   , the first camera module  172  and the second camera module  174  are aligned (collectively) in a manner that is parallel with respect to the second sidewall component  106  (shown in  FIG.  1   ) and the fourth sidewall component  110 . In other words, an imaginary line can be drawn through the first camera module  172  and the second camera module  174  that is parallel with respect the second sidewall component  106  (shown in  FIG.  1   ) and the fourth sidewall component  110 . 
       FIG.  3    illustrates a plan view of the electronic device  100  shown in  FIG.  1   , showing the display assembly  116  illuminated to present visual information  180 . The visual information  180  may take the form of textual information, still images, video images, or some combination thereof. As shown, the visual information  180  may extend at least to the border  120 . This is due in part to the border  120  covering an outer edge of the display assembly  116 , as shown in the enlarged view. Also, as shown in the enlarged view, an outer edge of the border  120  may extend to an outer edge of the protective cover  118 . The border  120  may cover an outer perimeter of the display assembly  116 , with the exception of the notch  122  formed in the display assembly  116 . 
       FIG.  4    illustrates a cross sectional view of the electronic device  100 , taken along line A-A in  FIG.  3   . As shown, the display assembly  116  may include a touch sensitive layer  202 , a display layer  204 , and a force sensitive layer  206 . The display assembly  116  may be secured with the protective cover  118  by an adhesive  208 . Also, although not shown, the display assembly  116  may include adhesive layers to adhesively secure the touch sensitive layer  202  with the display layer  204 , and to adhesively secure the display layer  204  with the force sensitive layer  206 . 
     The touch sensitive layer  202  is designed to receive a touch input when, for example, a user (not shown in  FIG.  4   ) depresses the protective cover  118 . The touch sensitive layer  202  may include capacitive touch-sensitive technology. For example, the touch sensitive layer  202  may include a layer of capacitive material that holds an electrical charge. The layer of capacitive material is designed to form a part of multiple capacitive parallel plates throughout a location corresponding to the display layer  204 . In this regard, when a user touches the protective cover  118 , the user forms one or more capacitors. Moreover, the user causes a voltage drop across one or more of the capacitors, which in turns causes the electrical charge of the capacitive material to change at a specific point (or points) of contact corresponding to a location of the user&#39;s touch input. The capacitance change and/or voltage drop can be measured by a processor circuit (not shown in  FIG.  4   ) of the electronic device  100  to determine the location of the touch input. The touch input can be relayed from the touch sensitive layer  202  to a circuit board assembly (shown and described later) by a flexible circuit  212  electrically and mechanically coupled with the touch sensitive layer  202  by a connector  222 . As shown, the flexible circuit  212  may bend or curve around the display layer  204  and the force sensitive layer  206  to electrically and mechanically couple with touch sensitive layer  202 . 
     In some embodiments, the display layer  204  includes a liquid crystal display (“LCD”) that relies upon backlighting to present the visual information. In the embodiment shown in  FIG.  4   , the display layer  204  includes an organic light emitting diode (“OLED”) display designed to illuminate individual pixels, when needed. Also, the display layer  204  may include a connector  224  used to electrically and mechanically couple the display layer  204  with a flexible circuit  214  that electrically couples with a circuit board assembly (shown later), with flexible circuit  214  placing the display layer  204  in communication with the circuit board assembly. Also, in some embodiments, the display layer  204  may include an active matrix organic light emitting diode (“AMOLED”) display. 
     As shown, the border  120  may secure with the protective cover  118 . Also, based on the position of the border  120 , the border may hide or obscure the connector  222  and the connector  224 . Accordingly, the border  120  may hide or obscure a connection between the flexible circuit  212  and the connector  222 , as well as a connection between the flexible circuit  214  and the connector  224 . Further, the border  120  may be minimized (while maintaining its uniform thickness in the Y-dimension) to cover the connections while also minimally hiding or obscuring the display assembly  116 , and in particular, the display layer  204 . 
     The force sensitive layer  206  may operate by determining an amount of force or pressure applied to at least one of the protective cover  118 , the touch sensitive layer  202 , and/or the display layer  204 . In this regard, the force sensitive layer  206  may distinguish between different amounts of force applied to the electronic device  100 . The different amounts of force may correspond to different user inputs. The force sensitive layer  206  may include multiple parallel capacitor plate arrangements, with one plate of each capacitor plate arrangement having an electrical charge. When a force to the protective cover  118  causes the distance between one or more pairs of parallel plate capacitor to reduce, a change in capacitance between one or more pairs of parallel plate capacitors may occur. The amount of change in capacitance corresponds to an amount of force exerted on the protective cover  118 . Also, although not shown, the force sensitive layer  206  may include a connector that is used to connect with a flexible circuit to place the force sensitive layer  206  in communication with a circuit board assembly. 
     Further, in order to support the protective cover  118  and facilitate assembly of the protective cover  118  with the band  102 , the electronic device  100  may include a frame  230  that receives and secures with the protective cover  118  by an adhesive layer (shown, not labeled). Accordingly, the frame  230  may include an opening with a size and shape in accordance with that of the protective cover  118 . The frame  230  may be positioned at least partially between the protective cover  118  and the band  102 . The frame  230  may be formed from a polymeric material, such as plastic. The frame  230  may include a supporting element  232  partially embedded in the frame  230 . In some embodiments, the supporting element  232  includes a ring formed from a metal material that continuously extends around the display assembly  116  in accordance with the frame  230 . However, the supporting element  232  may also be discontinuous, and accordingly, may be selectively embedded in the frame  230 . As shown, the supporting element  232  may extend along the frame  230  to support the display assembly  116  and the protective cover  118 . Also, the flexible circuit  212  may adhesively secure with the supporting element  232  by an adhesive layer (labeled, not labeled). 
     Although the electronic device  100  may lack a dedicated input (such as a home button), the electronic device  100  may nonetheless include virtual inputs presented on the display assembly  116 . For example,  FIG.  5    illustrates a partial plan view of the electronic device shown in  FIG.  3   , further showing a user  250  interacting with the display assembly  116  to alter the visual information  180 , in accordance with some described embodiments. As shown, when the user  250  interacts with the display assembly  116 , the touch sensitive layer  202  (shown in  FIG.  4   ) of the display assembly  116  may determine the interaction, including a location of the interaction. The interaction may cause the visual information  180  to present a virtual button  260 . The virtual button  260  may remain on the display assembly  116 , and may act as a specific input designed to “close,” or remove, at least some of the visual information  180  that was previously presented, and subsequently present a “home screen,” as a non-limiting example. The home screen, as presented by the visual information  180  (when updated), may be associated with a main screen, or starting screen, that presents specific applications (not shown), or software applications, selectable by the user  250 . 
       FIG.  6    illustrates a partial plan view of the electronic device shown in  FIG.  3   , further showing the user  250  interacting with the display assembly  116  to further alter the visual information  180 , in accordance with some described embodiments. As shown, the user  250  may interact with the display assembly  116  using a gesture (such as a swipe, indicated by the arrow). The display assembly  116  may detect the gesture (using one of the aforementioned layers of the display assembly  116 ), which in turn causes the visual information  180  to present application information  270 . The application information  270  may be associated with a software application in use by the user  250 , such as a media player application. The application information  270  may quickly and easily allow the user  250  to alter the software application by, for example, adjusting the song or video being played as well as the volume at which the song or video is played. It should be noted that the application information  270  is not limited to a music player application, and several other types of information may be presented on the display assembly  116 . 
       FIG.  7    illustrates a plan view of the electronic device  100  shown in  FIG.  1   , with the display assembly and the protective cover removed, showing the layout of several components in the internal volume  300 . For purposes of simplicity and illustration, electrical connections, such as flexible circuit, wires, cables, etc., between components are removed. As shown, the electronic device  100  may include a vision system  410  and a bracket assembly  440  used to carry the vision system  410 . The vision system  410  may provide with the electronic device  100  with information related to object recognition, including facial recognition. The bracket assembly  440  is designed to structurally support components of the vision system  410  and maintain a fixed distance between the optical components of the vision system  410 . The features of the vision system  410  and the bracket assembly  440  will be further discussed below. 
     The electronic device  100  may further include a chassis  306  that provides structural support. The chassis  306  may include a rigid material, such as a metal. Also, the chassis  306  may be coupled to the band  102 . In this manner, the chassis  306  may also provide an electrical grounding path for components electrically coupled to the chassis  306 . Also, the chassis  306  may include a wall  308 . The wall  308  may combine with the band  102  to surround the first camera module  172 , the second camera module  174 , and the light emitter  176  of the camera assembly  170 . The wall  308  may also limit or prevent light generated from the light emitter  176  from further entering the internal volume  300 . 
     The electronic device  100  may further include a battery assembly  310  that includes a first battery component  312  coupled with a second battery component  314  by coupling member  316 . The coupling member  316  may include an adhesive material. Both the first battery component  312  and the second battery component  314  are designed to generate electrical energy that can be used by several aforementioned components in the internal volume  300 . Also, as shown in  FIG.  7   , the battery assembly  310  resembles an L-shape, based upon the combined shape of the first battery component  312  and the second battery component  314 . 
     The shape of the battery assembly  310  may accommodate other components in the internal volume  300 . For example, the electronic device  100  may further include a circuit board assembly  320 . The circuit board assembly  320  may include at least two circuit boards in a stacked configuration. The stacked configuration may conserve space in the internal volume  300 , particularly in least one of the X- and Y-dimensions, as well as a Z-dimension (perpendicular to an X-Y plane). The circuit board assembly  320  may include several active components (such as integrated circuits) that provide the primary processing for the electronic device  100 . Also, similar to the battery assembly  310 , the circuit board assembly  320  may resemble an L-shape. In this manner, both the battery assembly  310  and the circuit board assembly  320  can be shaped to conserve space in the internal volume  300 . 
     The electronic device  100  may further include a dock  322  in a location corresponding to the port  126  (shown in  FIG.  1   ). The dock  322  may include terminals and other electrical connection points (not shown in  FIG.  7   ). The dock  322 , in conjunction with the port  126 , can receive a connector (used with a cable assembly), thereby allowing the electronic device  100  to send and receive data. Also, the dock  322  can receive electrical energy used to recharge the battery assembly  310 . 
     The electronic device  100  may further include a wireless power receiving module  160  designed to provide electrical energy to the battery assembly  310 . The wireless power receiving module  160  may include a receiver coil (not shown in  FIG.  7   ) designed to receive an induced current by magnetic flux an alternating electromagnetic field generated by a transmitter coil (not shown) that is external with respect to the electronic device  100 . Also, the chassis  306  may include an opening  336  (defined by a void in the chassis  306 ) such that the chassis  306  does not impede the magnetic flux. Also, the wireless power receiving module  160  may include a shielding element  338  that is positioned between the wireless power receiving module  160  and components in order to shield at least some of the components in the internal volume  300  from the magnetic flux. 
     The electronic device  100  may further include an audio module  342  designed to generate acoustical energy in the form of audible sound. The electronic device  100  may further include a microphone  344  designed to receive acoustical energy. Also, the electronic device  100  may further include several rail clips designed to receive rails secured to the protective cover  118  (shown in  FIG.  1   ). For example, the electronic device  100  may include a first rail clip  352 , a second rail clip  354 , a third rail clip  356 , a fourth rail clip  358 , and a fifth rail clip  362 . The rails clips are designed to couple with the aforementioned rails. This will be shown below. 
       FIG.  8    illustrates a front isometric view of an embodiment of a system  400  that includes a vision system  410 , or vision subsystem, and a bracket assembly  440  designed to carry the vision system  410 , in accordance with some described embodiments. As shown, the vision system  410  may include several operational components (including optical components), with each operational component providing a specific function. For example, the vision system  410  may include a first camera module  412 , a light emitting module  414 , and a second camera module  416 . The first camera module  412 , or first operational component, is designed to capture an image of an object (not shown). The light emitting module  414 , or second operational component, is designed to emit light, in the form of multiple light rays, in a direction toward the object. Accordingly, the light emitting module  414  may be referred to as a light emitter. In some instances, the light emitting module  414  emits light that is not visible by the human eye. For example, the light emitting module  414  may emit IR light. The second camera module  416 , or third operational component, is designed to receive at least some of the light rays that are emitted from the light emitting module  414 , subsequent to the light rays reflecting from the object. Accordingly, the second camera module  416  may be referred to as a light receiver. Also, the second camera module  416  may include a filter designed to filter out other types of light outside the frequency range of the light rays emitted from the light emitting module  414 . As an example, the filter (located within the second camera module  416  or over a lens of the second camera module  416 ) may block light other than IR light, and permit IR light into the second camera module  416 . 
     The vision system  410  is designed to assist in object recognition. In this regard, the vision system  410  may use the first camera module  412  to generate a two-dimensional image of the object. In order to determine spatial relationships between various features of the object, the light rays emitted from the light emitting module  414  may project a dot pattern onto the object (or objects). When the light generated from the light emitting module  414  is reflected from the object, the second camera module  416  captures at least some of the reflected light to create an image of the projected dot pattern on the object. The projected dot pattern can be used to form a depth map of the object, with the depth map corresponding to a three-dimensional counterpart of the object. The combination of the image (taken by the first camera module  412 ) and the dot pattern (taken by the second camera module  416 ) projected onto the image can be used to develop a three-dimensional profile of the object. In this regard, when the vision system  410  is in an electronic device (not shown), the vision system  410  can assist the electronic device in providing a facial recognition of a user&#39;s face. This will be further discussed below. 
     The bracket assembly  440  may include a first bracket  442  coupled to a second bracket  444 . The coupling may include welding, adhering, fastening, clipping, or the like. The first bracket  442  and the second bracket  444  may include a rigid material, such as steel or aluminum. However, other materials, such as plastic (including a molded plastic), are possible. In order for the vision system  410  to provide accurate object recognition, the space or distance between the modules should remain constant, or at least substantially constant. In other words, any relative movement of a module of the vision system  410  with respect to the remaining modules should be prevented or substantially limited. The bracket assembly  440  is designed to provide a rigid system that houses the modules and also prevents relative movement of any module with respect to the remaining modules. Further, when the vision system  410  and the bracket assembly  440  are positioned in an electronic device, external forces exerted on the electronic device (such as a drop of the electronic device against a structure) may cause the vision system  410  and the bracket assembly  440  to move or shift in the electronic device. However, any movement of bracket assembly  440  may correspond to an equal amount of movement of each of the modules of the vision system  410  such that relative movement of the modules of the vision system  410  is prevented. Moreover, in some instances, the bracket assembly  440  is not held or affixed to an enclosure of the electronic device by fasteners, adhesives, clips, or other rigid fixture-type structures. This will be further discussed below. 
     Each of the modules of the vision system  410  may include a flexible circuit, or flex connector, designed to electrically couple a module to a circuit board (not shown in  FIG.  8   ) to place the vision system  410  in electrical communication with one or more processor circuits (not shown in  FIG.  8   ) positioned on the circuit board. For example, the first camera module  412 , the light emitting module  414 , and the second camera module  416  may include a first flexible circuit  422 , a second flexible circuit  424 , and a third flexible circuit  426 , respectively, with each of the flexible circuits extending from their respective modules and out of bracket assembly  440 . Also, as shown, the first flexible circuit  422  may overlap the second flexible circuit  424  in order to align the flexible circuits in a desired manner. 
     Optionally, the bracket assembly  440  may define a platform or space designed to receive components of an electronic device, some of which may be used with the vision system  410 . For example, the platform, defined by the bracket assembly  440 , may carry a first component  472 , a second component  474 , a third component  476 , a fourth component  478 , and a fifth component  482 . The first component  472  may include a light emitter designed to provide additional light (including additional IR light) while the vision system  410  is in use. The second component  474  may include an audio module designed to generate acoustical energy in the form of audible sound. The third component  476  may include a microphone designed to receive acoustical energy. The fourth component  478  may include a light sensor, including an ambient light sensor, designed to detect an amount light incident on an electronic device (such as the electronic device  100 , shown in  FIG.  1   ). The light sensor may be used to trigger use of the first component  472  when the first component  472  includes a light emitter, based upon a determined amount of light by the light sensor. The fifth component  482  may include a proximity sensor designed to determine an approximate distance between a user and the electronic device. The proximity sensor may be used to provide an input used to turn off a display assembly (such as the display assembly, shown in  FIG.  1   ) when a relatively low-light condition is determined, and may also be used to provide an input used to turn on the display assembly when a relatively high light condition is determined. The relatively low and high light conditions may be relatively to a predetermined or threshold light condition. Accordingly,  FIG.  8    shows that the bracket assembly  440  may not only carry components of the vision system  410 , but also may provide a space for additional components. 
       FIG.  9    illustrates a rear isometric view of the vision system and the bracket assembly shown in  FIG.  8   . As shown, the second bracket  444  may include spring elements, such as a first spring element  446  and a second spring element  448 , extending from a surface of the second bracket  444 . When the bracket assembly  440  is positioned in an electronic device (not shown in  FIG.  9   ), the spring elements may engage an enclosure of the electronic device (or a chassis, such as the chassis  306  shown in  FIG.  7   ) and support the bracket assembly  440  and the modules of the vision system  410  (labeled in  FIG.  8   ). Further, the spring elements may act as biasing elements that bias the bracket assembly  440  in a direction away from the enclosure. For instance, when a protective cover (such as the protective cover  118 , shown in  FIG.  1   ) is secured to the enclosure, the protective cover and/or the enclosure may apply compression forces on the bracket assembly  440 , causing bending or flexing of the first spring element  446  and the second spring element  448 . However, the first spring element  446  and the second spring element  448  are designed to provide a counterforce that biases the bracket assembly  440  toward the protective cover or against an alignment module (discussed later), thereby providing an enhanced securing force for the bracket assembly  440  (and the vision system  410 ). This will be further shown below. Also, a cutting operation use to cut the second bracket  444  to form the first spring element  446  and the second spring element  448  may cut only a portion of the second bracket  444  such that the second bracket  444  does not include through holes, or openings, in locations corresponding to the first spring element  446  and the second spring element  448 . As a result, the second bracket  444  provides a continuous, uninterrupted support surface for the modules. 
     In order to electrically couple the modules to a circuit board, the flexible circuits may include connectors. For example, the first flexible circuit  422 , the second flexible circuit  424 , and the third flexible circuit  426  may include a first connector  432 , a second connector  434 , and a third connector  436 , respectively. Also, the second bracket  444  may include a through hole  452 , or opening, in a location corresponding to the light emitting module  414  (shown in  FIG.  8   ). This allows for a heat sinking element (not shown) to pass through the through hole  452  and thermally couple to the light emitting module  414 , such that the heat sinking element dissipates heat from the light emitting module  414  and prevents the light emitting module  414  from overheating during use. 
       FIGS.  8  and  9    show the first bracket  442  and the second bracket  444  combine to receive and secure the first camera module  412 , the light emitting module  414 , and the second camera module  416 . In this regard, the aforementioned modules may enhance or increase the overall rigidity of the bracket assembly  440 . For example, the modules may occupy space or voids between the first bracket  442  and the second bracket  444 , while also engaging the first bracket  442  and/or the second bracket  444 . Accordingly, the modules may prevent the bracket assembly  440  from unwanted twisting or bending. 
     Also, when the vision system  410  is secured in the bracket assembly  440 , the bracket assembly  440  is designed to ensure the modules of the vision system  410  maintain a fixed distance apart from one another. For example, the bracket assembly  440  is designed to maintain a fixed, predetermined distance, between the first camera module  412  and the second camera module  416 . Also, the bracket assembly  440  is designed to maintain a fixed, predetermined distance between the light emitting module  414  and the second camera module  416 . Further, the bracket assembly  440  is designed to maintain a fixed, predetermined distance between the first camera module  412  and the light emitting module  414 . In this regard, the vision system  410  can be calibrated once the modules are assembled in the bracket assembly  440 , with the calibration accounting for the fixed distances between the modules, and the bracket assembly  440  eliminates the need to re-calibrate the vision system  410  as the modules maintain their respective fixed distances. By maintaining these fixed distances, the bracket assembly  440  ensures proper and accurate information related to objection recognition capabilities by the vision system  410 . 
       FIG.  10    illustrates an exploded view of the protective cover  118  and the display assembly  116 , as well as several additional components of the electronic device  100  (shown in  FIG.  1   ). As shown, the protective cover  118  is surrounded by, and engaging, the frame  230 . The frame  230  may include several rails designed to secure the protective cover  118  with an enclosure (not shown in  FIG.  10   ). The frame  230  may include a first rail  552 , a second rail  554 , a third rail  556 , a fourth rail  558 , and a fifth rail  562  designed to couple with the first rail clip  352 , the second rail clip  354 , the third rail clip  356 , the fourth rail clip  358 , and the fifth rail clip  362 , respectively, shown in  FIG.  7   . Also, the frame  230  may further include a sixth rail  564  designed to receive the first fastener  134  and the second fastener  136  (shown in  FIG.  1   ). 
     The border  120  may secure with a surface, such as an internal surface, of the protective cover  118 . The border  120  may include a uniform dimension  568  (such as a uniform width) in the X-dimension the Y-dimension. Accordingly, the border  120 , may include a dimension (such as a “border width”) of equal dimensions at any location in the X- and Y-dimensions. In addition to the border  120  hiding or obscuring electrical and mechanical connections to the display assembly  116 , additional layers may be used to hide or obscure some features. For example, an electronic device described herein may include a masking layer  570  designed to at least partially hide or obscure the vision system  410  and the bracket assembly  440  (shown in  FIGS.  7 - 9   ). The masking layer  570  may include an opaque material designed to block light, including visible light, UV light, and IR light. The opaque material may include an ink material that is adhered to a surface, such as an internal surface, of the protective cover  118 . Also, the masking layer  570  may include an appearance, in terms of color and reflectivity, designed to match that of the border  120 . For example, when the border  120  includes a black or white appearance (as non-limiting examples), the masking layer  570  may include a black or white appearance, respectively. Also, the uniform dimension  568  of the border  120  may extend to locations adjacent to (or in contact with) the masking layer  570 . 
     In order to allow the vision system  410  to provide object recognition, the masking layer  570  may include several openings (not labeled). However, at least some of the openings may be covered or filled by a material that is semi-opaque. For example, an electronic device described herein may include a layer  572  that covers an opening of the masking layer  570 , a layer  574  that covers an additional opening of the masking layer  570 , and a layer  576  that covers an additional opening of the masking layer  570 . In some embodiments, the layer  572 , the layer  574 , and the layer  576  include an appearance, in terms of color and/or reflectivity, similar to that of the masking layer  570  (and accordingly, an appearance, in terms of color and/or reflectivity, similar to that of the border  120 ). However, the layer  572 , the layer  574 , and the layer  576  may be designed to filter out light in some frequencies while selectively passing light in other frequencies. For example, the layer  572 , the layer  574 , and the layer  576  may block visible light (as well as other light), and pass IR light. As a result, the layer  572 , the layer  574 , and the layer  576  may be referred to as visible light filters. The layer  572 , the layer  574 , and the layer  576  may cover components of the vision system  410  (shown in  FIGS.  8  and  9   ) designed to transmit/emit IR light (such as the light emitting module  414  in  FIG.  8   ) or receive IR light (such as the second camera module  416  in  FIG.  8   ). A light module  624  (described below) may also be aligned with a visible light filter. 
     Further, an electronic device described herein may include a layer  578  and a layer  582 , each of which covers an additional opening of the masking layer  570 . In some embodiments, the layer  578  and the layer  582  include an appearance, in terms of color and/or reflectivity, similar to that of the masking layer  570  (and accordingly, an appearance, in terms of color and/or reflectivity, similar to that of the border  120 ). However, the layer  578  and the layer  582  may be designed to filter out some light in some frequencies while selectively passing light in other frequencies. For example, the layer  578  and the layer  582  may block IR light (as well as other light), and pass visible light. As a result, the layer  578  and the layer  582  may be referred to as IR light filters. The layer  578  and the layer  582  may cover components of the vision system  410  (shown in  FIGS.  8  and  9   ) designed to receive visible light (such as the first camera module  412  in  FIG.  8   ). An ambient light sensor  626  (described below) may also be aligned with an IR light filter. 
     In some instances, the bracket assembly  440  and the vision system  410  (shown in  FIGS.  7 - 9   ) are not affixed in the electronic device  100  (shown in  FIG.  1   ). Rather, the bracket assembly  440  (along with the vision system  410 ) may be placed in the internal volume  300  (shown in FIG.  7 ) and may to generally move freely with respect to, for example, the chassis  306  and the band  102  (shown in  FIG.  7   ). However, as the protective cover  118  is coupled with the band  102  (by way of the rails securing with the rail clips), the position of the bracket assembly  440  and the vision system  410  can be adjusted to a desired location in the internal volume  300 , and compressive forces can retain the bracket assembly  440  and the vision system  410  in a desired location. 
     In this regard, an electronic device described herein may include an alignment module  610  that is coupled with the protective cover  118 . In some instances, the masking layer  570  and the light filter layers described above are positioned between the protective cover  118  and the alignment module  610 . The alignment module  610  may couple with the protective cover  118  in a location such when the protective cover  118  is assembled with the enclosure (or with the remaining portion of an electronic device), the alignment module  610  guides the modules of the vision system  410  (shown in  FIG.  8   ) such that the modules align with a desired light filter described above. This will be further shown and discussed below. 
     An electronic device described herein may further include an audio module  622  designed to generate acoustical energy. The audio module  622  may be seated on the alignment module  610  such that the audio module  622  is aligned with the opening  124  of the protective cover  118 . An electronic device described herein may further include a light module  624  designed to generate light, such as IR light. The light module  624  may be used in conjunction with the vision system  410  (shown in  FIG.  8   ). For example, the light module  624  may provide additional IR light under conditions of relatively low light. The alignment module  610  may align the light module  624 . An electronic device described herein may further include an ambient light sensor  626  designed to detect an amount of light external with respect to the electronic device. In some instances, the ambient light sensor  626  provides light conditions (such as low-light conditions) that can be used to activate the light module  624 . The alignment module  610  may include a rail  628  that engages and aligns the ambient light sensor  626 . Also, an electronic device described herein may further include a microphone  632  designed to receive acoustical energy. The microphone  632  may be at least partially aligned with the opening  124  of the protective cover  118 . Also, an electronic device described herein may further include a proximity sensor  634  designed to determine an approximate distance between a user and the electronic device. 
     The notch  122  (in the display assembly  116 ) is designed and positioned to accommodate the alignment module  610 , as well as the vision system  410  (shown in  FIG.  8   ). Also, the chassis  306  may be positioned below the display assembly  116  (in the Z-dimension). Accordingly, the chassis  306  may provide support to the display assembly  116  as well as other components. Also, the border  120  may uniformly cover an outer edge of the display assembly  116  in the X- and Y-dimensions, based upon the uniform dimension  568 . In other words, in a plane (X-Y plane, for example) parallel to a plane defined by the display assembly  116 , the border  120  may uniformly cover the display assembly  116 . 
       FIGS.  11 - 16    show and describe an exemplary assembly operation in which the alignment module  610  is used to align the vision system  410  in a desired location.  FIG.  11    illustrates a side view of the electronic device  100 , showing the protective cover  118 , the alignment module  610 , and the display assembly  116  (shown as a dotted line) prior to assembling with the enclosure, in accordance with some described embodiments. The enclosure may include a combination of the band  102  and the protective cover  158 . As shown, the vision system  410  and the bracket assembly  440  are positioned in the internal volume  300 . Also, the alignment module  610  is secured to the protective cover  118 . As shown in  FIG.  11   , the protective cover  118  may be parallel, or at least substantially parallel, with respect to the band  102 . However, the assembly process may include positioning the protective cover  118  at some non-zero angle with respect to the band  102  such that the protective cover  118  is not parallel with respect to the band  102 . 
       FIG.  12    illustrates a cross sectional view that partially shows the electronic device  100  shown in  FIG.  11   , showing the vision system  410  and the bracket assembly  440  positioned in the enclosure. The electronic device  100  may include a flexible circuit  650  that is electrically and mechanically coupled to the audio module  622 , the light module  624 , and the microphone  632 . Although not shown in  FIG.  12   , the ambient light sensor  626  and the proximity sensor  634  (both shown in  FIG.  10   ) may electrically and mechanically couple with the flexible circuit  650 . The flexible circuit  650  may electrically and mechanically connected to a circuit board assembly (discussed below), thereby placing the audio module  622 , the light module  624 , the microphone  632 , the ambient light sensor  626 , and the proximity sensor  634  in communication with the circuit board assembly. Also, the alignment module  610  is adhesively secured to the protective cover  118 . The alignment module  610  is aligned with the protective cover  118  such that when the audio module  622  is positioned in an opening (not labeled) of the alignment module  610 , the audio module  622  is aligned with the opening  124  of the protective cover  118 . Further, the microphone  632  may be aligned with a diagonal opening (not labeled) of the alignment module  610 , and at least partially aligned with the opening  124 . Also, as shown, a mesh material  125  may cover the opening  124 . Also, the light module  624  may be positioned in an opening (not labeled) of the alignment module  610 , and in particular, the light module  624  may align with an opening of the masking layer  570 . This will be further discussed below. 
     As shown, the bracket assembly  440  is designed to hold components of a vision system, such as the first camera module  412 , the light emitting module  414 , and the second camera module  416 . Although not labeled, each of the first camera module  412 , the light emitting module  414 , and the second camera module  416  may include a flexible circuit. Also, although not labeled, each of the first camera module  412 , the light emitting module  414 , and the second camera module  416  include an adhesive that secures the modules to the bracket assembly  440 . The adhesive may include an electrically conductive adhesive that electrically couples the modules to the bracket assembly  440 . Also, the bracket assembly  440  may include a third bracket  456  secured to at least one of the first bracket  442  and the second bracket  444 . The third bracket  456  may be referred to as a module carrier that holds the light emitting module  414 . The third bracket  456  may attach to at least one of the first bracket  442  and the second bracket  444  by welding, as an example, thereby electrically coupling the brackets together. Other attachment methods that electrically couple the brackets together are possible. Also, as shown, the first spring element  446  and the second spring element  448  may extend from the second bracket  444  and support the bracket assembly  440  and the vision system  410 . Also, the first spring element  446  and the second spring element  448  engage the chassis  306 . As a result, the vision system  410 , including its modules, may be electrically grounded in part by the chassis  306 . 
     The second bracket  444  may include an opening that allows a heat sinking element  462  to thermally couple with the light emitting module  414 , either by direct contact with the light emitting module  414  or by way of a block (not labeled), as shown in  FIG.  12   . The heat sinking element  462  may include a rolled graphite layer that is thermally coupled to the chassis  306 . Accordingly, the chassis  306  may provide electrical charge dissipation and thermal dissipation properties. Regarding the latter, the chassis  306  may be referred to as a heat sink. 
       FIG.  13    illustrates a side view of the electronic device  100  shown in  FIG.  11   , further showing the protective cover  118  being lowered toward the band  102  such that the alignment module  610  engages the vision system  410 . As shown, the engagement force provided by the alignment module  610  to the vision system  410  may cause the vision system  410  and the bracket assembly  440  (not labeled) to shift within the internal volume  300 . In this regard, the vision system  410  and the bracket assembly  440  may shift relative to other parts, such as the band  102  and the protective cover  158 . 
       FIG.  14    illustrates a cross sectional view that partially shows the electronic device  100  shown in  FIG.  12   , with the alignment module  610  engaging the vision system  410  and providing a force that moves the vision system  410  and the bracket assembly  440 . As shown in Step  1 , the protective cover  118  moves in a direction toward the protective cover  158  in order to secure the protective cover  118  to the band  102  (shown in  FIG.  13   ). As the protective cover  118  is moved toward the protective cover  158 , the alignment module  610  may engage a module of the vision system  410  (labeled in  FIG.  12   ). For example, as shown in  FIG.  14   , the alignment module  610  engages the first camera module  412 . As shown in Step  2 , the force provided by the alignment module  610  engaging the first camera module  412  (by way of the protective cover  118  moving toward the protective cover  158 ) causes the first camera module  412  to shift along the X-axis, which in turn causes the bracket assembly  440  and the remaining modules to shift in the X-axis. The shifting, or movement, of the modules causes the modules to align in the electronic device  100  in a desired manner. This will be shown below. In this manner, the first camera module  412  may be referred to as an alignment feature in that the alignment module  610  uses the first camera module  412  to align all of the modules that are carried by the bracket assembly  440 . However, in some embodiments (not shown), the alignment module  610  engages a different module of the bracket assembly  440 . Also, it should be noted that despite the movement or shifting of the modules, the bracket assembly  440  maintains the spacing between i) the first camera module  412  and the second camera module  416 , ii) light emitting module  414  and the second camera module  416 , and iii) the first camera module  412  and the light emitting module  414 . 
     While Step  2  shows the bracket assembly  440  and the modules being shifted along a particular direction, the bracket assembly  440  and the modules may shift in a different direction based the original position of the bracket assembly  440  and the modules in the electronic device  100 . For example, when the alignment module  610  engages a different location of the first camera module  412  (as opposite the location shown in  FIG.  14   ), the bracket assembly  440  and the modules may shift in the opposite direction along the X-axis in order to align the modules in the electronic device  100 . Further, although not shown, the engagement between the alignment module  610  and the first camera module  412  may provide a force that causes the bracket assembly  440  and the modules to move in a direction perpendicular to the X-Z plane, such as along a “Y-axis” (not labeled) that is into and out of the page. The engagement between the alignment module  610  and the first camera module  412  (or any of the modules of the vision system  410 ) may provide a force that causes the bracket assembly  440  and the modules to move in two directions, such as along the X-axis as well as a direction perpendicular to the X-Z plane. Accordingly, in order to properly align the modules, the alignment module  610  may provide a force that moves the modules along two different axes. 
       FIG.  15    illustrates aside view of the electronic device  100  shown in  FIG.  13   , showing an assembled configuration of the electronic device  100 . As shown, the protective cover  118  is coupled with the band  102 , and the rails (labeled in  FIG.  10   ) engage with and secure to their respective rail clips (shown in  FIG.  7   ). 
       FIG.  16    illustrates a cross sectional view that partially shows the electronic device  100  shown in  FIG.  14   , further showing the modules of vision system  410  (labeled in  FIG.  12   ) aligned in the electronic device  100 . The modules of the vision system  410  are aligned in the electronic device  100  subsequent to the alignment module  610  causing the modules of the vision system  410  and the bracket assembly  440  to shift along at least one axis. Further, when the modules of the vision system  410  are aligned in the electronic device  100 , the modules of the vision system  410  are aligned with their respective light filter. For example, the first camera module  412  is aligned with the layer  578  disposed in an opening (not labeled) of the masking layer  570 . The term “aligned” refers to the layer  578  being positioned over the first camera module  412  such that the masking layer  570  does not block the line of view for the first camera module  412 . The layer  578 , as previously described, is capable of passing visible light while blocking other forms of light (such as IR light). Also, although not shown in  FIG.  16   , the ambient light sensor  626  (shown in  FIG.  10   ) is aligned with the layer  582  disposed in an opening (not labeled) of the masking layer  570 . The layer  582 , as previously described, is capable of passing visible light while blocking other forms of light (such as IR light). 
     Also, the light emitting module  414  is aligned with the layer  572  disposed in an opening (not labeled) of the masking layer  570 , and the second camera module  416  is aligned with the layer  574  disposed in an opening (not labeled) of the masking layer  570 . The layer  572  and the layer  574 , as previously described, are capable of passing IR light while blocking other forms of light (such as visible light). Also, the light module  624 , when positioned in the alignment module  610 , is aligned with the layer  576  disposed in an opening (not labeled) of the masking layer  570 . The layer  576 , as previously described, is capable of transmitting IR light while blocking other forms of light (such as visible light). As a result, the masking layer  570  may substantially hide or obscure the modules of the vision system  410  as well as the bracket assembly  440 , while the openings of masking layer  570  are filled with layers designed to transmit certain frequencies of light and block others, thereby allowing the components of the vision system  410  to properly transmit/emit or receive light. 
     Also, the first spring element  446  and the second spring element  448  may flex in response to compression forces from the protective cover  118  and the chassis  306  (or a combination of the protective cover  158  and the chassis  306 ). However, the first spring element  446  and the second spring element  448  may provide a biasing force, or counterforce, in a direction of an arrow  490 . The biasing force may increase the engagement force between the bracket assembly  440  and the alignment module  610 . As a result, the bracket assembly  440  may be held in place without the direct use of fasteners, adhesives, clips, etc., that would permanently fasten the bracket assembly  440  to any structural component of the electronic device  100 . Furthermore, although an external force or load force exerted on the electronic device  100  may cause relative movement of the bracket assembly  440 , the bracket assembly  440  can maintain a constant separation distance between the first camera module  412 , the light emitting module  414 , and the second camera module  416 . This ensures the components of the vision system  410  remain at a fixed and predetermined distance from each other, and the vision system  410  can continue to function properly to obtain object recognition information without a re-calibration operation. Accordingly, any movement of the bracket assembly  440  may correspond to an equal amount of movement of the first camera module  412 , the light emitting module  414 , and the second camera module  416  such that there is no relative movement between these modules. Furthermore, due in part to the isolation or separation of the vision system  410  from the protective cover  158  and the chassis  306 , a force to the protective cover  158  that causes the protective cover  158  and/or the chassis  306  to bend, warp, or otherwise become altered may result in the further compression of the first spring element  446  and/or the second spring element  448  without i) affecting the fixed distance between the components of the vision system  410 , and ii) without causing mechanical contact between components of the vision system  410  and the chassis  306 . As a result, the vision system  410  may continue to function properly despite external forces causing alterations to the electronic device  100 . 
       FIG.  17    illustrates a plan view of an alternate embodiment of an electronic device  700 , showing the electronic device  700  including a protective cover  718  that covers a display assembly  716 , with the protective cover  718  including a notch  724  and the display assembly  716  including a notch  722 , in accordance with some described embodiments. The electronic device  700  may include features and components described herein for an electronic device. The aforementioned notches are aligned with one another, and are in a location corresponding to a vision system. As shown, the vision system  710  is not directly covered by the protective cover  718 , but may be at least partially hidden by a masking layer  770 . Accordingly, the masking layer  770  may be separate from the protective cover  718 , thereby reducing the required alignment steps between the masking layer  770  and the vision system  710 . Also, the band  702  can be split into its sidewall components in different locations. For example, a first sidewall component  704  of the band  702  is separated from a second sidewall component  706  and a third sidewall component  708  (both of the band  702 ) by a first composite material  712  and a second composite material  714 , respectively. The first composite material  712  and the second composite material  714  are located along different locations of the electronic device  700 , as compared to the first composite material  112  and the second composite material  114  (shown in  FIG.  1   ). 
       FIG.  18    illustrates a plan view of the electronic device  700  shown in  FIG.  17   , with the display assembly and the protective cover removed. The electronic device  700  may include a chassis  730  that provides structural and electrical grounding support. As shown, the vision system  710  may include a first camera module  732 , a light emitting module  734 , and a second camera module  736 . However, as compared to the vision system  410  (shown in  FIG.  8   ), the vision system  710  in  FIG.  18    may include a “modular” design that includes individual modules not held by a bracket assembly and secured by other means. Also, the electronic device  700  may include a battery assembly  740  and a circuit board assembly  750  that combine to surround a camera assembly  756 . As shown, the camera assembly  756  may be centrally located in a location corresponding to an opening (not labeled) of the chassis  730 . Also, the electronic device  700  may further include a wireless charging system  760  located along a corner of the electronic device  700 , in a location corresponding to an additional opening (not labeled) of the chassis  730 . The electronic device  700  may further include an audio module  762 . 
     Electronic devices described herein may vary the position/location of a display assembly with respect to a protective cover. For example, a display assembly may extend substantially (such as 1 millimeter or less) to an edge, or multiple edges, of a protective cover. In another example, a display assembly may extend to an edge, or multiple edges, of a protective cover such that the display assembly and the protective cover share an outer perimeter or outer edge. In other words, the display assembly and the protective cover may include the same size in at least two dimensions.  FIGS.  19  and  20    illustrate various embodiments of electronic devices illustrating the location of the display assembly with respect to the protective cover. It should be noted that electronic devices shown and described in  FIGS.  19  and  20    may include features described herein for an electronic device. 
       FIG.  19    illustrates a cross sectional view of an alternate embodiment of an electronic device  800  that includes a protective cover  818  that covers a display assembly  816 , showing the display assembly  816  extending substantially to the edges of the protective cover  818 , in accordance with some described embodiments. As shown in the enlarged view, the electronic device  800  includes a frame  854  that carries the protective cover  818  and the display assembly  816 , which is adhesively secured to the protective cover  818 . Also, the frame  854  is adhesively secured with the protective cover  818  and a band  802  of the electronic device  800 . The display assembly  816  includes an edge  826  that extends substantially to an edge  828  of the protective cover  818 . It should be noted that the relationship between the edge  826  of the display assembly  816  and the edge  828  of the protective cover  818  may apply in multiple locations. 
     In some instances, the frame can be modified to alter the relationship between the display assembly and the protective cover. For example,  FIG.  20    illustrates a cross sectional view of an alternate embodiment of an electronic device  900  that includes a protective cover  918  that covers a display assembly  916 , showing the display assembly  916  extending to the edges of the protective cover  918 , in accordance with some described embodiments. As shown in the enlarged view, the electronic device  900  includes a frame  954  that carries the protective cover  918  and the display assembly  916 , which is adhesively secured to the protective cover  918 . Also, the frame  954  is adhesively secured with the protective cover  918  and a band  902  of the electronic device  800 . The display assembly  916  includes an edge  926  that is co-planar, or flush, with respect to an edge  928  of the protective cover  918 , as the frame  954  is modified to be external (laterally) with respect to the display assembly  916  and the protective cover  918 . It should be noted that the relationship between the edge  926  of the display assembly  916  and the edge  928  of the protective cover  918  may apply in multiple locations. 
     In some embodiments, an electronic device may include a display assembly that extends laterally over a band to define an outer edge of the electronic device. In other words, when viewing the electronic device from a plan view (that is, when looking down at the electronic device such that the electronic device is viewed in a X-Y plane), the display assembly extends laterally to at least to the dimensions of the band, and in some instances, extends laterally beyond the band. Accordingly, when the display assembly presents visual information, the visual information can be seen along the outer perimeter of the electronic device, due in part to the lateral dimensions of the display assembly. With the display assembly defining an outer edge, or outer perimeter, the electronic device may maximize the area with which visual information is provided to the user. Also, the electronic device may not include a border along the outer edge of the electronic device, as the display assembly can illuminate and present the visual information at the outer edge of the electronic device. It should be noted that the control inputs (buttons and switches, for example) may extend laterally beyond the display assembly, but other features (including the band) do not extend beyond the dimensions of the display assembly. Also, when the display assembly includes a notch that accommodates a vision system, the display assembly may not define the outer perimeter of the electronic device in a location corresponding to the notch. 
       FIG.  21    illustrates an exploded view of an embodiment of a battery assembly  1000 , in accordance with some described embodiments. The battery assembly  1000  is designed for use as an internal power supply for electronic devices described herein. The battery assembly  1000  may include a rechargeable battery assembly that is charged and recharged by an external power supply using, for example, from the port  126  (shown in  FIG.  1   ) receiving power from a cable connector, or a wireless charging system. 
     As shown, the battery assembly  1000  may include a first battery component  1002  and a second battery component  1004 . The first battery component  1002  is in electrical communication with the second battery component  1004  when the battery assembly  1000  is assembled. The first battery component  1002  may include a first housing component  1012  and a second housing component  1014 , with the first housing component  1012  sealed with the second housing component  1014  to form a housing. The housing may define a cavity to shield and enclose internal components, such as a first electrode  1016 , a second electrode  1018 , and a separator  1020 . The separator  1020  provides at least some physical isolation between the first electrode  1016  and the second electrode  1018 , while still allowing the flow of electrical charge between the first electrode  1016  and the second electrode  1018 . As commonly known in the art for a battery, one of the first electrode  1016  and the second electrode  1018  includes an anode, while the remaining electrode (of the first electrode  1016  and the second electrode  1018 ) includes a cathode. Also, as commonly known, electrodes can be used to convert chemical energy into electricity for use by an electronic device (such as the electronic device  100 , shown in  FIG.  1   ). 
     The second battery component  1004  may include a first housing component  1022  and a second housing component  1024 , with the first housing component  1022  sealed with the second housing component  1024  to form a housing. The housing may define a cavity to shield and enclose internal components, such as a first electrode  1026 , a second electrode  1028 , and a separator  1030 . The separator  1030  provides at least some physical isolation between the first electrode  1026  and the second electrode  1028 , while still allowing the flow of electrical charge between the first electrode  1026  and the second electrode  1028 . As commonly known in the art for a battery, one of the first electrode  1026  and the second electrode  1028  includes an anode, while the remaining electrode (of the first electrode  1026  and the second electrode  1028 ) includes a cathode. Also, as commonly known, electrodes can be used to convert chemical energy into electricity for use by an electronic device (such as the electronic device  100 , shown in  FIG.  1   ). 
     Also, the first battery component  1002  may couple with the second battery component  1004  by a coupling member  1006 . The coupling member  1006  may include a first adhesive material  1032  that adhesively secures the coupling member  1006  to the first battery component  1002  (in particular, the second housing component  1014  of the first battery component  1002 ), and a second adhesive material  1034  that adhesively secures the coupling member  1006  to the second battery component  1004  (in particular, the second housing component  1024  of the second battery component  1004 ). However, the coupling member  1006  may adhesively couple with the first battery component  1002  and the second battery component  1004  at the first housing component  1012  and the first housing component  1022 , respectively. 
     The coupling member  1006  may act as a tensile shim that enhances structural stability of the battery assembly  1010 . In this regard, the coupling member  1006  may provide support to the battery assembly  1010  in the event of tensile load across the battery assembly  1010 , thereby preventing damage to the battery assembly  1000 , as well as distributing shock load across regions of the battery assembly  1010 . Also, in some instances, the coupling member  1006  may provide no support in the event of a compressive load force to the battery assembly  1010 , which may be advantageous in unexpected impact events in which the battery assembly  1010  is subjected to an external load, as the relative motion of individual cells (that is, the electrodes in the first battery component  1002  and the second battery component  1004 ) may dissipate energy on impact. Further, the geometry of the coupling member  1006  over the electrodes can be designed to support or avoid specific regions of interest. Further, the first adhesive material  1032  and/or the second adhesive material  1034  may include a reworkable adhesive that allows for easy removal. Also, in order to provide targeted shock absorption, the coupling member  1006  may be used as a shear layer between the battery assembly  1010  and retention adhesives (discussed below) that secure the battery assembly  1000  with an electronic device (not shown in  FIG.  21   ). Further, the coupling member  1006  may wrap around edges of the battery assembly  1010  to provide additional support. 
     Although not shown in  FIG.  21   , other methods for retention of a single-cell battery pack or a multi-cell soft-pack (similar to the battery assembly  1000 ) are available. For example, in some embodiments, a rigid external support structure can be used to retain a rigid geometry for a multiple-cell battery, causing it to behave as a single body. It can also be used to prevent or allow certain types of motion or flexibility as desired. In some embodiments, a rigid external support structure can directly fasten the battery to the housing. In some embodiments, a soft or sprung external support structure can bridge the battery and housing and be used to spread dynamic loads and reduce shock. In some embodiments, an adhesive may be used to directly bond multiple cells. Each embodiment is not necessarily exclusive of the others, and multiple embodiments may be used in concert. 
       FIG.  22    illustrates a plan view of the battery assembly  1000  shown in  FIG.  21   , showing the first battery component  1002  coupled with the second battery component  1004  by the coupling member  1006 . While traditional battery electrodes include a generally rectilinear shape, the electrodes in the battery assembly  1000 , and battery assemblies described herein, may include different shapes. For example, the battery assembly  1000 , when assembled, may resemble an “L-shaped configuration,” that is, the shape of the letter L, in which the combination of the first battery component  1002  and the second battery component  1004  define six different parallel sides or surfaces. Although not shown, the battery assembly  1000  may further include a circuit board that includes one or more circuits designed to monitor electrical current flowing into and out of the battery assembly  1000 . Also, the circuit board, as well as components of the circuit board, may be in electrical communication with a circuit board assembly (discussed below) of an electronic device. 
       FIG.  22    further shows the coupling member  1006  coupled with the first battery component  1002  and the second battery component  1004  using the first adhesive material  1032  and the second adhesive material  1034 , respectively. In order to secure the battery assembly  1000  with an electronic device (such as the electronic device  100  shown in  FIG.  1   ), the coupling member  1006  may secure with a third adhesive material  1042  and a fourth adhesive material  1044 . The third adhesive material  1042  and the fourth adhesive material  1044  may secure with a structural component (such as the chassis  306  shown in  FIG.  7   ). Also, in order to electrically couple the battery assembly with another component, the battery assembly  1000  may include a connector  1050 . 
       FIG.  23    illustrates a cross sectional view of the battery assembly shown in  FIG.  22   , taken along line C-C. As shown, the first adhesive material  1032  is positioned between the first battery component  1002  and the coupling member  1006 , and the second adhesive material  1034  is positioned between the second battery component  1004  and the coupling member  1006 . Although not shown in  FIG.  23   , the coupling member  1006 , the first adhesive material  1032 , and the second adhesive material  1034  may be rearranged such that the coupling member  1006 , the first adhesive material  1032 , and the second adhesive material  1034  lie above the first battery component  1002  and the second battery component  1004  in the Z-dimension. 
     Also, the third adhesive material  1042  may include a dimension  1052 , or height, similar to a combined height of the first adhesive material  1032  and the coupling member  1006 , and the fourth adhesive material  1044  may include a dimension  1054 , or height, similar to a combined height of the second adhesive material  1034  and the coupling member  1006 . Although not shown in  FIG.  23   , the dimension  1052  of the third adhesive material  1042  may be greater than the combined height of the first adhesive material  1032  and the coupling member  1006 , and the dimension  1054  of the fourth adhesive material  1044  may be greater than the combined height of the second adhesive material  1034  and the coupling member  1006 . In this regard, the third adhesive material  1042  may combine with the fourth adhesive material  1044  to suspend the first battery component  1002 , the second battery component  1004 , the first adhesive material  1032 , and the second adhesive material  1034 , such that these structural elements are not in contact with a component (such as the wireless power receiving module  160  shown in  FIG.  7   ). 
       FIGS.  24 - 26    illustrate various embodiments of a battery assembly that may be incorporated into an electronic device described herein. Also, the battery assemblies shown and described in  FIGS.  24 - 26    may include at least some structures and features described herein for a battery assembly.  FIG.  24    illustrates a plan view of an alternate embodiment of a battery assembly  1100 , showing a first battery component  1102  coupled with a second battery component  1104  along a central location of the first battery component  1102 , in accordance with some described embodiments. As shown, a coupling member  1106  can be used to secure the first battery component  1102  with the second battery component  1104 .  FIG.  24    exemplifies that the second battery component  1104  may be located in different positions relative to the first battery component  1102 , and accordingly, the configuration, or shape, the battery assembly  1100  can take on several different configurations. In this regard, the battery assembly  1100  may be reconfigured to form different shapes in order to accommodate other internal component of an electronic device, and avoid engineering design changes to the layout of the internal components of the electronic device. 
       FIG.  25    illustrates a plan view of an alternate embodiment of a battery assembly  1200 , showing the battery assembly  1200  having a housing formed from a unitary body, in accordance with some described embodiments. As shown, the battery assembly  1200  may include a first battery component  1202  and a second battery component  1204 , both of which are housed in the unitary housing of the battery assembly  1200 . This may reduce the total number of parts, thereby reducing manufacturing time of the battery assembly  1200 . 
       FIG.  26    illustrates a plan view of an alternate embodiment of a battery assembly  1300 , showing the battery assembly  1300  having a housing formed from a unitary body and a battery component  1302  positioned in the unitary housing, in accordance with some described embodiments. The battery component  1302  may take on a similar shape as that of the battery assembly  1300 . Accordingly, the battery component  1302  may resemble an L-shape configuration. 
       FIG.  27    is a simplified diagram of a wireless charging system  1400  that includes a transmitter shield  1402  and a receiver shield  1404 , in accordance with some described embodiments. The transmitter shield  1402  may be positioned in front of a transmitter coil  1406  so that magnetic flux  1410  is directed toward the transmitter shield  1402 . For instance, the transmitter shield  1402  is positioned between a transmitter coil  1406  and a receiver coil  1408  during wireless power transfer so that the magnetic flux  1410  first passes through the transmitter shield  1402  before reaching the receiver coil  1408 . In some embodiments, the transmitter shield  1402  can be positioned between the transmitter coil  1406  and an interface  1416  when an electronic device (such as the electronic device  100 , shown in  FIGS.  1  and  2   ) rests on a wireless charging device (not shown in  FIG.  27   ) to perform wireless power transfer to the electronic device. The transmitter shield  1402  and the transmitter coil  1406  can both be positioned within the wireless charging device. The transmitter shield  1402  can be substantially transparent to the magnetic flux  1410  (meaning the transmitter shield  1402  provides minimal disruption of the magnetic flux  1410 ) so that the receiver coil  1408  receives a substantial percentage of the magnetic flux  1410  generated by the transmitter coil  1406 . 
     While the transmitter shield  1402  can be substantially transparent to the magnetic flux  1410 , the transmitter shield  1402  can, on the other hand, be substantially opaque to an electric field  1418  such that the transmitter shield  1402  substantially blocks the electric field  1418 . This prevents the electric field  1418  from exposing on the receiver coil  1408  (that can be positioned in an electronic device) and generating a detrimental voltage on the receiver coil  1408 . Due in part to the transmitter shield  1402  substantially blocking the electric field  1418  before the electric field  1418  can reach the receiver coil  1408 , the electric field  1418  may generate voltage on the transmitter shield  1402  instead of the receiver coil  1408 . The amount of voltage generated on the transmitter shield  1402  may correspond to the amount of voltage that would have been generated on the receiver coil  1408  had the transmitter shield  1402  not been present. 
     In some embodiments, voltage generated on the transmitter shield  1402  can be removed so that the voltage does not permanently remain on the transmitter shield  1402 . As an example, voltage on the transmitter shield  1402  can be discharged to ground. Thus, transmitter shield  1402  can be coupled to a ground connection  1422  that allows voltage on the transmitter shield  1402  to be discharged to ground. The ground connection  1422  can be a ground ring or any other suitable conductive structure coupled to ground that can remove voltage from the transmitter shield  1402 . 
     Similar to the transmitter shield  1402 , the receiver shield  1404  may also be implemented in the wireless charging system  1400  to prevent detrimental voltage from being generated on the transmitter coil  1406  from an electric field  1424  generated by the receiver coil  1408 . The receiver shield  1404  may be positioned in front of the receiver coil  1408  so that the magnetic flux  1410  first passes through the receiver shield  1404  before reaching the receiver coil  1408 . In some embodiments, the receiver shield  1404  and the receiver coil  1408  are positioned within a wireless power receiving module, which in turn is positioned within an electronic device (such as the electronic device  100 , shown in  FIGS.  1  and  2   ). Within the wireless power receiving module, the receiver shield  1404  can be positioned between the interface  1416  and the receiver coil  1408  when the electronic device rests on a wireless charging device to perform wireless power transfer. 
     Similar to the transmitter shield  1402 , the receiver shield  1404  can be substantially transparent to the magnetic flux  1410  so that a substantial percentage of the magnetic flux  1410  generated by the transmitter coil  1406  passes through the receiver shield  1404  and is received by the receiver coil  1408 , while the receiver shield  1404  can be substantially opaque to the electric field  1424  such that the receiver shield  1404  substantially blocks the electric field  1424 . This prevents the electric field  1424  from reaching the transmitter coil  1406  and generating a detrimental voltage on the transmitter coil  1406  while enabling wireless power transfer. Like the transmitter shield  1402 , the receiver shield  1404  may also be grounded so that voltage generated by the electric field  1424  may be discharged to a ground connection  1426 . The ground connection  1426  may be a structure similar to the ground connection  1422  in some embodiments, or it may be the same structure as the ground connection  1422  in other embodiments. 
     By incorporating the transmitter shield  1402  and the receiver shield  1404  into the wireless charging system  1400 , the wireless charging device and the electronic device within which the transmitter shield  1402  and the receiver shield  1404  are implemented, respectively, are exposing their grounds to each other. This mutes any ground noise caused by the electrical interactions between the transmitter coil  1406  and the receiver coil  1408 . As can be appreciated by disclosures herein, the transmitter shield  1402  and the receiver shield  1404  are shielding structures that are able to block the passage of electric fields, yet allow the passage of magnetic flux. Also, in some embodiments, a transmitter shield can be included in a wireless charging device, such as a wireless charging mat, and a receiver shield can be included within a wireless power receiving module included within a portable electronic device configured to rest on the wireless charging device to wirelessly receiver power from the wireless charging mat. 
       FIG.  28    illustrates an exploded view of a wireless power receiving module  1500  that can be incorporated into an electronic device  1600  to receive power by magnetic induction, in accordance with some described embodiments. For purposes of simplicity, several components of the electronic device  1600  are removed. However, the electronic device  1600  may include any features described herein for an electronic device. Also, the housing may include a band  1602  and a protective cover  1658 . The band  1602  and the protective cover  1658  may include any material previously described for a band and a protective cover, respectively. For example, the band  1602  may include a material, such as stainless steel or aluminum, as non-limiting examples, and the protective cover  1658  may include a non-metal, such as glass, as a non-limiting example. Also, the electronic device  1600  may further include a chassis  1606  formed from a metal. However, the chassis  1606  may include an opening  1608  defining a through hole in the chassis  1606 . The protective cover  1658  may cover the opening  1608 . 
     The wireless power receiving module  1500  may be incorporated with the electronic device  1600  in order to receive, and subsequently provide, electrical energy to a battery assembly (not shown in  FIG.  28   ). Also, the wireless power receiving module  1500  may be positioned in the opening  1608  of the chassis  1606 . Accordingly, the opening  1608  may include a size and shape to receive the wireless power receiving module  1500 . Also, the wireless power receiving module  1500  can include several separate shields. For example, the wireless power receiving module  1500  may include an integrated coil and electromagnetic shield  1502 , a ferrite shield  1504 , and a thermal shield  1506 . Also, an adhesive component  1508  may attach the wireless power receiving module  1500  to the protective cover  1658 . Although not shown, an additional non-metal structural element may be positioned between the protective cover  1658  and the wireless power receiving module  1500 . 
     The integrated coil and electromagnetic shield  1502  can act as, for example, a receiver coil and a receiver shield, similar to the receiver coil  1408  and the receiver shield  1404  (shown in  FIG.  27   ). In this manner, the integrated coil and electromagnetic shield  1502  may enable the wireless power receiving module  1500  to wirelessly receive power transmitted from a wireless power transmitting coil, such as the transmitter coil  1406  (shown in  FIG.  27   ). When positioned within the electronic device  1600 , the receiver shield portion of the integrated coil and electromagnetic shield  1502  may be positioned between the receiver coil portion and the charging surface of the electronic device  1600  (which may be defined in part by the protective cover  1658 ). Thus, the receiver shield is positioned between the receiver coil and the transmitter coil and serves to prevent capacitive coupling to the transmitter coil in a wireless charging device (not shown in  FIG.  28   ) used to induce a current to the wireless power receiving module  1500 . The ferrite shield  1504  acts as a magnetic field shield, or B-field shield, that redirects magnetic flux to increase coupling to the transmitter coil resulting in improved charging efficiency and helping prevent magnetic flux interference. The thermal shield  1506  can include a graphite or similar layer that provides thermal isolation between wireless power receiving module  1500  and the battery (not shown in  FIG.  28   ), as well as other components of the electronic device in which the wireless power receiving module  1500  is incorporated. The thermal shield  1506  can also include a copper layer that is tied to an electrical ground and contributes to the thermal shielding while also capturing stray flux. 
     Although not shown, some embodiments of portable electronic devices may include a circuit board assembly that includes a first circuit board and a second circuit board. In some embodiments, each of the first circuit board and the second circuit board includes a printed circuit board. The first circuit board may be secured with, and positioned over, the second circuit board in a stacked configuration. Also, the first circuit board can include a size and shape that is the same as, or at least substantially similar to, the size and shape of the second circuit board. However, in some embodiments, the first circuit board includes at least some differences, as compared to the second circuit board, with regard to size and/or shape. While the stacked configuration of the circuit board assembly increases the footprint of the circuit board assembly in an electronic device (such as the electronic device  100  shown in  FIG.  1   ) in one dimension, the stacked configuration decreases the footprint of the circuit board assembly in other dimensions. This additional space provided by stacking the aforementioned circuit boards may provide additional space in an electronic device for other components, such as the battery assembly  1000  (shown in  FIG.  21   ). 
     The first circuit board and/or the second circuit board may include several operational components. An “operational component” may refer to an integrated circuit or processor circuit that performs an operation (or operations) such as executing instructions from a software application that is stored on a memory circuit, as non-limiting examples. An operational component may also refer to a transistor. The circuit boards may include operational components on multiple surfaces. For example, the first circuit board may include a first mounting surface and a second mounting surface opposite the first mounting surface, with the first mounting surface having a first operational component and the second mounting surface having a second operational component. Both the first mounting surface and the second mounting surface may include additional operational components. Also, it should be noted that the operational components on the first circuit board are in electrical communication with each other. The communication means may include, for example, at least one via that extends through the first circuit board. 
     The second circuit board may include a first mounting surface that includes several operational components, such as an operational component. The second circuit board also includes a second mounting surface opposite the first mounting surface. The second mounting surface of the second circuit board may also include operational components. In some embodiments, the second mounting surface includes an operational component (or components) in electrical communication with the operational components located on the first mounting surface. Also, it should be noted that when the circuit board assembly is assembled, the second circuit board is overlaid (or covered) by the first circuit board in the stacked configuration. However, it should be noted that the first circuit board is still separated from the second circuit board by at least some gap or space. Also, when the circuit board assembly is assembled, the first mounting surface of the second circuit board is facing the second mounting surface of the first circuit board, and vice versa. 
     The first circuit board may mechanically connect with the second circuit board by several standoffs connected with rivets. The standoffs are designed to not only provide mechanical connections, but also to maintain a desired distance between the first circuit board and the second circuit board such that components on the second mounting surface of the first circuit board do not interfere (physically) with components on the first mounting surface of the second circuit board, and vice versa. Also, the positioning of the standoffs and the rivets may be reversed such that the first circuit board includes the standoffs and the second circuit board includes the rivets. 
     In order to electrically couple the first circuit board with the second circuit board, several interposers may be used to route electrical signals between the first circuit board and the second circuit board. For example, the first circuit board may include several interposers electrically coupled with the second circuit board by, for example, a soldering operation. Also, the first circuit board and the second circuit board may include several metal traces that electrically couple the interposers with one or more operational components on the second circuit board. Also, when the first circuit board is electrically coupled to the second circuit board, each of the interposers may electrically couple with one or more metal traces on the second mounting surface of the first circuit board, and the first mounting surface of the second circuit board. 
     The circuit board assembly may include several shielding elements that shield the components of the circuit board assembly from electromagnetic interference (“EMI”). For example, the circuit board assembly may include a first shielding element that covers components located on the first mounting surface of the first circuit board. The first shielding element may include a metal-based material designed to provide an EMI shield to the components on the first mounting surface. The circuit board assembly may further include a second shielding element designed to provide an EMI shield for components located on the second mounting surface of the first circuit board and the first mounting surface of the second circuit board. The second shielding element may include a metal, such as copper or brass. The second shielding element may secure with (and between) the first circuit board and the second circuit board by several solder joints disposed on each circuit board. The first circuit board may also include solder joints in locations corresponding to locations of the solder joints on the second circuit board. In some embodiments, the second shielding element includes several discontinuous structural elements. In other embodiment, the second shielding element may include a single, continuous structural component designed to extend along an outer perimeter of the circuit board assembly. Alternatively, the second shielding element may include several shielding element parts that combine with one another to form the second shielding element. 
     The circuit board assembly may further include a third shielding element positioned on the second mounting surface of the second circuit board. The third shielding element may include a metal-based material designed to provide an EMI shield to the components on the second mounting surface of the second circuit board. Also, the third shielding element is designed to combine with the first shielding element and the second shielding element to provide an EMI shield to the circuit board assembly. Also, the second mounting surface of the second circuit board may include metal traces (throughout the second mounting surface). In this regard, in addition to forming an EMI shield, the third shielding element may define at least part of an electrical ground path for the circuit board assembly, as the third shielding element is electrically connected to the second mounting surface by way of the metal traces. Also, when the component (or components) of the circuit board assembly generates EMI during operation, the aforementioned shielding elements may shield components of an electronic device (such as the electronic device  100  shown in  FIG.  1   ) that are external with respect to the circuit board assembly from EMI generated by the component(s) of the circuit board assembly. 
       FIG.  29    illustrates an isometric view of an embodiment of a trim  1800  designed for a use with a camera assembly in an electronic device described herein, in accordance with some described embodiments. The trim  1800  can include a surface  1802  and a first lip  1804  that extends from the surface  1802  to define a receptacle  1806 . The trim  1800  may include a first opening  1808  and a second opening  1810  formed as through holes in the surface  1802 , with the first opening  1808  and the second opening  1810  providing access for camera modules (not shown in  FIG.  29   ) that can be enclosed by the trim  1800 . The trim  1800  may further include a third opening  1812  formed as a through hole in the surface  1802  at a location between the first opening  1808  and the second opening  1810 . The third opening  1812  that can provide access to a light emitter (not shown in  FIG.  29   ), such as a strobe module designed to provide additional lighting during an image capture event by the aforementioned camera modules. The trim  1800  may additionally include a fourth opening  1814  formed as a through hole in the surface  1802  that can serve as an inlet opening for an audio transducer (not shown in  FIG.  29   ). The trim  1800  may further include a second lip  1816  that extends from the surface  1802 , and along a perimeter of the third opening  1812 . As shown in  FIG.  29   , the surface  1802  can be recessed with respect to the first lip  1804  and the second lip  1816 . The first lip  1804  can cooperate with the second lip  1816  to define the receptacle  1806 . The receptacle  1806  may include a shape that is complementary to a camera cover glass (not shown in  FIG.  29   ) so that the receptacle  1806  can receive the camera cover glass. The height of first lip  1804  and the second lip  1816  can be generally equal to the thickness/height of a camera cover glass. Hence, when a camera cover glass is placed on the surface  1802 , a surface (parallel to the surface  1802 ) of the first lip  1804  and the second lip  1816  can be exposed and be flush with the exterior surface of camera cover glass. The exposed surfaces of the first lip  1804  and the second lip  1816  can serve as cosmetic surfaces. 
       FIG.  30    illustrates an isometric view of the trim  1800  shown in  FIG.  29   , oriented at a different angle to show an internal region of the trim  1800 . The trim  1800  can include a perimeter wall  1818  that defines an internal volume  1820  of the trim  1800 . The perimeter wall  1818  can be used to enclose the audio and optical components of an input/output (“I/O”) assembly such as the camera modules, the light emitter, and the audio transducer (not shown in  FIG.  30   ). The trim  1800  can also include internal wall  1822  that can define an internal chamber  1824  of the trim  1800 . As shown, the internal chamber  1824  may be located between the first opening  1808  and the second opening  1810 . A light emitter (not shown in  FIG.  30   ) can be positioned within the internal chamber  1824  so that the internal wall  1822  can at least partially block light emitted from the light emitter from leaking into any of the camera modules. Additionally, an audio transducer can also be positioned within the internal chamber  1824 . The internal chamber can include one or more keys, such as a first key  1826  and a second key  1828 , used to align the light emitter and the audio transducer. 
       FIG.  31    illustrates a partial cross sectional view of a portion of an electronic device  1900 , showing the electronic device  1900  including the trim  1800  shown in  FIGS.  29  and  30   , along with multiple camera modules and a light emitter, in accordance with some described embodiments. As shown, the electronic device  1900  may include a camera module housing  1902  that can carry a circuit board  1904  within a cavity of camera module housing  1902 . The circuit board  1904  can carry, and electrically couple to, a first camera module  1906  and a second camera module  08 . As shown, the first camera module  1906  and the second camera module  1908  can extend partially outside of the camera module housing  1902 . The camera module housing  1902  can be enclosed in the internal volume  1820  of the trim  1800 . The trim  1800  can receive a cover glass  1910 . The cover glass  1910  may secure with the trim  1800  by adhesives. The first lip  1804  and the second lip  1816  can be co-planar, or flush, with respect to an exterior surface of cover glass  1910 . Also, the cover glass  1910  may include an opaque layer  1912 . However, the opaque layer  1912  may define a pair of openings, with one opening aligning with the first camera module  1906  and another opening aligning with the second camera module  1908  so that the camera modules can captures still and/or dynamic images. 
     The internal chamber  1824  (shown and labeled in  FIG.  30   ), defined by the internal wall  1822 , is designed to receive a light emitter  1920  (or strobe module) as well as a window  1922  such that the light emitter  1920  and the window  1922  are enclosed by the internal wall  1822 . The light emitter  1920  and the window  1922  may align with an opening  1914  (or through hole) in the cover glass  1910 . Also, the window  1922  can be positioned sub-flush with respect to the cover glass  1910  and the second lip  1816 . By separating the window  1922  and the cover glass  1910 , and by enclosing the window  1922  with the second lip  1816 , light emitted from the light emitter  1920  can be prevented from entering the cover glass  1910 , and in particular, from entering the first camera module  1906  and the second camera module  1908 . As shown, the second lip  1816  can internally surround the opening  1914  the cover glass  1910 . In this regard, the second lip  1816  can serve as a wall that blocks light emitted from light emitter  1920  from reaching the cover glass  1910 , and directly or reflectively leaking into any of the first camera module  1906  or the second camera module  1908 . 
     One design concern of the position of a strobe in a portable electronic device is that light may be leaked or reflected to camera by a part of the portable electronic device. Such unintended leakage or reflection deteriorates the quality of the images because, instead of being reflected by the targeted objects at the focal point, some of the light is reflected by some very nearby objects that can result in glares in the images. Such potential problem can be worsened when the portable electronic device is coupled to an external object, such as a protective case. If the potential reflection of light of the strobe is not taken into account when designing a protective case, the edges of the opening for the strobe of the protective case may reflect the light and deteriorate the quality of the images. Hence, the edge of an opening for the strobe of a case may need special design. A third party manufacturer of protective cases may not be aware of the potential problem and unintentionally design cases that could adversely affect the image quality of a camera. 
     However, as shown in  FIG.  31   , the light emitter  1920  is positioned between first camera module  1906  and second camera module  1908 . This configuration may provide significant advantages over conventional placement of a strobe relative to a camera. For example, due in part to the light emitter  1920  being positioned between the first camera module  1906  and the second camera module  1908 , the area surrounding the light emitter  1920  is the area that is occupied by the first camera module  1906  and the second camera module  1908 . As a result, the edge of an opening of any protective case that may receive the electronic device  1900  will be relatively distant from the light emitter  1920 . Hence, any potential unintentional leakage or reflection of light can be addressed by the image quality of the camera modules would not be affected by the protective case or any other accessories added to the electronic device  1900 . 
     To further prevent leakage of light from the light emitter  1920  to any of the camera modules, particularly against internal leakage, a sealing member  1924  can engage the light emitter  1920 . The sealing member  1924  can be a ring shaped structure (hence, shown as two portions in the cross-section view of  FIG.  31   ) that engages with the perimeter of light emitter  1920 . The sealing member  1924  can be a compression-molded piece that can be formed from an elastic and opaque material(s). The sealing member  1924  can serve multiple purposes. First, the sealing member  1924  can fill the remaining space of the internal chamber  1824  (defined by the internal wall  1822 ) so that the light emitter  1920  can be isolated from the first camera module  1906  and the second camera module  1908 , thereby preventing the first camera module  1906  and the second camera module from directly receiving light from the light emitter  1920 . Second, the sealing member  1924  can also force the light emitter  1920  and the window  1922  against the trim  1800  so that the light emitter  1920  and the window  1922  are secured in placed. Third, based on the position of the sealing member  1924 , light emitted from the light emitter  1920  is prevented from reaching a first light sensor  1926  and second light sensor  1928 , both of which are on the circuit board  1904 .
