CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation patent application of U.S. patent application Ser. No. 13/251,039, filed Sep. 30, 2011 and titled “Systems and Methods for Coupling Electrically Isolated Sections of an Electronic Device,” which claims the benefit of U.S. provisional patent application No. 61/529,710, filed Aug. 31, 2011 and titled “Systems and Methods for Coupling Electrically Isolated Sections of an Electronic Device,” the disclosures of which are hereby incorporated by reference herein in their entireties. 
    
    
     FIELD OF THE INVENTION 
     Systems and methods are disclosed for coupling sections of an electronic device. In particular, components of an electronic device can be assembled from two or more sections, where these sections may be coupled together using knuckles. 
     BACKGROUND OF THE DISCLOSURE 
     A portable electronic device can be constructed using different approaches. In some cases, an electronic device can be constructed by assembling several components together. These “components” can include external components that are combined to form a device enclosure (e.g., a device “housing”), as well as internal components that may provide structural support or other functionality for the electronic device (e.g., the internal component could be a microchip). Based on the design of the electronic device, the components can be formed from any suitable material(s) such as metals, plastics, or any other materials. 
     In some cases, the various components of the electronic device can operate as part of an electrical circuit. For example, a particular component could serve as a resistor or as a capacitor to another part of the electronic device. As another example, a component can function as part of an antenna assembly of the electronic device. If the component is used in only a single electrical circuit, then the component may be constructed from a single piece of conductive material. If the same component, however, is used in several different electrical circuits, the component may need to be constructed from several “sections” of conductive elements. In this case, however, it may be necessary to separate each of the conductive sections with an insulating or other non-conductive material, in order to ensure that each section operates in its own electrical circuit correctly. 
     SUMMARY OF THE DISCLOSURE 
     This is directed to systems and methods for coupling sections of an electronic device. In some embodiments, an electronic device can be formed from several components, such as an outer periphery component and/or other components. The outer periphery component may provide a housing structure for the electronic device by encircling the electronic device. In some cases, this outer periphery component can be assembled from two or more “sections.” Knuckles may then be used to couple these sections together. 
     Each knuckle is molded in and/or around a coupling structure that is either welded to or is an integral part of the section. The coupling structure can be a bracket that is welded to an inner surface of a section, and the bracket can be constructed to have a cross-section that minimizes capacitance. In one embodiment, a first bracket can be welded to a first conductive section, and a second bracket can be welded to a second conductive section. A knuckle constructed from an insulating material that is overmolded within and around the first and second brackets such that the first and second conductive sections are coupled together. The first and second conductive sections and their respective brackets are spaced a predetermined distanced apart, thereby ensuring the conductive sections are electrically isolated. In another embodiment, a knuckle can physically couple two conductive sections together by interfacing with a bracket of a first conductive section and by interfacing with an integral coupling structure of a second conductive section.

     DETAILED DESCRIPTION OF THE DISCLOSURE 
     An electronic device can include several components assembled together to form internal and/or external features of the electronic device. For example, one or more internal components (e.g., electrical circuitry and/or internal support structures) can be placed within external components (e.g., housing structures) to provide an electronic device having desired functionality. As used herein, the term “component” refers to a distinct entity of an electronic device, such as a particular electronic circuit (e.g., a microchip), a member forming the housing of the electronic device (e.g., a backplate, an outer periphery component, and the like), an internal support structure (e.g., a mid-plate), and the like. 
     In some cases, a component can be manufactured by assembling and connecting two or more different individual elements (i.e., “sections”) together. As used herein, the term “section” refers to an individual portion of a component, where that component may be formed from multiple sections. The various sections of the component may then be coupled together using a “knuckle.” Based on the desired functionality and design of the component and its sections, these knuckles can exhibit a wide range of shapes and structures. For example, the knuckles can include structural designs that reinforce the knuckle at areas of high mechanical strain, that counteract twisting movements at areas of high torsion, that interlock two sections together such that they are mechanically coupled together, that provide electrical isolation between the sections, and the like. 
       FIG. 1  shows a schematic view of an illustrative component of an electronic device in accordance with some embodiments of the present invention. In particular,  FIG. 1  shows outer periphery component  100  that can be constructed by connecting several sections together, such as sections  110 ,  120 ,  130 , and  140 . Outer periphery component  100  can be constructed to form an exterior, periphery surface for an electronic device. In particular, outer periphery component  100  can surround or wrap around some or all of the internal components (e.g., electronic circuits, internal support structures, and the like) of the electronic device. In other words, outer periphery component  100  can define an internal volume into which internal components can be placed. 
     The thickness, length, height, and cross-section of outer periphery component  100  can be selected based on any suitable criteria including, for example, based on structural requirements (e.g., stiffness or resistance to bending, compression, tension or torsion in particular orientations). In some embodiments, outer periphery component  100  can serve as a structural member to which other electronic device components can be mounted. Some of the structural integrity of outer periphery component  100  can come from the closed shape that it defines (e.g., outer periphery component  100  forms a loop, thus providing structural integrity). 
     Outer periphery component  100  can have any suitably shaped cross-section. For example, outer periphery component  100  can have a substantially rectangular cross-section. Each corner of the substantially rectangular cross-section can be rounded in shape, thus forming a “spline.” As used herein, the term “spline” refers to a rounded corner portion of an outer periphery component. In some embodiments, outer periphery component  100  can have a cross-section in any other suitable shape including, for example, a circular shape, an oval shape, a polygonal shape, or a curved shape. In some embodiments, the shape or size of the cross-section of outer periphery component  100  can vary along the length or width of the electronic device (e.g., an hourglass shaped cross-section). 
     Outer periphery component  100  of the electronic device can be constructed using any suitable process. In some embodiments, outer periphery component  100  can be constructed by connecting section  110  and section  120  together at interface  112 , connecting section  120  and section  130  together at interface  122 , connecting section  130  and section  140  together at interface  132 , and connecting section  140  and section  110  together at interface  142 . Although outer periphery component  100  is illustrated in  FIG. 1  as being constructed from four sections, one skilled in the art could appreciate that outer periphery component  100  could alternatively be formed from any suitable number of two or more sections, and that the interfaces between the sections may be positioned at any location on outer periphery component  100 . 
     Each section  110 ,  120 ,  130 , and  140  can be constructed individually and later assembled to form outer periphery component  100 . For example, each section can be individually constructed using one or more of stamping, machining, working, casting, or any combinations of these. In some embodiments, the materials selected for sections  110 ,  120 ,  130 , and  140  can be conductive, thus allowing the sections to provide an electrical functionality for the electronic device. For example, sections  110 ,  120 ,  130  and/or  140  can be formed from a conductive material such as stainless steel or aluminum. In some embodiments, each section may serve as an antenna for the electronic device. 
     To mechanically couple individual sections together, knuckles  114 ,  124 ,  134 , and  144  can exist at interfaces  112 ,  122 ,  132 , and  142  respectively. In some embodiments, each of the knuckles can be constructed from a material that can begin in a first state and may subsequently change to a second state. As an illustration, the knuckles can be constructed from a plastic that begins in a first, liquid state and then subsequently changes to a second, solid state. While in the liquid state, the plastic can be allowed to flow into interfaces  112 ,  122 ,  132 , and  142 . After flowing into these interfaces, the plastic material may subsequently be allowed to harden into knuckles  114 ,  124 ,  134 , and  144  (e.g., the plastic material is allowed to change into the second, solid state). Upon changing into the solid state, the plastic material may then bond together sections  110  and  120 ,  120  and  130 , and  140  and  110 , respectively, thus forming a single new component (e.g., outer periphery component  100 ). In one embodiment, knuckle  134  may be cosmetic and not physically couple sections  130  and  140  together. In this embodiment, sections  130  and  140  can be welded together so that they are physically and electrically coupled. In another embodiment, knuckle  134  may physically couple sections  130  and  140  together in accordance with principles of the invention. 
     Knuckles  114 ,  124 , and  144  not only physically couple together sections  110  and  120 ,  120  and  130 , and  140  and  110 , respectively, they electrically isolate section  110  from section  120 , section  120  from section  130 , and section  140  from section  110 . For purposes of this discussion, assume sections  130  and  140  are electrically the same because they are welded together, and that knuckle  134  is cosmetic. As will be explained in more detail below, knuckles  114 ,  124 , and  144  encapsulate and/or exist with coupling structures that are attached to or integrally formed parts of sections  110 ,  120 ,  130 , and  140 . That is, when the knuckle in its first state (e.g., the liquid state), it flows into and/or around the coupling structures. A shutoff device (not shown) may be positioned at each interface to shape the knuckle for when it transforms into its second state (e.g., the solid state). As shown in  FIG. 1 , knuckles  114  and  124  are asymmetric in shape and knuckle  144  is symmetric in shape. 
     The coupling structures (not shown) exist on sections  110 ,  120 ,  130 , and  140 . Some sections (e.g., sections  110  and  120 ) may have two coupling structures whereas other sections (e.g., sections  130  and  140 ) have one coupling structure for interfacing with a knuckle. In some embodiments, the coupling structure can be a bracket such as that shown, for example, in  FIG. 2 . The bracket can be attached or welded to an inside surface of a section. In another embodiment, the coupling structure can be an integrally formed part of the section that was originally part of the section. In  FIG. 1 , knuckle  114  interfaces with a bracket and an integrally formed coupling structure and knuckles  124  and  144  interface with two brackets. 
     Any suitable process can be used to place the knuckle material into interfaces  112 ,  122 ,  132 , and  142 , and any suitable process can be used to change the knuckle material from the first state to the second state. In some embodiments, a “molding process” can be used in which the knuckle material is initially inserted in a liquid state and then is subsequently hardened. For example, one or more of injection molding, compression molding, transfer molding, extrusion molding, blow molding, thermoforming, vacuum forming, or rotomolding processes can be used. In this case, a “one shot” process can be used in which the knuckle material is inserted in a single step, and then independently changes to its second state. In other words, the knuckle can be formed in a single step (e.g., in “one shot”) without necessitating additional steps or manufacturing processes. 
     The knuckle material may be any material suitable for mechanically coupling two sections together and electrically isolate the two section. The knuckle material may be a plastic such as a thermal plastic. In one embodiment, the knuckle material may be a glass filled nylon. 
       FIGS. 2A-G  show several views of an illustrative bracket  200  in accordance with an embodiment of the invention that can be mounted to one of the sections. In particular,  FIGS. 2A-G  show back, top, front, left, right, bottom, and isometric views respectively of bracket  200 . Bracket  200  can include three legs  210 ,  220 , and  230 , which extend from planer member  240 . Legs  210  and  220  may both extend away from planer member  240  at a right angle (e.g., 90 degrees), whereas leg  230  may extend away from leg  230  at angle between 1 and 90 degrees. Leg  230  can have slot  232  to promote flow of knuckle material when it is in its first state. In addition, plate  240  can have through-hole  242  or a cutout of any suitable shape to promote flow of knuckle material when in its first state. Legs  210 ,  220 , and  230  may have feet  214 ,  224 , and  234 , respectively, for being welded to a surface of one of the sections. 
     Bracket  200  can be constructed from any suitable material. In some embodiments, bracket  200  is constructed from a conductive material such as metal (e.g., steel or aluminum). In some embodiments, bracket  200  is constructed from the same material as the section it is being welded to. For example, bracket  200  and the section it is being welded to can both be constructed from stainless steel. 
     It is understood that brackets of any suitable construction can be used in connection with the sections. For example,  FIGS. 2H-2N  shows several views of bracket  250  constructed in accordance with an embodiment of the invention. Bracket  250  is similar in many respects to bracket  200  as it includes legs and welding feet, as well as a cutout for promoting knuckle material flow. However, bracket  250  may be dimensioned slightly smaller than bracket  200 , for example, to better fit in a curved portion of a section. 
     Referring now to  FIGS. 3A and 3B , illustrative views of bracket  200  welded to section  300  are shown. In particular,  FIG. 3A  shows an illustrative cross-sectional view and  FIG. 3B  shows an illustrative top view. Bracket  200  is shown sitting within recess  310  of section  300 . Recess  310  may have been machined out of section  300  during or after manufacture of section  300 . Recess  310  may serve as a vessel for retaining a portion of a knuckle as it transitions from its first to second state. As shown, feet  214 ,  224 , and  234  are welded to recess  310 . This weld physically anchors bracket  200  to section  300  and electrically couples bracket to section  300 . 
     The edge of bracket  200  aligns with the edge of section  300 . This alignment may be a product of a cutting operation that physically cuts away a portion of bracket  200  and section  300 . It is the total cross-sectional area of the aligned edges of bracket  200  and section  300  that control capacitance of the knuckle coupling two sections together. Smaller cross-sections generally result in less capacitance. In embodiments where the section is used as an antenna, lower capacitance enhances antenna performance. The cross-sectional area can be varied, for example, by increasing the thickness of bracket  200  or using a bracket that has a different cross-sectional shape. See  FIG. 4  as an example of another bracket  400  having a different cross-sectional shape. 
       FIG. 5A  shows an illustrative enlarged perspective view of sections  110  and  140  (of  FIG. 1 ) having respective brackets  200  welded thereto in accordance with an embodiment of the invention.  FIG. 5A  also shows contact members  520  and  540  welded to top of the planer member of each bracket  200 . Contact members  520  and  540  have a cutout that mimics cutout  242  of bracket  200  and that promotes flow of knuckle material when it is in its first state. A portion of contact members  520  and  540  will be left exposed after the knuckle material encapsulates brackets  200  and members  520  and  540 . The exposed portion may provide a solder pad for connecting a conductor (e.g., an antenna conductor) so that it is electrically coupled to one of sections  120  or  140 . 
     Gap  510  exists between the side walls of sections  110  and  140 . Gap  510  may have a predetermined distance that is maintained between the side walls and brackets  200  during application of the knuckle material. When the material is applied, it can flow in and around brackets  200 , members  520  and  540 , and fill the recesses in which brackets  200  sit. After the material cures, resulting knuckle  144  ( FIG. 5B ) is provided. 
       FIG. 5B  shows a perspective view of knuckle  144  in accordance with an embodiment of the invention. As shown, knuckle  144  physically couples sections  100  and  140  together but ensures they are electrically isolated by the distance of gap  510 . Portions of contact members  520  and  540  are exposed even though knuckle  144  is cured. It is understood that contact members  520  and  540  are optional and are not necessary for each knuckle. For example, knuckle  124  may not encapsulate any contact members. 
       FIG. 6A  shows a perspective view of knuckle  124  of  FIG. 1  in accordance with an embodiment of the invention. Knuckle  124  can encapsulate two brackets (not shown) and mechanically couple sections  120  and  130  together, and ensures they are electrically isolated by gap  710 .  FIGS. 6B and 6C  show a perspective view and a top view, respectively of brackets  200  and  250  mounted to sections  120  and  130 , respectively. Bracket  250  is dimensioned a little smaller than its counterpart bracket  200  and thus may be better suited for being mounted in curved sections, such as section  120 . 
       FIG. 7  shows a cross-sectional view taken along line A-A of  FIG. 6A . The cross-sectional view shows side wall  732  of section  130 , knuckle  124 , and bracket  200 . Also shown is vertical center axis  701  which is aligned with plate member  240 . Horizontal center axis  702  is also shown to bisect plate member  240 . Equal thicknesses of knuckle  124  exist on both sides of center axes  701  and  702 . This ensures knuckle  124  is even distributed about the bracket and provides optimal mechanical coupling strength. 
       FIGS. 8A-C  show various illustrative views of interface  112  in accordance with embodiments of the invention.  FIG. 8A  shows bracket  250  mounted to section  120  and it also shows integrated coupling structure  850 .  FIGS. 8B and 8C  show knuckle  114  interfacing with bracket  250  and coupling structure  850 . 
       FIG. 9  shows an illustrative process for mechanically coupling two conductive sections together in accordance with an embodiment of the invention. Beginning at step  910  first and second conductive sections are provided. The conductive sections each have an inner surface and a side wall. For example, the conductive sections can be sections  110  and  120  of  FIG. 1 . The sections are discrete components that have been previously machined or manufactured. If desired, a recess can be machined out of a portion of each section, and in particular a portion of the inner surface. 
     At step  920 , a first bracket is welded to the inner surface of the first conductive section and a second bracket welded to the inner surface of the second conductive section. The brackets can be seen in  FIG. 2 , for example. The welds physically and electrically couple the brackets to their respective sections. In some embodiments, the brackets can be welded within a recess of the section. In other embodiments, contact members (e.g., as shown in  FIG. 5 ) may be welded to the brackets. 
     At step  930 , the first and second sections are secured in place and a gap of a predetermined distance is machined between the two sections. The machining precisely cuts away a portion of each section and a portion of the brackets, and in some embodiments, may cut away a portion of the contact member if present. The resulting gap is maintained because the sections are secured. 
     At step  940 , a knuckle is molded within and around the first and second brackets to mechanically couple the first and second conductive sections together, wherein the sidewalls of the first and second conductive sections are separated by the gap of a predetermined distance that is occupied by a portion of the knuckle. During molding of the knuckle, a shutoff device may be applied to the sections to shape and control the flow of knuckle material. The knuckle material surrounds the bracket (and optional contact member) and fills in the recess when in its molten or liquid state. 
     At step  950 , a cosmetic finishing process is applied to the sections and knuckle. This process can involve trimming away a portion of the knuckle and polishing the sections to meet a desired aesthetic appeal. 
     It should be understood that the processes described above are merely illustrative. Any of the steps may be removed, modified, or combined, and any additional steps may be added or steps may be performed in different orders, without departing from the scope of the invention. 
     The described embodiments of the invention are presented for the purpose of illustration and not of limitation.
