CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application claims the benefit under 35 U.S.C. 119(e) of U.S. Prov. Pat. Appl. No. 61/832,704, entitled MODULAR STRUCTURAL STIFFENERS filed on Jun. 7, 2013, the content of which is incorporated herein by reference in its entirety. 
    
    
     FIELD OF THE DESCRIBED EMBODIMENTS 
     The described embodiments relate generally to personal electronic devices and more particularly to internal structural members and subassemblies of the same. 
     BACKGROUND 
     Generally, personal electronic devices take a plurality of forms and are manufactured using available materials which provide a balance of durability and function. Many electronic devices include a plurality of internal components that are assembled into a functional unit to which a housing is “snapped” over. For example, devices having plastic housings or covers are typically formed as standalone devices absent a housing, and after testing and/or inspection, have a flexible or relatively flexible plastic housing applied thereon. 
     However, depending upon the internal components, structural members, frames, composition of the housing, and other aspects of a finished device, application of the housing after internal assembly can cause warping of edges of the housing (e.g., while snapping the housing over components), cosmetic defects (e.g., deflection, discoloration, and/or chipping of decorations/cosmetic surfaces), and in some cases breaking of the housing or internal components. 
     Therefore, what is desired are innovations in device structures and assembly methodologies which overcome these and other drawbacks. 
     SUMMARY OF THE DESCRIBED EMBODIMENTS

     DETAILED DESCRIPTION OF SELECTED EMBODIMENTS 
     Representative applications of methods and apparatus according to the present application are described in this section. These examples are being provided solely to add context and aid in the understanding of the described embodiments. It will thus be apparent to one skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the described embodiments. Other applications are possible, such that the following examples should not be taken as limiting. 
     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 described embodiments relate generally to personal electronic devices and more particularly to internal structural members and subassemblies of the same. According to exemplary embodiments, internal structural members of a personal electronic device may be divided into structural and/or functional subassemblies that are assembled into a housing cavity, rather than the alternative. By assembling subassemblies into the housing cavity, stress on housings made from less rigid materials (e.g., plastic) may be reduced, resulting in better cosmetic qualities than conventional assembly methodologies. Furthermore, by assembling subassemblies into the housing, exacting tolerances may be maintained through adjustable joints which allow alignment of individual subassemblies according to external features of the housing (e.g., button features, switch features, charging port features, etc.) and also allow alignment between adjacent subassemblies. 
     According to at least one exemplary embodiment, a device housing is formed of plastic and an associated modular subassembly is formed of metal. In one configuration, the associated modular subassembly is comprised of a plurality of “puzzle” parts that are initially separate from one another and configured to be joined together within the device housing in a specific manner. Thus, at least a portion of the associated modular subassembly may function as a support member, and can further function as an active or passive electrical component such as an antenna. Other subassemblies may function to provide mechanical stiffness for interaction with input devices such as switches and buttons. Hereinafter exemplary embodiments of the present invention are described in detail. 
       FIG. 1A  is a perspective view of a housing  100  for a personal electronic device, according to an exemplary embodiment. The housing  100  may be a housing for a cellular telephone, media player, tablet computer, or any other personal electronic device. The housing  100  may be formed of plastic in some embodiments. According to at least one embodiment, the housing  100  is formed of acrylonitrile butadiene styrene (ABS) plastic or a functionally equivalent plastic material. 
     The housing  100  may have an external surface  101  and an internal cavity  102  defined therein. The internal cavity  102  may be sized to accommodate modular subassemblies as described herein for assembling a personal electronic device. The external surface  101  may be a cosmetic surface and/or peripheral surface surrounding the internal cavity  102 . Furthermore, the external surface  101  may include a plurality of external features  103 ,  104  defined thereon. The external features  103 ,  104  may be features for integrating input/output devices or other systems. According to one embodiment, the external features  103 ,  104  include button features, switch features, charging port features, audio port features, memory slot features, subscriber identity module (SIM) card receiving features, and/or any other feasible features. 
       FIG. 1B  is an alternate perspective view of the housing  100  of  FIG. 1A . As shown, the housing  100  may further include a back surface  105  opposite the internal cavity  102  and adjacent the external surface  101 . As further shown, features  103 ,  104  may exist on any portion of the surfaces of the housing  100 . 
       FIG. 2  is an exploded view of modular subassemblies  200  (e.g., a system of modular subassemblies) of a personal electronic device, according to an exemplary embodiment. As illustrated, the subassemblies  200  may include a plurality of members arranged to be received within housing  100 . The subassemblies  200  may include at least two separate members  201  and  203 , according to one embodiment. According to another embodiment, the modular subassemblies  200  may include at least two separate members  201  and  205 . 
     Generally, subassembly  201  may be a chassis arranged to be affixed to an interior surface of the cavity  102 . The chassis  201  may be formed of relatively stiff material such as, for example, stainless steel, steel, aluminum, or any other suitable material. The chassis  201  may be substantially planar and/or substantially rectangular. The chassis  201  may also function as a ground plane for an end device. The chassis  201  may be affixed to the housing  100  through an adhesive member  202 . The adhesive member  202  may be a pressure sensitive adhesive member in one embodiment. 
     The modular subassembly  203  may be a side support member arranged to be affixed to an interior surface of the internal cavity  102  opposite the external surface  101 . The side support member  203  may be formed of relatively stiff material such as, for example, stainless steel, steel, aluminum, or any other suitable material. 
     The modular subassembly  205  may be a corner support member arranged to be affixed proximate an internal corner of the internal cavity  102  opposite the external surface  101 . The corner support member  205  may be formed of relatively stiff material such as, for example, stainless steel, steel, aluminum, or any other suitable material. 
     The support members  203 ,  205  may be joined with a joining member  204  to establish an L-shape that conforms to the internal bottom-left corner of the internal cavity  102  (where similar L-shapes are established to conform to the other internal corners of the internal cavity  102 ). According to one embodiment, the joining member  204  is an insert molded plastic member affixed to both support members  203 ,  205  and keeping the same a relatively fixed, predetermined distance apart. 
     The modular subassemblies  200  may further include a spanning member  206  arranged to span between corner support members  205 ,  208  and align with feature  104 . The spanning member is arranged to be affixed to an interior surface of the internal cavity  102  opposite the external surface  101 . The corner support member  208  may be relatively similar in function to corner support member  205 . 
     The modular subassemblies  200  may further include side support member  210  arranged to be joined to corner support member  208  through joining member  209 . Side support member  210  may be relatively similar in function to support member  203 . Furthermore, joining member  209  may be relatively similar to joining member  204 . 
     Generally, members  203 - 210  may form a bottom portion of the subassemblies  200 , and may be arranged to be inserted and affixed to housing  100  after alignment/registration with any associated features  103 ,  104 . As further illustrated, modular subassemblies  200  further include members  211 - 216  which are arranged to form a top portion of the subassemblies  200 , and may be arranged to be inserted and affixed to housing  100  after alignment/registration with any associated features  103 ,  104 . For example, side support member  211  is arranged to be joined with corner support member  213  through joining member  212 . Furthermore, corner support member  215  is arranged to be joined with side support member  214  through joining member  216 . Hence, in the embodiment illustrated in  FIG. 2 , the modular subassemblies  200  include nine main components (i.e., members  203 ,  205 ,  206 ,  208 ,  210 ,  211 ,  213 ,  214 , and  215 ) that are joined to one another via four sub-components (i.e., joining members  204 ,  209 ,  212 , and  216 ). As noted above, the modular subassemblies  200 , when joined to one another via the joining members, can be utilized as an antenna for enabling the end device to transmit and receive wireless signals. 
     It is noted that although a particular number of side support members and corner support members have been illustrated, the same may be varied to include more or less individual members according to any desired implementation of exemplary embodiments. It is further noted that the subassemblies  200  may each be formed of steel, stainless, steel, aluminum, or any other suitable material. According to at least one embodiment, individual subassemblies of the subassemblies  200  are formed of sheet metal or stainless steel sheet metal. 
     As noted above, several different corner members may be joined to side support members through joining members. These joining members  204 ,  209 ,  212 , and  216  may be formed in an insert molding process such that each joining member is an insert molded plastic member affixed to both adjacent support members  203 ,  205 ;  208 ,  210 ;  211 ,  213 ; and  214 ,  215 , respectively, and keeping the same a relatively fixed, predetermined distance apart (e.g., see  FIG. 7 ). The joining members  204 ,  209 ,  212 , and  216  may be formed of plastic and/or a dielectric. 
     Upon joining, the joined members, the spanning member  206 , and the chassis  201  may be aligned/registered and inserted/affixed to the housing  100 . For example,  FIG. 3  is a plan view of the housing  100  with affixed modular subassemblies  200 , according to an exemplary embodiment. 
     As shown, the joined members  214 ,  215  may be aligned with associated features  103  and inserted in the housing  100 . Furthermore, joined members  208 ,  210  may be aligned with associated features  103  and inserted in the housing  100 . Even further, spanning member  206  may be aligned with associated features  104  and inserted into the housing  100 . Moreover, joined members  211 ,  213  and  203 ,  205  may be further aligned and inserted in the housing  100 . Although not particularly illustrated, it is understood that alignment for these members may be relative to features  103 ,  104  or according to other features of the housing  100 . Therefore, the housing  100  itself acts as an assembly/datum fixture for registering/aligning the subassemblies  200 . 
     Each of the members  203 - 216  may be affixed to an interior surface of the interior cavity  102  of the housing  100  using, for example, an adhesive or glue. The adhesive or glue may include any suitable adhesive chemistry, including pressure sensitive, heat sensitive, or any other feasible chemistry. 
     Upon affixing the members  203 - 216 , the chassis  201  may be aligned/registered with the housing  100  and inserted into the same adjacent to internal edges of the members  203 - 216 . Adhesive member  202  is not illustrated here for clarity. For example, one or more optical fiducial markers or other alignment features  131  may be present on the chassis  201 . The alignment features  131  may include a coordinate point/axis, screw hole, welded stud, welded nut, pin hole, or any other suitable feature. Using a relative location of the alignment features  131  as compared to features  103 ,  104  of the housing  100 , the chassis  201  may be aligned. 
     Thereafter, the individual members  201 - 216  may be fastened to one another, for example, through welding (e.g., laser welding). Fastening joints  301 ,  302 ,  303 ,  305 , and  306  are illustrated. According to one embodiment, the fastening joints  301 ,  302 ,  303 ,  305  and  306  comprise lap joints for ease in aligning and registering adjacent members. Furthermore, as shown, joints  305  and  306  are generally out of alignment. This may enhance the structural integrity of an end device. However, according to some embodiments, joints  305  and  306  may generally be aligned. As further shown, spanning member separates joints  302 ,  303  from a centerline formed at joint  301 . This may also enhance the structural integrity of an end device. However, according to some embodiments spanning member  206  may instead be omitted. Hereinafter, expanded, detailed views of the annotated portions of  FIG. 3  are described in detail with reference to  FIGS. 4-7 . 
       FIG. 4  is an expanded view of a fastening joint of a modular subassembly, according to an exemplary embodiment. As illustrated, a peripheral edge  402  of the chassis  201  may be welded or otherwise fastened (e.g., through screws, glue, etc.) to an interior edge  405  of an adjacent support member (illustrated as  214 ). The weld pool  401  may penetrate the edge  402  but not the edge  405  such that the housing  100  is not deformed or damaged. This may be accomplished through modulation or change to a laser intensity and/or duration, or by any other feasible manipulation of a welding system. As further shown, a thickness of an interior portion  403  of the chassis  201  is generally greater than that of the edge  402 . Therefore, a good weld may be formed without burning through member  214 . It is noted that similar fastening welds may be formed between chassis  201  and members  203 ,  210 , and  211 . 
       FIG. 5  is an expanded view of a fastening joint of a modular subassembly, according to an exemplary embodiment. As illustrated, joint  301  (and similarly, joints  302 ,  303 ,  305 , and  306 ) is a lap joint allowing for contraction or expansion of areas  505  for appropriate alignment of individual members within the housing  100 . Upon proper alignment, the adjacent members may be welded to one another through, for example, laser welding and formation of weld pool  501 . As shown, weld pool  501  only fully penetrates an interior portion of the lap joint, thereby avoiding damage to the housing  100 . 
       FIG. 6  is an expanded view of an interface between a modular subassembly and housing, according to an exemplary embodiment. As noted above, individual side and corner support members may be adhered to an interior surface of the interior cavity  102  of the housing  100 . For example, glue  601  may be applied to either or both of the housing  100  and the associated support members (shown as  214 ). Upon appropriate alignment, a spring loaded clip or biasing member  602  may gently maintain alignment while glue or adhesive  601  is allowed to cure. Upon curing (or upon curing and welding as described above), the biasing member  602  may be removed. It is noted that although only a single biasing member  602  is illustrated, a plurality of separate biasing members  602  may be used in actual implementation, for example, by clipping around a periphery of the housing  100  while glue or adhesive is allowed to cure. 
     As described above with reference to  FIG. 2 , joining members such as member  212  may be insert molded about two adjacent support members (e.g., a side support and corner support).  FIG. 7  is an expanded view of an interface between modular subassemblies, according to an exemplary embodiment. As shown, the joining member  212  is insert molded about corner member  213  and side member  211  and maintains the same at a relatively fixed predetermined distance of D A . According to one embodiment, the distance D A  is an antenna gap to allow an appropriate capacitance between distal end  701  of corner support member  213  and distal end  702  of side support member  211 , for example, if members  213  and  215  are to be used as an antenna. The distance D A  may be altered according to any desired implementation. Furthermore, the distance D A  may be changed, minimized, or maximized if member  213 ,  215  are not used as a portion of an antenna. Joining members  204 ,  209 , and  216  may be formed similar to member  212 , and therefore members  215 ,  205 ,  206 , and  208  may also be used as a portion of an antenna in some embodiments. 
     As described above with reference to  FIGS. 4-5 , laser welds may be used to fasten adjacent subassembly members in some embodiments. However, welding may provide a significant source of heat which may damage a housing formed of, for example, plastic.  FIG. 8  depicts an example fastening path for fastening modular subassemblies, according to an exemplary embodiment. As illustrated in  FIG. 8 , individual weld joints  1 ,  2 ,  3 ,  4  may be performed in succession at disparate portions of the illustrated structure to reduce localized heat buildup which would otherwise damage and/or warp housing  100 . For example, one weld path may follow arrows A 1 , A 2 , and A 3  in iterative succession in a clockwise manner (continued as joints  5 ,  6 ,  7 ,  8 , etc.). The same may be altered or reversed in some embodiments. Still in other embodiments a time delay or other cooling mechanism may be included to reduce localized heat accumulation. 
     Upon fastening of the modular subassemblies  200  within the housing  100 , the chassis and housing may be populated with device components and/or logic boards  901 .  FIG. 9  is a schematic of a partially assembled personal electronic device  900 , according to an exemplary embodiment. In device  900 , the logic board  901 , may for example, be mounted relative to the alignment feature(s)  131  to ensure proper placement with regards to external features of the housing  100 . For example, features  103  may include switches, buttons or other input/output devices mechanically and/or electrically connected to the logic board  901 . Features  104  may include charging ports, audio ports, or other features mechanically and/or electrically connected to the logic board  901 . Moreover, corner support members  205 ,  208  and spanning member  206  (which may be welded and therefore in electrical communication) may be interfaced with logic board  901  as an antenna. Similarly, corner support members  213  and  215  (which may also be welded) may be interfaced with logic board  901  as an antenna as well. 
       FIG. 10  is a flowchart of a method  1000  of assembling a personal electronic device, according to an exemplary embodiment. The method  1000  includes forming a housing at step  1001 . The forming may include molding or otherwise forming a housing (e.g.,  100 ) from plastic. The housing may be painted, decorated, polished, and/or sealed with a clear coat in some embodiments. 
     Thereafter, the method  1000  includes joining corner subassemblies at step  1002 . In some embodiments, steps  1001  and  1002  may be reversed or may be performed substantially in parallel. The joining may include insert molding joining members between corner assemblies and associated side support members as described above. Thereafter, the method  1000  includes aligning and inserting corner and spanning subassemblies into the formed housing at step  1003 . The aligning and inserting may be performed as described above. 
     Thereafter, the method  1000  includes joining the subassemblies to the housing at step  1004 . For example, spring loaded clips or biasing members may be used to hold the inserted subassemblies until an adhesive or glue cures. Thereafter, or at substantially the same time, the chassis may be aligned and inserted into the housing at step  1005 . 
     The chassis may then be joined to the subassemblies at step  1006 , for example, through laser welding, screws, bolts, adhesives, or any suitable manner of fastening. As previously described herein, the chassis (e.g., the chassis  201 ) can function as a ground plane within the end device. In this manner, the subassemblies can be grounded via the joining technique (e.g., welding) used to join the subassemblies to the chassis at step  1006 . If welding, the welding process may be adjusted to reduce or minimize accumulation of heat proximate the housing. In this manner, distortion and damage to the housing may be minimized. After joining, at step  1007 , the chassis and housing may be populated with device components such as, for example, input/output interfaces, logic boards, power supplies/batteries, transceiver circuitry, and/or other suitable components. 
     One or more subassemblies may then, at step  1008 , be interconnected with the populated device components. For example, one or more corner subassemblies may be interconnected such that they may function as antennas or as electronic components for an end device. Finally, at step  1010 , the end device can utilize the joined subassemblies as an antenna to facilitate wireless communication, e.g., with a base station.
