Description:
FIELD OF THE DESCRIBED EMBODIMENTS 
     The described embodiments relate generally to hinges, and more particularly, to coaxial hinge apparatuses useable in clutch assemblies. 
     BACKGROUND 
     Hinges for personal electronic devices typically provide a flexible attachment point allowing for operation of features intended to open and close, for example, lids or other panels. Furthermore, lids or other panels provide for unique mounting points for antenna and other communication components. 
     However, signal cables, including coaxial cables, necessary for communication with antennas in some circumstances may require crimped or fixedly attached connectors which may not allow for easy routing. For example, the crimped or fixedly attached connectors may be bulkier than the cables, and may not necessarily be routed without removal and re-crimping. Furthermore, crimping of connectors onto routed signal cables may be exceedingly difficult in scenarios where space is limited.

     DETAILED DESCRIPTION OF SELECTED EMBODIMENTS 
     Representative applications of methods and apparatuses 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. 
     As described herein, hinge apparatuses are provided which allow for a hinge to be assembled around terminated cables or cabling without removing crimped connectors. Such hinges may be useable in clutch assemblies of personal electronic devices. 
       FIG. 1  depicts a front facing perspective view of a personal electronic device  100  in an open (lid) state. Device  100  can include base portion  102  formed of bottom case  104  fastened to top case  106 . Base portion  102  can be pivotably connected to lid portion  108  by way of clutch assembly  110  hidden from view by a cosmetic wall. Base portion  102  can have an overall uniform shape sized to accommodate clutch assembly  110  and inset portion  112  suitable for assisting a user in lifting lid portion  108  by, for example, a finger. Top case  106  can be configured to accommodate various user input devices such as keyboard  114  and touchpad  116 . Keyboard  114  can include a plurality of low profile keycap assemblies each having an associated key pad. 
     Lid portion  108  can be moved with the aid of clutch assembly  110  from the closed position to remain in the open position and back again. Lid portion  108  can include display  120  and rear cover that can add a cosmetic finish to lid portion  108  and also provide structural support to at least display  120 . The clutch assembly  110  may provide a resistive or biasing force suitable for supporting the display  120  and lid portion  108  in an open or closed position through the use of at least two interlocking and/or engaging portions, which are described more fully below with reference to  FIGS. 2-6 . 
       FIG. 2  is a perspective view of a hinge apparatus  200 , according to an embodiment of the invention. The hinge apparatus  200  may be used to form at least a portion of the clutch assembly  110 . As shown, the apparatus  200  includes a first portion  201  configured to engage with a second portion  202 . Furthermore, an inner cylindrical cavity  211  is defined therein providing for a route to pass cabling or other items. 
     The first portion  201  may rotate about the Y′ axis relative to the second portion  202 , and vice versa. For example, rotation of one or both of the first ( 201 ) and second ( 202 ) portions may not disturb the inner cylindrical cavity  211 . Therefore, the inner cylindrical cavity may be appropriate for stable routing of cables for a final device assembly process. 
     Hereinafter, a more detailed description of the first and second portions  201  and  202  of the apparatus  200  is provided. 
       FIG. 3  is a perspective view of the first portion  201  of the hinge apparatus  200 . As illustrated, the first portion  201  includes a cylindrical housing  216  fixedly coupled to a first base member  212 . The cylindrical housing  216  is configured to engage within a complementary cylindrical housing of the second portion  202  illustrated in  FIG. 2 , and therefore, the cylindrical housing  216  may be termed an inner cylindrical housing and/or an inner cylindrical member. 
     The cylindrical housing  216  may include an outer cylindrical surface  217  with a generally longitudinal slot  210  formed therethrough. Generally, the outer cylindrical surface  217  may have a circumference sized to engage with an inner cavity of the second portion  202  of the apparatus  200 . The slot  210  extends from a first distal end  214  of the cylindrical housing  216  to a second distal end  215  of the cylindrical housing  216 . The slot  210  may form a first path along its length, and may have a width suitable for passing a cable or cables from exterior of the cylindrical housing  216  to the inner cylindrical cavity  211 . Routed cable or cabling may rest on a semi-circular notch or cutout  213  formed in the base member  212 . 
     The base member  212  may be fixedly attached to the bottom portion  106  of the device  100  in some embodiments, or may alternatively be fixedly attached to the lid portion  108 . Attachment may be facilitated through the use of adhesives, welding, fasteners (e.g., screws, bolts), or other suitable forms of attachment. The base member  212  may be sized allow for relatively stable attachment, and may take forms other than the generally rectangular form illustrated. 
     Turning to  FIG. 4 , an elevation view of the first portion  201  is illustrated. As shown, the slot  210  extends between distal ends  214  and  215 . Furthermore, the slot  210  allows for passing of cable therethrough to the inner cylindrical cavity  211 . 
       FIG. 5  is a perspective view of the second portion  202  of the hinge apparatus  200 . As illustrated, the second portion  202  includes a cylindrical housing  226  fixedly coupled to a second base member  222 . The cylindrical housing  226  is configured to engage about a complementary cylindrical housing  216  of the first portion  201 , and therefore, the cylindrical housing  226  may be termed an outer cylindrical housing and/or an outer cylindrical member. 
     The cylindrical housing  226  may include an outer cylindrical surface  227  with a generally longitudinal slot  220  formed therethrough. The slot  220  extends from a first distal end  224  of the cylindrical housing  226  to a second distal end  225  of the cylindrical housing  226 . The slot  220  may form a second path along its length, and may have a width suitable for passing a cable or cables from exterior of the cylindrical housing  226  to a second inner cylindrical cavity  221 . The second inner cylindrical cavity  221  may have an inner cylindrical surface and a circumference sized to engage with the outer surface  217  of the first member  201 . 
     For example, with reference to both  FIGS. 3 and 5 , the circumference of the second inner cylindrical cavity  221  may be slightly smaller than the circumference of the outer surface  217 . Therefore, upon engagement, biasing forces created by expansion of the inner cylindrical cavity  221  and constriction of the inner cylindrical cavity  211  provide for a clutch-like action. Furthermore, clutch-like properties of the cylindrical surface within the inner cavity  221  and/or the outer surface  217  of the first portion  201  may be coated or treated to promote clutch-like action. Generally, if used as a hinge in a clutch assembly for a personal electronic device, clutch-like action and/or properties may include a coefficient of static friction greater than a coefficient of kinetic friction such that a lid supported with the hinge would be supported stably in an open or closed position, but still allow for repositioning. 
     Turning back to  FIG. 5 , the base member  222  may be fixedly attached to the bottom portion  106  of the device  100  in some embodiments, or may alternatively be fixedly attached to the lid portion  108 . Attachment may be facilitated through the use of adhesives, welding, fasteners (e.g., screws, bolts), or other suitable forms of attachment. The base member  222  may be sized allow for relatively stable attachment, and may take forms other than the generally rectangular form illustrated. 
     Turning to  FIG. 6 , an elevation view of the second portion  202  is illustrated. As shown, the slot  220  extends between distal ends  224  and  225 . Furthermore, the slot  220  allows for passing of cable therethrough to the second inner cylindrical cavity  221 . 
     Hereinafter, engagement of the first and second portions  201  and  202  is described more fully with reference to  FIGS. 7-8 . 
       FIG. 7  is a diagram depicting engagement of the first and second portions of the hinge apparatus  200  of  FIG. 2 . As shown, the distal end  215  of the cylindrical housing  216  may be engaged with the second inner cavity  221  of the second portion  202  at the distal end  224 . To facilitate engagement, the cylindrical housing  216  may be constricted through use of at least two dies applied to the distal end  215 . The dies may be any suitable dies, including dies configured to compress a spring-like cylindrical member  216  to reduce its outer circumference. Alternatively, or in combination, the relative size of the cavity  221  may be increased. For example, the slot  220  may be temporarily widened through use of a deflection member inserted therein. The deflection member or tool may be a generally slotted tool somewhat similar to a slotted screw driver. The tool may be turned to increase the width of the slot  220 , thereby increasing an overall volume of the cavity  220  to facilitate engagement of the first and second portions. Upon engagement, the dies and/or tool may be removed to form the apparatus as illustrated in  FIG. 2 . 
     As described above, the slots  210  and  220  form unique paths which should not completely align during rotation of one or both of the first and second portions  201  and  202 . For example,  FIG. 8  is a diagram depicting the unique paths of the slots  210  and  220 . As shown, there exists an angle θ between each slot such that rotation about the Y′ axis will not allow complete alignment of both slots  210  and  220 . Therefore, the first and second slots form unique paths which prevent the at least one cable to pass through the first and second slots simultaneously (e.g., while the hinge apparatus is assembled). The angle θ may be a fixed value throughout rotation, or may change depending upon the arrangement of the slots. The paths may be generally linear, helical, or any combination of both. Furthermore, the slots  210  and  220  may be formed in a spiraling counter rotational fashion. According to one embodiment, the first slot  210  is a linear slot along a first linear path, the second slot  220  is a linear slot along a second linear path, and the first and second linear paths are arranged at an angle to one another. The angle, in this particular scenario, would be a constant angle. According to another embodiment, the first slot is a helical slot along a first helical path and the second slot is a helical slot along a second helical path crossing the first helical path. In this particular scenario, the helical paths would not align due to the second helical path crossing the first. 
     Additionally, one of the slots may be generally linear, while the other is linear, helical, spiral, or otherwise formed. Therefore, exhaustive description of every permutation of slot arrangements is omitted herein for the sake of brevity. 
     The lack of alignment of the slots allows for stable routing of a cable, cabling, or other member within the hinge apparatus while preventing the same from otherwise falling out. For example,  FIG. 9  is an exploded perspective view of the hinge apparatus  200  with cabling routed therein. As shown, cabling  903  may include terminal ends  902  and  904 . Terminal end  902  may be coupled to an electrical component or printed circuit board (PCB)  901 , and therefore, would not allow routing directly through a cylindrical cavity smaller than the PCB  901 . Terminal end  904  may further have a profile inhibitive of directly routing through a cylindrical cavity. 
     However, as illustrated, the cabling  903  may be routed through each of slots  210  and  220  successively, and subsequent engagement of the first portion  201  and the second portion  202  may be facilitated. Therefore, a fully operational hinge apparatus with cabling routed therein may be formed and used in final device assembly. 
       FIG. 10  is a flowchart of a method  1000  of assembling a hinge apparatus  200 , according to an embodiment of the invention. As shown, the method  1000  includes routing one or more cables or cabling through a slot formed in an inner cylindrical housing at block  1001 . For example, the inner cylindrical housing may be similar to housing  216  illustrated in  FIG. 3 . Thereafter, the method  1000  includes routing one or more cables or cabling through an outer cylindrical housing at block  1002 . For example, the outer cylindrical housing may be similar to housing  226  of  FIG. 5 . 
     It is noted that blocks  1001  and  1002  may be alternated in order without departing from the scope of embodiments of the invention. 
     Upon successful routing of the cable or cabling, the method  1000  includes engaging the inner and outer cylindrical housings to form a hinge assembly or apparatus at block  1003 . The engaging may be facilitated through use of a set of dies and/or a deflection tool as described above with reference to  FIG. 7 . 
     The formed assembly may then be attached to a personal electronic device at block  1004 . For example, a base member associated with the inner cylindrical housing may be attached to a first portion of a personal electronic device such as bottom panel  106  of  FIG. 1 . Further, the base member associated with the outer cylindrical housing may be attached to a second portion of the personal electronic device such as lid  108  of  FIG. 1 . The attached hinge apparatus would subsequently function as a hinge or clutch, with cabling routed therein. One or more terminal ends of the routed cable or cabling may then be attached to associated electronic components to establish operative communication therebetween.
