     FIELD OF INVENTION 
     This invention relates generally to accessory mounts and more specifically to those mounts intended for attachment to headwear. 
     BACKGROUND OF THE INVENTION 
     The deployment of a headlamp positioned in the vicinity of a user&#39;s forehead is a long-known technique to provide hands free lighting when needed. One technique for deploying such hands-free lighting is to attach a headlamp to elastic bands that can circumscribe a user&#39;s head or helmet. An exemplary prior art accessory mounting band is shown in  FIG. 11A . The elastic bands retain the light or lamp against the forehead while the user engages in a desired activity. This elastic band technique has also been used for deploying small, point-of-view cameras, such as the Go-Pro brand camera, on a user&#39;s head, hat or helmet. Many users eschew the elastic band mounts because of a variety of reasons, including vanity and discomfort. 
     Other techniques for deploying an accessory such as a light or point of view (“POV”) camera involve attaching a mounting apparatus that is adapted to receive the light or camera to a baseball cap. The currently available mounts intended to attach to a baseball cap come in a variety of structural configurations. They all, however, suffer from a wide array of deficiencies. For example, one style of mount requires that the brim or bill of the hat be pierced. This prior art technique is shown in  FIG. 11B . In this style mount, the accessory-receiving portion of the mount attaches to a post that pierces through the hat&#39;s brim. This type mount is undesirable because it physically deforms the subject cap in permanent fashion. Also, the hole through which the post is pierced can loosen with time, causing the mount to undesirably shake and wobble. 
     Other accessory mounts intended for attachment to the brim of a hat are known as well. Some mounts use an alligator clip arrangement that clips to the bill of a cap. With this type of mount, the alligator clip slides over the front of the cap bill and holds an accessory device either above or below the bill. An example of this prior art device is shown in  FIG. 11C . The prototypical alligator clip is formed from two panels that are connected by a metal spring. The spring is positioned between the two panels and near one end of them. The interpositioned spring biases the panels so that their ends opposite the spring are forced into contact with each other. The inner surfaces of the panels are serrated in some form, assumedly on the assumption that such serration enhances the ability of the clip to grip whatever structure (e.g., cap bill) inserted between the two panels. Alligator clip mounts have several deficiencies which make their performance less than desirable for use with accessory devices. In one instance, the alligator clip is bulky and its portion that is positioned underneath the bill will provide a visual distraction or obstruction. Secondly, this type of clip focuses its gripping force and brim contacting surfaces at one end of the clip—the end not localized at the cap brim edge. As a result, alligator clip type mounts do not provide sufficient grip to keep a heavier device like a POV camera in place when the user is involved in any type of vigorous activity. During such activity the clip tends to slide transversely along the brim front causing the camera angle to change. 
     Some bill accessory mounts utilize as their bill attachment mechanism a molded plastic clip or formed metal clip. In contrast to the alligator clip mount that uses the force of a metal spring to urge the panels to a point of contact, this type of clip eschews the metal spring in favor of integrally molded or formed rigid panels resiliently connected at a meeting point. The clip attaches to a cap bill simply by pushing the cap bill between the clip&#39;s panels. Examples of this type of prior art mounting clip are shown in  FIGS. 11D-11G . These types of clips are intended to hold onto the cap bill through some level of friction between the clip panels and the inserted bill. At best, these slip-on plastic or metal mounting clips work well with small, lightweight devices, like mini-LED lights, that mount below the brim of a cap ( FIG. 11D ). The currently available versions do not work well with heavier devices like POV cameras. In this respect the clips tend to slide across and off the cap bill because they: a) do not create enough clamping force with the bill; b) do not provide for sufficient frictional contact with the bill; or both. As a result, a user deploying one of the molded plastic or formed metal clips must restrict and monitor his or her physical movements so as not to move too violently and cause the POV camera to move or fall off the cap. 
     SUMMARY OF THE INVENTION 
     The preferred embodiment clip overcomes the deficits of the prior art and allows for the secure mounting of accessory devices on a hat brim. The device works particularly well when used to mount accessories on the brim (a/k/a bill) of a baseball cap. Such a brim typically has a front edge that has an edge (“front-to-back”) curvature of certain radius. The brim also has a thickness. The brim also has a transverse curvature (also known as a “bend”) of a certain radius. The preferred embodiment clip adapted for attachment to such a brim comprises a first (top) panel and a second (bottom) panel. The first and second panels respectively have a length, a width, a top surface, a bottom surface, a proximal end and a distal end. 
     The first panel and second panel each resiliently connect at their distal ends in general perpendicular fashion to a nose segment. The top of the nose segment is connected to the distal end of the first panel. The bottom of the nose segment is connected to the distal end of the second panel. The nose segment has a front-facing (outer) surface and a brim-facing (inner) surface. The top (outer) surface of the first panel includes mounting structure adapted (sized and shaped) to receive an accessory device such as a light or POV camera. This mounting structure is positioned on the first panel at the proximal end to ergonomically balance the mounted accessory. 
     Importantly and in contra-distinction to the prior art, the second panel has a wedge-shaped portion in which the width of the panel increases from the distal end of the panel to the proximal end of the panel. This allows the bottom of the clip to cut into and frictionally engage the bottom of the hat brim due to the transverse radius of the hat brim. This frictional engagement increases the purchase of the clip against the hat brim. 
     Also adding to the friction-creating contact between the preferred embodiment clip and hat brim is the fact that the clip has a plurality of convex and concave surfaces. For example, in the preferred embodiment, the bottom (inner) surface of the first panel is concave. This concavity has a radius closely equal to that of the transverse curvature of the brim. This allows for increased surface contact with the top of the hat brim and hence an increased frictional hold. A second friction augmenting feature is the shape of the second panel. In this respect, the top surface of the second panel is convex. The convexity has a radius closely equal to that of the transverse curvature of the brim. A third friction augmenting feature is built into the nose segment, which in the preferred embodiment has a plurality of concave surfaces that can mirror both the edge curvature and transverse curvature of the typical baseball cap. For example, in the preferred embodiment, the intermediate brim-facing surface of the nose segment is concave and the concavity closely approximates that of the edge curvature of the hat brim. Additionally, at the distal end of the second panel, the top surface of the second panel includes a channel. This channel too can have a convex floor and sidewall. This channel serves to gather the stitched border of fabric that is found on the undersurface of the brim about the brim&#39;s perimeter. By receiving this fabric, the brim-holding ability of the clip is enhanced. 
     The design of the inventive clip also has beneficial application as the foundation for a clip or clip system that allows for interchangeable attachment of end-pieces that can accommodate a variety of device mounting structures. This is done via an inventive system in which a clip body meeting the design of the above-described clip includes at its proximal end structure to releasably engage interchangeable end-pieces that each include a different accessory device mounting support. The system thus could include a plurality of end-pieces each directed to an accessory device having a different type of mounting structure. The system could also include a plurality of end-pieces directed to the same accessory (i.e., the same accessory mounting structure), but each end-piece has mounting structure of different physical characteristics, such as tall, short, offset to the left or offset to the right. In another embodiment, the design of the present invention clip and systems using a similarly structured clip body can be adapted to include a mount for holding a microphone or microphone jack (collectively referred to as a “microphone/jack”). The invention is also directed to an inventive system in which a clip body meeting the design of the above described clip releasably engages an insert that can be used to reduce the vertical spacing between the top and bottom panels of the clip body to allow the clip body to be used on brims of varying thicknesses. The system can include one or more interchangeable inserts of varying thicknesses, textures and size. 
     The design of the inventive clip, system and clip body described above (including those using the mentioned insert) also has beneficial application as the foundation for a wearable personal communication device. In this respect the novel brim holding design of the clip and clip body allows for the deployment of a communication system (preferably a Bluetooth device) on the second panel and, thus, directly under the hat brim in a key location for the user. In contrast to prior art devices, this assures a great user experience because both the speaker and microphone are in ideal positions for use when speaking and listening. Currently available Bluetooth wearable devices come in the form of body mounts, collars, earbuds, headphones, stocking caps or baseball caps with speakers attached. All of these have deficits, the particular one being that the speakers and microphones are not positioned at a location beneficial to the user&#39;s mouth and ears. The brim clip with incorporated communication system positions the microphone and speakers in close proximity to the mouth and ears without obstruction. 
     In the preferred embodiment, the communication system includes dual speakers that point and project to the ears of the user. Additionally, the microphone is directly in place for conversation. No electronic devices directly touch the skin. Furthermore, no audio waves are projected directly into the ear canal as with earbuds. This is because there is no physical structure lodged in the ear canal of the user. Nor is there any electronic componetry adjacent to the ear structure. This results in a user&#39;s awareness not being diminished due to the blocking of environmental noise. The inventive clip and clip body will have beneficial application among exercise and outdoor enthusiasts, such as runners, walkers, hikers and fishermen. Users are now able to have hands-free Bluetooth or similar connectivity to their mobile devices without having to use earbuds, headphones or neck collars. 
     In a first main embodiment the communication enabling clip includes a first panel and a second panel as described above in terms of the basic inventive clip. The first and second panels thus have a length, width, top surface, bottom surface, proximal end and distal end. The panels are each resiliently connected at their distal ends to a nose segment. The second panel has the wedge-shaped portion in which the width of the wedge-shaped portion increases from the distal end of the panel toward the proximal end of the panel. As described above for the basic clip and clip body, the bottom surface of the first panel can be concave, the top surface of the second panel can be convex. For purposes of enabling communication with a user&#39;s mobile device the second panel further includes a communication system that, in a preferred embodiment has one or more speakers, a control interface, a microprocessor; a wireless communication module connected to the microprocessor and a battery. The battery is preferably rechargeable and connected to a charging interface. The top surface of the first panel at the proximal end of the first panel can have structure adapted for receiving an accessory device. Non-limiting examples of accessory devices include a camera, a headlamp or a strobe. 
     In an alternate preferred embodiment, the invention is directed to the above described clip body with an included communication system effecting communications with a user&#39;s mobile device. The clip body comprises a first panel and a second panel. The first and second panels respectively have a length, width, top surface, bottom surface, proximal end and distal end. The first panel and second panel are each resiliently connected at their distal ends to a nose segment. The nose segment has a front-facing surface and a brim-facing surface. The second panel has a wedge shaped portion in which the width of the panel increases from the distal end of the panel to the proximal end of the panel. For purposes of enabling communications, the second panel further includes a communication system that can communicate with a mobile device. That communication system includes one or more speakers, a control interface, a microprocessor; a wireless communication module connected to the microprocessor and a battery. The battery is preferably connected to a charging interface. As described above for the basic clip and clip body the bottom surface of the first panel can be concave and the top surface of the second panel can be convex. The top surface of the second panel can be texturized to increase purchasing grip. The proximal end of the first panel includes a first attachment structure. The first attachment structure is sized and shaped to complementarily engage a second attachment structure on one or more end-pieces. Those one or more end-pieces would have a second attachment structure sized and shaped for releasable attachment to the first attachment structure and an accessory device mounting structure sized and shaped to releasably secure an accessory device. 
     In another embodiment, the clip body with communication system can be incorporated in the system for interchangeable mounting of accessory devices on a hat brim. In this respect, the system includes the clip body immediately described in which the proximal end of the first panel includes a first attachment structure. The clip body can be part of a system utilizing one or more interchangeable end pieces that attach to the proximal end of the first panel. Those one or more end-pieces would have a second attachment structure sized and shaped for releasable attachment to the first attachment structure and an accessory device mounting structure sized and shaped to releasably secure an accessory device.

     DETAILED DESCRIPTION 
     A preferred embodiment of the present invention accessory mounting clip  1  and its preferred constituent features are shown in  FIGS. 1-10 ,  FIGS. 13A-13D  and  FIGS. 14-17 . For reference purposes the term “distal end” is used to refer to that portion of the clip or its components that are furthest away from a user&#39;s head when the clip is deployed on the brim of a hat. The term “proximal end” is used to refer to that portion of the clip or its components that are nearest the user&#39;s head when the clip is deployed on the brim of a hat. The preferred embodiment clip works particularly well when used to mount accessories on the brim (a/k/a bill)  71  of a baseball cap  70  such as is shown in  FIGS. 12A and 12B . As shown in  FIGS. 12A and 12B , brim  71  typically has a front edge  72  that has a front to back curvature of certain radius. Brim  71  also has a thickness  74 . Brim  71  also has a transverse curvature or bend of a certain radius that is best discerned when looking at the cap head on. 
     As shown by the figures, clip  1  is springless, which distinguishes the clip from the alligator clip style mounting clips. Preferred embodiment clip  1  is sized and shaped to attach to brim  71  by way of a pair of pinching panels  2 ,  3  between which brim  71  is inserted. Accordingly, clip  1  comprises a first panel  2  and a second panel  3 . In common usage, first panel  2  is an upper (top) panel and second panel  3  is a lower (bottom) panel. First panel  2  and second panel  3  define space  80  into which a brim is inserted. First panel  2  and second panel  3  respectively have a length  7 ,  14 , a width  8 ,  15 , thickness  9 ,  16 , a top surface  10 ,  18 , a bottom surface  11 ,  17 , a proximal end  6 ,  13  and a distal end  5 ,  12 . 
     First panel  2  and second panel  3  each resiliently connect at heir distal ends  5 ,  12  to nose segment  4 . Nose segment  4  comprises a front facing (outer) surface  26  and a brim facing (inner) surface  27 . Top  19  of nose segment  4  connects to distal end  5  of first panel  2 . Bottom  20  of nose segment  4  connects to distal end  12  of second panel  3 . Proximal end  13  of second panel  3  may be chamfered to better guide brim  71  into space  80  between panels  2 ,  3 . Front facing surface  26  may include a logo or brand name  41  printed or embossed thereon Likewise, distal end  3  of panel  2  may also include a logo or brand name  41  printed or embossed thereon. 
     Importantly and in contra-distinction to the prior art, second panel  3  has a wedge-shaped (a/k/a “delta-shaped”) portion  52  in which the width  15  of panel  3  increases from its distal end  12  to its proximal end  13 . In the preferred embodiment, wedged-shaped portion  52  is formed by a pair of flaring side segments  21 , each of which leads into a distal segment  22 . In the preferred embodiment distal segments  22  are parallel to each other. 
     The angular arrangement of side segments  21  with distal segments  22  of wedge-shaped portion  52  of lower panel  3  create fabric-catching edges  64  that are forced into the relatively softer cloth surface of brim bottom surface  76  when clip  1  is deployed on a brim  71 . In the preferred embodiment, distal segments  22  meet flaring side segments  21  at an obtuse angle. Edges  64  allow second panel  3  of clip  1  to cut into and frictionally engage the bottom  76  of hat brim  71  due to the transverse curvature of brim  71 . This frictional engagement increases the purchase of clip  1  against hat brim  71 . 
     As seen in the figures, first panel  2  and second panel  3  adjoin nose segment  4 . First panel  2  and second panel  3  are separated along almost their entire lengths by vertical space  80 . At the distal end of clip  1 , the height of vertical spacing  80  between first panel  2  and second panel  3  is roughly equal to thickness  74  of hat brim  71 . As one moves from the distal end of clip  1  to its proximal end, spacing  80  decreases until panels  2 ,  3  make contact. Preferably, proximal end  13  of second panel  3  will touch panel  2  at a point about 75% of its length as measured from distal end  5 . This decrease in spacing between panels  2 ,  3  increases frictional purchase of clip  1  against brim  71 . The resilient connection of panels  2 ,  3  to nose segment  4  allows spacing  80  at the proximal end of clip  1  to increase via resilient deflection so as to receive a hat brim  71 . 
     Also adding to the friction-creating contact between clip  1  and hat brim  71  is the fact that the clip can have one or more concave and convex surfaces that increase surface contact between the clip and hat brim. For example, as shown in the figures, bottom surface  11  of first panel  2  is concave. In the preferred embodiment, this concavity has a radius closely equal to that of transverse curvature of brim  71 . This allows for increased surface contact between the top surface  77  of hat brim  71  and bottom surface  11  of panel  2  and hence an increased frictional hold. This increased frictional hold is augmented by the shape of second panel  3 . In this respect, as shown in the embodiment shown in the figures, top surface  18  of second panel  3  is convex. The convexity preferably has a radius closely equal to that of transverse curvature of brim  71 . This convexity may also be found in floor  31  of channel  30 . Additionally, as best shown in  FIG. 17 , brim-facing, inner surface  27  of nose segment  4  may be concave in one or more dimensions. For example, constituent portions  27   a,    27   b  and  27   c  may have a front-to-back concavity that more preferably mirrors that of the edge curvature of edge  72 . Constituent portions  27   a,    27   b  and  27   c  may also have a vertically oriented curvature to better receive the vertical curvature of brim edge  72 . It is intended that these concave portions of nose  27  increase purchase against brim edge  72 . Also, channel sidewall  32  is preferably formed in convex fashion to increase the hold of fabric border  79 . 
     Preferred embodiment clip  1  includes cutouts  42  formed in proximal end  13  of second panel  3 . Cutouts  42  reduce weight and allow proximal end  13  of panel  3  to flex more in relation to its distal end  12 . This increased flexibility allows panel  3  to conform to the curvature of under surface  76  of brim  71  thereby increasing surface to surface contact between the clip and the hat brim. 
     As seen in the figures, top surface  10  of first panel  2  includes mounting structure  38  adapted (sized and shaped) to receive an accessory device such as a light or POV camera. Mounting structure  38  may be integrally formed in first panel  2  as shown in the figures or may be mechanically attached. Mounting structure  38  of preferred embodiment clip  1  shown in the figures is particularly adapted to receive the mounting structure of a GoPro brand POV camera. Other mounting structures may be used. Unlike some prior art accessory mounting devices that place the mounting structure at the distal end of the device, mounting structure  38  of the present invention clip is positioned at the proximal end  6  of first panel  2 . 
     Preferred embodiment clip  1  can include one or more enhancements to increase its brim-holding power. For example, all or part of top (inner) surface  18  of second, bottom panel  3  may be texturized to increase friction with bottom surface  76  of brim  71 . Such texturizing can involve application of a rubberized surface to top surface  18 . Alternatively or additively, top surface  18  may include a knurled surface, a roughened surface, a surface with upward facing micro-points or a surface with rough fibrous surface texture. By texturizing all or part of top surface  18  the coefficient of friction between clip top surface  18  and brim bottom surface  76  is increased. In addition, second panel  3  preferably becomes more flexible (compared to the distal portion) near the widest portions, which allows second panel  3  to better form to the curvature of brim  71 . 
     In a preferred embodiment, the width of second panel  3  at its proximal end is 1.5 to 2.5 times the width of the first panel at its proximal end. Tests of various iterations of the inventive clip  1  have shown that clip  1  offers optimal frictional purchase against brim  71  when the width  15  of second panel  3  at its proximal end  13  is approximately 2 times the width  8  of the first panel  2  at its proximal end  6 . 
     The shape and structure of nose segment  4  have been shown to also significantly increase the ability of clip  1  to resist movement on the bill of a conventional baseball cap. For example, nose segment  4  connects in general perpendicular relation to each of the first and second panels  2 ,  3 . This allows front edge  72  of brim  71  to be pushed flush up against brim-facing surface  27  of nose segment  4 . To further increase the frictional purchase of clip  1  on brim  71 , distal end  12  of panel  3  includes a channel  30 . Channel  30  has a floor  31  and a sidewall  32 . Sidewall  32  rises to top surface  18  of second panel  3  at its distal end  12 . The positioning of channel  30  relative to inner (brim-facing) surface  27  of nose portion  4  and the decreasing vertical space  80  between panels  2 ,  3  operate to force the proximal edge of fabric border  78  into sidewall  32 , augmenting the frictional hold of the clip on brim  71 . At the same time and also augmenting the frictional hold, brim edge  72  is forced into brim-facing surface  27 . 
     The purpose of channel  30  will now be further explained. As seen in  FIG. 12B , a typical brim of a baseball cap includes stitching  79  on the bottom surface  76  of brim  71 . Stitching  79  defines a border  78  of cloth material between stitching  79  and brim front edge  72 . This border  78  of cloth material (indicated by the cross-hatched area in  FIG. 13D ) typically has a width and an additional thickness. For a large amount of readily purchasable baseball caps, the width of cloth material border  78  falls within a range of 0.584 to 0.686 centimeters. Channel  30  is preferably sized to fall within that range. When clip  1  is fully seated on brim  71  such that brim edge  72  is in contact with brim-facing surface  27  of nose portion  4 , border  78  of cloth material tends to drop in and be retained by sidewall  32  of channel  30 . This retention of border material  78  by channel  30  increases the frictional hold clip  1  has on brim  70  particularly when channel  30  is constructed in the preferred embodiment as is immediately described. In this respect floor  31  of channel  30  connects to sidewall  32  in general perpendicular relation. Similarly, in the preferred embodiment sidewall  32  of channel  30  connects to panel  3  in general perpendicular relation at a corner  54 . Corner  54  may include a bevel  55  to aid in insertion and removal of brim  71  from clip  1 . Corner  54  digs into bunched fabric of border material  78  and assists in retaining clip  1  in a fixed position on brim  71 . 
     As noted, channel  30  may be further enhanced such that floor  31  of channel  30  follows the convex contour (best seen in  FIG. 4 ) of top surface  18  of panel  3  and is thus itself upwardly convex. The convexity of floor  31  has a preferred radius closely equal to that of transverse curvature of brim  71 . Also, as can be best seen in  FIGS. 7, 10 and 14  brim-facing surface  27  of nose segment  4  is preferably concave in the front-to-back direction and that concavity can have an optimal radius closely equal to that of the radius of the edge curvature of brim edge  72 . This concavity in inner, brim-facing surface  27  increases the surface area contact of clip  1  with brim edge  72 . As with top surface  18  of panel  3 , brim facing surface  27  may be texturized to increase its purchase on brim edge  72 . Additionally, as is shown in  FIG. 10 , sidewall  32  is convex and the radius of the convexity is preferably closely equal to the radius of curvature of brim front edge  72 . This convexity allows sidewall  32  to have a larger contact surface with bunched fabric border material  79 . 
     Preferred embodiment clip  1  may include elongate ribs  46  on top surface  10  of panel  2 . Ribs  46  add structural rigidity to first panel  2 , which prevents it from twisting and flexing When the weight of an accessory item is applied to clip  1 . In the depicted embodiment ribs  46  are longitudinally oriented on panel  2 , but can be also be oriented transversely or diagonally on panel  2  to achieve a desired directional rigidity. Ribs  46  also serve as a rest stop or support for a camera or other device that can flip downward from mounting structure  38 . Ribs  46  thereby protect the sensitive surfaces such as the lens surfaces of such cameras. 
     Users deploying POV cameras on their hats often find it difficult to know if their camera is properly positioned or angled to record the best scene. To remedy this problem clip  1  may include a position stop  57  on or operable with accessory mounting structure  38 . Such an alternate embodiment clip is shown in  FIGS. 15A and 15B , which show a stop  57  as part of a mounting structure  38  sized and shaped to secure a GoPro brand camera. In operation a user will position stop  57  on mounting structure  38  through trial and error to find the best positioning angle of whatever device (e.g., light or POV camera)  39  he or she is using. Once that optimum positioning angle is determined, the user can then set and fix (preset) stop  57  to the correct location on mounting structure  38 . Afterwards, a user can simply mount the selected device  39  to clip  1  and angle the device against stop  57  and be assured that the device in properly angled (according to the usual and customary way the user wears his or her hat) to best capture or illuminate the area in front of the user. Hence, deploying the accessory device on the clip can be performed repeatedly quick and easily. 
     As shown in the figures, clip  1  may also include a thin (non-obscuring) tab  65 . Tab  65  depends from second panel  3  and provides a vertical surface  67  (which may be angled as shown in the figures) upon which a user&#39;s thumb or finger can push against to remove clip  1  from brim  70 . In a more preferred embodiment, clip  1  may include display tab  66  depending from panel  3 . The embodiment clip shown in the figures includes both types of tabs  65  and  66 , but the clip could include either tab individually. Tab  66  is designed not limitedly for removal of the clip, but to provide a mechanism by which the user can be alerted to one or more operational statuses of a mounted device. In this embodiment, vertical surface  67  of tab  66  may include one or more indicators (shown by way of example in the embodiment as lights)  68 . One or more indicators  68  are part of an electronic receiving circuit (not shown) that is in wireless communication with device  39  (such as via will or Bluetooth signaling). The communication between the device and the receiving circuit of display tab  66  allows the one or more indicators to indicate to the user various statuses of the device. Such statuses could include the situation where the device: is recording, not recording or is running low on charge or battery power. 
     A clip constructed in accordance with the present invention is able to securely retain and position common accessory devices, including the heavier camera and light devices, The clip can be manufactured in a variety of sizes to accommodate different size hat brims. The clip may be made of a plastic, carbon fiber or metal base material. If plastic, the clip is preferably injection molded or 3D-printed from plastic. 
     The design of the inventive clip described above also has beneficial application as the foundation for a two-piece clip or a clip system that allows for interchangeable attachment of a variety of device mounting structures. In this respect, many accessory device manufacturers utilize distinct mounting supports for their devices. In many cases, these mounting supports are not compatible with other devices. Thus, it would be beneficial to have a clip device that allows for interchanging of mounting supports to allow mounting of these devices from different manufacturers. This can be done via an inventive system in which a clip body includes at its proximal end structure to releasably engage end-pieces allowing for a variety of mounting supports. In the preferred embodiment the clip body substantially meets the design of the above described clip. The components of such an embodiment system are shown in  FIGS. 18-26C . 
     In one embodiment, a system for interchangeable mounting of accessory devices on a hat brim comprises a clip body  401  and one or more end-pieces  490 . Clip body  401  comprises a top (first) panel  402  and a bottom (second) panel  403 . Top and bottom panels  402 ,  403  respectively have a length  407 ,  414 , width  408 ,  415 , inner surface  411 ,  417 , outer surface  410 ,  418  proximal end  406 ,  413  and distal end  405 ,  412 . Top panel and bottom panel  402 ,  403  are each resiliently connected at their distal ends to nose segment  404 . Nose segment  404  has an outer (front-facing) surface  426  and an inner (brim-facing) surface  427 . Bottom panel  403  has a wedge shaped portion  452  in which the width  408  of the panel  403  increases from distal end  412  of panel  403  to proximal end  413  of the panel  403 . Clip body  401  may have all of the features described above for clip  1  sans the integral mounting structure  38 , which is instead replaced by an attachment mechanism  491  sized and shaped for complementary attachment to an end-piece  490 . By having a system including multiple end-pieces  490 , each with a mounting post  438  for a different accessory mounting mechanism, the interchangeability of end-pieces  490  allows the clip system to be used for a multitude of accessory devices. 
     In the preferred embodiment system, clip body  401  will share many of the structural features as are or may be included on clip  1 . In this respect, on clip body  401  the inner (bottom) surface of first panel  402  is concave and the inner (top) surface  418  of second panel  403  is convex. Proximal end  406  of first panel  402  includes a first attachment structure  491 . The one or more end-pieces  490  include device mounting structure  438  and a second attachment structure  492  sized and shaped for releasable complementary attachment to first attachment structure  491 . Preferable structure for complementary attachment structures  491 ,  492  include a tongue and slot arrangement, whereby a tongue  493  on clip body  401  frictionally inserts and is engaged by slot  494  on end-piece  490 . Such exemplary complementary structure is shown in  FIGS. 18-26C . Other types of mechanical engagement methods may be used such as a side release buckle or a slide entry flared bead/undercut track structural arrangement. Mounting structure  438  on end-piece  490  can include a positioning stop allowing a user to preset a position of the accessory device on the clip. By utilizing a system comprising a clip body with interchangeable end pieces, a wider variety of end pieces and mounting structures can be utilized with the system. For example,  FIG. 36  shows an embodiment system showing end-piece  490  attached to clip body  401 . As seen in this figure, end piece  490  has dual mounting structures  438   a  and  438   b  that allow the clip system to receive multiple lights, multiple cameras or a camera and a light. 
     Note that the invention is also drawn to the clip body of the immediately described system that allows for interchangeable mounting of accessory devices on a hat brim. The clip body has the physical structures described above, particularly proximal end  406  of top panel  402  including a first attachment structure  491  sized and shaped to releasably attach to a complementary second attachment structure  492  connected to an end-piece  490 . 
     In another embodiment, the design of the present invention clip and also the systems using a similarly structured clip body of  FIGS. 18-26C  can be adapted to include a mount for holding a microphone/jack. Such an enhanced clip is shown in  FIGS. 27-32 . As shown in those figures, a clip  501  (or the clip body  401 ) for mounting accessory devices on a hat brim comprises the same structural elements as the inventive clip  1  described above. Clip  501  thus comprises two panels  502 ,  503  and can also have one or more of the additive features described above for clip  1 . Clip  501  further includes mount  595 . Mount  595  is sized and shaped to releasably hold a readily purchasable microphone/jack  596  in wired or wireless electrical communication with an accessory device  539  mounted on the clip. 
     Microphone/jack mount  595  preferably descends from outer surface  517  of lower (second) panel  503 . Mount  595  may be integrally formed in lower panel  503  or panel  503  may be formed to mechanically receive microphone/jack mount  595  such as by providing outer surface  517  with a friction fit receiving hole to receive a post formed in mount  595 . Mount  595  could also be attached to lower panel  503  via an adhesive. The wedge-shaped portion  552  of panel  503  (particularly cutout  542 ) provides an ideal location at which to provide receiving means by which to frictionally engage a microphone/jack mount  595 . For example, cutout  542  could itself be the receiving means in which to insert a press-fit, silicone projection attached to microphone/jack  596 . Additionally, in some recording situations it is preferable that the microphone/jack  596  point towards the user&#39;s face so that the microphone fully captures the user&#39;s narration. As shown in the figures, in the depicted embodiment, microphone/jack mount  595  is preferably sized and shaped so as to releasably hold the microphone/jack  596  in a position whereby the microphone/jack  596  points in a direction down and away from the nose segment  504  of the clip  501  (i.e., towards the face of a user wearing the hat on which clip  501  is mounted). 
     In a more preferred embodiment, clip  501  includes wire-holding means  598  to releasably engage a wire  599  leading from an accessory device  539  mounted on clip  501  to a microphone/jack  596  held by the mount. A preferred wire-holding means  598  is a channel  598   a  integrally formed in the clip. Alternative wire-holding means  598  includes one or more spring clips integrally formed in clip  501 . 
     The microphone/jack mount design works particularly well with arrangements that include a microphone cable  599  that can interface with the mini USB connection on a camera. An appropriate length cable  599  is one that extends from a device  539  mounted at the proximal end of clip  501 , along the length of clip  501  and on to the lower surface  517  of bottom panel  503 . Cable  503  may be directly connected to a microphone/jack  596 . As seen in the figures, after cable  599  descends from the accessory device (camera)  539 , cable  599  threads through clip  501  through integrated wire holding mechanism  598 . This is best seen in  FIG. 30  in which integrated wire holding mechanism  598  is embodied as channel  598   a.  This design leads to a fully and direct integration of a microphone with the hat clip for a lower profile and weight reducing option. The integrated wire holding means  598  means that any wire between device  539  and microphone/jack  596  follows the contour of clip  501  in close proximity to clip  501  and thus is particularly beneficial in reducing dangling cable or cable slack that can be snagged by external structure such as leaves, branches or other projecting elements. 
     As shown in the figures, microphone/jack mount  595  is preferably in the form of a two-prong spring clip allowing the microphone/jack  596  to be press fit into the clip and retained.  FIG. 29  is a front elevation view of an alternative embodiment clip  501  including a mount  595  adapted to releasably hold a microphone/jack in electrical communication with an accessory device mounted to the clip. Clip  501  of  FIG. 29  has an offset device mounting structure  538 . 
     The design of the inventive clip  1  described above also has beneficial application as part of a clip system that allows for attachment of accessory devices to brims of varying thicknesses. An embodiment of such a system is shown in  FIGS. 33, 34A and 34B . In this respect, though the clip described above has shown to have good application on the common brim thicknesses found on commercially available baseball caps, the variance in brim thicknesses can affect the purchase of clip  1  on the brim. Thus, it would be beneficial to have a way to adjust the height of the spacing  80  defined by the top and bottom panels of the clip. This can be done via an inventive system in which a clip body  601  meeting the design of the above described clip  1  releasably engages an insert  701  that can be used to vary the vertical spacing  680  between top and bottom panels  602 ,  603  of clip body  601 . Insert  701  can be sized and shaped so as to engage and cover either or both of panels  602 ,  603 . The system can include one or more interchangeable inserts  701  of varying thicknesses, textures and size. 
     An embodiment system for mounting accessory devices on a hat brim is depicted in  FIGS. 33-34B . Such an embodiment system comprises clip body  601  and one or more inserts  701 . Clip body  601  comprises a top body panel  602  and a bottom body panel  603 . Top body panel  602  and bottom body panel  603  respectively have a length and a width akin to that of clip  1 . As shown in  FIGS. 33 and 34A , top body panel  602  and bottom body panel  603  respectively have an inner surface  611 ,  618 , an outer surface,  610 ,  617 , a proximal end  606 ,  613  and a distal end  605 ,  612 . Top body panel  602  and bottom body panel  603  are each connected at their distal ends  605 ,  612  to a body nose segment  604 . 
     Body nose segment  604  has an inner surface  627  and an outer surface  626 . Bottom body panel  603  has a wedge shaped portion  652  in which the width of bottom body panel  603  increases from distal end  612  of panel  603  to proximal end  613  of the panel. As with clip  1 , the width of body bottom panel  603  at its proximal end  613  is preferably 1.5 to 2.5 times the width of top body panel  602  at its proximal end  606 . Inner surface  611  of top body panel  602  is preferably concave. Inner surface  618  of bottom body panel  603  is convex. Outer surface  610  of top body panel  602  at proximal end  606  of top body panel  602  includes mounting structure  638  sized and shaped for receiving an accessory device such as a camera or light. 
     As best seen in  FIG. 34B  insert  701  includes an insert first panel  702 . Insert  701  is sized and shaped so as to be received by clip body  601  whereby insert  701  is engaged by and contacts one of the panels of clip body  601  to reduce the intra-panel spacing  680  of clip body  601 . In the depicted embodiment, insert first panel  702  of insert  701  is releasably engaged by clip body  601  and insert first panel  702  contacts inner surface  611  of top body panel  602 . Preferably, insert  701  will contact all or a majority of an inner surface of clip body  601  (inner surface  611  of top body panel  602  in the depicted embodiment). Generally, the more surface of clip body  601  that insert  701  covers, the better the fabric gripping ability. In one embodiment, insert  701  is made from the same material as clip body  601 . In another embodiment, insert  701  is made from a softer more resilient plastic or rubber material than is clip body  601 . Inner surface  711  of insert  701  may be texturized to improve brim-gripping ability. 
     As noted above, insert  701  can be sized and shaped so as to engage and cover either or both of panels  602 ,  603 . In an enhanced system embodiment shown in the figures, insert  701  further includes insert nose segment  704  connected to insert first panel  702 . Nose segment  704  is sized and shaped such that when insert  701  is received by clip body  601 , insert nose segment  704  contacts inner surface  627  of nose segment  604  of clip body  601 . Bottom body panel  603  may include a channel  630  proximate to the connection point between the body nose segment  604  and the bottom body panel  603 . In the embodiment depicted in  FIGS. 33-34B , insert  701  is sized and shaped to cover and engage top panel  602  and contact inner surface  627  of nose segment  604 , while having a short segment  703  that is received by channel  630  on lower panel  603 . This is not meant to be limiting as the invention is broadly directed to a system comprising a clip and insert that reduces the spacing between the two panels of the clip. As in the case of clip  1 , channel  630  of clip body  601  can include a floor  631 . The floor of channel  630  is preferably convex. Channel  630  also preferably includes a sidewall  632  which is convex. 
     In an alternative embodiment, insert  701  could comprise a top insert panel and bottom insert panel. The two panels could be integrally connected through a nose section or could be separate pieces, in such an arrangement, the system would comprise a clip body as described above and a top insert panel (which would look like panel  702 ) and a bottom insert panel sized and shaped so as to be releasably engaged by lower panel  603  of clip body  601 . The bottom insert panel contacts inner surface  618  of bottom body panel  603 . Preferably, insert  701  will contact all or a majority of inner surface  611  of top body panel  602 . This system may include an insert nose segment (such as nose segment  704 ) connecting top insert panel  702  to the bottom insert panel. Insert nose segment  704  is sized and shaped such that when top insert panel  702  and the bottom insert panel are releasably engaged by clip body  601 , insert nose segment  704  contacts inner surface  627  of body nose segment  604 . Top insert panel  702  and the bottom insert panel have respective inner surfaces, which may be texturized. The distal end of the bottom insert panel can include a channel as described above for clip  1 . 
     The systems described above may include the above-described positioning stop (not shown in  FIGS. 33-34B ) that allows a user to preset a position of the accessory device on the clip. The systems may also include a tab  665 , microphone/jack mount  595  or both depending from bottom body panel  603 . Tab  665  may be structured as described above for clip  1 . 
     In an alternative embodiment, any of the clip or clip bodies described herein can include a battery compartment to hold a battery that can power either or both of the indicators mentioned herein or the accessory mounted on the clip. In this respect,  FIG. 35  is a top plan view of an embodiment of a clip system including a body  801  with adjoined end piece  890 . The clip body includes battery compartment  896 , which is sized and shaped to hold a battery. In the case where the battery powers the indicators on the clip or clip body, compartment  896  would include electric wires or conduit to achieve electrical communication between batteries held in compartment  896  and the indicators. In the case where the battery powers the accessory on the clip or clip system, compartment  896  would include electric wires or conduit leading to a plug-in point that would allow the accessory to plug into and be supplied by the battery source held in compartment  896 . 
     The design of the inventive clip, clip system and clip body described above also has beneficial application as the foundation for a wearable personal communication device that effects communication with a user&#39;s mobile device such as a mobile phone, iPad or notebook computer. In general, the communication system  900  is housed on second panel  3 ,  403  of the clip  1  or clip body  401 . The clip body  401  or clip  1  when so enabled provides for a wearable personal assistant in the form of a hands-free communication device that includes a processor (controller), one or more a built-in speakers, a built-in microphone  901  and a control interface  902  receiving actions from a user. The communication system pairs with a user&#39;s mobile device  950  so that the user can engage in a variety of functions handled by the mobile device such as: a) using the brim clip&#39;s communication system to engage in phone calls received and made by the mobile device  950 ; b) operating applications and features of the mobile  950  device through tactile inputs or voice commands made to the communication system on the brim clip  1  or clip body  401 ; or c) sending texts via voice commands made into the microphone  901  of the brim clip communication system  900  that the system relays to the mobile device  950  for delivery. In its most basic usage the brim clip  1  or clip body  401  with communication system  900  will process signals received from the mobile  950  device to produce audio outputs by the built-in one or more speakers  903  and will correspondingly process audio sounds from the user and transmit signals to the mobile device  950 , allowing the user to engage in a cellular phone conversation enabled by the mobile device  950  without using his or her hands. Additionally, the processor  904  will receive the signals corresponding to the user action imparted to the control interface  903  and is configured to automatically pair through Bluetooth to the mobile device  950  video and audio signals captured by the KW camera (represented schematically as  39  in  FIG. 46 ), allowing others looking at the mobile device to see and hear what has been captured. 
     In more detail, one embodiment of the invention is directed to a clip  1  for mounting on a hat brim. This embodiment is shown in  FIGS. 37-40 . Clip  1  has a first panel  2  and a second panel  3  with the features shown in  FIGS. 1-10 and 13A-17 .

Control interface  902  should be located on bottom surface of the second panel for ease of accessibility. As shown in  FIG. 43 , the proximate end of panel  3 ,  403  also offers an area at which interface buttons can be placed. Though the primary purpose of the second panel communication system  900  is to control and communicate with a mobile device  950  such as mobile phone, tablet computer, netbook or other portable computer, the communication system can additionally communicate with an accessory device  39  carried by the clip  1 , system or clip body  401 . Accessory device  39  can be controlled through control interface  902  of the communication system  900 . In one embodiment, the first panel of the end piece insertable into the clip body of the inventive clip, system or clip body can include a strobe light. The strobe would preferably be located at the proximal end of the first panel or end piece and can be placed in operative communication with the communication system  900   
     In preferred embodiments of the communication system  900  of the inventive clip  1 , system or clip body  401 , control interface  902  includes a switch button  913 , a first volume button  914 , a second volume button  915  and a mode button  916 .

The battery compartment could be on the top (first) panel as described previously above. The wireless communication module  906  is preferably an RF transceiver  912  within housing  908  of the second panel and is configured to perform wireless communication with mobile device  950 . RF transceiver  912  may be Bluetooth chip that establishes two-way communication between the communication system  900  on the second panel and the mobile device  950 . 
     Control interface  902  preferably includes one or more buttons  913 - 916  provided on housing  908  on the bottom surface of the second panel. Buttons  913 - 916  preferably allow for push operations for controlling operation of the system  900  and one or more of microphone  901 , the one or more speakers  903  and mobile device  950 . Processor  905  is contained within housing  908  and is in electrical communication, preferably through circuitry, with one or more batteries  904 , microphone  901 , control interface  902 , one or more speakers  903  and communication module  906 . Communication system  900  may optionally have memory/file storage  919 . Processor  905  is configured to: (a) process a signal input from microphone  902  and output the processed signal to the RF transceiver  912 ; (b) process a signal received from the RF transceiver  912  and output the processed signal to the one or more speakers  903 ; and (c) process a signal input according to the push operations of the one or more buttons  913 - 916 . Communication system  900  preferably has a memory  919  within housing  908  of the second panel in electronic communication with processor  905 . Memory  919  stores program instructions for executing a plurality of functions triggered by user input to processor  905  via control interface  902  on the second panel, microphone  901  or from on mobile device  950 . Buttons  913 - 916  on control interface  902  can be configured to perform certain functions via the graphic interface on mobile device  950 . 
     As is common, microprocessor  905  can be programmed such that when communication is established with mobile device  950 , mobile device  950  displays a graphical user interface  917  allowing operative control of communication system  900  on the second panel. Exemplary mobile devices include an Android smartphone, an iPhone smartphone, a tablet computer, a netbook computer. Similar to current Bluetooth devices that attach to a user&#39;s ear, a user wearing the inventive brim clip with communication system could engage in hands free phone calls via the communication system&#39;s linking with the user&#39;s nearby mobile device. Included among the plurality of functions offered by the communication systems is a mute function operable to cause the processor to toggle the microphone between a muted and an unmuted state responsive to the button on the control interface being pressed. The communication system can include a speed dial function operable to cause the processor to send a command to the mobile device to place an outgoing call to a pre-selected telephone number. By way of example the pre-selected telephone number is selected from the group consisting of a telephone number designated as the user&#39;s home number, a designated entry in a speed dial list or favorites list on the mobile device, or a last telephone number dialed by the mobile device. 
     Via processor  905 , communication system  900  of the clip/system/clip body can be wirelessly electronically paired with a mobile device  950 . Through buttons  913 - 916  on interface  902  or through oral command received via the microphone, the processor is configured, to communicate with the mobile device  950  to launch a pre-selected application on the mobile device. Exemplary functionality can include processor  905  being configured, in response to the configurable function button being pushed or voice command, to launch a voice recognition function on the mobile device. Similarly, the communication control interface can be configured such that when a button is pushed a microphone channel is opened between the microphone and the processor and, in response to a function button being released or pressed again, to close a microphone channel between the microphone and the processor. The communication system  900  may also provide for a voice recording function upon the pressing of an interface control button. In such exemplary functionality, the processor is configured to receive an audio signal from the microphone, convert the audio signal into a digital audio file, and store the digital audio file in the memory. The processor may be configured to provide a battery charge indication in response to a control interface or voice input. Alternatively or additively, housing  908  may include a battery charge indicator  920  advantageously located on the proximal end of panel  3 ,  403  to inform the user of a battery level state. 
     In more specific detail the communication system  900  is carried on, but more preferably integrated into, a brim clip  1  or the clip body  401  of the described systems to provide wearable audio and communication functionality for the user. In other embodiments, the communication system  900  of the second panel of the brim clip  1 , system or clip body  401  can include an imbedded file storage module  919  in communication with the processor. The file storage module  919  will allow the storage of files such as music, pod casts or similar types of audio files which the processor can access and play through the one or more speakers. Memory  919  can also store video files. 
     Preferably, control interface  902  is configured to enable the user to perform a control operation on the audio source (whether the origin of the audio is the mobile device  250  or a music playing function within the processor), wherein the user interface  902  is configured to enable user to input at least one of the following commands: on, off, play, pause, stop, forward, rewind, skip, answer a call, end a call, volume up, volume down, mute, redial, text or call. Similarly, microphone  901  allows the user to communicate with processor  905  on the second panel to effect control functions such as on, off, play, pause, stop, forward, rewind, skip, answer a call, end a call, volume up, volume down, and mute. In one exemplary functionality, the user can communicate via the microphone with the communication system on the second panel Which in turn communicates with the mobile device, which has a second communication interface. Thus, the user can utilize the interface of the mobile device to program or control operation of communication system  900 . Bluetooth signals are preferable short range radio signals to use to effect communications between a wearable device and a mobile device. 
     In another embodiment, the communication system can include a communication module  906 , such as a Wi-Fi, that permits the user to communicate with electronic devices, such as desk-top computers or mobile devices at a distance, or with networks. Further the communication system can communicate with and store information from wireless communication-enabled devices often worn by users such as, accelerometers, gyroscopes, inertial measurement units, global positioning systems, heart rate sensors, blood pressure sensors and temperature sensors through communication protocols such as ANT+. In addition, the communication device can communicate with an accessory device held by the clip such as a POV camera or a light. This would make the accessory device controllable via the communication device&#39;s control interface or through voice commands and not require direct manipulation of the accessory device. In further detail in this respect, the communication device on the second panel can establish communication between a camera carried by the clip and the user&#39;s mobile device (and control the communication) so that others can share the scene being recorded from the user&#39;s point of view (akin to Apple&#39;s FaceTime feature). Through its connection with the mobile device, the communication device could link the mobile device and the accessory device to allow hands-free streaming of POV video to others in communication with the user&#39;s mobile device. The communication device on the second panel can also be used through voice or button to control an accessory device carried by the clip. 
     As shown in  FIG. 47 , through the inventive clip and clip body, a communication device can be positioned directly under the hat brim  71  in an optimum location for the user. This is stark contrast to other available prior art systems. The secure positioning of the communication system assures easy and efficient use because both speaker(s)  903  and microphone  901  are in ideal positions for use when speaking and listening. In this respect, the preferred embodiment, speakers  903  point toward and project sound to the ears of the wearer. Similarly, microphone  901  is directly in place for conversation. No electronic devices directly touch the skin and no earpieces occlude environmental noise from being received by the user&#39;s ear. A user&#39;s awareness around him is not diminished by reducing peripheral environmental noise by having the ears covered or earbuds inserted. Thus, when a user is in motion, such as when running or walking, the user can make voice commands, talk on the phone, text or listen to music hands free without devices impeding the ear. Additionally, the brim clip (or clip body) with incorporated communication system has great application for drivers, particularly those that do not have or cannot afford an in-vehicle Bluetooth system. Those drivers without in-vehicle Bluetooth systems either use their mobile phone near their face while driving or opt for after-market options. Currently, available after-market options for in-vehicle Bluetooth connectivity offer dashboard or visor mounted devices. These tend to not work well because of background noise and poor positioning of the devices relative to the users mouth and ears. The inventive brim clip with incorporated communication system eliminates these problems by placing the speakers and the microphone in the right place, near the mouth and ears. Additionally, a user could employ the brim clip when working around the house or yard without having to keep his or her hands on a phone. For those instances in which a user wanted to use ear buds, the housing of the communication system could include an interface (jack) for ear phones or ear pieces. The interface would communicate electrically with the processor. Additionally, the proximal end of the communication system could include a display to visually indicate to the user a message such as the receipt of a text message, the content of a text message or the receipt of a phone call by the user&#39;s mobile device. 
     While the embodiments of the method and system of the present invention have been described herein, numerous modifications, alterations and changes to the described embodiments are possible without departing from the scope of the invention. The embodiments described herein are not ended to be limiting. In particular the various enhancements such as the microphone mounting feature, the interchangeable device mounting structure and the interchangeable sizing insert can be incorporated separately or additively with the various described embodiments.
