BACKGROUND OF THE INVENTION FIELD OF THE INVENTION

[001] One or more embodiments setting forth the ideas described throughout this disclosure pertain to the field of mounts as utilized in sporting equipment for electronics and visual markers. More particularly, but not by way of limitation, one or more aspects of the disclosure enable a motion capture element mount.

DESCRIPTION OF THE RELATED ART

[002] Known systems for mounting electronics on sporting equipment include mounts in the shafts of fishing poles, and golf clubs for example. Existing mounts have the following limitations:

• Existing mounts for sporting equipment electronics require alteration of an existing piece of sporting equipment before attaching the mount and hence electronics. For example, known mounts require modification of the shaft of the piece of equipment to include threads. • Some mounts extend longitudinally away from the normal ending point of the shaft for a distance that is far enough to interfere with or provide a confusing point at which to grasp the club.

• Other mounts combine the electronics on the mount itself in a monolithic package that does not allow for the weight of the club to remain constant with or without electronics installed. For example, in sports with rules against instrumented sporting equipment, the weight of an instrumented piece of sporting equipment differs from the weight of the same non-instrumented piece of sporting equipment that complies with competition rules.

• There are no known systems that include electronics within the shaft of a piece of sporting equipment that are also utilized to provide a visual marker for motion capture. Traditionally, mounts have been used for electronics or visual markers, but not both.

[003] For at least the limitations described above there is a need for a motion capture element mount.

BRIEF SUMMARY OF THE INVENTION

[004] Embodiments of the invention enable an enclosure and mount for motion capture element that enables a durable and secure coupling of the motion capture element to a piece of sporting, exercise or medical rehabilitation equipment, for example a baseball bat, hockey stick, lacrosse stick, helmet, skateboard, ski, snowboard, surfboard, golf club, tennis racquet, weight training bar, or any other equipment capable of movement. In addition, embodiments enable existing equipment that was not manufactured originally with a mount for electronics to be retrofitted with an enclosure and mount for motion capture element. The apparatus may be located internal or external to the piece of sporting equipment and may show a visual marker for use in visually obtaining motion in combination with electronically detected motion obtained with the motion capture sensor. For example, the outer portion of the enclosure may display a visual marker on the outer portion while the inner portion of the enclosure may be located on or within a shaft or grip in the handle portion of the equipment for example. In one or more embodiments, the grip may extend beyond the shaft and couple or aid in the coupling of the motion capture element with the shaft. One or more embodiments of the grip may include a grip that may roll down from the sides of a motion capture element to enable the motion capture element to be accessed without removing the grip from the shaft. The mount is configured to hold the enclosure to the piece of equipment wherein the enclosure holds the electronics and/or a visual marker. Embodiments of the invention do not require modifying the equipment, for example the baseball bat, tennis racquet, golf club, or other stick based equipment to include threads within the shaft. The apparatus may be flush mounted with the normal end of the equipment or have any desired length of extension from the end of the equipment. The mount also allows for the battery to be easily removed and replaced, for example without any tools. Other embodiments may make use of micro harvesting of energy to recharge batteries internal to the enclosure.

[005] One or more embodiments of the mount include a shaft enclosure and expander that may be coupled with an attachment element, for example a screw that is aligned along an axis parallel to the axis of the shaft of the handle-based piece of equipment. The shaft enclosure and expander are situated within the handle portion of a handle-based piece of equipment such as a baseball bat, hockey stick, lacrosse stick, or golf club and engage in inner portion of the shaft or grip for example. In one or more embodiments, the screw is then rotated to move the shaft enclosure and expander together, which thus forces legs of the shaft enclosure in a direction orthogonal to the axis of the shaft. The force of the shaft enclosure against the inner wall of the shaft thus couples the shaft enclosure to the shaft non-permanently, for example based on the coefficient of static friction therebetween. After the shaft enclosure and expander are brought close enough together via the attachment element to securely couple the mount to the shaft or inside portion of a grip that is coupled to the shaft, then either the electronics package or a weight element is coupled with the shaft enclosure. In one or more embodiments, the weight element may weigh the same or approximately the same as the motion capture element so that there is no difference in weight to the piece of equipment with or without the motion capture element. In addition, certain sports may not allow the piece of equipment to be instrumented during match play. Embodiments of the weight element require no modification of the equipment. A cap is coupled with the shaft enclosure in either case, which provides a cover for the weight element or electronics package and which may include a visual marker and/or logo on the cap. Any other method or structure that enables a non-permanent mount of the apparatus that requires no modification of the shaft is in keeping with the spirit of the invention. Other embodiments may make use of a spear collet that enables coupling of a motion capture sensor with this type of mount to a stick or handle- based piece of equipment having a small hole in the end of the rubber grip on the handle. Other embodiments may utilize a shock puck that surrounds the enclosure and absorbs sudden shocks to the motion capture sensor within the enclosure, or otherwise dampens vibrations from the piece of equipment. Other embodiments may couple with helmets to obtain concussion related acceleration data, or obtain motion data related to board based sports such as snowboards, surfboards, skateboards as well as skis.

[006] If the electronics package is installed, then generally a positive battery contact, printed circuit board (PCB), an insulator or insulative spacer, with negative electrical contact and battery may be installed between the shaft enclosure and cap. The electronics that may be coupled with the PCB for example may include active motion capture electronics that are battery powered, passive or active shot count components, for example a passive or active radio frequency identification (RFID) tag. Embodiments of the electronics may include motion capture accelerometers and/or gyroscopes and/or an inertial measurement unit along with wireless transmitter/receiver or transceiver components. The RFID tag enables identification of the specific piece of equipment, for example to determine which piece of equipment specific motion capture data is associated with. Identification information for example enables golf shots for each club associated with a golfer to be counted. Golf shots may optionally be counted via an identifier associated with motion capture electronics on the golf club in conjunction with a mobile computer, for example an IPHONE® equipped with an RFID reader that concentrates the processing for golf shot counting on the mobile computer instead of on each golf club. Optionally a wireless antenna may be coupled with the cap or alternatively may be implemented integral to the PCB as desired. In one or more embodiments, the antenna may be implemented as a Bluetooth ® antenna embedded in an external portion of the enclosure, for example embedded in epoxy on an outer portion of the enclosure to maximize antenna coverage. One or more embodiments of the invention may also include a Global Positioning System (GPS) antenna. The GPS antenna may be mounted on the printed circuit board or may be located separate from the printed circuit board. One or more embodiments of the invention may also directly or indirectly communicate with any other sensors coupled with the club including motion analysis capture elements, strain gauges or any other type of sensor coupled for example with the golf club head. One or more embodiments of the invention may also utilize a battery coupling that attaches the battery to the shaft enclosure so that when the cap is removed, the battery does not fall out, unless intended. Embodiments may also utilized spring based electrical contacts to prevent loss of electrical conductivity under high acceleration.

[007] As previously stated, one or more embodiments may include a weight element that is interchangeable with the electronic package in the mount. The electronics package may be removed for example to comply with any sporting rules that do not allow instrumented sporting equipment. For example, USGA Rule 14-3 on Artificial Devices prohibits any "unusual device", for example under 14-3(b) "For the purpose of gauging or measuring distance". Any embodiment of the electronics package including a GPS receiver may thus be removed prior to match play for example and replaced with a weight element to minimize the weight difference. For example, the weight element may for example weigh close to or the same as the electronics to minimize overall instrumented versus non-instrumented weight differences of the golf club. In addition, a manufacture may provide the mount on each club with a small weight for example, that is removed when the golfer decides to upgrade the club to include active instrumented electronics or passive shot count elements that weigh the same amount. The net effect on the club dynamics for swing then is negligible. In one embodiment, the plastic portion of the mount weighs 5.7 grams and the battery weighs 3 grams while the screw weighs 1.9 grams. Thus the mounting components have minimal weight and by selecting a weight element of the same weight of the electronics package, or elements within the shaft enclosure and cap that are replaced by the weight element, the golfer feels no change in club weight when upgrading to an instrumented club. The same weight element may be utilized with respect to embodiments of the invention in all other sports and pieces of equipment used in those sports, as one skilled in the art will appreciate.

[008] The visual marker may be mounted on the cap for use with visual motion capture cameras. An equipment number may also be displayed on in a display area of the cap to indicate which type or specific piece of equipment is associated with the motion capture sensor, e.g., a club number is associated with the golf club. Embodiments of the visual marker may be passive or active, meaning that they may either have a visual portion that is visually trackable or may include a light emitting element such as a light emitting diode (LED) that allows for image tracking in low light conditions respectively. This for example may be implemented with a graphical symbol or colored marker at the cap of the mount on the shaft at the end of the handle for example. Motion analysis may be performed externally, for example using a camera and computer system based on the visual marker in any captured images. The visual data may also be utilized in motion analysis in combination with any wireless data from any installed electronics package.

[0050] An enclosure and mount for motion capture element will now be described. In the following exemplary description numerous specific details are set forth in order to provide a more thorough understanding of the ideas described throughout this specification. It will be apparent, however, to an artisan of ordinary skill that embodiments of ideas described herein may be practiced without incorporating all aspects of the specific details described herein. In other instances, specific aspects well known to those of ordinary skill in the art have not been described in detail so as not to obscure the disclosure. Readers should note that although examples of the innovative concepts are set forth throughout this disclosure, the claims, and the full scope of any equivalents, are what define the invention. One skilled in the art will recognize that embodiments of the invention may be utilized in any equipment capable of coupling with the apparatus. This includes any piece of sporting, exercise or medical rehabilitation equipment, for example a baseball bat, hockey stick, lacrosse stick, helmet, skateboard, ski, snowboard, surfboard, golf club, tennis racquet, weight training bar, or any other equipment capable of movement. The apparatus may be located internal or external to the piece of sporting equipment and may show a visual marker for use in visually obtaining motion in combination with electronically detected motion obtained with the motion capture sensor. For example, the outer portion of the enclosure may display a visual marker on the outer portion while the inner portion of the enclosure may be located on or within a shaft or grip in the handle portion of the equipment for example.

[0051] Figure 1 illustrates an embodiment of the invention 100 alone in perspective view and as mounted in a shaft of a piece of movement equipment, for example a baseball bat, hockey stick, lacrosse stick, golf club, tennis racquet or any piece of equipment having a handle near shaft 110 as shown in cutaway view. Embodiments enable a mount for a new piece of equipment or that can be retrofitted in an existing piece of equipment. The mount may be located in the handle portion of the shaft, or for example within a grip that is to be attached to the shaft, and is configured to hold electronics and/or a visual marker.

[0052] Figure 2 illustrates an embodiment of the invention broken into an exploded view of the main components along with the shaft handle and blow up views of the major components in transparent shading. One or more embodiments of the mount include enclosure or shaft enclosure 220 and expander 210 that may be coupled with an attachment mechanism, for example a screw aligned along an axis parallel to the axis of the shaft. The shaft enclosure and expander are situated within the handle, i.e., shaft 110. In one or more embodiments, the screw is then rotated to move the shaft enclosure towards the expander, which thus forces legs of the shaft enclosure in a direction orthogonal to the axis of the shaft. The force of the shaft enclosure against the inner wall of the shaft thus couples the shaft enclosure to the shaft based on the coefficient of static friction therebetween. Any other mechanism of coupling the shaft enclosure to a shaft in a non-permanent manner is in keeping with the spirit of the invention. After the shaft enclosure and expander are brought close enough together via the screw to securely couple the mount to the shaft, then either the electronics package or a weight element that may for example weigh the same as the electronics, is coupled with the shaft enclosure. Cap 230 is coupled with the shaft enclosure in either case, which provides a cover for the weight element or electronics package and which may include a visual marker and/or logo on the cap. One or more embodiments of the electronics package are removable to comply with any sporting rules that do not allow instrumented sporting equipment for example. Any other method or structure that enables a non-permanent mount of the apparatus that requires no modification of the shaft is in keeping with the spirit of the invention.

[0053] Optionally, an identification element or ID sticker, for example an RFID tag may be mounted within the enclosure, cap, or any other portion of the apparatus, for equipment identification, or shot count functionality. The identification element may also be implemented integral to, or coupled with the PCB in any manner as desired.

[0054] If the electronics package is installed, then generally a positive battery contact, printed circuit board or PCB, an insulator or insulative spacer, with negative electrical contact and battery may be installed between the shaft enclosure and cap. Optionally, a wireless antenna and/or GPS antenna may be coupled with the cap or alternatively may be implemented integral to the PCB as desired. Also see Figs 3A-C, 4, 4A-D and 9 for more detailed views.

[0055] Figure 3A illustrates a detailed cutaway view of the main components of an embodiment of the invention, specifically expander 210, shaft enclosure 220 and cap 230. Figure 3B illustrates a detailed cutaway view showing negative battery contact 450, also shown in full in exploded view in Figure 4. Figure 3C illustrates a detailed cutaway view showing positive battery contact 420, also shown in full in exploded view in Figure 4. Optional O-ring indentation 310 on shaft enclosure 220 provides a potential well for O-ring 320 to be located. Different size O-rings may be utilized to provide a secure fit on the end of shaft enclosure 220 on the end near cap 230.

[0056] Figure 4 illustrates an exploded view "A" of the main mount components, namely expander 210, shaft enclosure 220 along with screw 410, positive battery contact 420 and battery 430, while view "Bl" shows a top oriented view of the insulator 440, negative battery contact 450, electronics package 460, here a printed circuit board or PCB and cap 230, while view "B2" shows a bottom oriented view of the same components shown in view "B l". The left portion of shaft enclosure 220 shows extensions or "legs" that allow for the shaft enclosure to radially expand when expander 210 is pulled along the axis shown by screw 410, when screw 410 is rotated. To keep expander 210 from simply rotating when screw 410 is rotated, expander 210 may include a protrusion (shown on the left side of the expander) that aligns in a slot formed by two of the shaft enclosure's legs. In this manner, expander 210 is pulled along the axis of the screw without rotating along that axis. Electronics package 460 for example may include active motion capture electronics that are battery powered, passive or active shot count components, for example a passive or active RFID tag, which for example may be coupled with electronics package 460 or for example coupled with insulator 440. In addition, a GPS antenna may also be coupled with electronics package 460 or cap 230 (see Fig. 9A). Embodiments of the electronics may include motion capture accelerometers and/or gyroscopes and/or an inertial measurement unit along with wireless transmitter/receiver or transceiver components. The RFID tag enables golf shots for each club associated with a golfer to be counted. The RFID tag may be coupled with any component shown as RFID tags are tiny, for example cap 230 or shaft enclosure 220 or electronics package 460, or any other element. Golf shots may optionally be counted via an identifier associated with motion capture electronics on the golf club in conjunction with a mobile computer, for example an IPHONE® equipped with an RFID reader that concentrates the processing for golf shot counting on the mobile computer instead of on each golf club.

[0057] The visual marker may be mounted on cap 230, shown as a circle with dots in view Bl may be utilized with visual motion capture cameras. An equipment number, for example a golf club number may also be displayed on in a display area of the cap to indicate which club number is associated with the golf club, which is shown as a small circle with a number in it in view Bl . Embodiments of the visual marker may be passive or active, meaning that they may either have a visual portion that is visually trackable or may include a light emitting element such as a light emitting diode (LED) that allows for image tracking in low light conditions respectively. This for example may be implemented with a graphical symbol or colored marker at the cap of the mount on the shaft at the end of the handle for example. Motion analysis may be performed externally, for example using a camera and computer system based on the visual marker in any captured images. The visual data may also be utilized in motion analysis in combination with any wireless data from electronics package 460.

[0058] Figure 4A illustrates an exploded view "A" of the main mount components of a second embodiment of the invention, namely expander 210a, with ribs slightly offset with respect to expander 210 of Figure 4. In addition, Figure 4A also shows a second embodiment of shaft enclosure 220a having coupling elements that enable second embodiment of insulator 440a to securely couple to shaft enclosure 220a without falling out if the mount is turned upside down for example. In this embodiment, insulator 440a holds battery 430 inside while providing access to the battery so that positive battery contact 420a and negative battery contact 450a can make electrical contact with battery 430. View "B" shows a bottom- oriented view of the insulator, positive and negative battery contact, electronics package, here a printed circuit board or PCB and cap. Weight element 490 can be any shape so long as weight element 490 fits within, or couples in any direct or indirect manner with shaft enclosure 220 or 220a and cap 230 for example. Weight element 490 can be made to weigh as near as desired to the weight of the components that it replaces, for example to comply with any sporting rules that do not allow instrumented sporting equipment, e.g., during competition. Weight element 490 can also be utilized with the embodiment shown in Figure 4 as one skilled in the art will appreciate.

[0059] Figure 4B illustrates a perspective view of shaft enclosure 220a and insulator 440a of the second embodiment of the invention of Figure 4A along with the positive and negative battery contact 420a and 450a respectively (situated above holes in insulator 440a) along with battery 430 that is internally held within insulator 440a. Insulator 440a includes for example snap components, e.g., coupling elements 441 that couple with coupling elements 221 of shaft enclosure 220a so that insulator 440a and hence battery 430 do not fall out when the cap is removed. To remove insulator 440a and hence battery 430, tab 442 may be engaged with for example a finger, screw driver or other implement to disengage coupling elements 441 from coupling elements 221. Alignment component 443 enables rotational alignment of the insulator with the shaft enclosure.

[0060] Figure 4C illustrates a perspective view of the insulator along with the positive and negative battery contact 420a and 450a respectively, and battery 430. Coupling elements 441 are shown on the top and bottom in the written page, however any type of coupling element may be utilized in keeping with the spirit of the invention as desired.

[0061] Figure 4D illustrates a perspective close-up view of positive battery contact 420a. In one or more embodiments of the invention, the positive and negative battery contacts may utilize the same structure. Any type of positive and negative battery contacts may be utilized so long as they maintain electric connection between the battery and electronics package.

[0062] Figure 4E illustrates a top view of an embodiment of insulator 440a that is configured to house a battery along with specific exemplary dimensions. To remove insulator 440a and hence the battery within insulator 440a, tab 442 may be engaged with for example a finger, screw driver or other implement to disengage coupling elements 441 from the coupling elements shown for example in Figure 4B. In this figure, the numbers represent millimeters, and angle tolerances are within 2 degrees. As shown, this embodiment of insulator 440a is configured to house a 6.4 mm battery. Although not required for distribution in some countries, one or more embodiments of insulator 440a may be constructed to be compliant with EU Directive 2002/95/EC (RoHS) and EU Directive 2002/96/EC (WEEE). Embodiments may alternatively be constructed to be compliant with any other electrical or manufacturing standards as desired.

[0063] Figure 4F illustrates a first side of the embodiment of the insulator of Figure 4E. See also Figure 4H for the cross section view. Figure 4G illustrates a second side of the embodiment of the insulator of Figure 4E. Figure 4H illustrates a cross section view "A" of Figure 4F. Figure 41 illustrates a bottom view of the embodiment of the insulator of Figure 4E.

[0064] Figure 5 illustrates a close up perspective view of the electronics package 460 or PCB and associated positive contact 510 and negative contact 520 that are configured to make an electrical connection with the positive battery contact 420 and the negative battery contact 450 respectively. See also Figure 4 for an exploded view of the relative positioning of the components shown in this figure.

[0065] Figure 5 A illustrates a second embodiment of positive battery contact 420b located in the shaft enclosure. This embodiment is symmetrical in that there are two opposing sets of upward projections from the base plane that contacts shaft enclosure 220. One of the opposing sets of upward projections of positive battery contact 420b are slightly wider and are positioned within areas on shaft enclosure 220 to allow for radially aligning positive battery contact 420b with respect to shaft enclosure 220.

[0066] Figure 6 illustrates a close up perspective view of cap 230 with electronics package 460 or PCB and negative battery contact 450 coupled with insulator 440 showing along with a coupling element, here four coupling points 610 (with only the top two shown with reference number 610 with the inside portions visible, while the opposing two have only the initial slot openings in the cap visible), and alignment element 620.

[0067] Figure 6A illustrates a second embodiment of the negative battery contact 450b having faceted surfaces as shown from the bottom side of insulator 440. Figure 6B illustrates the embodiment of Figure 6A as shown from the top side of the insulator. The right portion of negative battery contact 450b as shown may be folded over to engage insulator 440 while the opposing end of negative battery contact 450b may freely travel in a slot provided in insulator 440. The slot allows for the negative battery contact 450b to flatten, and hence travel in the slot, based on the force generated by placing the battery against negative battery contact 450b.

[0068] Figure 7 illustrates a close up perspective view of the cap and alignment element. Alignment element 620 allows for the angular alignment of insulator 440, and electronics package 460 that have indents on their sides to engage the alignment element 620. (See Fig. 4). By aligning insulator 440 and electronics package 460 with cap 230, positive battery contact 420 and negative electrical contact 450 are also aligned rotationally since they couple to respective components non-rotationally, for example.

[0069] Figure 8 illustrates a cutaway view of a second embodiment of electronics package 460a in longitudinal form along with a second embodiment of a coupling element. Any other orientation of electronics is in keeping with the spirit of the invention so long as the mount is configured to hold the desired electronics package. Embodiments of the invention do not require modifying the piece of equipment, for example to include threads within the shaft. Embodiments of the invention also can be flush mounted with the normal end of a shaft or have any desired low profile extension from a non-instrumented club. Embodiments of the invention generally utilize a mount that is separate from the electronics so that the electronics package can be easily removed and replaced, or so that the battery can be easily removed and replaced, for example without any tools. As shown in this embodiment, a different coupling mechanism is used versus coupling points 610, namely threads 810 that engage shaft enclosure 220, which in this embodiment has corresponding threads.

[0070] Figure 9 illustrates an embodiment of wireless antenna 910, configured to mount within cap 230 as shown in the right portion of the figure. Alternatively, the wireless antenna may be coupled with the electronics package 460 or may include any conductive element in any shape that can radiate electromagnetic energy.

[0071] Figure 9A illustrates an embodiment of the cap having two antennas, a wireless antenna, for example a BLUETOOTH® antenna and a GPS antenna 920. The GPS antenna is optional and may be mounted in cap 230 as wireless antenna 910 is, or may be implemented in a different form factor or coupled with the PCB in any direct or indirect manner as one skilled in the art will appreciate. See also Figure 18 for another embodiment of the antenna configuration.

[0072] Figure 10 shows an embodiment of shaft enclosure 220b with angled area 1001. Shaft enclosure 220b couples with cap 230 as is shown in the right portion of the figure. Any other embodiment of the shaft enclosure detailed herein may be utilized on a shaft having a grip that either includes a hole or that does not include a hole and that wraps partially or fully around the motion capture element.

[0073] Figure 1 1 shows grip 1 101, having a hole in the top of the grip that allows for the grip to be rolled down the shaft as is shown at area 1101a. This enables cap 230 to be exposed, removed or otherwise accessed without removing the grip from the piece of equipment for example.

[0074] Figure 12 shows grip at area 1101b rolled back over angled area 1001 and onto the side portions of cap 230. This enables the end of the cap 230 to be seen through the hole in the end of the grip, and enables the grip to provide extra support for the motion capture element.

[0075] Figure 13 illustrates a spear collet cutaway view of an embodiment of the invention. Spear 1301 couples enclosure 220 with the hole 1302 in the handle-based piece of equipment. The spear has a narrower portion shown at the hole, but this is not required so long as the spear is capable of holding enclosure 220 to the handle.

[0076] Figure 14 illustrates a rear perspective view of the embodiment shown in Figure 13. As shown, visual marker 1401 for motion capture detection via visual methods is shown on cap 230 of enclosure 220.

[0077] Figure 15 illustrates a handle-based embodiment of the invention. As shown, visual marker 1401 is visible and in one or more embodiment may contain high contrast or active elements to enable easier visual detection of the orientation and/or motion of the motion capture sensor for example with a camera. The embodiment shown may be coupled with a baseball bat or other handle based piece of equipment for example.

[0078] Figure 16 illustrates a structural view of another handle-based embodiment of the invention. As shown, cap 230, which covers the enclosure, is isolated from the piece of equipment via shock puck 1601. Shock puck 1601 may include any material that dampens or otherwise limits G-forces from the piece of equipment to assert force on the motion capture sensor.

[0079] Figure 17 illustrates another handle-based embodiment of the invention. As shown, uncovered portion 1701 may be utilized to house an antenna external to the inside portion of the enclosure. In one or more embodiments, areas 1702 may be made from any material that enables radio frequency waves to emanate from the internal volume of the enclosure. Alternatively, or in combination, the uncovered portion may provide an area for a small antenna that is then covered for protection as is shown in the next figure.

[0080] Figure 18 illustrates the handle-based embodiment of the invention of Figure 17 showing the location of the antenna on the outer portion of the enclosure. As shown, antenna 1801 may be placed in the uncovered portion 1701 as shown in Figure 17, which is shown in this figure partially filled with epoxy. Two holes may be drilled through the cap to provide feed lines for antenna 1801 and also for ground point 1802. The antenna and ground point may be covered as is shown in the next figure. Embodiments of the enclosure that are metallic and for example behave as an electromagnetic shield may utilize this type of antenna and provide for an extremely durable enclosure and exceptional antenna coverage for example.

[0081] Figure 19 illustrates the embodiment of Figure 17 with the antenna shown in Figure 18 covered with non-conductive material. As shown, the uncovered portion shown in Figure 17 is covered at 1901 for example, and flush with the other portions of the cap to provide a finished cap for the enclosure that provides maximal antenna covered, while still providing a visual marker for bot electronic and visual motion capture sensing capabilities.

[0082] Figure 20 illustrates a cutaway view of an embodiment of the invention coupled with a piece of equipment having a handle. As shown, shock puck 1601 surrounds enclosure 220 to provide high G-force shock protection to the internal components of the motion capture sensor. One or more embodiments of the invention may be covered with an outer protective area 2001, which may be transparent in one or more embodiments.

[0083] Figure 21 illustrates an embodiment of the invention configured to couple with a helmet. As shown, enclosure 220 couples with mount 2101 that includes a half circle opening for example that may be fit around a helmet facemask tube or grill. Screw 2102 may be tightened to close the gap between the mount and the screw backing to couple enclosure 220 to a helmet.

[0084] Figure 22 illustrates the embodiment shown in Figure 21 coupled with the helmet. As shown, enclosure 220 is coupled with helmet via facemask tube or grill 2201 as per the elements shown in Figure 21. Any other method of coupling the enclosure with a helmet is in keeping with the spirit of the invention.

[0085] Figure 23 illustrates a close-up of the embodiment shown in Figure 22. Visual marker 1401 is shown on the outside portion of the helmet for use in capturing motion with an external camera for example.

[0086] Figure 24 illustrates a perspective view of an embodiment of the invention coupled with a skateboard truck. As shown, enclosure 220 couples with or otherwise includes mount 2401 that is configured to couple with the existing screws of a skateboard truck mount 2402. Thus no extra holes are required for mounting an embodiment of the invention to a skateboard. The same configuration may be reshaped to fit holes associated with a snowboard binding or other planar oriented piece of equipment including skis as is shown in the next figure.

[0087] Figure 25 illustrates an embodiment coupled with planar equipment. As shown, enclosure 220 may be mounted along with the snowboard binding 2501 of a snowboard. In one or more embodiments, the enclosure may be coupled with the snowboard mount itself, or utilize a flat version of mount 2401 to couple with an existing screw used to mount the binding. As shown in the lower portion of the figure, enclosure 220 may mount on or near the top of the surfboard or on the underside of the surfboard near the skeg 2502 since surfboards may be made from materials that enable the transmission of electromagnetic waves. In one or more embodiments enclosure 220 may be housed in streamlined mount 2503 and adhesively mounted to any planar equipment, for example the snowboard, surfboard or skis. Streamlined mounts provide low wind or water drag and minimize interference with external objects for example.

[0088] While the ideas herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
