A system comprises an inertial sensor, a processor connected to the inertial sensor, and a memory device connected to the processor. The inertial sensor includes an accelerometer with three degrees of freedom in acceleration and has three degrees of freedom in rotation. The processor is configured alone or in combination with a linked microprocessor to generate stroke profiles describing acceleration and rotation based on signals from the accelerometer, and the memory device is configured to store the stroke profiles.

A sporting equipment is disclosed. The sporting equipment may include a head, and at least one of a handle and a shaft extending from the head. The head and the at least one of the handle and the shaft may be a monolithic structure having at least one continuous fiber passing from the head to the at least one of the handle and the shaft.

A sporting equipment is disclosed. The sporting equipment may include a harness, and a protective plate. The protective plate may be integrally formed with the harness from a plurality of fibers that are continuous from the harness into the protective plate.

A sporting equipment is disclosed. The sporting equipment may include an elongated platform configured to support a user and being fabricated from matrix-coated fibers. The sporting equipment may also include a sensor integrally fabricated into the platform and connected to the matrix-coated fibers.

A sporting equipment is disclosed. The sporting equipment may include a barrel, an action connected to a base end of the barrel, and a stock connected to the action opposite the barrel. At least two of the barrel, the action, and the stock are fabricated from a plurality of fibers.

A method and system to deliver biomechanical feedback utilizes three major elements: (1) multiple hardware data capture devices, including optical motion capture, inertial measurement units, infrared scanning devices, and two-dimensional RGB consecutive image capture devices, (2) a cross-platform compatible physics engine compatible with optical motion capture, inertial measurement units, infrared scanning devices, and two-dimensional RGB consecutive image capture devices, and (3) interactive platforms and user-interfaces to deliver real-time feedback to motions of human subjects and any objects in their possession and proximity.

An apparatus to keep score during a tennis or other racket match being affixed to a set of racket strings, the apparatus includes a housing having a perimeter, a front surface and a rear surface, each surface configured with indicia to indicate game and set score, said perimeter includes a groove therearound to removeably affix housing to the racket strings, wherein the housing includes a pair of stacked polygon apertures, the front polygon being a hexagon and the second being a pentagon, and a pair of stacked pluggable dials, the front polygon being a hexagon and the second being a pentagon, wherein said pluggable dials include a finger grip, indicator, base or stop, and annular male female snap, and thus to facilitate keeping game and set score during a match and to provide vibrational dampening.
