A system that wirelessly integrates actual game equipment with a computer and the internet to allow players remotely located from one another to play a competitive real or simulated sports game such as golf. An individual player may opt to play solo or practice to improve basic sports techniques. The system includes, but is not limited to, golf clubs, and motion sensing devices, all containing circuits, contact and or noncontact motion sensors coupled with signal processing and radio frequency transmitter circuitry to wirelessly communicate game data performance information to a remote receiver-computer. The computer displays player information and visually simulates and controls a game between one or more local players or via the internet having similar equipment and remotely located from each other. This invention uses the electric field of a capacitive plate for sensing object proximity, motion, and geometry. More particularly, the invention relates to a system wherein the physical geometry in part of an object, and or its spatial orientation, motion, and an environmental change of state can be detected due to signal variances and or from a change in the dielectric of a capacitor array. The invention also uses the coupling of sports equipment and a computer to communicate information wirelessly to a remote computer, and thereby, if desired, to the internet. Standard golf clubs may be retrofitted with the sensors and associated circuitry to convert such clubs into smart clubs for use with the system. The system employs specially developed computer software to process player performance data, control game play, communicate game information between local and remote players, generate and control visual simulations, and display player performance information and dynamic motion parameters.

A golf club head has a body defining a ball striking face. The body further has a first leg extending away from the ball striking face and a second leg extending away from the ball striking face wherein a void is defined between the first leg and the second leg. The body further defines a cover that extends over the void. The golf club head may further have support structures and adjustable weight members.

Provided is an auxiliary apparatus for a golf putter including a coupling member detachably coupled to a shaft of the golf putter and a guide light emitting device coupled to the coupling member and configured to emit a guide light to help golf putting. The coupling member includes a first coupling member opened at upper and lower portions and one side thereof and detachably coupled to the golf putter through the opened space, and a second coupling member extending from the first coupling member and opened at upper and lower portions thereof, the second coupling member being configured to accommodate the guide light emitting device through the opened space. The guide light emitting device includes a housing, a battery located at one side inside the housing and configured to supply a power for operating the guide light emitting device, a light emitting unit configured to emit a guide light based on the supplied power, and a control unit configured to select a light emitting mode and control the light emitting unit so that the guide light is emitted to correspond to the light emitting mode. The guide light emitting device is detachably coupled in the opened space formed in the second coupling member and has a cylindrical shape elongated vertically, and the guide light emitting device is inserted into the second coupling member to be rotatable therein.

A golf putting training aid teaches a golfer to push the golf ball on the green during putting. The aid comprises a collar is carried by a golf club shaft. A bore extends vertically through the collar to receive a golf ball therein. The bore has a bottom opening facing downwardly. A flap is carried by the collar and extends into the bore and is displaceable to selectively retain and release the golf ball. An automatic ground actuated trigger is coupled to the flap and extending downwardly and rearward to contact the ground during fore swing of the golf club shaft to gravity release the golf ball onto the green and allow the golfer to push the golf ball with the golf club.

A wearable device for determining balance of a user is provided, comprising a gyroscope, an inertial measurement device, a memory storing instructions, and a processor configured to execute the instructions to perform operations, comprising receiving angular velocity measurements over a period of time from the gyroscope, receiving deviations from the second axis over the period of time from the inertial measurement device, weighting the deviations from the second axis based on directions associated with the deviations, receiving deviations from the third axis over the period of time from the inertial measurement device, weighting the deviations from the third axis based on directions associated with the deviations, and based on the angular velocity measurements, the weighted deviations from the second axis, and the weighted deviations from the third axis, determining an index associated with a left side of the user and an index associated with a right side of the user.

A golf putter alignment system has two alignment markers placed above the strike face of a putter head on the front top surface of the putter head. The alignment markers are centered about a midpoint that corresponds to the horizontal center of the strike face, with the distance between the centers of the alignment markers corresponding to the diameter of a golf ball. The alignment markers can be mounted on top of or integrally with the putter head to provide visual alignment markers on the front top surface. The alignment markers are formed from several materials with colors that contrast with the color of the front top surface.

Embodiments of systems, methods, computer-readable media and article of manufacture related to measuring, analyzing, and sharing golf swing and ball motion characteristics are generally described herein. Other embodiments may be described and claimed.

Provided is a digital putting diagnosis device for diagnosing putting, which is provided in a putter head of a golf putter, including: a 9-axis sensor unit for detecting position and movement of the putter head, the 9-axis sensor unit detecting rotation of the putter head in a roll direction, a pitch direction, and a yaw direction; a control unit for controlling the posture of the putter head at the time of addressing the putting and the swing path of the putter head during putting to be displayed in real time by using the detected signal of the 9-axis sensor unit according to the movement of the putter head; and a display unit for displaying the posture of the putter head and the swing path of the putter head under the control of the control unit.
