A system and method for measuring motion properties of a movable object, such as a sporting device, wherein the movable object has an embedded magnetized unit creating a magnetic field. A measurement device, having a first magnetic field sensor positioned a known distance away from a second magnetic field sensor, is positioned in the vicinity of the movable object's trajectory, whereby the first and second magnetic field sensors output signals when the movable object passes within their respective proximities. A control module, that is responsive to the output signals created by the magnetic field sensors, is configured to record the times of output signal events. The control module is further configured to calculate motion properties, such as the speed and rate of spin, of the movable object based upon the recorded times of various sensor output events and the known distance between the first and second magnetic field sensors.

According to the various features characteristics and embodiments of the present invention which will become apparent as the description thereof proceeds, the present invention provides partially fingered gloves and the use of said gloves, intended to increase the overall performance in sports activities including but limited to football and golf. Because of its unique finger configurations, grip enhancers, and/or its hand protective properties, the present invention makes a glove now operable on a football quarterback's throwing hand and on golfers dominant hand, for example.

A golf training device for use in a glove or under the ball of the foot or under the heel, which includes pressure sensors, a visual display which is flexibly connected to the sensors for adjusting the position to suit the wearer, and a controller programmed to provide visual feedback to indicate if the pressure is appropriate or not. For a glove the sensors are located on the palm at the junction with the first three fmgers. There are two or more sensors and for each sensor the controller can display by an appropriately coloured LED that the pressure detected by the sensor is too light, appropriate or too tight. For a shoe the sensors are located under the ball of the foot or the heel and the LEDs indicate whether the weight is appropriately on the ball of the foot or on the heel.

A method and system used to periodically clean dirt and oils deposited through normal use from the grip of a golf club and renew it to a near new condition is disclosed. The system for cleaning and restoring a golf club grip of a golf club comprises a generally elongated housing having a hinge for splitting open the housing lengthwise wherein an interior of said housing defines retaining channels and a generally tapered and trapezoidal cleaning and restoring device defining an elongated centrally located ridge along a top of said device. In use, the device is placed into the housing by inserting the device ridge into the housing channel for holding the device during use wherein the housing defines a latch allowing the housing to close shut and hold a golf club grip in place during use with the device.

The invention generally relates to a system and method for integrating physical, moving targets into a game, sport or other activity, including the specific method of how to track the moving target and the interaction of one or more users as the target moves. The system and method for integrating physical, moving targets into a game, sport or other activity enables a plurality of users to simultaneously attempt to hit a moving target in the field of play with a moving object while tracking the moving target and moving object using a combination of sensors located on or around the field of play and on or around the moving target and/or moving object.

The present invention is directed to a set of golf clubs comprising long irons, mid irons and short irons. The irons have a progressive horizontal CG location. Preferably, the long and mid irons have a face stabilizing bar and back panel and the CG is located between about 1 mm and 3 mm towards the hosel and the CG in the short irons is located between about 3 mm and 4 mm toward the hosel. Further the long and mid irons irons can have a plurality of apertures in the face stabilizing bar and/or the back wall.

An apparatus for golf training includes a wrist strap and a ring which are shaped and sized to be worn by a user. A cable extends between the wrist strap and the ring, and certain movements thereof are configured to provide an indication of improper swing form using an audible stimulus

Hole locations on a golf course are managed by identifying a plurality of physical golf greens and generating a course map that defines a perimeter of each green. Potential hole locations are identified for each green and associated with hole location coordinates. Each potential hole location is associated with a corresponding hole location score. A desired overall course score is identified and a set of golf hole locations for the plurality of physical golf greens is selected to provide the desired overall course score. The hole location coordinates of the selected hole locations are provided to a manager device to guide the cutting of golf holes on the plurality of physical golf greens.

Systems and methods providing statistical analytics of golf performance for coaching including text, tabular, graphic, and image-based outputs that include trends information for the golfer, all based upon actual golf play on course situations, wherein the golfer inputs shot data during play, without interrupting the flow of the game, and uploads the shot data for analytics and review online, and wherein all information related to a given user are reviewable by an authorized coach user through a web-based coach access account. The system is further operable to provide the coach user rights for providing corrective or instructive feedback to the user, including visual recommendations such as modified target areas.

A wrist worn muscle movement monitoring device includes a wrist strap; a sensor that responds to muscle movement at a wrist wearing the wrist strap; and monitoring circuitry connected to the sensor.
