A golf club simulation apparatus includes an elongate shaft housing having opposed lower and upper ends and defining an interior area. A club head member is coupled to the lower end of the shaft housing. A battery is situated in one of the club head member and the shaft housing. An input member configured to receive club selection data is coupled to an outer surface of the shaft housing and electrically connected to the battery. A mass variability assembly is electrically connected to the input member and includes a weight member situated in the shaft housing that is selectively movable therein according to the club selection data. An electronics module having an angular sensing sensor is situated in the club head member. A bend variability assembly is included in the shaft housing for selectively altering a feel characteristic of the shaft housing during a swing motion.

The present disclosure discloses a position changeable sensor which includes a main body and an attaching member. The position changeable sensor is disposed on an exercise equipment, and the main body is disposed in a selectable position on the exercise equipment. The main body includes at least one gravity sensor. The attaching member is disposed on the main body, and the attaching member is removably attached to the exercise equipment and the main body.

Enables coupling or retrofitting a golf club with active motion capture electronics that are battery powered, passive or active shot count components, for example a passive RFID, and/or a visual marker on the cap for use with visual motion capture cameras. Does not require modifying the golf club. Electronics package and battery can be easily removed and replaced, for example without any tools. May utilize a weight that is removed when inserting the electronic package in the mount, wherein the weight element may have the same weight as an electronics package, for no net change or minimal change in club weight. May be implemented with a shaft enclosure and expander that may be coupled with a screw aligned along an axis parallel to the axis of the shaft. May utilize non-permanently and/or friction coupling between the mount and shaft. Cap may include a visual marker and/or logo.

An apparatus for use with a sports racquet. The apparatus including a sensor to be carried by the racquet and an indicator in communication with the sensor to output a notification based on the number of hits by the racquet based on signals from the sensor.

Performance of a racket can be adjusted. A racket includes a grip, an annular frame that is provided with a plurality of through holes that penetrate from an inner circumferential face to an outer circumferential face, and a shaft that connects the grip and the frame in a shaft axis direction, the frame having a rear end side attachment part, on the outer circumferential face of the frame and on a side closer to the shaft in the shaft axis direction, where there is mounted a rear end side attachment to which a string tensely provided to the frame is routed, and the rear end side attachment being made of a material different from the frame.

The invention relates to a sports racquet having a head having a string bed is attached to two throat beams that extend continuously downward to a shaft having a handle. Each throat beam contains a bending zone in which the width of the throat beam parallel to the string bed and the width of the same throat beam perpendicular to the string bed gradually changes in equal, but opposite, dimensions such that the circumference of the throat beam remains substantially constant through at least the length of the bending zone or the length of the entire throat beam. Where the width of the throat beam parallel to the string bed is the widest and the width of the throat beam perpendicular to the string beg is the narrowest defines the flexible cross-section or flex point of the bending zone.

An assembly comprises a base and a housing having a longitudinal axis extending orthogonally from the base. A plurality of scoring wheels is mounted to the base in a stacked relationship and configured to rotate about the longitudinal axis, each scoring wheel having indicia comprising spaced apart markings on a circumferential surface about the longitudinal axis indicative of a score for a team or player in a game. The housing has side walls about the longitudinal axis obscuring the indicia on the scoring wheels arranged to form three spaced-apart apertures allowing the indicia to be readily seen, the three spaced-apart apertures comprising a first aperture and a second aperture spaced apart from the first aperture, and a third aperture located spaced-apart from and between the first aperture and the second aperture.
