A somatosensor device comprises a handle (10) having a hollow free end (130) to form a cavity (133) with an opening in a tail end surface (131); a wireless charging circuit board (30) overlapped on the tail end surface (131); a tracker (50) fixed on the wireless charging circuit board (30) and electrically connected with same, the tracker (50) inserted into the cavity (133) as the wireless charging circuit board (30) is overlapped on the tail end surface (131); and an end cap (70) covered on the free end (130) of the handle(10), so as to seal the cavity (133) with the opening in the tail end surface (131). The configuration takes account of the sealability and wireless charging.

A swing analysis device for analyzing a swing of a ball hitting tool includes: an information input unit configured to receive input of acceleration information and angular velocity information detected by a sensor attached to the ball hitting tool; a posture calculation unit configured to calculate posture information of the ball hitting tool in the swing by applying a predetermined filter to the acceleration information and the angular velocity information; a correction unit configured to correct the posture information of the ball hitting tool in the swing based on the posture information of the ball hitting tool at a first time in the swing; and a swing information calculation unit configured to calculate a swing trajectory of the ball hitting tool based on the acceleration information and the posture information of the ball hitting tool corrected by the correction unit.

Training equipment includes a hollow shaft having a sidewall defining an internal cavity and at least one polymer material filling at least a portion of the internal cavity. The polymer material may fill the entire internal cavity of the hollow shaft. The polymer material may be a visco-elastic polymer material or polyurethane. A spacer or a filler may fill at least a portion of the internal cavity. A method of making weighted training equipment with a hollow shaft having a sidewall defining an internal cavity may include injecting a curable composition into at least a portion of the internal cavity. The method may further include curing the curable composition into a polymer material.

A firearm that provides a user with tactile biofeedback. The firearm includes a tactile reference feature that extends longitudinally along an exterior body surface and is formed with dimensions specifically tailored to harness the user's natural attributes of sensibility, proprioception, and neuromuscular memory to improve a user's accuracy.

Embodiments disclosed provide a solution to detect a rally in a sports game. One or more stroke actions or non-stroke actions are detected based on motion data detected by a sensor attached to a sports instrument of a user. Using a trained stroke classification model, each detected stroke action is classified into a plurality of classes. Additionally, a determination is made whether each detected non-stroke action is an intentional special user action. The determination whether a non-stroke action is an intentional special user action is made based on a customized set of definitions defining one or more special user actions. One or more rallies are then detected based on the classified stroke actions and intentional special user actions.

Disclosed herein are improved wearable devices with sports implements (e.g., hockey stick, tennis racket, golf club, etc.). A wearable device can be worn on any suitable part of a user's body (e.g., foot, leg, arm, etc.) or, alternatively, over a device (e.g., shoe) already worn on the user. The wearable device can be permanently affixed to a sports implement or, alternatively, can be adaptable with a sports implement selectable from a set of interchangeable sports implements. Such interchangeability can be provided by a coupling mechanism that is configured to detachably couple the wearable device to the sports implement. The coupling mechanism can include a receiver base integrated to a body of the wearable device and a complementary accessory base of the sports implement.

A pole system for supporting a sports net, the pole system including a net post, a receiver pole, a support base, and a plurality of suction cups. The net post, designed for temporary attachment to the net, is partially received within the central area of the receiver pole. The support base, attached to the receiver pole, comprises outwardly extending base members, each ending with a suction cup for temporary ground attachment. The pole system, constructed from materials such as metal, plastic, fiberglass, or wood, can adapt to varying base member configurations. A threaded screw mechanism further ensures secure retention of the net post within the receiver pole. The invention offers a novel, efficient, and cost-effective solution for setting up sports nets, ensuring stability and ease of assembly.

A guy wire system for supporting a volleyball or badminton net having a split two-part end section, each part attachable to the ground.

A solution is provided to enhance motion detection and recognition of moving objects associated with various sports by embedding motion sensors into sports instruments such as tennis rackets, badminton rackets, baseball bats and golf clubs, that are swung in a three-dimensional (3D) space. A motion sensor device inserted and locked inside a sports instrument is configured to detect motions associated with movements associated with the sports instrument. The device is shaped to be inserted into a sensor housing attached to a selected location inside the sports instrument. The device includes a motion sensor for detecting motion associated with the movement of the sports instrument, a cover for protecting the motion sensor, and a locking mechanism attached to the sensor housing for locking the motion sensor inside the sensor housing.

Certain embodiments of the present disclosure describe a pole and base assembly. The pole and base assembly includes a pole with an upper engagement portion and a lower engagement portion that are biased toward each other. A base includes a socket to receive the pole and a channel that allows the lower engagement portion to pass through the base. The upper engagement portion is retained on the top surface of the base. When the lower engagement portion is passed through the socket and aligned with a locking portion, the biasing force causes the upper and lower engagement portions to clamp together around the base and lock the pole to the base.
