A measuring device includes a base station, a weight station unit and a controller. A mount station unit is connected to the weight station unit and has first and second mounting bases connected by a swing arm. The first mounting base is moveably supported on the first weight scale, and the second mounted base is moveably supported on the second weight scale. An adjustable holding part is disposed at one end of the first mounting base and a support is disposed at another end of the first mounting base adjacent the swing arm. A sports article is mountable on the first mounting base between the adjustable holding part and the support.

A basketball training assembly includes a cart that is rollable along a support surface. The cart can be positioned a selected distance from a basketball hoop on a basketball court. A lift is coupled to and extends upwardly from the cart. The lift is turned on to extend a predetermined distance upwardly from a home position on the cart. A barrier is coupled to the lift and the lift lifts the barrier the predetermined distance from the home position when the lift is turned on to simulates a defensive basketball player. A plurality of motion sensors is each coupled to the barrier to sense motion of a basketball player approaching the barrier. The lift is turned on when one or more of the motion sensors senses motion. Thus, the lift lifts the barrier when the basketball player approaches the barrier to take a shot during basketball practice.

Articles of sports equipment, such as striking implements (e.g., sticks) and wearable articles (e.g., skates, helmets) for playing hockey or other activities, in which at least one of the characteristics (e.g., stiffness) of the articles of sports equipment is adaptable and can be altered during use of the sports equipment, such as by comprising an alterable component coupled to a controller, by comprising an alterable component that is autonomously alterable, and/or by an alterable component that can be altered in response to a command of a remote device.

A swing analysis method includes acquiring measurement data measured by an inertial sensor in a swing motion with a golf club, and calculating torque data indicating a temporal change of a torque exerted on the golf club by analyzing the measurement data using a head speed coordination system having a first axis including a speed vector of a head of the gold club, a second axis being orthogonal to the first axis and extending along a shaft of the golf club, and a third axis orthogonal to both the first axis and the second axis.

A Bluetooth chip designed to track proximity and play a sound, along with an accelerometer, that is embedded inside of a golf ball is disclosed. The technology inside the balls allows it to be found quickly through proximity and sound, and the app gives a golfer helpful analytical data.

A golf club head with an interchangeable or reversible sole rail system having a rail member configured to be received within one or more channels formed on the club head. The rail system allows the player to employ rails along a surface of the club head to improve the interaction between the club head and the ground during the swing.

A system for sensor-based tracking of participants of a sporting activity is provided. In some implementations, the system performs operations comprising determining, based on sensor data (e.g., information indicative of at least a location of a plurality of tracked participants and a location of a tracked object), a first probability of a team successfully scoring. The operations further comprise determining, in response to detecting an action which at least changes the location of the tracked object, a second probability of the team (or an opposing team (successfully scoring, and assigning, based on a difference between the first probability and the second probability, at least a portion of the difference among one or more of the plurality of participants. Related systems, methods, and articles of manufacture are also described.

A multifunctional self-contained system that wirelessly integrates actual sports equipment with a computer providing critical feedback to improve all aspects of a player's game, and also allows players to play an actual competitive real or visually simulated game or sports with one or more players. Therefore, an individual player may opt to play solo or practice to improve basic golfing skills and techniques. The system includes sport implements that include, but are not limited to, smart golf clubs, a golf ball receptacle and a golf club motion sensing device, all containing circuits with contact sensors and or motion sensors coupled with signal processing and radio frequency transmitter circuitry to wirelessly communicate game status and performance parameters to a remote receiver and computer. The computer then optionally displays important parameters such as proximity of a sports implement contact face to an object, the impact of a sports implement with a sports equipment item, wherein the contact force, contact time, impact location, face angle, spatial orientation of a sports implement in motion, and the subsequent energy, velocity, and trajectory of game projectile such as a golf ball. The sports implements can be further equipped with motion sensing devices, and its motion and swing trajectory is visually simulated on the computer display. Standard sport implements which include, but are not limited to, golf clubs may be retrofitted with the device sensors and associated electronic 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 to players, generate and control real-time audio-video visual simulations, and display player performance information.

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.
