A basketball shooting apparatus is disclosed. The apparatus comprises a backboard and rim assembly having a backboard positioned in parallel with ground and ceiling and a rim member attached in perpendicular to the backboard. The apparatus further comprises an assistive learning system (ALS), a frame, and a motion tracking system. The ALS is attached to the backboard to perform score-keeping, intelligent instruction providing, and mode changing during shooting practice. The frame comprises a net attached at its peripheral ends to support the backboard and rim assembly and ALS. The motion tracking system comprises one or more tracking devices positioned on and/or around a user capable of capturing, inferring, or allowing the inference of three-dimensional motion from the user's arms, hands and wrists. The ALS provides visual feedback regarding the user's shooting form via a visual display, thereby training the user at their learning phase of developing proper shooting techniques.

An exercise form analysis and feedback system (EFAF) including at least one sensor, at least one local movement data receiver, an analysis and feedback processing unit (AFPU) and a feedback display. The EFAF system of the present invention obtains lift movement data through the one or more sensors as lift movements are performed. This lift movement data may, in turn, be transmitted to one or more local movement data receivers such that the AFPU may operate on the lift movement data to provide real-time or near real-time form/technique feedback to the user via a feedback display. The system of the presentation invention uses machine learning techniques to provide feedback on lift quality aspects based on data associated with previous lifts and external data as applicable.

A let detection system includes a sensor including an accelerometer attached to a tennis net. The sensor is in wireless communication with an umpire device able to send a message to the sensor, wherein the message causes the sensor to calibrate and begin monitoring for a let. The sensor determines a three-dimensional (3D) vector representing the gravity acting on the sensor as a baseline. When the sensor detects vertical acceleration of the net relative to the baseline and the vertical motion is above a preset threshold, the sensor automatically transmits a let notification message to the umpire device.

A method includes obtaining position information relating to an object in a sporting event, determining, based on the position information, that a start event has occurred, wherein the start event indicates a start of play of the sporting event, and generating, according to a result of the determination, an instruction to start storing position information relating to the object.

In a first aspect, a method for monitoring a golf swing is provided that includes coupling a mobile telephone to a golf club and employing the mobile telephone coupled to the golf club to monitor acceleration of the mobile telephone as the mobile telephone swings while a user swings the golf club, collect acceleration information based on the monitored acceleration of the mobile telephone as the mobile telephone swings, analyze the collected acceleration information to determine one or more characteristics of the golf swing based on the collected acceleration information, and output information regarding the one or more characteristics of the golf swing on the display of the mobile telephone. Numerous other aspects are provided.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

Sleeves for improving performance and control are disclosed. The sleeves are constructed for use on the fingers, wherein each sleeve is constructed in some embodiments with grip zones that match areas of the finger to ensure improved grip while maintaining flexibility, compression, protection, and material durability. Each grip zone is positioned to ensure that fingers are able to naturally bend without impeding grip performance. A spine on a rear of the sleeve ensures material durability, limits over extension, and provides padding and protection.

Provided herein are embodiments of a barbell spotting apparatus having all the benefits of a free-floating, unconstrained barbell in both the horizontal and vertical axes with the safety of a dedicated spotting mechanism, while addressing safety, noise, and space concerns raised by typical barbell apparatus. The embodiments herein permit a loaded barbell to be positioned in line with the axis of motion of the lift to be performed at both the beginning and end of the lift.

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.

The present invention provides a rehabilitation action guidance assistive device comprising a display device, a sensing device and a rehabilitation evaluation system. The display device displays an image for a user to watch and imitate. The sensing device comprises a sensing element, a storage element, a processing element, a data transmission element and a power supply element. The sensing element is used for sensing action state values of the rehabilitation carrier or the user; the storage element is used for storing the action state values; the processing element is used for performing a signal calculation; the data transmission element transmits the action state values to the rehabilitation evaluation system through a wireless communication method; and the power supply element provides an electric power with an operational function of the sensing device. The rehabilitation evaluation system indicates the difference in ratio between the user's action state values and reference action state values.
