An apparatus and method for measuring a swimmer's speed and conveying the speed to the swimmer in real time includes a plurality of ultrasonic beacons each having a transducer configured to emit ultrasonic signals in a pool or other body of water within which the swimmer is swimming. A wearable, waterproof, ultrasonic receiver worn by the swimmer, receives the ultrasonic signals and generates corresponding signal data. The receiver's microcontroller captures and uses the signal data to calculate the swimmer's position and speed in real time, and conveys this information to a wearable, waterproof, user interface device worn by the swimmer, the user interface device including a near-eye display disposed on the swimmer's goggles.

A muscle training method and system for providing visual feedback by using ultrasonic imaging. The method comprises: determining a training object and target training data; acquiring ultrasonic images of a target muscle of the training object during contraction process, and respectively selecting regions of interest from ultrasonic image frames; extracting muscle characteristic parameters of the target muscle from the selected regions of interest; according to the muscle characteristic parameters, obtaining a training index value ; converting the training index value into visual feedback signals displayed in real time, and synchronously displaying the visual feedback signal and the ultrasonic images; comparing the training index value with the target training data, and according to an instantaneous comparison result between the training index value and the target training data, generating prompt information corresponding to the target muscle so as to guide the training object in real time to perform target muscle training

A method of operating an electronic basketball scoreboard apparatus is disclosed. The method includes receiving a game parameter; operating a basketball game based upon the received game parameter; receiving a first indication of a ball passing through a first basketball hoop; receiving a second indication of a ball passing through a second basketball hoop; determining a first score of the basketball game based on the first indication from the first score sensor; determining a second score of the basketball game based on the second indication from the second score sensor; recording video of the basketball game; transmitting the recorded video; and transmitting the first score and the second score.

Electronic tracking systems are disclosed for assisting users with locating objects in a sporting environment. One such system includes a ball tracking component that tracks a game ball while moving in the sporting environment, and a heads up display that is worn by the user. This heads up display has an electronic display screen with a transparent display area that dynamically displays images within the user's field of view. A processor, which communicates with the ball tracking component and heads up display, is programmed to detect movement of the game ball, and responsively determine launch characteristics and/or flight characteristics of the moving game ball. The heads up display displays the launch/flight characteristics contemporaneous with an object indication adjacent to or superimposed over the moving game ball as the game ball is visible through the transparent display area of the display screen within the user's field of view.

A training apparatus is disclosed that comprises an obstacle member defining a pass-under area for a sports player to pass a sport-projectile through when in use. The training apparatus comprises a first sensor that is configured to detect the sport-projectile passing through the pass-under area, and a controller that is configured to determine a pass-through direction of the sport-projectile that passes through the pass-under area based on data received from the first sensor. The training apparatus also comprises a lighting fixture indicating an instructed pass-through direction for the sports player to pass the sport-projectile through the pass-under area. A system for training a sports player is described that comprises a plurality of training apparatuses that are remotely configurable to define a training drill for a sports player and to collect training data from execution of the training drill. A method for training a sports player is also disclosed.

A ball picking robot and a ball unloading method using the same. The ball picking robot includes a chassis, an L-shaped hanging lug, a ball storage frame, an electric push rod disposed on the chassis, a baffle disposed on the chassis, a bracket disposed on the chassis and a drive motor for driving the electric push rod to move. A movable end of the electric push rod is connected with one end of the L-shaped hanging lug, the other end of the L-shaped hanging lug is connected with a side of the ball storage frame, and a camera is disposed on the bracket.

A golf instruction method, apparatus and analytics platform for determining the state of a putted golf ball relative to a target using information about the golf ball and external variables and remotely displaying the same comprising a base unit, a mobile device or terminal, and an associated computer program including an analytics engine for analyzing a user's performance. The computer program determines whether and how a putted golf ball has missed said target and then stores, aggregates and displays that information for a user. The analytics engine is operable to aggregate data, analyze data and then correlate a user's actual skill proficiency to ball performance.

Detectors and related systems and methods for automatically detecting made and missed basketball shots using ultrasonics are provided. A launcher is connected to a structural subassembly and passes basketballs to locations about a basketball playing area having a basketball goal. A detector having at least one ultrasonic sensor is selectively positioned below and adjacent to a rim of the basketball goal and transmits bursts of ultrasonic signals. A processor monitors for reflections of the transmitted bursts occurring within a specified time period after transmission excluding an initial time period and time after the specified time period, and records a made shot where reflections of the transmitted bursts are detected within the specified time period. An accelerometer may optionally be included for determining if the made shot was a swish.

A method and system for movement guidance, an electronic device, and a server are disclosed. The method includes: receiving a first ultrasound signal from a first ultrasound emission device via a first sound reception device and receiving a background sound signal via the first sound reception device synchronously, wherein the first ultrasound emission device is worn on a body of a first user; generating a multimedia file according to the first ultrasound signal and the background sound signal; detecting a first signal feature of the first ultrasound signal, wherein the first signal feature reflects a first physical movement performed by the first user at a first time point; and generating a first guidance message according to the first signal feature, wherein the first guidance message is used for guiding a second user to perform the first physical movement at a second time point.
