There is provided a system for detecting an object crossing a plane at high resolution from long range, the system including a first transmitter projecting a light plane using a light comprising a light plane wavelength, the light plane defining a boundary, wherein the light plane wavelength is not visible to the human eye, a first receiver for detecting a reflection of light when an object crosses the light plane defining the boundary, the receiver configured to detect light in a range of the electromagnetic spectrum including the light plane wavelength, wherein the receiver includes an image sensor comprising a plurality of sensor pixels, and an image processing computer configured to receive an input from the receiver including a recorded frame captured by the receiver, wherein the image processing computer processes the recorded frame for review to identify a frame showing an object crossing the boundary.

An evaluation method for a computer to execute a process includes, acquiring a plurality of pieces of skeleton information in time series based on position information of joints of an object that executes a plurality of motions; specifying a transition period between a first motion and a second motion that follows the first motion, which are included in the plurality of motions based on the plurality of pieces of skeleton information; determining whether the transition period is related to a certain combination of motions by inputting skeleton information among the plurality of pieces of skeleton information that corresponds to the transition period into an evaluation model trained to evaluate a transition period between motions based on a plurality of pieces of skeleton information in time series; and outputting an evaluation result of the transition period by the evaluation model.

A conductive material of a plurality of separate conductive materials are coupled to a first participant, the conductive material configured to move when the first participant delivers an impact to a second participant. An impedance-based impact sensing mechanism including an impedance changing mechanism that changes impedance as the conductive material is moved towards and away from the impedance changing mechanism as the first participant delivers the impact. An impedance-based impact measuring scoring system determines that the impact occurred based on a change in impedance in the impedance changing mechanism.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

Disclosed is system and method for measuring the tension of a tennis net, and, alternatively or in addition, for determining if a service let occurs via the measuring of the net tension. The disclosed embodiments measure a force exerted on the center-strap or the singles stick by the net. In these embodiments, the measured force provides an accurate reflection of the tension of the net.

A game set having a flying disc, a goal mount, a target loop configured to attach to the goal mount, the target loop having a loop surface with a solid outer portion that surrounds an open middle portion, the open middle portion having at least one distinct opening, each distinct opening defining a scoring portal, and a score controller having at least one score sensor configured to detect the passage of the flying disk through each scoring portal, a vibration sensor configured to detect the target loop being impacted and wherein the score controller is configured to emit an alert when a sensor is triggered. The score controller may be further comprised of a viewing camera, microphone, game clock, scoreboard, distance verification device, loudspeaker, score buzzer, score indicator light, battery, and wireless transmitter. The score controller may communicate with a game application on a device, enabling “physical virtual” play.

A ball game apparatus in which movements of a coded ball (20) are detected by detector units (100, 206) and an automatic indication of a player's score is given, where data relating to the ball (20) are stored in a database connected to the detector units (100, 206), the data including the code of a ball (20) and a code relating to a player to whom the ball (20) has been allocated, the ball (20) being configured to temporarily store, and to intermittently transfer to the detector units (100, 206) and thence to the database, data relating to the ball's movements. A rechargeable battery (40) is contained within the ball (20), and is arranged to be charged by a battery charging system. Features of the game may be controlled by means of a player's mobile telephone.

An athletic training system (200) has a data recording system (202) and a data engine (204). The data recording system (202) is configured to record an athletic competition event. The event may have a first team of players competing against a second team of players. The data engine (204) is configured to receive data associated with the recorded athletic competition event. The data engine (204) processes the data and displays the data as a replay of the event in animated form.

Methods and apparatus relating to predicting outcome in a sporting environment are described. The methods and apparatus are used to relate trajectory performance of an object to body motions and body orientation associated with a generating the trajectory of the object. When equipment is utilized to generate the trajectory of an object, than the effects of equipment motions and equipment orientation can be also related to trajectory performance. The method and apparatus can be used to predict body motions and body orientations that increase the likelihood of achieving a desired outcome including specifying optimum motions and orientations for a particular individual. The method and apparatus may be used in training, coaching and broadcasting environments.

A golf analysis assistance apparatus includes an input/output unit, a golf course data storage unit, a player data storage unit, a target score acquisition unit configured to acquire a target score throughout a course, the target score being set by a player, and a control unit. The control unit is configured to obtain an optimal solution at each hole that enables achievement of the target score throughout the course, the target score being set by the player, based on golf course data and player data.
