According to one example, a training device includes a first set of time of flight sensors (ToF) positioned to face in a first direction, a plurality of addressable red, green, blue light emitting diodes (RGB LEDs) positioned to face in the first direction, and a second set of ToF sensors positioned to face in a second direction that is perpendicular to the first direction. The training device includes and/or is in communication with one or more processors that can determine a training program for a user that includes visual signals that represent a plurality of actions for performance by the user. Also, for each of the plurality of actions, the training device can cause a first set of the plurality of addressable RGB LEDs to provide a visual indication of the corresponding action for performance by the user, and detect whether the user performed the corresponding action.

A sensing system and method determines whether a slow pitch softball has been delivered in a strike zone. The system includes: a dual, mirror image slow-pitch software home plate; the home plate having an upper surface and a lower surface; the lower surface configured for attachment to ground; the upper surface comprising a pressure or impact sensing array covering at least edges of the upper surface of the home plate; the sensing array having a battery source for powering the system; the sensing array issuing an electrical signal when sensing pressure or impact; and the electrical signal connected to an audio or visual output device that indicates receiving of the electrical signal by a visual or audio emission.

A basketball system comprising a court system having shot locations defined by shot location lines on the play surface and the shot areas defined by shot area lines on the play surface, and a goal system comprising a respective backboard suspended above the play surface at each opposing farthest end of the play surface, an instrumentation system comprises sensors to detect activities within the boundary line of the court system, and a respective penalty box for each team in which players, coaches, and referees can serve a penalty assessed for an infraction.

Swimming goggles have a left-eye covering and a right-eye covering, each having a corresponding transparent window that defines a field of view and each further having a seal extending between the transparent window and the swimmer's face and formed to exclude water. A near-eye display is in signal communication with an image processor and forms a virtual image in the left- or right-eye field of view.

A method of creating a scalable dynamic jointed skeleton (DJS) model for enhancing psychomotor leaning using augmented cognition methods realized by an artificial intelligence (AI) engine or image processor. The method involves extracting a DJS model from either live motion images of video files of an athlete, teacher, or expert to create a scalable reference model for using in training, whereby the AI engine extracts physical attributes of the subject including arm length, length, torso length as well as capturing successive movements of a motor skill such as swinging a gold club including position, stance, club position, swing velocity and acceleration, twisting, and more.

A system that includes an electronic baton device with motion and capacitive sensors. The system includes a processor and non-tangible computer readable media having stored programming instructions thereon that, when executed, cause the processor to receive sensor data from the motion and capacitive sensors, and determine an exchange zone to exchange the baton device between an incoming runner and an outgoing runner of a relay, based on the sensor data. The processor determines relay race metrics for each athlete of the relay team, baton metrics associated with each athlete, a usage efficiency in the exchange zone, and a baton transition metrics. The processor selectively displays on a display device the relay race metrics for each athlete, the determined baton metrics, the determined usage efficiency in the exchange zone, and the determined baton transition metrics in one or more selected graphical user interfaces.

A method for controlling a treadmill using a workout video comprising receiving a workout video at a treadmill comprising a display, an endless belt, one or more actuators configured to control a speed and incline of the endless belt, and one or more processors. The method may also include displaying, by the one or more processors, the workout video on the display, wherein the workout video includes audio of a song, text of lyrics of the song, and an indication of progress through the lyrics. The method may also include controlling, by the one or more processors, actuators of the treadmill according to control signals associated with the workout video.

The article is a tubular construct of knitted or woven yarns irreversibly attached thereto a play caller. The play caller comprises a polymeric base sheet having a length and a width, the polymeric base sheet having a first major surface and a second major surface, and a plurality of second polymeric sheets having a length and a width less than or equal to the length and width of the polymeric base sheet. The plurality of second polymeric sheets are separated from each other by a distance and coupled to the second major surface of the polymeric base sheet along at least one of their widths or lengths defining a plurality of pockets, the pockets having openings and at least a portion of the play caller is irreversibly coupled to the tubular construct. Methods of constructing the article are also described.

A system for detecting a ball or strike in baseball.
