An electronic whistle system pertains to an electronically activated handheld whistle with a transmitter and receiver modules, for use at various sports games, is disclosed. The transmitter module is configured to send a serialized pulse signal to the receiver module for regulating the start and stop of the game clock. The transmitter module comprises an optical sensor on the opposite side of a vane, which occludes an optical sensor beam when the whistle is blown. A microcontroller sends a serialized pulse signal from the transmitter module to the receiver module. The receiver module intercepts the received signal on the detection of correct serial number, the receiver module will send a STOP pulse to the game clock via a cable. The electronic whistle system is designed to dramatically reduce the errors in the timing aspect of various games.

An apparatus and method for a hide-and-seek game, of which the apparatus includes a housing, a gameplay status indicator coupled to the housing, interface elements coupled to the housing and configured to receive input from a user or provide output to the user, and a processor configured to execute operations. The operations include initiating a timer in response to a first player selecting to play a hide-and-seek game and entering a first input using the interface elements, the first input indicating that the apparatus is hidden, receiving a second input from a second player prior to the completion of the timer, the second input indicating that the second player has located the apparatus that was hidden, and executing a predetermined number of challenges, in response to receiving the second input from the second player, using the gameplay status indicator and the interface elements.

A system for timing a basketball match includes a timing device linked to an optical ball detector and/or linked to at least one visual ball detector for detecting a ball in a basketball hoop. The optical ball detector includes an optical sensor positioned near or on the basketball hoop, and the visual detector includes at least one kinetic camera for detecting the motion of the ball in the basketball hoop with processing of the signal. A method for timing the basketball match, using the system, includes starting to count game time by activating the timing device, capturing, using the optical sensor and/or the kinetic camera, the passage of the basketball ball into a rim of the basketball hoop, and transmitting at least one signal detecting the passage of the ball into the basketball hoop to the timing device in order to stop game time.

A display method executed by a processor includes: acquiring an identification result relating to any one of a plurality of elements included in a series of exercise and a position of an athlete that performs the elements based on 3D sensing data that is acquired by sensing the series of exercise by the athlete of a sport scored by a judge and an element dictionary data in which characteristics of an element and a position of the sport scored by a judge are defined; identifying any one of an element and a position that is being displayed in a 3D model video based on the 3D sensing data corresponding to the series of exercise, based on the identification result; and identifying, for the any one of the element and the position being displayed, time information corresponding to a boundary with any one of a next element and a next position.

A game timer, suited in some embodiments as a chess clock, designed to calculate and display minimum average playing speed in moves per unit time over a sequence of one or more time controls based on input for number of moves in each time control, time allotted at the start of each time control, whether or not a delay applies to the moves of a particular time control, and time of the delay. In addition to these inputs, calculation of minimum average playing speed takes into consideration whether a delay comes before or after a move, whether or not a delay constitutes time available in the current time control, shortening of delays by players in the course of a game, and time remaining at the end of a time control. One embodiment estimates playing speed for sudden death over an entire game.
