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.

A sports event time clock control system utilizing remotely activated game clock controls in which the sonic fingerprints including multiple harmonic frequencies of each official's whistle blow is compared with prerecorded sonic fingerprints of the officials for activation of the game clock upon a match in sonic fingerprints and to identify and record the official who blew the whistle along with the strength of the whistle blow. Sonic fingerprints include the strongest harmonic plus selected strong overtone and undertone frequencies.

A computer system and computer-automated method for analyzing sports performance data from a game. A data set is provided that contains a log of a first time sequence of game data events which are classified into event types. A second time sequence is generated from the first time sequence by aggregating the events into game patterns, and a third time sequence is generated by aggregating the game patterns into game strategies. A multi-level time sequence event hierarchy is thus created. These multiple time sequence levels are rendered into a visualization in which the different types at each level are visually distinct from each other. The visualization reveals to a game expert player or team behavior in the data set which can be used for player and team improvement.
