SYSTEM FOR REMOTELY STARTING AND STOPPING A TIME CLOCK IN AN ENVIRONMENT HAVING A PLURALITY OF DISTINCT ACTIVATION SIGNALS

摘要

A sports event time clock remote control system comprising a game clock and a plurality of sonic generators each adapted to be carried by one of a plurality of officials, in which each of said sonic generators provides a sonic signal when activated by the official carrying it, characterised in that said system comprises an analysis mechanism to analyze each of said sonic signals to determine which of said officials activated a sonic generator, in which said analysis mechanism converts said sonic signal to a sonic fingerprint signal including multiple harmonics of said sonic signal, in which said analysis mechanism further comprises a storage mechanism for storing prerecorded sonic fingerprint signals of each official, in which said analysis mechanism compares sonic fingerprint signals generated during a sports event with said prerecorded sonic fingerprint signals of each official, and in which said analysis mechanism generates a game clock actuating signal when a sonic fingerprint signal generated during said sports event matches one of said prerecorded sonic fingerprint signals.
