Abstract
Automated Interval Timing Method Devices and System for automatically timing a plurality of moving entities over a course with predetermined finish line are delineated. Each moving entity wears, carries or has mounted on it a timing unit which is actuated by an acoustic starting signal. A device is located at the finish line so as to create an acoustic field that is narrow in the direction of travel of the moving entities. As each moving entity crosses the finish line, the timing unit detects the finish line acoustic field and records and displays the elapsed time from the acoustic starting signal to the crossing of the finish line. More particularly the timing system comprises wearable or mountable stopwatches, and an array of narrow-beam acoustic transmitters located at the finish line. Each participant or vehicle in a race wears or carries a stopwatch. Each stopwatch is started by the sound of a starting pistol or an electronically generated starting tone or other distinctive acoustic starting signal. Split times and finish times are recorded by the stopwatch when it recognizes the finish line acoustic signal.

11. The process of automated interval timing for automatically measuring event intervals of a plurality of moving entities comprising the steps of:
-
a) donning a wearable timing device on each said moving entity; b) arming said timer in state ready to receive a START signal; c) starting each said timer upon receipt of said START signal; d) recording the elapsed time of an acoustic signal present at the finish line; and e) calculating, displaying and communicating time intervals based on recorded finish line crossing times. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
