ABSTRACT:
An athletic jump duration timing apparatus is designed to measure the time from when an individual initiates a jump until he or she lands from the jump or stride. The apparatus will measure and display the elapsed time of the individual's flight or "hang time". A timing device is positioned in a housing. The timing device is activated by a sensor positioned under a weight bearing surface. A signal is sent to a controller which simultaneously activates two previously zeroed timers. These timers or counters begin counting the impulses from a clock generator. When the sensor senses a weight, the signal is given to the controller to cease the flow of impulses, which freezes the two counters. The event counter is cleared back to zero and the hold counter displays the hang time for the count value. Subsequent jumps are measured and the hold counter displays the jump with the longest hang time by comparing each jump against the event counter.
