Abstract:
1. A timing device for timing two alternating sequences of events, comprising: (a) a pair of clock means for displaying the time remaining for each of said sequences respectively, (b) a pair of switches coupled to said clock means, each of which starts one of said clock means and simultaneously stops the other of said clock means, whereby the time remaining for each of said sequences is measured, (c) a first means for input and storage of a minimum average speed as the number of said events per unit time over each of said sequences respectively, (d) a second means for input and storage of a required number of said events in each of said sequences respectively, (e) a third means, connected to said first means and to said second means, for calculating an initial period of time for each of said clock means, based on said minimum average speed and said required number of said events, whereby it can be determined whether or not said minimum average speed is maintained over said sequences of said events.
