Abstract
A rate calculator for calculating, displaying and continuously updating the rate of occurrence of events. Manually entered signals indicative of the occurrence of an observed event trigger a resettable counter for counting the number of events. A clock is activated by the first entry signal for measuring the time duration from the first entry and a processor responds to the counter and the clock for cumulatively calculating the rate of occurrence of each event from the second event on. A display of the calculated rate is provided for visual perception.
