  • Patent number: 5229981
    Abstract: A digital multi event timer that makes it simple to measure and record both time intervals and the actual times at which they begin. An electronic time base generates driving signals for seconds, minutes and hours. When a measurement set button is pressed, a counter begins at zero and counts up to the elapsed time count. Each time this button is pressed the beginning time and the interval are stored in non-volatile memory. The stored information can be retrieved from an ordered and index list. An independent index counter automatically stores data in the appropriate memory location. On retrieval, the user can manually scroll up or down the list.
