Abstract
Apparatus having a plurality of signal channels, a plurality of stopwatch circuits and a plurality of time lapse displays interconnected so that the relative time lapses in a series of related occurrences can be displayed.
Claims8
A time sequence monitor for displaying the time elapses for a sequence of functional occurrences comprising:
- (a) a plurality of stopwatch circuits each having a start/stop connection and a display output connection.
- (b) a plurality of display means each connected to a respective one of said stopwatch circuits to display time intervals counted thereby;
- (c) a plurality of signal channels each of which comprises:
- (1) a signal sensor for detecting one of said occurrences;
- (2) pulse means connected to said sensor for providing an electrical pulse responsive to said sensor;
- (3) latch means connected to said pulse means for latching said pulse means responsive to a pulse output of said pulse means and inhibiting further pulses;
- and,
- (4) reset means connected to said latch means for resetting said latch to reenable said pulse means;
- (d) a common connection of the pulse means of one of said signal channels to the start/stop input connection of each of said stopwatch circuits;
- and
- (e) an individual connection from the pulse means of each of the remainder of said signal channels to one of the start/stop inputs of a respective one of said stopwatch circuits whereby all of said stopwatch circuits can be started or stopped by one common signal channel and said stopwatch circuit can be individually started or stopped by a respective signal channel.
