Abstract: An event detector for providing signals to general purpose digital computer hardware and/or software when excessive time passes prior to event occurrence. The detector includes storage means to record pluralities of sensitive events together with a time by which the event must be completed and clocking and comparator means to calculate target times and detect overruns.
