Abstract: A low power consumption timing device using an oscillator and chained CMOS flip-flop devices providing all time-dependent functions, with an audible and/or visual alarm which signals after a predetermined elapsed time and continues until deliberately reset especially useful for repetitively timed events such as reminders for taking medication at fixed intervals. When reset the elapsed timer begins the next timed interval. A minor circuit revision, makes possible an automatic reset of the timer mechanism after each elapsed interval without disturbing the signal latch. This alternate method can produce constant period cycles without regard to other signal reset mechanisms.
