Abstract:
Disclosed is a timer of all solid state components and primarily formed from integrated circuits. The timer comprises a very low frequency oscillator coupled through a divider to an output circuit. In one embodiment, the timer is used to self-destruct a land mine after about twelve hours. In another, it produces an output from a magnetic core ring counter after about a year. Complementary MOSFET''s are used for the circuit components to minimize power consumption in both embodiments.
