A substitute solid state device for safely initiating a sustainer motor is provided. The substitute device replaces a mechanism that is integral to a warhead. The substitute device interfaces to a telemetry package and is suitable for insertion into small housings. A specific embodiment is a substitute interface to a telemetry system incorporating a circuit for firing a sustainer motor of a small missile or rocket. The substitute interface replaces the interface and firing circuit associated with the warhead in a missile of 2.75-inch diameter, such as the STINGER missile.

[ I claim:] [1.]1. An action enabling apparatus, comprising:a device, having inputs and outputs, for timing activities and for activating signals based on the occurrence of a pre-determined sequence of events;a programmable logic device (PLD), incorporating timers and a first switch, and having inputs and outputs;a clock, having inputs and outputs, operably connected to said PLD;a first set of signal paths from said device to a first system, incorporating a sensor and having access to a power source, said first set of signal paths operably connected to said inputs of said PLD, said first set of signal paths comprising,a first signal path, operably connecting said clock and said PLD, for carrying a signal from said clock,a second signal path, operably connecting said PLD and said first system, for carrying a signal representative of event status as measured with said sensor,a third signal path incorporating a reset circuit, operably connecting said PLD and said power source associated with said first system, for carrying a reset signal; anda fourth signal path, operably connecting said PLD and said power source, for powering said PLD by said power source;a second set of signal paths from said first system to a second system, said second system incorporating an initiator;a third set of signal paths from said device to said initiator;a second switch,a thermal relay operably connected to said PLD through said second switch; anda third switch operably connecting said PLD to said second system, rein said action enabling apparatus initiates an action in said second system only upon a proper occurrence of said pre-determined sequence of events, and rein said PLD has the outputs of said PLD set to a pre-determined value at receipt of said reset signal, initiated upon power up of said first system by said power source.
