Abstract
An improved power supply (10) for an electrical circuit (12) mounted on a projectile. The inventive power supply (10) includes a mechanism (14) on the projectile for generating electrical energy on the acceleration thereof. The energy is stored and released to a load on the deceleration of the projectile. In a particular implementation, the energy producing mechanism (14) is a piezo-electric transducer. Storage of electrical energy in the transducer is facilitated by the connection of a diode (16) across the output terminals thereof. An acceleration switch (18) is provided which is mounted on the projectile to be open on acceleration and closed on deceleration thereof. The switch (18) thereby releases a predetermined amount of stored energy to the load (12) only on the impact of the projectile with an object.
