ABSTRACT:
A device for producing an electrical output within a larger apparatus which generates the electrical output by use of energy already available within the apparatus. The device is particularly adaptable for use within an apparatus which incorporates an explosive charge which detonates during the operation of the apparatus. The device employs a piezoelectric cell which is positioned within the apparatus at a location such that when a force or shock wave is generated within the apparatus, that force is at least partially applied to the piezoelectric cell. Thus, an electrical voltage is generated by the piezoelectric cell. The device also includes a wire or other device for transporting the electrical energy to an appropriate location for use. The device may be placed within a flare of the type propelled by a rocket motor and also having an explosive charge for separating the rocket motor from the remainder of the flare. The piezoelectric cell is in turn placed in electrical communication with an igniter for the illuminate of the flare. For some purposes the piezoelectric cell may be shielded from the explosive or other force producing component by means of a burst diaphragm.
