Abstract: In a projectile launch environment, a fuzing safety device independently generates its own voltage upon setback which then is then used to arm the projectile. The arming is done independently of any on board battery rise time, and setback scenarios are detected free of false impacts such as dropping or jostling. The fuzing safety device includes a piezoelectric sensor for detecting motion in the projectile.

Abstract: An improved system and method for generating high Voltage within an ESAD munition fuze is provided. Conventionally, high voltage transformer conversion circuits used within ESAD munition fuzes utilize a flyback, or step-up transformer. The use of a flyback, or step-up transformer reveal technical limitations when used for the application of increasing arm charge times, voltage conversion efficiency, and power conversion efficiency for ESAD munition fuze applications. Alternatively, the use of a high voltage inductor conversion circuit utilizing an inductor, in combination with a switching transistor allows for a new and improved low cost method for improving ESAD munition fuze applications with respect to generating high voltage from a low voltage source onto a detonator firing capacitor to trigger a Low Energy Explosive Foil Initiator (LEEFI) within an ESAD munition fuze.
