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.
