A method for providing electrical energy to a self-destruct fuze for submunitions in a projectile, the method including: storing mechanical energy in an elastic element attached to a first movable mass at one end of the elastic element upon a firing acceleration of the projectile; engaging a second movable mass with the first movable mass such that movement of the second movable mass upon the acceleration moves the second movable mass which in turn moves the first movable mass; converting the stored mechanical energy to electrical energy upon the acceleration to vibrate the first movable mass and the elastic element to apply a cyclic force to a piezoelectric element attached to another end of the elastic element; and locking the second movable mass in a position where the second movable mass cannot interfere with vibration of the first movable mass upon the second movable mass being subjected to the acceleration.

A device for providing electrical energy in a submunition of a projectile upon an expulsion acceleration of the submunition from the projectile, the device including: at least one elastic element and a mass connected to the at least one elastic element such that a firing acceleration of the projectile deforms to store mechanical energy in the elastic element; and a mechanism for locking the elastic element in the deformed position and unlocking the elastic element due to the expulsion acceleration to vibrate the at least one elastic element and mass and apply a cyclic force to at least one piezoelectric element to convert the stored mechanical energy to electrical energy.

A weapon may comprise an explosive charge, an activatable detonation ignition means, an activatable deflagration ignition means, and an ignition device. The ignition device can activate, selectively, the detonation ignition means or the deflagration ignition means. The activated detonation ignition means can cause the explosive charge to detonate. The activated deflagration ignition means can cause the explosive charge to deflagrate. According to one method, the ignition device activates the detonation ignition means, which causes the explosive charge to detonate. If a predetermined event takes place without the explosive charge detonating, the ignition device activates the deflagration ignition means, which causes the explosive charge to deflagrate.

A system for deploying an electronic warfare package includes a projectile having an electronics payload for deployment in an environment. The electronics payload includes a processor and components that allow it to monitor an environment and initiate electronic warfare functions based on detecting a condition. The electronic payload also includes components that allow it to emit electronic signals for communication and/or disruption that can interfere with or otherwise affect local communications and computing devices.
