Various types of structures, along with associated systems, are disclosed herein and configured for responding to an energy wave for changing a state of a mechanism to which said structures are operatively coupled. In at least one embodiment, the structure provides a material selectively changeable upon exposure to the energy wave to cause at least a portion of the material to mechanically degrade from a first state to a second state. When the material is in the first state, the material forms a mechanical or electrical link with the mechanism such that a force or an electrical current can be transmitted through the structure. When the material is in the second state, degradation of at least the portion of the material disrupts the mechanical or electrical link and inhibits transmission of the force or electrical current through the structure.

A firing arrangement for an initiator (1) includes a capacitor (16), an arming arrangement (6, 11, 14) for charging the capacitor (16) on receipt of an arming instruction and a trigger device (13). When a trigger condition is achieved which indicates sufficient charge on the capacitor (16), a trigger signal is automatically generated by the trigger device (13) to trigger discharge of the capacitor (16) through the initiator (1) to activate the initiator (1). The trigger condition may be a predetermined time after receipt of the arming instruction.

An area denial system may be operationally placed with communication latency compensation. The area denial system may include a plurality of munitions, one or more sensor devices, and a command and control unit, networked together and having a command and control latency for communication between the command and control unit and the remainder of the area denial system. Latency compensation may include determining a first target position, determining a first predicted position area for the target using the command and control latency and the first target position, receiving an authorization to arm one or more of the munitions, determining a second target position, and determining that the second target position is outside a threshold distance from a first authorized munition of the one or more authorized munitions, and in response, de-authorizing the first authorized munition.

The present disclosure describes an electronic ignition circuit (EIC) for controlling at least one detonator. The EIC may include a protection circuit, an input circuit coupled to the protection circuit, a logic circuit electrically coupled to the input circuit, and an ignition circuit electrically coupled to the logic circuit. The protection circuit may include at least one of a fuse, a circuit breaker and an automatic switch. The logic circuit may include an answer back circuit, and a switching circuit adapted to switch to the next detonator or igniter. The ignition circuit may include a capacitor charging circuit, a capacitor discharge circuit to discharge a firing capacitor through a fuse head, and a shot detection circuit adapted to measure a voltage across the firing capacitor before discharging through the fuse head and to measure a voltage after discharging through the fuse head.

An electronic ignition circuit may include a logic circuit and an ignition circuit electrically coupled to the logic circuit. The logic circuit may include a microcontroller and a switching circuit configured to switch from a first detonator or igniter to a second detonator or igniter in response to a signal from the microcontroller. The ignition circuit may include a capacitor discharging circuit configured to discharge a firing capacitor through a fuse head. The capacitor discharging circuit may include an ignition switch configured to remain actively closed after the firing capacitor is discharged through the fuse head.

Life saving weapon and/or ammunition that comprises a remotely controlled firing mechanism to unlock and lock the striker remotely. The striker (S) is provided or modified with a hole or cavity (C44) which is to filled or vacated as per commands issued from remote command center, e.g., police control. The a miniature motor with gears and belt or alike mechanism may drive the motorized locking pin (ML) into the said hole/cavity, which immobilizes the striker and prevents the firing.
