Abstract: The present invention relates to an electrified riot protection shield for keeping law enforcement officers safe while deterring rioters. The shield is designed as a multi-person shield and can be used by a plurality of security officers to shield their bodies, such that when one or more protestors touch a front surface of the shield, a non-lethal electric shock is administered to the protestor's body to deter the protestor or rioter. The shield can be held in front of the officers' bodies by grasping the insulated handles disposed on a rear surface of the device and an electric supply is provided to a metal plate from an integrated battery for providing the electric shock. A trigger is actuated to enable the electric supply to the metal plate and the trigger can be actuated when the metal plate is pushed or touched by a protestor.

Abstract: A device that causes a weapon to fire upon a target when the weapon is enabled by an operator, and when the weapon point of impact passes through a target or in a proximity thereto and when the target satisfies certain criteria as determined by one or more sensors/designations. This invention represents a significant paradigm shift. Some prior art (large scale) weapons automatically acquire/track/prioritize/target/fire upon targets without operator intervention (i.e. Phalanx). Most prior art weapons, especially but not limited to small arms, are manually aimed, and fire immediately upon an input (trigger pull, or equivalent) from the operator. The current invention is a novel approach which triggers the release of a round, multi-round burst, rocket, missile, or other projectile(s) when enabled by the operator, and when the target passes through the point of impact (or desired/computed proximity thereto), relieving the operator of the split second judgment in timing the release and/or cessation of such fire.
