Abstract: An electronic weapon impedes locomotion by a target by conducting a current through an electrode and through the target to produce contractions in skeletal muscles of the target that impede locomotion by the target. The weapon may include a deployment unit to deploy one or more electrodes away from the apparatus toward the target. The deployment unit may include an electrically fired primer, a first cavity, a second cavity, and a partition. The first cavity may include a pyrotechnic charge that produces a gas at an increasing pressure when ignited by the primer. The partition between the first cavity and the second cavity opens, in response to the pressure increasing to a threshold magnitude in the first cavity, to propel the electrode from the second cavity by a sudden release of the pressure.

Abstract: A method is performed by a deployment unit for an electronic weapon. The method includes describing the apparatus to a launch device of the weapon; and propelling the electrode in response to the launch device. The electrode conducts a current through a provided target to impede locomotion by the target.

Abstract: An apparatus records a use of force. The apparatus includes a weapon that initiates application of the force against a target, being a person or animal, to stop undesired behavior by the target. The apparatus further includes a processing circuit that provides, after an operation of the weapon, indicia of a prompt. The prompt elicits a spoken reply from an operator of the apparatus. The reply describes the use of force, and records indicia of the reply received from a provided input device. A method of operation of an electronic weapon includes applying a force wherein applying comprises passing a current through tissue of a target to produce contractions in skeletal muscles of the target to impede locomotion by the target; and recording a description of the application, the description in accordance with operator input.

Abstract: A weapon, according to various aspects of the present invention, includes a receiver, a trigger, and a cartridge store. The receiver receives a cartridge. The cartridge applies a deterrent force to the target. The trigger activates the cartridge. The cartridge store stores a plurality of provided cartridges. The cartridge store, then the trigger, and then the receiver are arranged in sequence proceeding linearly away from a user of the weapon.

Abstract: An apparatus for use in place of a round of percussion primed ammunition in a weapon includes a power supply and a switch. The switch is responsive to the mechanism in the weapon that fires the ammunition. Operation of the switch may enable the power supply to supply power to a replaceable cartridge. The cartridge may propel probes for delivering an incapacitating electrical charge from the power supply to the target. Another cartridge may include contacts to be applied without propellant to the target to stun the target. The apparatus may be inserted in the barrel of a weapon, for example, into the muzzle of a grenade launcher.

Abstract: A weapon that provides lethal force or non-lethal force at the discretion of the operator of the weapon includes a non-lethal implement attached by a support to the apparatus for lethal force. The support attaches to a picatinny rail and to a stop of the apparatus, such as a sight mounted on the barrel of the apparatus for lethal force.
