  • Conductive energy weapon ammunition
    Patent number: 10101135
    Abstract: Ammunition for a conductive energy weapon. A receptacle includes a cavity accessible through each of a first opening in a first face of the receptacle, a second opening in the first face of the receptacle, a third opening in a second face of the receptacle and a fourth opening in a third face of the receptacle. A propellant unit is included within the cavity proximate the second opening and a projectile is included within the cavity proximate the second opening. A housing is coupled to at least the second face and the third face of the receptacle and is further configured to couple to the conductive energy weapon. The propellant unit releases a propellant into the cavity, in a direction substantially opposite the projectile's direction of flight, in response to a trigger pull of the conductive energy weapon, and the cavity directs the propellant in the projectile's direction of flight.
