US Patent 7237352 Projectile for an electrical discharge weapon

An electrical discharge weapon projectile for immobilizing a live target that includes a shock circuit having a low power consumption, a high power efficiency, and/or a low weight. In one embodiment, the projectile includes a high efficiency circuit that would reduce the weights of shock circuits while providing a more effective and safer power level, so that the circuits may be entirely contained within the projectile to eliminate the need for range limiting trailing wires.
