Patent ID: 8111498

Claim:
A circuit that delivers an incapacitation current to a living target, the circuit comprising: a high voltage power supply; a charge-storing capacitor connected by a high voltage lead thereof to said high voltage power supply, said charge-storing capacitor storing a high voltage charge as supplied by said high voltage power supply; a switch; a step-up transformer including a primary coil and a secondary coil; a resonant capacitor connected in parallel with said charge-storing capacitor through said primary coil; and an output terminal connected in series to said high voltage lead of said charge-storing capacitor through said secondary coil, wherein said primary coil is connected in parallel with said charge-storing capacitor through said switch and said resonant capacitor, wherein, during delivery of said current, said output terminal is operatively attached to said living target; and wherein, when said switch is closed, any gap between said output terminal and said target undergoes electrical breakdown from energy stored in said charge-storing capacitor, and after said electrical breakdown, said incapacitation current is provided substantially from said charge stored in said charge-storing capacitor.
