Abstract
Abstract A non-lethal self defense device which applies a disabling electric shock to personnel desired to be disabled employs fluid cartridges for containing an electrically conductive fluid. The fluid cartridges each have a reservoir for holding electrically conductive fluid and a nozzle through which is expelled the electrically conductive fluid during operation of the device. A compressed gas cartridge supplies the force required for expelling the electrically conductive fluid as a pair of continuous streams. The cartridges are supported by a frame whereby the nozzle portions of the two of the fluid cartridges are aimed in substantially the same direction. A displaceable linkage responsive to release of the compressed gas from the gas cartridge causes the electrically conductive fluid to be expelled. An electrification system, which may include an oscillator and coil arrangement powered by a standard battery, supplies electrical energy to the streams of electrically conductive fluid. Additives such as dyes, irritants, and odoriferous substances may be included with the electrically conductive fluid. Also, a lighting system can be used to identify the assailant and assist in aiming the device.
