Abstract
A non-lethal personal defense device that may be carried by a user includes a housing, a nozzle having a discharge orifice, a control valve coupled to the nozzle, a pressurized source containing a bio-active agent and coupled to the nozzle, a rangefinder for determining a range to a target, a trigger mechanism for activating firing of the device and a firing controller. The firing controller operates the control valve to discharge an aerosol plume of the bio-active agent through the nozzle in response to activation of the trigger mechanism and in response to the range determined by the rangefinder. The nozzle may include a spray orifice for discharging a pulsed aerosol spray plume at relatively long range and a mist orifice for discharging a pulsed mist aerosol plume at relatively short range. The pulse parameters are varied in response to the sensed range to the attacker. The personal defense device may optionally include a one or more cameras and a wireless communication link for transmitting status information, images and audio to a monitoring station.
