Classification: CPC F  G | IPC F  G

Claim 0:
1. A non-lethal handheld dazzling device comprising:
a housing having a forward-facing direction and a rear-facing direction;
a processor disposed in the housing;
a forward-facing range finder operatively connected to the processor, the forward-facing range finder being operative to detect a distance to a target in front of the forward-facing range finder and to transmit producing a distance to target signal to the processor, the distance to target signal representing the detected distance to the target, the processor being operative to program the laser drive circuit to generate a laser drive power;
a dazzling module coupled to the housing and operatively connected to the processor, the dazzling module comprising:
a first laser emitter oriented in the forward-facing direction and emitting a laser beam to produce a laser spot at a forward distance having a spot diameter that is proportional to the forward distance;
a laser drive circuit, the processor being operative to program the laser drive circuit to generate a programmed laser drive power based on the detected distance to the target, the programmed laser drive power having a first value when the detected distance is a first detected distance and a second value larger than the first value when the detected distance is a second detected distance larger than the first detected distance, the first and second values being operative to power the first laser emitter so that a 0.25 second exposure to the emitted laser spot at the first and second detected distances will not cause irreversible retinal damage; and
a laser trigger operatively coupled to the laser drive circuit and the processor whereby the laser drive circuit is activated by the processor in response to an activation of the laser trigger to produce the programmed laser drive power;
wherein the laser drive circuit powers first laser emitters.
