Abstract:
Laser safety systems, devices, and methods for use in laser projectors are described. A laser projector includes any number of laser diodes that each emit laser light, a laser diode power source, a current sensor to detect a magnitude of the electric current output by the power source, a photodetector to detect a power/intensity of the laser light, a beam splitter to direct a first portion of the light towards the photodetector and a second portion of the light towards an output on the projector, and first and second laser safety circuits responsive to signals from the photodetector and the current sensor, respectively. The laser safety circuits selectively electrically couples/uncouples the laser diodes from the power source depending on signals from the photodetector and/or the current sensor. Particular applications of the laser safety systems, devices, and methods in a wearable heads-up display are described.

Claim (Index 6):
The WHUD of  claim 1  wherein the second laser safety circuit further includes a second latch that is communicatively coupled to the current sensor and to the second switch, and wherein:\n a state of the second latch is responsive to signals from the current sensor and the second switch is responsive to the state of the second latch; \n the state of the second latch changes from a first state to a second state in response to the signal from the current sensor indicative that the electric current output by the power source exceeds the second threshold; and \n the second switch interrupts the supply of power to the at least one laser diode from the power source in response to the state of the first latch changing from the first state to the second state.
