Abstract: An auto darkening eye protection device comprising a shutter assembly adjustable between a clear state and a dark state and a control circuit. The control circuit is provided with a microcontroller, a delivery circuit, a sensing circuit and a weld detect circuit. The microcontroller is switchable between a sleep mode and a wake-up mode. The delivery circuit outputs a dark state drive signal to the shutter assembly to switch the shutter assembly from the clear state to the dark state upon enablement of the delivery circuit. The sensing circuit senses the occurrence of a welding arc and provides an output indicative of the occurrence of the welding arc. The weld detect circuit receives the output of the sensing circuit. The weld detect circuit enables a dark state drive signal to be delivered to the shutter assembly by the delivery circuit, and a signal to be delivered to the microcontroller to switch the microcontroller from the sleep mode to the wake-up mode whereby the shutter assembly is switched to the dark state without the aid of the microcontroller. The microcontroller can compensate for a startup of the microcontroller which was not caused by user power-up by bypassing at least one of a plurality of initialization and calibration routines for the auto darkening eye protection device. The microcontroller also includes a protective casing disposed generally thereabout to substantially prevent electromagnetic fields from interfering with the operation of the microcontroller.

Abstract: An auto darkening eye protection device including a shutter assembly, a light sensing circuit, a control circuit and a power source. The shutter assembly is adjustable to a plurality of shade levels. The light sensing circuit senses light from a welding arc and providing an output indicative of the shade level at which the shutter assembly should be operated, the light sensing circuit includes a phototransistor operative to receive the light from the welding arc and produce a phototransistor output representative thereof. The phototransistor output from the phototransistor is used to form the output of the light sensing circuit. The phototransistor is configured for surface mount and has an external base connection connected to the base of the phototransistor. The control circuit is configured to receive the output from the light sensing circuit and provide a drive signal to the shutter assembly responsive to said output. The drive signal is operative to drive the shutter assembly to one of said plurality of shade levels. The power source is coupled to the light sensing circuit and control circuit for powering same. The present invention provides reduced power consumption, improved attenuation of low intensity light signals, a sharp rise time from the phototransistor in response to high intensity light, and allows implementation into a smaller sleeker eye protection device.
