    Abstract: An auto darkening eye protection device comprising a shutter assembly and a control circuit. The shutter assembly is adjustable between a light state and a dark state. The control circuit comprises a sensing circuit, a weld detect circuit, a positive voltage generator, and a negative voltage generator. The sensing circuit senses incident light and provides an output indicative of the incident light. The weld detect circuit receives the output of the sensing circuit, and enables a dark state drive signal to be delivered to the shutter assembly. The positive and negative voltage generators output the dark state drive signal to the shutter assembly to switch the shutter assembly from the light state to the dark state upon enablement by the weld detect circuit. The dark state drive signal includes a high voltage pulse followed by a stable AC waveform. The high voltage pulse is formed by a positive voltage signal and a negative voltage signal.

The circuit includes a sensor-responsive device and a controller. The sensor-responsive device produces an output that is a function of light sensed by glare and ambient light sensors. The controller connects one of the glare and ambient light sensors at a time with the sensor-responsive device to establish glare and ambient light levels and thereby the reflectance level of the reflective element. The mirror system may include a display operable to project light through the reflective element and may control the intensity of the display as a function of the glare light and ambient light.

    Abstract: Two mirrors are placed in such a manner as to line in a Z-axis direction in a beam irradiation head. These mirrors are located at a position beyond a normal scan range of the laser light in the Z-axis direction and within a limit range of scanning of the laser light, and the angles of inclination of mirrors are adjusted so as to reflect incident laser light toward a PD. In the case where a lens is driven in a Z-axis direction (a lateral scanning direction), driving current values Ia, Ib of an actuator at the times when reflected light from these two mirrors enters the PD at the maximum light quantity are detected. A driving current Imz required to position a lens for irradiation at a neutral position and a drive amount Azd of the lens for irradiation per a unit driving current are then determined based on the detected driving current Ia and Ib.

    Abstract: An auto darkening eye protection device including a shutter assembly, a light sensing circuit, a control circuit and a power supply source. The shutter assembly is adjustable to a plurality of shade levels. The phototransistor of the light sensing circuit senses light from a welding arc and provides an output of the light sensing circuit indicative of the shade level at which the shutter assembly should be operated. 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, drives the shutter assembly to one of said plurality of shade levels. 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.
