    Abstract: An optical sensor has a sensor compensation to compensate for sensor degradation due to airborne contaminations in the operating environment. For example, in a thermal ink jet printing environment, the thermal ink jet operation produces misting or splashing of the thermal ink jet droplets, causing a gradual degradation of the sensor sensitivity due to a surface accumulation of the ink jet droplets. The optical sensor device includes an optical emitter emitting an optical signal according to an emitter input, an optical detector disposed to detect the optical signal and output a detector output having an output level according to the detected optical signal, a variable attenuator having an adjustable attenuation setting, and a controller adjusting the attenuation setting of the variable attenuator. During an adjustment operation, the controller determines the attenuation setting at which the output level of the detector output exceeds a predetermined value, and accordingly sets the variable attenuator to operate the detector output at an output level exceeding the predetermined value by a margin. Compensations for the optical emitter and the optical detector are disclosed, including the use of a variable pulse-width modulated signal.

    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 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.

    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.

    Abstract: A thermal or infrared imaging system that is particularly useful to enhance a vehicle operator's perception of surrounding scene features under vision-impaired conditions, e.g., rain, fog, smoke, and the like. Scene radiation is passed to an imaging sensor through a wavelength-selective attenuator that operates to pass radiation in a first wavelength range substantially without attenuation and to pass radiation in a second wavelength range with controllable attenuation. This permits maximum sensitivity to objects in the scene that radiate in the fist wavelength range and controllable sensitivity to objects that radiate in the second wavelength range, whereby the sensor may be prevented from becoming overloaded or saturated by radiation in the second wavelength range while continuing to produce useable image signals of objects in the scene that radiate in the first wavelength range.

    Abstract: In a luminaire, a diffusing unit diffuses the light, which has been emitted from a light source unit, according to light transmissibility. A position information obtaining unit obtains position information which at least indicates the position of a person. A luminance obtaining unit obtains the luminance of a luminous part at the position specified in the position information. A calculating unit calculates, according to the light transmissibility and the luminance of the luminous part, a luminance uniformity ratio which indicates the uniformity in the luminance distribution in the luminous part at the position specified in the position information. According to the luminance and the luminance uniformity ratio, a control unit varies the light transmissibility and varies the light output of the light source unit.
