Abstract: An auto darkening eye protection device comprising a shutter assembly and a control circuit. The shutter assembly is adjustable between a clear state and a dark state. The control circuit comprises a sensing circuit, a weld detect circuit, and a delivery circuit. 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 delivery circuit outputs the dark state drive signal to the shutter assembly to switch the shutter assembly from the clear 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: An optical heterodyne detection system includes an attenuator for attenuating an input signal before the input signal is combined with a local oscillator signal. An optimal attenuation level for the input signal, which improves the signal to noise ratio of the heterodyne beat signal, is determined by obtaining a base measurement of an output signal in response to the local oscillator signal and in the absence of the input signal, obtaining sample measurements of the output signal in response to the input signal as a function of different attenuation levels, and determining the optimal attenuation level as a function of the base measurement and the sample measurements. A minimum attenuation level for the input signal, which protects receiver photodetectors from being saturated or damaged, is determined by setting an initial attenuation level and gradually reducing the attenuation level until the voltage limit of the photodetectors is reached.

Abstract: An imaging system for use in a vehicle headlamp control system includes an opening, an image sensor, a red lens blocking red complement light between the opening and the image sensor, and a red complement lens blocking red light between the opening and the image sensor. Each lens focuses light onto a different subwindow of the image sensor. The imaging system allows processing and control logic to detect the presence of headlamps on oncoming vehicles and tail lights on vehicles approached from the rear for the purpose of controlling headlamps. A light sampling lens may be used to redirect light rays from an arc spanning above the vehicle to in front of the vehicle into substantially horizontal rays. The light sampling lens is imaged by the image sensor to produce an indication of light intensity at various elevations. The processing and control logic uses the light intensity to determine whether headlamps should be turned on or off. A shutter may be used to protect elements of the imaging system from excessive light exposure.

Abstract: An imaging system for obtaining an image of a field-of-view where high levels of light from an extraneous source may be present at one area and low levels of light present at other areas in the field-of-view. The imaging system has a lens to focus an image of the field-of-view onto a surface of a photodetector and an optical limiter is located between the lens and the photodetector. The optical limiter limits transmission of the high levels of light at areas onto which those are focussed by the lens but remains transmissive to the low levels of light at other areas. The imaging system is particularly intended for use in laser warning receivers where sunlight may be focussed on the optical limiter and blocked at the particularly area on which it is focussed, the optical limiter remaining transmissive to laser beams, even if intense, at locations other than where the sunlight is focussed allowing laser beams to be detected by the photodetector.

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: A software controlled automatic shutter is described which minimizes ultraviolet irradiation damage to optical components from a high intensity spectrophotometric light source.

Abstract: A proximity switch module activated by an infrared reflective sensor that is triggered solely by IR light emitted by the module itself, turning on and off when a body is brought within activation distance, receiving the electrical network charge gradually, capable of being embedded into spaces intended for mechanical switches, allowing for positioning of three or more modules in line that operate independently. The switch module is based on an electronic board that includes an infrared reflective sensor, a capacitive power supply, a 100V to 250V optocoupler-activated thyristor, terminals blocks, a thermal safety fuse, capacitors, a status indicator light, a zero-crossing chip, a casing, a casing cover, and a piece that allows only IR light from the module to pass through.
