Abstract: A power saving welding helmet includes a helmet shell and a lens device. The helmet shell includes a mounting hole to contain the lens device. The lens device has an inner surface and an outer surface, and includes a magnetic sensor, a filter control unit, and a filter lens. The control logic module controls the filter lens according to magnetic signals generated by the magnetic sensor. The filter lens includes a first LCD panel and a second LCD panel respectively controlled by different control signals. Therefore, a refresh time of the first LCD panel and a refresh time of the second LCD panel do not synchronize. A welder does not feel the first LCD panel or the second LCD panel flashing, and the welding experiences this as consistent darkness.

Abstract: An imaging system includes an array of photodetectors and electronic circuitry associated with the photodetectors to read intensity values from the photodetectors. The electronic circuitry can include an integrator with an integrator capacitor having a nominal capacitance, wherein a gain of the electronic circuitry associated with a photodetector can depend at least in part on the actual capacitance of the integrator capacitor, the actual capacitance differing from the nominal capacitance. The imaging system can be configured to determine a gain factor that depends at least in part on the actual capacitance and/or a signal voltage input to the integrator. The imaging system can be configured to apply the gain factor based at least in part on the actual capacitance of the integrator capacitor calculated. The imaging system can be a thermal imaging system and may include an infrared camera core.

Abstract: Systems and methods for calibrating, operating, and setting the magnitude of the power of light provided by a laser diode in a conducted electrical weapon (“CEW”). The light of the laser diode assists in targeting by providing a visible indication of the projected point of impact of the tethered electrode of the CEW. The calibration process enables laser diode of a CEW to operate within regional guidelines of the maximum output power of light permitted by a laser. The method further permits the magnitude of the power of the light provided by a laser diode to be set and operated in changing environmental conditions in the field.

Abstract: The following steps are performed in connection with a photodiode circuit: a) resetting the photodiode circuit; b) determining when a photodiode voltage changes in response to illumination to reach a threshold; and c) updating a counter in response to the determination in step b). The steps a) to c) are repeated until an end of a measurement period is reached. The value of the counter at the end of the measurement period is then output to indicate an intensity of the illumination.

Abstract: A system with a machine and a lighting device. The machine includes an image capture device and a machine vision processing system configured to detect a characteristic of a subject in a space for an operation of the machine. The lighting device includes a first light source for generating light to illuminate the space, and a second light source for generating light of a particular wavelength to support detection of the characteristic of the subject via the machine vision processing system. The light of the particular wavelength is output at a sufficient intensity reasonably expected to produce a particular emission from the subject detectable via the image capture device different from an emission produced by exposure of the subject to the light for illumination of the space. The first and second light sources are integrated into the lighting device.

Abstract: An apparatus and method for determining and quantifying “sparkle”—the random noise that is generated when a pixelated image is viewed through a roughened surface of a transparent sample. The apparatus includes a pixelated source and an imaging system located in an optical path originating from the pixelated source, wherein a transparent sample may be placed in the optical path between the pixelated source and the optical system. The degree of sparkle is determined by obtaining an integrated image for the pixelated image; and calculating a standard deviation of the integrated pixel power. An objective level of sparkle can be defined by correlating the amount of sparkle provided by the apparatus with visual impressions.

Abstract: A method of determining the point source quality of a set of pixels associated with a detected energy signature is discussed that pre-records ideal test point source signatures at various sub-pixel locations and radiant intensities throughout the overall sensor field of view in a focal plane array, determines the sub-pixel location of an observed source, and compares the signature at a pixel of the observed source to the pre-recorded “ideal source” signatures at the determined sub-pixel location. to determine point source correlation.

Abstract: A position of a lens is detected by detecting, using a phototransistor, light that is emitted from a photodiode and that varies depending on lens position. A control unit divides a moving range of the lens into a plurality of areas, approximates a relationship between lens positions and current of the phototransistor for each of the areas, corrects a current of the phototransistor using the approximated relationship so as to obtain a corrected detection current having a linear relationship with respect to lens positions, and detects the position of the lens using the obtained corrected detection current.
