  • Interferometric signal analysis with modulation switching
    Patent number: 5137357
    Abstract: In a fiber optic rotation sensor, two phase modulators are symmetrically offset with respect to the center of an optical fiber loop and alternately excited by a waveform whose frequency alters the differential phase between counter-propagating light waves in the loop to maintain a fixed intensity signal at a detector upon loop rotation. The difference between the waveform frequencies is proportional to the speed of sensor rotation while the mean value of the waveform frequencies equals the frequency value in the absence of sensor rotation. In the alternative, a single modulator is excited by a waveform whose polarity is reversed at intervals of time.

  • Inertial navigation sensor integrated obstacle detection system
    Patent number: 5128874
    Abstract: A system that incorporates inertial sensor information into optical flow computations to detect obstacles and to provide alternative navigational paths free from obstacles. The system is a maximally passive obstacle detection system that makes selective use of an active sensor. The active detection typically utilizes a laser. Passive sensor suite includes binocular stereo, motion stereo and variable fields-of-view. Optical flow computations involve extraction, derotation and matching of interest points from sequential frames of imagery, for range interpolation of the sensed scene, which in turn provides obstacle information for purposes of safe navigation.

  • Scanning laser helmet mounted sight
    Patent number: 5128794
    Abstract: A scanning laser helmet mounted sight that determines helmet or sight position from externally mounted light sources and detectors. No electronics, including light sources and detectors, are on the helmet. Also, no electrical cables or mechanical linkage is connected to the helmet. The helmet has passive reflectors for reflecting a scanning light beam from a laser source. The return times and directions of the returning light beam relative to a return of a light beam from a reference point, processed by the off-helmet electronics, result in a position indication of the helmet.

  • Liquid crystal display with sub-pixels
    Patent number: 5126865
    Abstract: A half-tone pixel having subpixels and control capacitor constituting a 100 percent optically active pixel. The subpixel design results in no reductions in the maximum pixel aperture ratio, brightness or contrast, as a pixel with no subpixels would have. Various subpixel layouts including differing numbers of subpixels and subpixel-turn-on sequences may be implemented and still result in the entire pixel being optically active.

  • Narrow band selective absorption filter
    Patent number: 5102213
    Abstract: A solid state form of a dye-solution absorption filter is disclosed. Physical vapor depositable (i.e., evaporable) dyes are codeposited with a polyester matrix in a vacuum system to randomly disperse dye molecules in a solid dilutant. The dyes are selected to absorb at the wavelengths of interest. Dilution in a transparent matrix affords narrow band absorption and good out of band transmittance. Multilayer configurations allow absorption of a plurality of wavelengths. The filter coating conforms to curved and sharply contoured surfaces and layers only 10 microns thick afford very high absorptance.

  • Electrically passive fiber optic position sensor
    Patent number: 5042905
    Abstract: An electrically passive fiber optic position sensor having a course measurement indicator and a fine measurement indicator combined to determine the overall position, whether linear or angular, of an object measured. The coarse measurement sensor depends on bending loss of optic fiber in one embodiment and on the Faraday effect in another embodiment. The fine measurement indicator depends on the Faraday effect in both embodiments. The invention avoids the problems of contaminated optics as the light need not leave the optic fiber.

  • Flicker-free liquid crystal display driver system
    Patent number: 5041823
    Abstract: A flicker-free liquid crystal display driver system driving two groups of pixels with alternating polarities. The spatial differentiation of the two groups, which may be accomplished in terms of even and odd rows or columns, is small so as to diminish detection by a human eye of the flicker in the display. The driver system incorporates a level shifter, switches, drivers, a driver switch control, a holding means and a storage means. Input signals to the system include that of intensity data, a clock and frames. The configuration of the driver system may be of a single-edge or redundant drive. The system may be digital or analog.

  • Knowledge and model based adaptive signal processor
    Patent number: 5018215
    Abstract: A knowledge and model based adaptive signal processor for ensuring optimum performance in automated object recognition (AOR) systems. The invention does not require ground-truth information but uses predictive performance models for parameter adaption and updates for the AOR. The performance models are representations of continuous surfaces that interpolate and extrapolate for data and scenarios not previously tested. The present invention increases probability of detection and decreases false detection alarm rates of AOR systems.
