  • Patent number: 5854677
    Abstract: An RLG OPTICAL NOISE INJECTOR places a random signal on a PZT driving one mirror controlling the optical path length (OPL) of a ring laser gyro (RLG) and the negative of the signal on a PZT driving a second mirror controlling the OPL. The OPL is therefore maintained constant while injecting random noise into the phase of the counterpropagating beams to avoid dynamic lock-in. Static lock-in may also be avoided by superposing an oscillatory signal on the random signal fed to the first PZT and the negative of the oscillatory signal on the random signal fed to the second PZT.

  • Patent number: 5750203
    Abstract: An organically modified sol-gel method of preparing substantially crack-free aluminosilicates films is provided. Chelated aluminum alkoxide and polydimethylsiloxane are mixed in a 1:1 ratio by weight in a solvent and refluxed at approximately the boiling temperature of the solvent to produce a sol-gel liquid including polymerized aluminosilicates. The sol-gel liquid is cooled to room temperature. Additional solvent is added to the sol-gel liquid to reduce its viscosity. A substrate is coated with the reduced viscosity sol-gel liquid. The coating of sol-gel liquid on the substrate is dried to produce an organically modified aluminosilicates sol-gel film. The sol-gel film is heated, to enhance polymerization of the sol-gel film and to evaporate residual solvent, and then cooled.

  • Patent number: 5641329
    Abstract: The use of hydrocarbon fuels for cooling hypersonic aircraft and missile structures and engines is accomplished by passing fuel through cooling channels in the vehicle. A multicomponent hydrocarbon fuel having a pyrolyzing component which cracks in a supercritical temperature range (above 900.degree. F.) and thus absorbs heat is used in combination with a diluent fuel or fuel component which reduces the rate at which cracked hydrocarbons recombine in the cooling channels, thus causing coking which can clog cooling channels and also release heat to the structure to be cooled. The cracked fuel having absorbed heat and remaining in it's cracked state is in a condition to burn more quickly and energetically in the combustion chamber along with the hot diluent fuel, thus providing an efficient use of the heat absorbed in the cooling process and increasing the performance of the vehicle.

  • Patent number: 5638197
    Abstract: An optical O-plate compensation device, in accordance with the invention, uses an inorganic thin film which is grown by physical vapor deposition at oblique incidence. The resulting thin film exhibits a biaxial form birefringence and performs, in a liquid crystal display (LCD), in a similar manner to uniaxial films with its extraordinary axis oriented obliquely at about 45.degree. with respect to the surface of the film. The invention makes possible a significant improvement in the gray scale properties and contrast ratios of liquid crystal displays (LCDs) over a wide range of viewing angles.

  • Patent number: 5627986
    Abstract: An extended memory mapping and selecting scheme for a microprocessor structured with multiple internal address lines. The internal address lines are coupled to external memory devices via a dual port RAM which enables the addresses of the external memories to be mapped and translated into the internal address lines for access by the microprocessor. The memory addressing capability is effectively enhanced by allowing the limited number of internal address lines to address larger external memories having a greater number of address locations.

  • Patent number: 5619352
    Abstract: A twisted/splayed O-plate compensation device, in accordance with the invention, is comprised of an organic liquid crystal polymer thin film and possibly one or more other birefringent layers. The O-plate thin film is a birefringent medium with its optical symmetry axis, on average, oriented obliquely with the surface of the film. Within this constraint, the direction of the material's optical symmetry axis is allowed to vary continuously along the axis normal to the film surface. Such films may be fabricated by applying thin layers of chiral doped nematic or semectic liquid crystal monomer solutions in inert solvents to transparent substrates. The carrier solvents are then evaporated and the monomers polymerized by UV irradiation. Compensation devices may also be comprised of multiple layers of twisted/splayed O-plate material in conjunction with A-plates, C-plates, and simple O-plates. Fabrication techniques for twisted/splayed O-plates are described.

  • Patent number: 5615411
    Abstract: A composite signal recognizer, separator, and FM demodulator apparatus for processing received radio signals. The receiver utilizes N demodulators to process a received signal, where N is equal to or greater than the number of co-channel signals or perceived interference. Detailed in both cross-coupled and cascaded fashion, the receiver first tracks to a predominant (stronger) signal, and regeneratively improves track on other (weaker) signals by subtracting the predominant signal or the predominant noise portion from the input of further demodulation stages.
