  • Patent number: 5464965
    Abstract: A fast and accurate temperature controller for a device heated by current through a resistive element, such as various air data probes, wherein the resistance of the element varies with temperature. The temperature controller samples the temperature by selecting the resistance value of the resistive element. Analog calculations are performed based on the instantaneous applied voltage and current returned through the resistive element. Current through the resistive element is controlled by comparing the resistance of the element to a resistance value selected in accordance with the temperature characteristics of the element. Insensitivity to voltage and frequency variations is provided with a highly reliable and uncomplicated circuit having a small number of components.

  • Patent number: 4935166
    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.

  • Patent number: 4885575
    Abstract: Reprogrammable or softkeys are employed in a manner allowing significant flexibility in the display of information on a computer display means. Areas on the display corresponding to the softkeys are used to display the possible set of values of a parameter characterizing a function of a system or apparatus. Subsets of the set of values can also be displayed. Additionally, different variables can be displayed at the same location of the display at different times. The softkeys are further adapted to alter the state of the system or apparatus by affecting the parameter associated with each softkey when that softkey is activated in accordance with a prescribed pattern.

  • Patent number: 4866781
    Abstract: An optical system for determining if a target object is an object of a first kind, including means for illuminating the target object along an incident path with coherent light of a selected nature means, for retro-reflecting coherent light from an object of a first kind, means for detecting the nature of light reflected from at least a portion of the target object, means for comparing the nature of the detected light to the selected nature, and means for indicating that said target object is an object of a first kind if the nature of said detected light is the same as the selected nature. Alternative embodiments include encoding interrogating and retro-reflected light signals at both the interrogating station and target stations, and the use of a verification signal directed at the target object prior to illumination of the target object with an interrogating beam.

  • Patent number: 4848158
    Abstract: A single-axis rate sensor for determining angular speed .theta. in inertial space of an object rotating about the axis. The rate sensor includes a mass, a motor for rotating the mass about the axis at an angular speed .omega. relative to the object, and a microcomputer for determining a centrifugal force at a radius R from the axis due to the rotation of the mass about the axis at an angular speed .OMEGA. in inertial space, where .OMEGA. is the sum of .theta. and .omega.. Alternative embodiments provide a closed loop system where .OMEGA. is held constant, and a dual rotor arrangement which can be used to reduce a nonlinear factor in a relationship between .theta. and centrifugal force and/or to provide an in-operation self-checking feature.

  • Patent number: 4808837
    Abstract: An electrical generator in a water impermeable housing is driven by a water driven motor. The combination can be submersed with power delivered from the generator to a hydro-subsystem. The system is intrinsically safe in that all electronics are submerged during operation, thus any sparks emitted will not trigger secondary explosions in the surrounding environment. The supply is particularly useful in conjunction with submersible, remotely operated vehicles (ROVs), and diver assist power supply.
