  • Patent number: 6410995
    Abstract: The invention provides a back up power supply for avionics equipment that can be installed in existing avionics equipment trays without having to rewire the aircraft. According to a preferred embodiment of the invention (described for illustrative purposes in the context of providing a power supply back up for a cockpit voice recorder (CVR)), the power supply/CVR combination is retrofit in an existing CVR rack. The power supply is modular; removable/replaceable; and is “independent” relative to the main aircraft power source and wiring. The modular power supply is designed to fit into a conventional CVR tray; and the modular power supply is designed to accept an existing CVR.

  • Patent number: 6222376
    Abstract: An improved capacitive moisture detector includes a ceramic substrate with a plurality of layers of interdigitated electrodes and a plurality of interleaved moisture sensitive dielectric layers. Alternate electrodes are electrically coupled to provide two electrical contacts and a circuit representing multiple capacitors connected in parallel. According to an exemplary embodiment, six layers are provided resulting in a structure presenting five parallel connected capacitors thereby providing a total capacitance of the detector which is ten times that of a prior art detector having the same footprint. According to a preferred embodiment of the invention, each dielectric layer is made relatively thin to effectively decrease the distance between the plates of each of the five capacitors. Since capacitance is inversely proportional to the distance between the dielectric layers, the thinness of the electrodes in the present invention also serves to increase capacitance.

  • Patent number: 5944970
    Abstract: A solid state electrochemical sensor includes a conductive base layer which supports a chemically sensitive membrane, a guard ring layer located below the base layer and insulated therefrom by a dielectric insulator ring layer. The two ring layers define a central hole through which access to the underside of the base layer is provided. The side wall of the hole is coated with a dielectric oxide layer and a metal conductor is laid on the oxide layer and is ohmically bonded to the base layer. A second dielectric oxide layer covers the metal conductor and a metallic inner guard layer covers the second dielectric oxide layer and is in ohmic contact with the guard ring layer. A CMOS buffer amplifier (voltage follower amplifier) is formed on the lower surface of the guard ring layer. The input to the buffer amplifier is coupled to the conductor in ohmic contact with the base layer and the output of the buffer amplifier is coupled to the guard ring.

  • Patent number: 5872595
    Abstract: The dynamic range of an image intensifier camera may be extended by using an automatic exposure control system which, in response to imager output (for example, the output of a charge coupled device (CCD) imager included in a solid state image intensifier camera), (a) generates a first control signal that controls the gain of the I.sup.2 Tube itself; (b) generates a second control signal for selectively gating the I.sup.2 Tube on or off; and (c) generates a third control signal for controlling a light attenuator that, according to a preferred embodiment of the invention, is included in the camera. The automatic exposure control system contemplated by the invention has a control range in excess of 10.sup.10 .times.; takes a measurement of the exposure from an imager (again, for example, a CCD sensor) for comparison to a desired setpoint; the measurement used may be a peak, an average or some weighted function and the automatic exposure control logic then adjusts, in order, the I.sup.2 Tube gain, the I.sup.

  • Patent number: 5794660
    Abstract: A non-refillable valve for a pressurized container which includes a unidirectional stepped valve housing within which a freestanding blocking element is housed. The blocking element is preferably a reversible, symmetrical check that integrally includes stop means for preventing the return of said blocking element to an initial location after it has been moved to a final location that activates the one way characteristic feature of a non-refillable valve (where activation is designed to take place after initially charging of the container). Further aspects of the invention relate to blocking elements (checks) per se which are suitable for use in non-refillable valves.
