  • Patent number: 5509517
    Abstract: The flying wedge clutch assembly is a speed actuated coupling device that provides low speed axial load and torque transmission and disengages for increased shaft motion at higher speeds. The flying wedge clutch assembly is a compact and lightweight design, roughly equivalent to a conventional ball bearing assembly in a typical turbopump application. Advantageously, the flying wedge clutch assembly can be used in high speed rotating machines with radial hydrostatic bearings eliminating the speed and life limitations normally attributed to rolling element bearings.

  • Patent number: 5506066
    Abstract: An ultra-passive, variable pressure, regenerative fuel cell system in accordance with the invention utilizes a single gaseous hydrogen storage tank that encloses a plurality of smaller gaseous oxygen storage tubes. This design effectively eliminates the need for active pumping elements to protect the fuel cell's anode surface. A single heating/cooling coil, inside the gaseous hydrogen storage tank, is used to prevent: (a) icing inside the storage tanks due to isentropic expansion during electrical power generation, or (b) overheating of gases due to isentropic compression during electrical recharging operations. Advantageously, the invention also reduces the overall weight and mechanical complexity of the fuel cell system, thereby improving system reliability.

  • Patent number: 5495408
    Abstract: A feedback control loop having a variable attenuator controlled by oscillation detector means and overshoot detector means to better track the input signal. The oscillation detector means utilizes an estimated signal value compared to a subsequent measured value with the absolute difference of the two compared to predetermined threshold values. Should the calculated difference exceed predetermined threshold values, the variable attenuator value is adjusted and the process repeated after a brief disabling period to allow settling.In addition to the oscillation detector, an overshoot detector means may also be used alone or in combination with oscillator detector means to control the variable attenuator setting.

  • Patent number: 5491725
    Abstract: A tracking filter has a tunable filter responsive to an input signal for producing a filtered output signal, a Hilbert transformer for producing an in-phase reference signal and a quadrature-phase reference signal from the filtered output signal, and a discriminator responsive to the input signal and the in-phase and quadrature-phase reference signals for producing a passband center frequency control signal and a passband width control signal for controlling the passband center frequency and the passband width of the tunable filter. The frequency discriminator performs complex demodulation of the input signal with the in-phase reference signals to produce respective in-phase and quadrature-phase baseband signals which are low-pass filtered. The quadrature-phase baseband signal is divided by the in-phase baseband signal. The quotient is integrated to produce the passband center frequency control signal.

  • Patent number: 5488378
    Abstract: A method for using a value of range rate observed by a receiver, such as a GPS receiver, at a particular location, along with other satellite information, to determine the coordinates of points on the surface of the earth from which this value of range rate would be observed. These coordinates are given in an earth-centered, earth-fixed (ECEF) coordinate system, and they form a locus of points of equal range rate. The coordinates of these points provide estimates of the location of the GPS receiver.

  • Patent number: 5487015
    Abstract: A drive circuit provides approximately zero phase shift across the terminals of a resonator, and provides a constant excitation of the resonator, while cancelling variation due to the shunt capacitance. For complex demodulation of an angular rate signal from a vibrating quartz angular rate sensor, the drive circuit also provides an in-phase reference signal and a quadrature-phase reference signal. Preferably, the drive circuit includes an adjustable phase shifter connected in a feedback loop including the resonator for adjusting a phase shift of a periodic signal circulating in the feedback loop, and the adjustable phase shifter includes a Hilbert transformer for producing an in-phase signal and a quadrature-phase signal, and a combiner circuit connected to the Hilbert transformer for combining a selected amount of the quadrature signal with the in-phase signal to produce a result shifted by a selected amount of phase.

  • Patent number: 5486795
    Abstract: The LOW POWER CRYSTAL OSCILLATOR shown here reduces power consumption of a Pierce oscillator which has an inverter preferably made of an NFET N0 and a PFET P0 in series. A load, preferably an NFET N1 with its gate wired to its source, is placed in parallel with a switch, preferably a PFET P1, between P0 and Vcc. A clamp, preferably a PFET P2 with its gate wired to its source, is placed in parallel with a switch, preferably an NFET N2, between N0 and ground. The switches are enabled during power-up, thereby providing quick turn-on of the oscillator. They are then disabled, thereby reducing the voltage across the crystal XTAL and consequently reducing the power consumed.

  • Patent number: 5485590
    Abstract: A module interfaces a programmable controller to several serial communication networks over which data may be exchanged according to different protocols. A module has a central controller and a separate port circuit for each of the networks. Each port circuit includes a microprocessor and a shared memory to which both the central controller and the port microprocessor have access for the exchange of data. The central controller transfers data from the shared memories to a module output coupled to other components of the programmable controller. A removable memory cartridge stores a plurality of programs for execution by the port microprocessors to exchange data over the networks using different communication protocols. Configuration data is stored in the module defining which program is to be transferred from the memory cartridge into the shared memory of each port circuit.

  • Patent number: 5484995
    Abstract: A bar code reader and the mirror oscillating system thereof are disclosed herein. The bar code reader is of the type which produces a scanning light beam by oscillating at least one mirror with a electromagnetic oscillator. The electromagnetic oscillator includes a winding which is energized with an alternating current signal produced based upon a position signal generated by a magnetic pickup. The position signal is representative of the location of the mirror. The position signal is amplified, phase-shifted, and assigned a duration based upon the difference between the desired angle of mirror oscillation and the actual angle of oscillation to produce the alternating current signal which is applied to the winding. When applied to the winding, the alternating current produces an alternating magnetic field which interacts with a permanent magnet fixed relative to the mirror to oscillate the mirror.

  • Patent number: 5483142
    Abstract: A capacitor precharge circuit limits both peak DC link current and peak AC line current to any desired peak magnitude thereby providing for optimum precharge control and robust operation. The precharge circuit employs a microprocessor which implements a non-linear discontinuous current control scheme without the need for current sensors. The precharge circuit is well suited for use with an AC to DC converter having link inductor and a DC bus capacitor which requires precharging before full power is applied to the converter.

  • Patent number: 5483241
    Abstract: A millimeter wave radar is placed on an aircraft and several radar targets are placed near a runway. The targets are discrete objects, each having a relatively localized radar cross section, a unique signature or a unique range bin, and a position which is accurately known. Targets should be spread over the length of the runway. Radar corner reflectors and active or passive repeaters are preferred. The locations of the radar targets with respect to the runway can be transmitted to the aircraft, or they can be stored on board. On board memory requirements can be reduced by requiring all airports to select one of only a few standard target placement patterns, or even only one. Targets are inexpensive, as are radars whose only precision requirement is in range, and not in azimuth or elevation angles. Range to at least three targets in the radar's field of view is all that is required for an on-board computer to determine the aircraft's location.
