  • Patent number: 5379223
    Abstract: An inertial measurement and navigation system using a multisensor which provides analog acceleration and rate information to an analog to digital converter whose digital output is processed by a digital demodulator and fed to an AHRS systems processor whose output is fed to a digital to analog converter. Output information from the digital to analog converter can be stored or used to provide information to the pilot oil cockpit displays. The digital demodulator includes a phase locked loop comprising a Hilbert transform phase detector, a first order IIR loop filter and a digital controlled oscillator which provides in-phase and quadrature reference signals used in demodulation.

  • Patent number: 5115201
    Abstract: A digital demodulator utilizes voltage to frequency converters, digital counters and a computer to combine demodulation and analog to digital conversion into one step, therefore providing for in-phase and quadrature demodulation of amplitude modulated double sideband suppressed carrier signals. Accleration sinusoidal signals and phase reference pulses are input to a voltage to frequency converter and counter board which interfaces to a computer where the signals are demodulated using a digital demodulation scheme.
