  • Extraction of double-oscillation-frequency sinusoids in vibratory rotation sensors
    Patent number: 6158282
    Abstract: The invention is a vibratory rotation sensor comprising a housing, a resonator attached to the housing, first and second sets of electrodes, and a signal processor. One set of electrodes are attached to the housing and the other set of electrodes are attached to the resonator, the first set opposing the second set. Each set consists of one or more electrodes. The signal processor has one or more input ports capacitively connected to one or more of the first set of electrodes, the signal processor extracting from the signals appearing at the one or more input ports one or more double-frequency sinusoids having frequencies of twice the frequency of oscillation of the resonator.
