  • Vibrating resonator inertial rotation sensor
    Patent number: 7093488
    Abstract: The inertial rotation sensor comprising a vibrating resonator associated with transducers defining a pair of control channels and a pair of detection channels, preferably comprises a single multiplexer member for all of the channels, the multiplexer member being associated with a processing unit generating cycles comprising control action times on each control channel followed by detection action times on each detection channel, with two succession action times being separated by a relaxation time.
    Type: Grant

  • Method of compensating anisotropy in a vibrating-bell inertial rotation sensor
    Publication number: 20050126257
    Abstract: The method serves to compensates anisotropy in an inertial rotation sensor comprising a metallized vibrating bell (1) having a bias voltage applied thereto, the vibrating bell (1) having an edge (7) electrodes (5.1, 5.2), and the method comprises the steps of measuring, preferably by multiplexing, the anisotropy between the electrodes and of applying to the electrodes a fraction of the bias voltage that depends on the differences measured between the electrodes.
