MICROMECHANICAL VIBRATORY GYROSCOPE-ACCELEROMETER Russian patent published in 1996 - IPC

FIELD: inertial measuring systems, autopilots of model aeroplanes and ships and safety systems of transport facilities. SUBSTANCE: gyroscope-accelerator represents a system of two pendulums constructionally made in the form of external and internal flat members that are connected to each other and to the base by means of torsion bars. The axes of the torsion bars, coupling the internal member to external one, and the external member to the base are mutually perpendicular. Positioned in the center of the internal member is the inertia mass with a shifted center of inertia relative to the geometric center of the internal member. Legitimate signal is picked off attitude sensor realized with the aid of electrodes located on the internal member and base and fed to preamplifier and main phase-sensitive rectifier, and then, via a separation filter to the auxiliary filter and phase-sensitive rectifier. Output signal of the auxiliary filter will be proportional to acting linear acceleration and output signal of auxiliary phase-sensitive rectifier will proportional to the acting angular velocity. EFFECT: improved design. 7 cl, 5 dwg
