for stämgaffelgyro intended elektrodmönster

摘要

The invention relates to an electrode pattern arranged on the freely vibrateable legs on a tuning fork-controlled gyro. The electrode pattern comprises drive electrodes for generating a vibration in the legs of the tuning fork and sensing electrodes for sensing vibrations which occur in the legs. The sensing electrodes comprise a first electrode configuration (sensor electrodes) for sensing vibrations either out of the plane (24, 25, 26, 27) or in the plane (7, 8, 9, 10, 11, 12) of the tuning fork and a second electrode configuration (feed back electrodes) for sensing vibrations in the plane (34, 35, 41, 42) or out of the plane, (9, 10, 11, 12) of the tuning fork, for controlling the driving of the tuning fork in the plane or out of the plane, respectively.
