ABSTRACT:
A vibrating gyroscope includes a ring-shaped vibrator having a node. A driver element is provided to cause the vibrator to vibrate flexurally. A detector element is formed along an axis of the vibrator and has a surface disposed such that the surface is non-perpendicular to a direction of vibration of said vibrator while the vibrator remains stationary. In one embodiment, the vibrator is metallic and the driver and detector are piezoelectric elements. In another embodiment, the vibrator is piezoelectric and the driver and detector are metal electrodes.
