Patent ID: 8266961

Claim:
A MEMS gyroscope comprising: a first resonator configured for sensing rotation about a first axis x in a device plane, the first resonator including a first pair of shuttles suspended by a first plurality of suspension flexures and interconnected by a first fork, the first plurality of suspension flexures configured to allow the first pair of shuttles to be rotationally dithered in the device plane and to tilt out-of-plane about respective tilt axes y 1 and y 2 perpendicular to the first axis, each of the suspension flexures suspending the first pair of shuttles including at least one elongated member and at least one shorter member arranged such that the elongated member is parallel to the respective tilt axes; a second resonator configured for sensing rotation about a second axis y normal to the first axis in the device plane, the second resonator including a second pair of shuttles suspended by a second plurality of suspension flexures and interconnected by a second fork, the second plurality of suspension flexures configured to allow the second pair of shuttles to be rotationally dithered in the device plane and to tilt out-of-plane about a tilt axis x 2 perpendicular to the second axis, each of the suspension flexures suspending the second pair of shuttles including at least one elongated member and at least one shorter member arranged such that the elongated member is parallel to the tilt axis; a first set of Coriolis sensing electrodes underlying the first pair of shuttles and positioned along an axis x 1 parallel to the first axis to sense tilting of the first pair of shuttles about their respective tilt axes y 1 and y 2 ; and a second set of Coriolis sensing electrodes underlying the second pair of shuttles and positioned along the first resonator tilt axes y 1 and y 2 to sense tilting of the second pair of shuttles about their tilt axis x 2 .
