Abstract:
1. A gyroscope that detects angular velocity comprising: a first structure including a first proof mass wherein the first proof mass oscillates in a driving direction, wherein a Coriolis force acts on the first proof mass in a sensing direction that is orthogonal to the driving direction when the gyroscope is rotated with an angular velocity about an input axis orthogonal to the driving and sensing directions; a spring system compliant in a first direction of motion, coupled to the first structure, the spring system comprising a first flexible element; a rigid element coupled to the first flexible element; and a second flexible element coupled to the rigid element, wherein the first flexible element and the second flexible element, each has a longitudinal axis parallel to the first direction of motion, wherein the first structure and spring system are disposed substantially in a plane; wherein when a force is applied to the spring system, the first and second flexible elements deflect and the rigid element rotates; and a transducer responsive to the Coriolis force acting on the first proof mass.
