摘要： PROBLEM TO BE SOLVED: To provide a small-sized, low-output, and low-cost MEMS accelerometer or gyroscope for a small-sized low-output navigation-class inertia system for an autonomous moveable body. SOLUTION: This vibration gyroscope using a cylindrical ring resonator is equipped with a folded cylinder suspension for supporting the ring resonator. The cylinder suspension is equipped with an inner cylinder, an outer cylinder, and an annulus. The inner cylinder, the outer cylinder, and the annulus are concentric. A top edge of the inner cylinder is coupled with an inner edge of the annulus. A top edge of the outer cylinder is coupled with an outer edge of the annulus. These structures, including drive and detection electrodes, are manufactured on an SOI wafer by using semiconductor manufacturing technologies. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce the coupling of vibration energy to the mounting bench. SOLUTION: The apparatus in one embodiment may have: a beam having at least first and second mounting points that are operatively coupled to the beam by first and second flexures respectively; the beam having first and second nodal points; the beam having a center area; and an altered mass content in a vicinity of the center area, the altered mass content being such that the first and second nodal points are substantially aligned with the first and second flexures. The beam is therefore supported at the nodal points for the fundamental mode of vibration. COPYRIGHT: (C)2007,JPO&INPIT
