Towards Inertial Grade Vibratory Microgyros: a High-q In-plane Silicon-on-insulator Tuning Fork Device
This paper reports on the design and implementation of an in-plane solid-mass single-crystal silicon tuning fork gyro that has potential to achieve inertial-grade performance. A novel design is devised to achieve high Q in the drive and sense resonant modes (Qdrive=84,000 and Qsense=64,000) with effective decoupling. The gyroscope was fabricated on 40μm SOI using a two-mask process. The drive a...
متن کاملThe tuning fork as a method of measuring vibratory perception in osteoarthritis of the knee
Vibratory Perception Threshold (VPT) is a sensory measure that is commonly used to evaluate diabetic neuropathy and has been associated with neuropathic arthropathy. Studies at our institution have shown that subjects with knee OA and hip OA have generalized vibratory sense deficits with impaired VPT at the upper and lower extremities compared to age matched controls. 2 Current hypotheses for t...
متن کاملError Model and Compensation of Bell-Shaped Vibratory Gyro
A bell-shaped vibratory angular velocity gyro (BVG), inspired by the Chinese traditional bell, is a type of axisymmetric shell resonator gyroscope. This paper focuses on development of an error model and compensation of the BVG. A dynamic equation is firstly established, based on a study of the BVG working mechanism. This equation is then used to evaluate the relationship between the angular ra...
متن کاملTuning Fork Tests
This article reviews the history of tuning fork tests, its current status as a clinical examination tool. All the commonly performed tuning fork tests are discussed in detail. The three commonly performed tuning fork tests include: Rinne test, weber test and Absolute bone conduction test.
متن کاملCharacterization of the Bell-Shaped Vibratory Angular Rate Gyro
The bell-shaped vibratory angular rate gyro (abbreviated as BVG) is a novel shell vibratory gyroscope, which is inspired by the Chinese traditional bell. It sensitizes angular velocity through the standing wave precession effect. The bell-shaped resonator is a core component of the BVG and looks like the millimeter-grade Chinese traditional bell, such as QianLong Bell and Yongle Bell. It is mad...
