Integrated Microelectromechanical Gyroscopes

Microelectromechanical ~MEMS! gyroscopes have wide-ranging applications including automotive and consumer electronics markets. Among them, complementary metal-oxide semiconductor-compatible MEMS gyroscopes enable integration of signal conditioning circuitry, multiaxis integration, small size, and low cost. This paper reviews various designs and fabrication processes for integrated MEMS gyroscop...

Ambulatory Gait Analysis Using Gyroscopes

Recently, technical progress has made possible to realize miniature kinematic sensors such as accelerometers and angular rate sensors (Sparks et al. 1998). These sensors can be battery powered and are promising tools for ambulatory gait monitoring and analysis. The possibility to detect simple parameters such as steps and cycle time from trunk or heel acceleration has already been demonstrated ...

Stable fiber-source gyroscopes.

We describe two new configurations of fiber gyroscopes that use superfluorescent fiber laser sources. In the first configuration we introduce a backward-pumping technique that achieves an order-of-magnitude increase in the power that can be launched into the gyroscope without instabilities. In the second configuration we employ the optical gain of the superfluorescent fiber laser source to ampl...

A dynamical envelope model for vibratory gyroscopes

In this contribution, a method will be presented to derive an envelope model for vibratory gyroscopes capturing the essential ”slow” dynamics (envelope) of the system. The methodology will be exemplarily carried out for a capacitive gyroscope with electrostatic actuators and sensors. The resulting envelope model can be utilized for both transient and steady state simulations with the advantage ...
