We believe that successful combination of computer aided design (CAD) and multiphysics simulation tools with the state-of-the-art (SOTA) measurement methodology will contribute to reduction of high prototyping costs, long product development cycles, and time-to-market pressures while developing MEMS gyroscopes for various military and commercial applications. In our approach we combine a unique, fully integrated, software environment for multiscale, multiphysics, high fidelity analyses of MEMS gyroscopes with the SOTA optoelectronic laser interferometric microscope (OELIM) methodology. The OELIM methodology allows remote, noninvasive, full-field-of-view measurements of deformations with high spatial resolution, nanometer accuracy, and in near real-time. In this paper, both, the software environment and the OELIM methodology are described and their applications are illustrated with representative examples demonstrating viability of the hybrid approach, combining modeling and measurements, for the development of MEMS gyroscopes. These preliminary examples demonstrate capability of our approach to quantitatively determine effects of static and dynamic loads on the performance of MEMS gyroscopes.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.

This paper presents iterative consecutive mean excision (CME) algorithms that can be used for these purposes. One CME algorithm uses all the data in the initial step whereas a more powerful forward CME (FCME) algorithm uses only a small part of the data. Iteration is shown to be an advantage if compared to noniterative algorithms, but the benefits depend on signals to be cancelled. The CME algorithms also provide a direct way to set the interference detection threshold. The paper discusses the implementation and interference mitigation capability of the CME algorithms. In the simulations their performance is compared to noniterative similar kind of notch filter algorithms in a delay estimation problem. It is shown that these methods offer remarkable interference tolerance improvements especially against very narrowband interference and about 40 dB improvements in tolerable interference-to-signal ratio for interference whose bandwidth is up to 40 % of the bandwidth of the desired signal. It is also shown that averaging is an important element in interference cancellation in delay estimation if the bandwidth of the interference exceeds 10 % of the bandwidth of the desired signal.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.

The gyro is based on a novel, patented, planar magnetic actuator and position sensor configuration with a gyro wheel that is rotated by a multi-phase electromagnetic spin motor. The motor and actuator/sensor configurations, in addition to providing the necessary forces to suspend the spinning wheel, are amenable to fabrication using some of the developing MEMS fabrication technologies, making batch fabrication of the gyro possible. This will provide the capability for high production yield in high volume through the use of batch processing, without the need for skilled hand labor, resulting in high yields, high reliability and low cost of ownership. The gyro concept is described in detail. The high-speed rotation of the wheel, somewhat smaller than a dime, can produce an angular momentum much larger than that of the Coriolis force based MEMS gyros now receiving intensive development, and is expected to provide considerably higher performance than currently available from this class of instrument. Two axes of angular rate information and 3 axes of acceleration information are provided by the control loops that center the wheel within the case. Thus, two such magnetically suspended spinning wheel gyros can be used to implement a complete IMU, and can also provide redundancy in 4 of the 6 degrees of freedom.","PeriodicalId":102388,"journal":{"name":"PLANS 2004.
