摘要:
A longitudinal mode resonator that includes a substrate and a bar that is suspended relative to the substrate. The bar is suspended such that it is free to expand and contract longitudinally in response to the application of an electric field across its thickness. The expansion and contraction of the bar achieves resonance in response to the field having a frequency substantially equal to the fundamental frequency of the bar.

摘要:
A tuning fork gyroscope typically including at least one proof mass with an upper sense plate disposed above the proof mass and a lower sense plate disposed below the proof mass and means for sensing changes in the nominal gaps between the sense plate and the proof mass and for outputting a signal indicative of the gyroscope angular rate.
摘要:
A method for reducing errors in a tuning fork gyroscope includes determining a first distance, gt, between an upper sense plate and a proof mass and a second distance, gb, between a lower sense plate and the proof mass. The method further includes applying a first voltage, Vt, to the upper sense plate and a second voltage, Vb, to the lower sense plate, wherein the ratio of the first voltage and the second voltage is a function of the first distance and the second distance.
摘要:
In various embodiments, an inductance of an inductor is tuned by adjusting a position of a conductor and/or a magnetic material with respect to a conducting wire of the inductor, thereby changing the electro-magnetic characteristics of the conducting wire. The conductor and/or magnetic material can be disposed in a microfluidic channel and can be moved within the microfluidic channel using a suitable actuator mechanism.
摘要:
An electromagnetic composite metamaterial including an electromagnetic medium and a plurality of spaced electromechanical resonators disposed in or on the electromagnetic medium configured to control electromagnetic wave propagation properties in the electromagnetic composite metamaterial.
