Method, apparatus and system for providing metering of acceleration

摘要

Techniques and mechanisms to provide for metering acceleration. In an embodiment, a microelectromechanical accelerometer includes a magnet, a mass, and a first support beam portion and second support beam portion for suspension of the mass. Resonance frequency characteristics of the first support beam portion and second support beam portion, based on the magnet and a current conducted by the first support beam portion and second support beam portion, are indicative of acceleration of the mass. In another embodiment, the accelerometer further includes a first wire portion and a second wire portion which are each coupled to the mass and further coupled to a respective anchor for exchanging a signal with the first wire portion and the second wire portion. The first wire portion and the second wire portion provide for biasing of the mass.

1. An apparatus comprising:
a microelectromechanical accelerometer including:
a mass;a first magnet to generate a magnetic field;a first support beam portion and a second support beam portion each to conduct a time varying signal which traverses the magnetic field along a first dimension, wherein a resonance frequency for the time varying signal is based on the magnetic field, wherein the mass is suspended with the first support beam portion and the second support beam portion;a first wire portion coupled to the mass and flexibly coupled to a first anchor; anda second wire portion coupled to the mass and flexibly coupled to a second anchor, wherein the first anchor and the second anchor to exchange a first signal with the first wire portion and the second wire portion, wherein, based on the first signal and the magnetic field, the first wire portion and the second wire portion to impose a force on the mass along a second dimension perpendicular to the first dimension.
