    • A technique is provided for determining a force/acceleration acting on a proof mass of a bistable device. According to a first aspect of the invention, the location of a boundary of one of the stable configurations of the device is monitored and compared to a predetermined location of the same boundary corresponding to a condition in which the force/ acceleration is absent, to detect a deviation of said location. The deviation is used to determine the force/acceleration. According to another aspect of the invention, the resonance frequency of the proof mass oscillation in one of the stable regions is monitored, and compared to a predetermined resonance frequency of the proof mass oscillation in the same region corresponding to a condition in which the force/acceleration is absent, to determine a deviation of the resonance frequency due to the presence of force/acceleration. The deviation in the resonance frequency is used to determine the force/acceleration.
    • 提供了一种用于确定作用在双稳态装置的检验质量块上的力/加速度的技术。 根据本发明的第一方面,监测装置的稳定配置之一的边界的位置并将其与对应于不存在力/加速度的状况的相同边界的预定位置进行比较以检测 所述位置的偏差。 偏差用于确定力/加速度。 根据本发明的另一方面,监测其中一个稳定区域中的检验质量振荡的共振频率,并将其与在相同区域中的检验质量振荡的预定谐振频率相对应, 不存在加速度,以确定由于存在力/加速度而导致的共振频率的偏差。 谐振频率的偏差用于确定力/加速度。
