Abstract
An inertial sensor is described in which a resonant element is driven by control electronics into resonance. The control electronics includes an oscillator. A circuit is provided for matching the frequency of the oscillator with the frequency of the output of the resonant element such that the time to operation from start up of the sensor is minimized and the requirement of frequency matching a given sensor to the control electronics is removed.
Claims8
An inertial sensor comprising an element having a resonant frequency, the element being driven to resonance by a driver, the sensor further comprising electronic control means including an oscillator capable of oscillation at variable frequencies in which the sensor further comprises comparator means for comparing the frequency of the output of the element with the frequency of the oscillator and locking the frequency of the oscillator once a predetermined frequency is achieved.
