Abstract:
1. A resonator comprising: a frame; a first oscillator configured to oscillate with respect to the frame; a first driver configured to drive the first oscillator at the first oscillator's resonant frequency; a first half of a first relative position switch mounted to the first oscillator; a second oscillator having substantially the same resonant frequency as the first oscillator, wherein the first and second oscillators are designed to respond in substantially the same manner to external perturbations to the frame; a second half of the first relative position switch mounted to the second oscillator; and wherein as the first oscillator oscillates there is relative motion between the first and second oscillators such that the first relative position switch passes through a closed state in each oscillation when the first and second switch halves of the first relative position switch pass by each other.
