Patent ID: 7915965

Claim:
An oscillator comprising: a plurality of resonator portions, each said resonator portion having an active resonance region defined between a set of electrodes capable of receiving, by electrical coupling, signals caused by oscillator resonance in said active resonance region during operation of said oscillator, each of said resonator portions being a cantilever-mounted resonator portion that is mounted in said oscillator using one or more mountings, each resonator portion comprising first and second ends, the first end of each resonator portion being mounted to a substrate via at least one of said mountings, the second end of each resonator portion being free, each active resonance region having a relatively large acceleration sensitivity along a dominant axis and relatively small acceleration sensitivities along axes orthogonal to said dominant axis, said resonator portions being cantilever-mounted in said oscillator to direct the acceleration sensitivities, of the respective active resonance regions along their respective dominant axes, in substantially opposite directions so as to reduce the sensitivity of the oscillator to acceleration.
