Claim Text:
1. A method for exciting a resonator having a resonant frequency, comprising the steps of: exciting the resonator during a first time period with a first frequency which differs from the resonant frequency by a first frequency difference; exciting the resonator during a second time period with a second frequency, wherein the said second frequency differs from the resonant frequency by a second frequency difference, wherein the first frequency difference and the second frequency difference have different signs, wherein the magnitudes of the first frequency difference and the second frequency difference differ by less than 10% of the larger magnitude; and one of the following steps a) and b): a) increasing the first frequency difference and the second frequency difference to reduce an oscillation amplitude of the resonator; and b) reducing the first frequency difference and the second frequency difference to increase an oscillation amplitude of the resonator.
