Patent ID: 6938483

Claim:
A mechanical resonator pair comprising, at least: a first mechanical resonator comprising, at least: a resonating mass; a driving mechanism through which the resonating mass of said first mechanical resonator is driven to resonate along a pre-selected axis; a driving feedback mechanism that provides status information of the resonance of said first mechanical resonator along the pre-selected axis wherein the status information of the resonance includes amplitude, frequency, and phase of the resonance; a second mechanical resonator with the resonance of said second mechanical resonator phase-locked to the resonance of said first mechanical resonator with certain preset phase difference comprising, at least: a resonating mass; a driving mechanism through which the resonating mass of said second mechanical resonator is driven to resonate along the same pre-selected axis of said first mechanical resonator; a driving feedback mechanism that provides status information of the resonance of said second mechanical resonator along the pre-selected axis wherein the status information of the resonance includes amplitude, frequency, and phase of the resonance; a frequency adjustment mechanism through which a natural resonant frequency for the resonance along the pre-selected axis of said second mechanical resonator can be adjusted by a signal.
