| 20080284544 | Mems Filter Device and Manufacturing Method Thereof - An object of the invention is to provide a coupling element of an MEMS filter with design flexibility and minimization of mass loading effects. The invention provides a structure wherein the mass loading effects are not reflected on the MEMS filter characteristic by using a nanosize coupling element with a very small mass compared to a microsize MEMS resonator, such as a carbon nanotube (CNT), as a coupling element part. | 11-20-2008 |

| 20100219914 | WIRING NANOSCALE SENSORS WITH NANOMECHANICAL RESONATORS - A system, device, method, and apparatus provide the ability to wire a voltage sensitive device to a nanoelectromechanical system (NEMS) resonator. A voltage sensitive device is configured to detect one or more voltage signals and output one or more electrical potentials in real-time. An array of piezoelectric NEMS resonators (with each resonator tuned to a unique frequency) is used to receive the output electrical potentials and convert each output electrical potential to a corresponding resonance frequency varying signal. The output signal from each resonator varies in linear proportion to the resonator's corresponding frequency variation arising from the applied elecrical potential. The frequency varying signals are multiplexed together into a single readout signal path that is monitored to determine variations in vibrational amplitude. A demodulation device deconvolves the multiplexed frequency varying signals to recover and uniquely identify the output electrical signal. | 09-02-2010 |

| 20090009269 | Resonator System Such As A Microresonator System And Method Of Making Same - A resonator system such as a microresonator system and a method of making same are provided. In at least one embodiment, a mechanical circuit-based approach for boosting the Q of a vibrating micromechanical resonator is disclosed. A low Q resonator is embedded into a mechanically-coupled array of much higher Q resonators to raise the functional Q of the composite resonator by a factor approximately equal to the number of resonators in the array. The availability of such a circuit-based Q-enhancement technique has far reaching implications, especially considering the possibility of raising the functional Q of a piezoelectric resonator by merely mechanically coupling it to an array of much higher Q capacitively-transduced ones to simultaneously obtain the most attractive characteristics of both technologies: low impedance from the piezo-device and high-Q from the capacitive ones. Furthermore, the manufacturing repeatability of such micromechanical resonator-based products is enhanced. | 01-08-2009 |
