| 20090267699 | TIMING OSCILLATORS AND RELATED METHODS - Timing oscillators as well as related methods and devices are described. A timing oscillator may include a mechanical resonating structure with major elements and minor elements coupled to the major element. The timing oscillator can generate stable signals with low phase noise at very high frequencies which allows a timing oscillator to be used effectively in a number of devices including computers and mobile phones for time and data synchronization purposes. The signal generated by the timing oscillator can be tuned using a driver circuit and a compensation circuit. | 10-29-2009 |

| 20100301703 | INTEGRATION OF PIEZOELECTRIC MATERIALS WITH SUBSTRATES - Devices having piezoelectric material structures integrated with substrates are described. Fabrication techniques for forming such devices are also described. The fabrication may include bonding a piezoelectric material wafer to a substrate of a differing material. A structure, such as a resonator, may then be formed from the piezoelectric material wafer. | 12-02-2010 |
| 20100314969 | MECHANICAL RESONATING STRUCTURES AND METHODS - Apparatus and methods of connecting mechanical resonating structures to a body are described. Multi-element anchors may include a flexible portion that flexes when the mechanical resonating structure vibrates. The flexible portion may have a length related to the resonance frequency of the mechanical resonating structures. Some of the multi-element anchors include elements that are oriented perpendicularly to each other. MEMS incorporating such structures are also described. | 12-16-2010 |
| 20110121682 | SIGNAL AMPLIFICATION BY HIERARCHAL RESONATING STRUCTURES - An electromechanical resonating structure, including: first level major elements coupled to each other to form a second or higher level hierarchy; and first level sub-micron size minor elements with a characteristic frequency and coupled to each of the first level major elements to form a second level hierarchy in which a signal is effectively amplified by vibrating each of the plurality of major elements in at least one mode determined by the geometry and dimensions of the first level sub-micron minor elements. | 05-26-2011 |

| 20090294638 | Nanomechanical Oscillator - A mechanical oscillator has components with dimensions in a sub-micron range to produce resonance mode oscillations in a gigahertz range. A major element is coupled to a minor, sub-micron element to produce large amplitude gigahertz frequency oscillation that is detected with readily available techniques. The mechanical structure can be formed according to a number of geometries including beams and rings and is excited with electrostatic, magnetic and thermal related forces, as well as other excitation techniques. The mechanical structure can be arranged in arrays for applications such as amplification and mixing and is less sensitive to shock and radiative environments than electrical or optical counterparts. | 12-03-2009 |
