    摘要： 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.

    摘要： A memory device includes a mechanical element that exhibits distinct bistable states under amplitude modulation. The states are dynamically bistable or multi-stable with the application of a drive signal of a given frequency. The natural resonance of the element in conjunction with a hysteretic effect produces distinct states over a specific frequency range. Devices with multiple elements that respond to different frequency ranges provided on a common contact are formed with improved density. The devices may be excited and read with magnetomotive, capacitive, piezoelectric and/or optical methods. The devices may be planar oriented or out of plane oriented to permit three dimensional memory structures. DC biases may be used to shift frequency responses to permit an alternate method for differentiating states of the element.

    摘要： 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.

    摘要： An apparatus is described that includes a substrate having a first plate and a second plate. The first plate and the second plate collectively have a first mode when excited by a drive signal and have a second mode when excited by a gyroscopic effect. The first and second plates each include a temperature-compensated stack having first and third layers that have a stiffness that increases with increasing temperature over a temperature range with a second layer between the first and third layers, where the second layer is formed from a different material than the first and third layers.
