The cooling system includes a plurality of individual piezoelectric cooling elements spatially arranged in an array extending in at least two dimensions, a communications interface and driving circuitry. The communications interface is associated with the individual piezoelectric cooling elements such that selected individual piezoelectric cooling elements within the array can be activated based at least in part on heat energy generated in the vicinity of the selected individual piezoelectric cooling elements. The driving circuitry is associated with the individual piezoelectric cooling elements and is configured to drive the selected individual piezoelectric cooling elements.

摘要： The present invention generally relates to MEMS devices and methods for their manufacture. The cantilever of the MEMS device may have a waffle-type microstructure. The waffle-type microstructure utilizes the support beams to impart stiffness to the microstructure while permitting the support beam to flex. The waffle-type microstructure permits design of rigid structures in combination with flexible supports. Additionally, compound springs may be used to create very stiff springs to improve hot-switch performance of MEMS devices. To permit the MEMS devices to utilize higher RF voltages, a pull up electrode may be positioned above the cantilever to help pull the cantilever away from the contact electrode.

摘要： A resonator element capable of improving impact resistance is provided. A quartz crystal resonator element is a resonator element formed by etching a Z plate which is cut at predetermined angles with respect to the crystal axes of a quartz crystal. The quartz crystal resonator element includes a base, a pair of resonating arms extending from the base in the Y-axis direction, and a positive X-axis notch and a negative X-axis notch formed by notching the base in the X-axis direction. The positive X-axis notch is formed by notching the base from the negative side of the X axis towards the positive side so that the width of the positive X-axis notch increases as it approaches the outer circumference.
