    摘要： A radiation power detector includes a thermal membrane that produces a voltage responsive to temperature differences. A radiation absorber is thermally coupled to the thermal membrane, and an indicator is coupled to the thermal membrane responsive to the temperature differences. The indicator is powered by voltage produced by the thermal membrane and signals the amount of radiation power to which the absorbing material is exposed.

    摘要： A method includes creating Coriolis-based deflection in at least one oscillating flow tube of a flow meter, which is caused by material flowing through the at least one flow tube. The method also includes determining a deflection amplitude and deflection period using interferometric measurements. The method further includes determining a characteristic of the material using the amplitude and period and transmitting the characteristic. A laser interferometer could include a photo-detector. The deflection period could be based on variations in a period of fringes in the photo-detector's output. The deflection amplitude could be based on a number of fringes during the deflection period. A resonant frequency of the at least one flow tube can be determined using the deflection period, and a density of the material can be determined using the resonant frequency. The characteristic of the material could include a mass flow rate or a volumetric flow rate of the material.

    摘要： An apparatus includes a plurality of islands each carrying multiple cantilevers. The apparatus also includes a fluidic network having a plurality of channels separating the islands. The channels are configured to provide fluid to the islands, and the fluid at least partially fills spaces between the cantilevers and the islands. Heat from the islands vaporizes the fluid filling the spaces between the cantilevers and the islands to transfer the heat away from the islands while driving the cantilevers into oscillation. The apparatus may also include a casing configured to surround the islands and the fluidic network to create a vapor chamber, where the vapor chamber is configured to retain the vaporized fluid. The islands and the fluidic network could be formed in a single substrate, or the islands could be separate and attached together by a binder located within the channels of the fluidic network.

    摘要： A method of fabricating a thick silicon dioxide layer without the need for long deposition or oxidation and a device having such a layer are provided. Deep reactive ion etching (DRIE) is used to create high-aspect ratio openings or trenches and microstructures or silicon pillars, which are then oxidized and/or refilled with LPCVD oxide or other deposited silicon oxide films to create layers as thick as the DRIE etched depth allows. Thickness in the range of 10-100 μm have been achieved. Periodic stiffeners perpendicular to the direction of the trenches are used to provide support for the pillars during oxidation. The resulting SiO2 layer is impermeable and can sustain large pressure difference. Thermal tests show that such thick silicon dioxide diaphragms or layers can effectively thermally isolate heated structures from neighboring structures and devices within a distance of hundred of microns. Such SiO2 diaphragms or layers of thickness 50-60 μm can sustain an extrinsic shear stress up to 3-5 Mpa. These thick insulating microstructures or layers can be used in thermal, mechanical, fluidic, optical, and bio microsystems.
