摘要： A device comprises a fuel line that carries a combustible fuel including gasoline, a first optical channel that evaluates a degree of absorption at a first wavelength spectrum of light transmitted through the combustible fuel within the fuel line, and a second optical channel that evaluates a degree of absorption at a second wavelength spectrum. The first and second wavelength spectrums consists of wavelengths of between about 800 nanometers (nm) and about 1200 nm. The device further comprises a controller configured to receive inputs from the first and second optical channels representing the degrees of absorption at the first and second wavelength spectrums, correlate the degrees of absorption with proportions of ethanol and water in the combustible fuel, and output data corresponding to the proportions of ethanol and water to a controller of a combustion engine fed with the combustible fuel.

The sensor further includes a voltage generator that generates a first voltage across the first Schottky diode and a second voltage across the second Schottky diode. When the first Schottky diode and the second Schottky diode are subjected to different strain, the integrated circuit measures the values of the currents flowing through the first Schottky diode and the second Schottky diode to determine the strain on an element where the first Schottky diode and the second Schottky diode are attached.

摘要： A device includes a resonator having an oscillating portion with dimensions chosen to lead to a desired resonant frequency. A light source is positioned to provide light along the length of the oscillating portion at a specific wave length. A detector detects a change in oscillation of the resonator responsive to the wave pressure produced by the light source heating a gas. The light source is modulated with a frequency the same as the resonant frequency of the resonator.

摘要： A system for detection of stress and deformation in a structural asset, for instance, one of reinforced concrete. An area on the asset may have a structure interface, such as a patch, attached to it with a fastening mechanism which may be a layer of an epoxy or other material, or be items such as screws, bolts, welds, or the like. One or more surface acoustic wave (SAW) strain sensors may be attached to the interface with an adhesive layer of epoxy or other material, or with mechanical items. Stress may be transmitted by the interface to the strain sensors. The sensors may be interrogated with a wire or wireless reader to obtain strain measurements. The measurements may indicate stress and deformations such as bulges and breaks in the asset. The measurements may also be a basis for determining location and extent of the stress and deformations.

摘要： A SAW sensor module can be produced with a true all quartz sensor package (TAQSP) attached to a substrate. The TAQSP has a quartz cover direct quartz bonded to a SAW sensor on a quartz substrate. The TAQSP can be mass produced by direct quartz bonding a quartz cover wafer, having many covers, to a quartz sensor wafer, having many sensors, thereby producing a wafer tandem. The wafer tandem can be further processed because the bond protects the sensors within. Individual sensor packages can be obtained by cutting stripes out of the cover wafer, revealing SAW sensor bonding pads, and then dicing the wafer tandem. A SAW sensor module results when the sensor packages are attached to an antenna bearing substrate and then sealed.
