摘要: A system and method for compensating for gradients in a dual cavity device such as but not limited to an accelerometer. A first source drives a first cavity at least two different modes, at least one mode varying with changes in cavity length. A second source drives a second cavity at least two different modes, at least one mode varying with changes in cavity length. A processor determines changes in cavity length as a function of both modes in both cavities to compensate for non-uniform behavior between the cavities.

摘要: An electronic device includes a substrate and a plurality of sensors. Each sensor is disposed in a well over the substrate and includes a working electrode, an inner filling solution disposed thereover, and an ion-selective membrane. The working electrode is in contact with the substrate and the ion-selective membrane is disposed over the inner filling solution and substantially seals the well.

摘要: An in-line loss-on-ignition measurement system includes an on-site extractor subsystem configured to collect fuel or a combustion by-product from a hydrocarbon fuel burning plant. An on-site analyzer is configured to receive the collected matter from the extractor subsystem and configured to weigh the collected matter, burn the collected matter, and weight the collected matter again. A controller is responsive to the analyzer and is configured to determine the loss-on-ignition data for the plant based on the weight of the collected matter before and after it is burned in the analyzer.

摘要: Apparatus and methods for performing a Fourier transform mechanically, using an array of one or more resonators. By tuning the resonators so that their natural frequencies correspond to harmonics of an input signal, the vibration of the resonators in response to the input signal may be measured to provide phase and amplitude information that is equivalent to the Fourier coefficients of the input signal. Preferably, the resonators are microelectromechanical (MEMS) resonators. Using MEMS resonators, the Fourier transform of a signal can be determined using substantially less power than would be consumed by a digital signal processor (DSP) or microprocessor performing similar calculations. MEMS resonator-based apparatus and methods according to various embodiments may be used for applications including compression and image processing.
