Abstract: A System and Method for Gas Recognition by Analysis of Bispectrum Functions is based on the Higher-Order Spectral analysis of time series measurements of resistance fluctuations in Metal Oxide Semiconductor (MOS) gas sensors, such as Taguchi-type sensors. A two-dimensional contour plot module of the bispectrum function is treated as a pattern. These patterns include information about the analyte(s) whereby characteristics of the gas can be identified.

Abstract: A System and Method of Molecule Counting Using Fluctuation Enhanced Sensors includes processes for improved chemical analyte detection and quantification through the measurement and generation of an amplitude density histogram of the measured time series of frequency fluctuations in the instantaneous frequency of a chemical sensor arranged to produce an oscillatory output signal when exposed to chemical substances. The system and method may use a chemical sensor, such as a surface acoustic wave (SAW) device. Statistical analysis produces the amplitude density of the frequency fluctuations, which are represented as a pattern that includes information about the quantity of the analyte on the surface of the sensor. Patterns in the measured amplitude density are then correlated to theoretical amplitude density functions in order to determine the number of analyte molecules on the surface of the sensor.

Abstract: A system and method of fluctuation enhanced gas-sensing using SAW devices includes processes for improved chemical analyte detection, identification, and quantification through the measurement and spectral analysis of frequency fluctuations in the instantaneous frequency of a chemical sensor arranged to produce an oscillatory output signal when exposed to chemical substances. The system and method may use a chemical sensor, such as a surface acoustic wave (SAW) device. The spectral analysis produces the power spectral density of the frequency fluctuations, which are represented as a pattern that includes information about the analyte(s) such as, total adsorbed gas mass and diffusion coefficients. The diffusion coefficients may then be used to determine the number of molecule types and/or the concentration of each.

Abstract: The present invention provides a method for detecting bacteria and a nano-well device having one or more input/output connections about a gap and one or more bacteriophages at or about the gap that trigger a detectable electrical field fluctuation when the one or more bacteriophages contact a cognate target within a liquid sample.
