    Abstract: A differential microdischarge detector system. The system comprises two microdischarge detectors (MDDs). One of the MDDs is connected to receive sample analytes to be measured, while the other MDD is connected to receive a reference sample that contains interfering gases and none or a much lower concentration of the sample analytes to be measured. The outputs of the two MDD's are fed to a circuit that generates either a difference or a ratio between the measurements of the two MDDs. In addition, the current, impedance or voltage across the electrodes of the two MDDs may be measured and processed to generate either a difference or a ratio signal, thus obtaining additional information about the sample gas analytes.

    Abstract: A system for effecting a soft or gentle ionization technique to avoid fragmentation of analyte molecules provided to a micro mass spectrometer for analysis. To ionize the analyte molecules, the system may be based on proton transfer reaction (PTR) for ionization, UV light to generate either positive or negative ions, or E-field ionization. For example, with PRT, there may be a water generator for providing H2O to an ion generator. H3O+ may be provided by the generator to a charge transfer reactor that brings a stream of H3O+ molecules together with analyte molecules. Then, H+ atoms may be transferred from the H3O+ molecules to the analyte molecules without breaking up or fragmenting the respective analyte molecules. The ionized molecules may be provided to a micro mass spectrometer for analysis.

    Abstract: A method and apparatus for sensing a flammable vapor are described herein. Initially, a first thermal conductivity of a vapor at a first temperature and a second thermal conductivity of the vapor at a second temperature can be determined. Thereafter, a ratio of the first thermal conductivity signal to that of the second thermal conductivity can be calculated to obtain a primary “vapor” signal. The “vapor” ratio can then be compared to an “air” ratio of air without the vapor at the first temperature and the second temperature to obtain a secondary signal thereof. Such a secondary signal can then be compared to an alarm set-point value to thereby determine whether the vapor comprises a flammable vapor and a risk-reducing action thereof be taken.

    Abstract: An apparatus to normalize a flow rate of a fluid in a main flow channel is provided. The apparatus uses a movable member, such as a flexible membrane disposed for reciprocating displacement, to produce a constant dither flow of the fluid that is independent of fluid composition. This dither flow generates a signal output from a normalizing flow sensor that both represents a characteristic property of the fluid and a flow rate calibration factor. A similar apparatus to determine the characteristic property or flow rate calibration factor is also provided. The devices disclosed may be used in numerous industrial, process, and medical flow system applications for normalization of flow sensors and to derive other properties of a fluid.

    Abstract: A microsensor housing having a structure with at least one inlet at one end and a thermal property sensor at the other end. Situated between the inlet and the sensor is a convection shield. Sampled fluid is taken in the inlet from a channel carrying the fluid to be sampled. The convection flow lines of the fluid are barred by the convection shield. The fluid is diffused into a cavity between the shield and sensor. The sensor detects a thermal property of the diffused fluid. One preferred shield has holes about its perimeter with a solid center part of the shield covering at a distance the sensor. The channel carrying the fluid may have screens to reduce turbulence noise and to aid in fluid transport to and from the sensor housing.
