摘要： A leak detector for a valve controlling flow of fuel to a combustion chamber employs a fuel concentration sensor in a sensing chamber placed downstream from the valve seat. The valve has a downstream chamber which is in communication by diffusion through an orifice, with a source of pressurized air. By injecting air into the downstream chamber through this orifice after the valve has closed and then measuring with the sensor the fuel concentration within the sensing chamber, excessive fuel leakage by the valve can be detected.

摘要： A highly sensitive fluid composition analyzer where a fluid may be placed in contact with a very small area on a material sensitized to change color in the presence of a specific type of compound, to be impinged with light. The light reflected, transmitted and/or scattered by the material may serve as input for the analyzer electronics. The fluid may be pre-concentrated prior to being brought in contact with the material. The area on the material may be a spot having an outside dimension of less than one millimeter.

摘要： A flow sensor is provided having a substrate with a sensing element and flow channel aligned over the sensing element. The sensing element senses at least one property of a fluid. The flow channel is aligned by one or more guide elements formed in an alignment layer. The flow channel across the sensing area is accurately and precisely aligned due to the guide elements provided at the wafer-level, facilitating reliable, low-cost, and consistent results among multiple flow sensors. The flow sensor is adapted for use in harsh environments.

摘要： A gas valve body with a first flow chamber and, a second flow chamber including and a main valve positioned in line and between the first flow chamber and the second flow chamber. The main valve can be opened by creating a pressure differential across the main valve. An electrostatically controlled pilot valve is provided for controlling the pressure differential across the main valve for “on-ff” operation. The electrostatically controlled pilot valve may also be operated to “modulate” the pressure differential across the main valve along a range of pressure differential values.

摘要： Embodiments of the present invention relate to detector structures for use in a micro gas analyzer, preferably in a differential setup. The detector structures may comprise one or more detector types, such as photo-ionization (PID), electron capture (ECD), ion mobility (IMS), differential mobility (DMS), ion-trap mass spectrometer (ITMS), in which all are provided with ions and electrons from one vacuum ultra violet (VUV) source. This source may also provide ions for ion-based gas pumps.

摘要： A sensor system for detecting the presence of at least one specific component in a fluid medium such as an exhaust gas. A sensor is mounted in a sensor body for detecting the presence of at least one specific component and providing a representative signal that is transmitted to a remote receiver for processing. A power source such as a thermopile provides power for the sensor and the transmitter. Preferred are sensors that detect a plurality of different components in the gas and provide a distinct signal for each component. A preferred transmitter is designed to transmit at a low duty cycle so as to conserve power. A preferred sensor is electronic, has the capability for self-diagnostics and self-calibration, and causes a change in current when exposed to the component, such as a functionalized field effect transistor.

摘要： Selecting a stationary phase for a fluid analyzer using certain criteria to determine an appropriate material for use in, for instance, a micro fluid analyzer. High absorption of an analyte or sample, low water sorbency and high porosity or permeability of the material may be sought. A selected material may incorporate a toughening agent using a neutral leaving group. A selected material may have a capping agent to promote hydrophobicity. A selected material may be a hydrophobic polymer. The selection of a stationary phase may involve molecular modeling.
