Abstract: A sensor system issues measurement commands at a predetermined regular rate. If a measurement indicates that a gas of interest is present, then the sensor system is signaled to wake-up thereby pulsing a heater for the sensor element that improves the accuracy of measurements. Measurements of humidity, temperature and gas concentration are made. If the gas of interest is detected then the data is used to indicate a compensated gas measurement. The gas level is classified as to its hazard and an adaptive detection algorithm is used to set an activity mode. If the gas of interest is not detected, the adaptive detection algorithm is used to set a sleep mode that saves power. Measurement rates are kept constant while heater power is controlled to reduce power consumption. Measurement rates are changed to increase concentration sensitivity.

Abstract: A multicapillary bundle for use in a gas chromatograph. Each of the capillaries in the bundle is formed using a coating solution containing a stationary phase and a solvent. The capillaries are coated with the stationary phase by reducing pressure at a vacuum end of the capillary and creating a moving interface between the coating solution and a film of the stationary phase deposited on each of the capillaries. The reducing pressure at the vacuum end of the capillary and the temperature of the capillary are controlled to maintain motion of the moving interface away from the vacuum end of the capillary. Maintained movement of the interface prevents recoating of the stationary phase. A heating wire and capillaries are embedded in a thermally conductive polymer to create a highly responsive method of heating the multicapillary column. An electronic control device controls the feedback temperature of the multicapillary column using the heating wire.

Abstract: In a angular rate sensor, a weight and a base are connected directly through piezoelectric bimorph detectors and piezoelectric bimorph exciters each having a bent portion. When acceleration is applied to the weight, the weight is displaced so as to deform the piezoelectric bimorph detectors.

Due to this deformation, charges generated in the piezoelectric bimorph detectors are detected so as to detect the angular rate.
