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： A control system coupled to a pressure sensor calibrates the pressure sensor. The control system may measure a plurality of capacitance values at a plurality of corresponding applied voltages to compare the values with a first calibration mechanism generated by sample pressure sensors in a comparison. A final calibration mechanism may be generated by adjusting the first calibration mechanism in response to the comparison. The unknown differential pressure may be applied to a diaphragm of the pressure sensor. A capacitance value at the unknown differential pressure may then be measured. Using the final calibration mechanism, the differential pressure at the measured capacitance value may be retrieved.

摘要： A valve structure having a top part, a flexible media conveyance, such as a tube, a diaphragm and a bottom part with a support for the tube. The top surface of the diaphragm and the bottom surface of the top part may have electrodes attached. When there is no electric potential applied across the electrodes, the diaphragm may rest on and close the passageway in the flexible tube for effectively preventing a fluid flow. When an electrical potential is applied to the electrodes, the diaphragm may be pulled up off from the tube thereby opening or partially opening the passageway in the tube for a media flow or pressure transfer. Partial opening may be for modulation purposes. There may be a tension mechanism attached to the diaphragm. A controller may apply an electrical potential to the electrodes for at least partially opening or closing the valve.

摘要： A valve for regulating the flow of fluids (gas or liquid) using two flexible diaphragms in which an additional element is added to promote rolling contact between the diaphragms. The valve operates in a normally open configuration where fluid flows into the valve, passed through holes or openings in two electrostatically operative diaphragms and out of the valve. The holes or openings in one diaphragm are offset from the holes or openings in the other diaphragm, so that upon electro-static actuation, the diaphragms will seal together, closing the valve.

摘要： A device for sensing pressure including a chamber defining part having a first diaphragm mounted in communication with the sealed chamber defining part, and a second diaphragm electrically insulated from the first, preferably by a spacer. The diaphragms are flexible and have a conductive surface. A sensor chamber is mounted on the other side of the second diaphragm. It has an opening in communication with a sensing atmosphere. One of the diaphragms includes openings it its surface to permit fluid to flow through the openings and the other diaphragm is solid and responds to change in pressure in the sensor chamber to move away from or toward the one diaphragm. Electrical connections measure the capacitance between the diaphragms as a function of the pressure in the sensor chamber.

摘要： A device for sensing pressure using two flexible diaphragms in which an additional element is added to promote rolling contact of the diaphragm. One embodiment aligns the flexible diaphragms in a non-parallel alignment such that deflection of one flexible diaphragm will roll with respect to the other to provide increased linear capacitive response. In another embodiment a non-conductive spacing element is positioned between the diaphragms to permit rolling contact upon displacement of a diaphragms. These devices are capacitive pressure gauges. One additional embodiment includes a cantilever hinge and rigid polymer disc to convert one diaphragm into a linearly deflecting diaphragm.

摘要： An asymmetric micro pump may be adapted to provide a greater fluid compression between input and output ports of the micro pump, as well as increased flow rate due to higher actuation frequency. In some instances, asymmetric dual diaphragm micro pumps may be combined into assemblies to provide increased pressure build, improved pumping volume, or both, as desired.

摘要： A pressure sensor having a predetermined chamber dome angle with an electrode. A hole is located in the top to provide pressure readings and the bottom has an input port. A primary diaphragm is coated on both sides with an electrode and an insulator. A secondary diaphragm is coated on the side which faces the primary diaphragm. Offset holes are made in the two diaphragms which permits pressure equalization during self calibration. Both diaphragms are initially energized to seal the gage volume, and then the secondary diaphragm is used to self calibrate using a known pressure.

摘要： A device for sensing pressure using two perforated rigid films in which a diaphragm is mounted between the first two films. The device senses positive and negative pressure through a port or opening to the region for which pressure data is desired. The device communicates capacitive pressure and changes in that pressure. The flexible diaphragm is spaced from the first and second films such that the flexible diaphragm is adapted to flex toward the first film when pressure increases in the opening and is adapted to flex toward the second film when pressure decreases in the opening to change the capacitance between the diaphragm and at least one of the first and second films. Spacers are used to position all three elements.
