| 20110264384 | FLOW METER - A simple, passive and rugged device for measuring the flow rate of liquid. A variable area obstruction valve, a differential pressure sensor and a densitometer are combined in a single housing to provide for a highly accurate and precise measure of mass flow. | 10-27-2011 |
| 20110056285 | Focused field antenna for passive RFID tire pressure sensor transponder - A passive RFID transponder sensor system includes a sensor assembly having a focused field transponder antenna with a highly magnetically permeable transponder antenna stem, and a reader antenna with an electrical reader coil generating a magnetic field having magnetic flux extending between the reader antenna and a sensor assembly. The electrical transponder coil and the electrical reader coil are coupled by the magnetic field, so that information can be transferred to and from the sensor assembly through the magnetic field by which the electrical transponder coil and the electrical reader coil are coupled. | 03-10-2011 |
| 20090192667 | TIRE MONITORING SYSTEM - A plurality of pressure sensors are provided in a tire of an aircraft landing gear, such sensors being carried by the same stem assembly that has the inflation-deflation valve for the tire. A communication microcircuit is provided in the stem. The communication microcircuit is connected to one coil of a stem transformer, with the other coil of the stem transformer being electrically connected to one coil of an axle transformer. The other coil of the axle transformer is coupled to an axle communication circuit which powers the axle and stem circuits and polls the sensors to determine tire pressure. | 07-30-2009 |
