| 7284452 | Cantilever sensor using both the longitudinal and the transversal piezoresistive coefficients The present invention relates to a sensor comprising least one sensor unit e.g. a cantilever. The sensor unit comprises a capture surface area and a piezoresistive detection system, for direct detection of stress change of the sensor unit when applying an electrical... | 10/23/2007 |
| 7275417 | Fueling system vapor recovery and containment performance monitor and method of operation thereof A method and apparatus for monitoring and determining fuel vapor recovery performance is disclosed. The dispensing of liquid fuel into a tank by a conventional gas pump nozzle naturally displaces a mixture of air and fuel ullage vapor in the tank. These displaced va... | 10/02/2007 |
| 6968868 | Fueling system vapor recovery and containment performance monitor and method of operation thereof A method and apparatus for monitoring and determining fuel vapor recovery performance. The dispensing of liquid fuel into a tank by a gas pump nozzle displaces a mixture of air and fuel ullage vapor in the tank. These displaced vapors may be recovered at the dispens... | 11/29/2005 |
