20090130868 | SOLENOID AND CONNECTOR ASSEMBLY - The present invention provides a solenoid and electrical connector assembly which includes a solenoid body having a pair of electrical terminals disposed on opposite sides of a plunger component and a connector having two corresponding electrical terminals and a non-conductive blade or tongue disposed therebetween. When assembled, the tongue of the connector seats between the terminals on the solenoid body and inhibits corrosion and ingress of foreign matter in the region between the terminals of the solenoid. | 05-21-2009 |
20090259381 | System for Monitoring Engine Performance of an Engine Via Torque Converter Operating Information - Determining performance of an internal combustion engine coupled to a pump of a torque converter may include determining a rotational speed of the pump, determining a rotational speed of a turbine fluidly coupled to the pump, determining an engine output torque value, corresponding to torque applied by the engine to the pump of the torque converter, as a function of the rotational speed of the pump and the rotational speed of the turbine, and storing the engine output torque value in a memory unit. Alternatively or additionally, engine horsepower may be determined as a function of the engine torque and/or a fuel efficiency of the engine may be determined as a function of the horsepower and fueling rate of the engine. The engine output torque value, horsepower value and/or fuel efficiency may be stored in a memory unit and/or displayed on a display unit. | 10-15-2009 |

20090281698 | SYSTEM AND METHOD FOR CONTROLLING SOLENOID PRESSURE - A method for calibrating an input electrical signal to an individual pressure control device includes the steps of providing a target pressure-to-current (P/I) threshold, providing a lower estimated P/I threshold, and providing an estimated P/I curve that passes between the target P/I threshold and the lower estimated P/I threshold. Next, the method determines a lower actual P/I threshold at a pressure equal to the pressure at the lower estimated P/I threshold. A maximum offset current is calculated from the difference between the currents at the lower actual P/I threshold and the lower estimated P/I threshold. Finally, the method calculates a calibrated P/I curve. The calibrated P/I curve includes the target P/I threshold and the lower actual P/I threshold. The slope of the calibrated P/I curve is calculated as a proportional value of the maximum offset current. | 11-12-2009 |
