摘要： A system for determining an absolute position of a motor. The system includes first and second multi-polar magnetic rings, first and second processing units, and at least one external sensor. The first multi-polar magnetic ring is concentrically positioned around the motor, and has a plurality of pole pairs. The second multi-polar magnetic ring is concentrically positioned around the first multi-polar magnetic ring, and has at least one pole pair. The first processing unit is positioned near the first multi-polar magnetic ring to determine an angular position over one of the pole pairs of the first multi-polar magnetic ring. The sensor is positioned external to the processing unit and over the second multi-polar magnetic ring to indicate a state of the pole pair of the second multi-polar magnetic ring. The second processing unit generates an absolute position of the motor based on the angular position and the state.

摘要： A device for sensing the input shaft speed of an automotive automatic transmission that is driven by the engine through the fluid coupling of a torque converter. The speed sensor device includes circumferentially spaced markings about the transmission input shaft and a speed sensor that is placed at close proximity to the circumferentially spaced markings through a hole in the torque converter stator shaft. An electronic control unit (ECU) analyzes the sensor output signal and in the case of an active speed sensor it also functions as its power source. During vehicle operation, the transmission input shaft rotates the target wheel in front of the speed sensor causing modulation of its output signal. The electronic control unit analyzes the signal modulation and calculates the input shaft rotational speed. A variety of sensor/target-wheel options and sensor mounting techniques could be used depending on the application constraints.
