    摘要: A rotation sensor includes a binary encoded target wheel (10) and a pair of sensors (20,30) disposed about the target wheel periphery. One of the sensors (20) provides a signal (V out1 ) indicative of the passage of regular angular intervals (60-63) of the target wheel (10) and the other of the sensors (30) provides binary states (V out2 ) corresponding to the regular angular intervals (60-63).

    摘要: A method and apparatus for detecting an engine crankshaft angular position which provides for fast starting of the engine. A target wheel (10) and sensor (24 and 26) combination generate an analog signal which is converted into a 24 bit digital output which repeats every 360° rotation of the crankshaft. Each bit represents a particular angular position of the crankshaft. Any 6 sequential bits in the repeating 24 bit digital output sequence form a unique pattern. By monitoring the first six bits generated (90° of crankshaft rotation) during start-up, a crankshaft angular position can be determined, thereby enabling fast starting of the engine.
