  • Apparatus for detecting the rotation angle of a rotational body
    Patent number: 7073398
    Abstract: A rotation angle detection apparatus for reducing power consumption. A magnetoresistance element generates first and second analog signals, which change cyclically and continuously each time a steering shaft is rotated by 60 degrees. A microcomputer determines the rotation angle of the steering shaft from the output value and number of cycles of the analog signals.
