Abstract: A method and system for determining the inclination of the suspended portion of a moving vehicle with respect to the road from a 2 axis or 3 axis accelerometer, inclinometer, or the like, for use in controlling a system or device that is dependent upon inclination. The method and system provide for the determination of the angle of inclination of the portion of the vehicle which is suspended with respect to the portion of the vehicle which is not suspended. The angle of inclination is derived from the dependence of acceleration along the axis normal to the vehicle (z axis) due to longitudinal (x axis) and/or latitudinal (y axis) accelerations of the vehicle.

Abstract: Systems and methods to detect when the external magnetic field becomes higher than the saturation field of AMR material are described. Approaches include saturation detection by combining sensors with different full-scale ranges, saturation detection using DC current and saturation detection by arranging sensitive axes at 45° offsets.
