ABSTRACT:
A method and apparatus for detecting the position of a movable device are provided, in which an acceleration signal of the movable device is obtained and the acceleration signal is converted to a digital signal using an acceleration sensor; a high level time of the digital signal is counted, based on a predetermined frequency; the absolute displacement of the movable device is calculated by integrating the counted high level time of the digital signal twice; and the absolute displacement is converted to a binary gray code and the binary gray code is output.
