Hard Disk Drive Protection System Based on Adaptive Thresholding

Abstract

A method and apparatus for detecting unusual motions of an electronic device is disclosed. One example method includes measuring motion values of a device and comparing at least one motion value to a threshold to detect an unusual motion. The threshold is regularly adjusted based on at least a portion of the motion values. Another example method is directed to detecting an unusual motion of an electronic device based on motion values measured over a period of time. A plurality of motion values may be measured over a period of time and a cumulative function of the values may be compared to a threshold. A variety of protective actions or measures may be taken to protect a hard disk drive and/or other components in the electronic device from damage when unusual motions are detected.
