Abstract: A system and method detect freefall associated with an object that is spinning or tumbling as it falls. Two tri-axis accelerometers provide inputs to an algorithm that detects the freefall of a spinning object that would not otherwise be detected by a conventional freefall detection system, due to the centrifugal and centripetal forces being placed on the falling object as it spins. The system can be used to detect the freefall of portable devices with onboard memory or hard disk drives, allowing the devices to have time to park the read/write head and reduce the potential of losing data that can be damaged by impact. This freefall detection system may be applied to such portable devices as notebook computers, PDAs, MP3 players, digital cameras, mobile phones and even automobiles.

A motion of the portable terminal is input by measuring an acceleration along the X-, Y- and Z-axes of the portable terminal. A current posture of the portable terminal is calculated by calculating rotation angles along the X- and Z-axes with respect to the X- and Z-axes in a basic posture using the acceleration along the X-, Y- and Z-axes. The acceleration along each axis is converted to an equivalent basic-posture acceleration along each axis using the rotation angles. The detected motion of the portable terminal is recognized using the basic-posture acceleration along each axis.
