20080236282 | System and method for detection of freefall with spin using two tri-axis accelerometers - 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. | 10-02-2008 |
