摘要： Method and apparatus for actively protecting a device from damage due to an impact or other acceleration condition. An active protection system is provided with a sensor which outputs an acceleration signal in relation to an acceleration state of the device. A circuit processes the acceleration signal in relation to a configuration control input indicative of an operational environment in which the device is operated, and a protection mechanism configures the device in relation to the processed acceleration signal. A configuration control module preferably supplies the configuration control input as a user selectable or host input. Preferably, protection mechanism places the device in a protective state to protect against damage due to an imminent impact, such as from a free fall condition. The processing preferably comprises adaptive filtering of the acceleration signal and the application of one or more thresholds to detect said imminent impact.
