摘要: An energy-efficient acceleration measurement system is presented. The includes an accelerometer, responsive to of the system, for providing accelerometer output signal having a magnitude indicative at least one component acceleration. A motion detector signal, and provides processor interrupt but only if reaches threshold. processor, measures with higher accuracy than capable of, in way that consumes more power was needed by detector.
