Apparatus and method for detecting motion with low power consumption in inertia sensor |
摘要 |
A motion detector and method with low power consumption in an inertia sensor. The motion detector is selectively supplied with power for operation of the inertia sensor according to a power control signal. While the inertia sensor is supplied with power, three-dimensional analog signals are sampled, A/D converted, and outputted via a controller. A pulse width of the power control signal is determined by reflecting the sampling and A/D conversion period and reflecting the operation preparing period of the inertia sensor from the A/D converted value.
