    • An electronic device is operated based on whether it detects vibration indicative of natural human tremors while the device is not enclosed in a small space. Human tremors are detected by sampling a motion signal and performing a discrete Fourier transformation on a plurality of sets of samples. For each sample, a mean magnitude is calculated for a first range of frequencies indicative of human tremors. A mean magnitude is also calculated for a second range of frequencies greater than the first range. If the difference between the mean magnitude of the first range and the mean magnitude of the second range, then human tremors are detected for the set of samples. Human tremors are detected for the device if a threshold number of sets of samples within a predetermined time period produce an output indicating detection.
    • 一种电子设备,是基于是否检测指示自然人类震颤振动,同时该装置没有在小空间封闭操作。 人类震颤由采样的运动信号并执行上的样本集的多个离散傅立叶变换来检测。 对于每个样品,平均幅度计算用于指示人的抖动频率的第一范围。 因此,一个平均幅度计算频率比所述第一范围大的第二范围。 如果第一范围的平均幅度和所述第二范围的平均大小之间的差异,针对所述一组样品的检测到的人类然后震颤。 该设备被检测到的人如果震颤的预定TIMEPERIOD内样本集的阈值数目产生在输出指示检测。
