Abstract
A process for detecting activity of a person, in which movements of the person are measured by at least one sensor attached to the person, and respective components of the movements due to external activity and due to physiological activity are separated. The process obtains a signal of the sensor, filters the signal to derive a filtered signal, the filtering including partitioning the signal of the center into a low frequency component and high frequency component, and subtracts the filtered signal from the signal of the sensor. The filtering further variably extracts portions of the high frequency component according to a criterion of either a minimal level or a minimal instability of the signal of the sensor, and the filtered signal includes the low frequency component and the extracted portions of the high frequency components.
