INERTIAL MEASUREMENT SYSTEM WITH SMART POWER MODE MANAGEMENT AND CORRESPONDING SMART POWER MODE MANAGEMENT METHOD

An inertial measurement system (1), having: at least one motion sensor (2) to output motion data with an output data rate - ODR -period (T); and a control unit (4) coupled to the motion sensor (2) to control operation thereof based on a power mode switching, according to which each ODR period (T) envisages: a first phase (T), in which the motion sensor (2) is controlled in a condition of low power consumption; and a subsequent measurement phase (T), in which the motion sensor (2) is controlled to perform measurements for generation of measurement data. The control unit (4) adaptively adjusts the duration of the ODR period (T) based on at least one check related to the measurement data generated during the measurement phase.
