Abstract
A free-fall detector device includes an inertial sensor, a detection circuit associated to the inertial sensor, and a signal source for supplying a read signal to the inertial sensor. The device moreover includes: a storage element, selectively connectable to the detection circuit for storing a feedback signal generated by the detection circuit in response to the read signal supplied to the inertial sensor; and a feedback circuit coupled to the storage element for supplying the feedback signal to the inertial sensor so that the detection circuit generates at least one detection signal in response to the feedback signal supplied to the inertial sensor.
