Abstract: Described herein is a method for detecting an anomalous event, like a crash or a free fall, in an electronic apparatus (1) , which envisages the steps of: detecting at least one acceleration signal (Acc) indicative of an acceleration acting on the electronic apparatus (1); and detecting the anomalous event as a function of the acceleration signal (Acc). The step of detecting the anomalous event envisages the steps of: monitoring a normal-mode condition of the electronic apparatus (1); and detecting the anomalous event at least based on the exit of the electronic apparatus (1) from the normal-mode condition. In particular, the step of monitoring a normal-mode condition envisages the steps of: determining a change or variation of acceleration (”Acc) associated to the acceleration signal (Acc) ; executing a comparison between the variation of acceleration (”Acc) and an acceleration threshold (THA); and determining the permanence in, or exit from, the normal-mode condition according to the result of the comparison. Also described is a detection device (6) implementing the above method.

Abstract: Described herein is a sensor device (2) for an electronic apparatus (1), provided with: a sensing structure (5) generating a first detection signal (A x ); and a dedicated integrated circuit (6), connected to the sensing structure (5), detecting, as a function of the first detection signal (A x ), a first event associated to the electronic apparatus (1) and generating a first interrupt signal (INT1x) upon detection of the first event. The dedicated integrated circuit (6) detects the first event as a function of a temporal evolution of the first detection signal (A x ), and in particular as a function of values assumed by the first detection signal (A x ) within one or more successive time windows (T s1 -T s3 ), and of a relation between these values.

Abstract: In an integrated free-fall detection device (16) for a portable apparatus (10), an acceleration sensor (20) generates acceleration signals (A x , A y , A z ) correlated to the components of the acceleration of the portable apparatus along three detection axes (x, y, z). A dedicated purely hardware circuit (24), connected to the acceleration sensor (20), generates in a continuous way and in real-time a free-fall detection signal (F). The free-fall detection signal (F) has a first logic value in the event that the acceleration signals (A x , A y , A z ) are simultaneously lower than a respective acceleration threshold (A th ), and is sent to a processor unit (18) of the portable apparatus (10) as an interrupt signal to activate appropriate actions of protection for the portable apparatus (10). The acceleration sensor (20) and the dedicated purely hardware circuit (24) are integrated in a single chip, and the acceleration sensor (20) is made as a MEMS.
