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 (ΔAcc) associated to the acceleration signal (Acc) ; executing a comparison between the variation of acceleration (ΔAcc) 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.
