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.

Abstract: In a pedometer device (1), for detecting and counting steps of a user on foot, an accelerometer sensor (2) detects a vertical acceleration generated during the step. A processing unit (3) is connected to the accelerometer sensor (2), processes an acceleration signal (CalAcc) relating to the acceleration (A) in order to detect the occurrence of a step, and in particular compares the acceleration signal (CalAcc) with a first reference threshold (S + ). The processing unit (3) automatically adapts the first reference threshold (S + ) as a function of the acceleration signal (CalAcc). In particular, the processing unit (3) modifies the first reference threshold (S + ) as a function of an envelope (Env') of the amplitude of the acceleration signal.
