METHOD AND DEVICE FOR DETECTING ANOMALOUS EVENTS FOR AN ELECTRONIC APPARATUS, IN PARTICULAR A PORTABLE APPARATUS
First Claim
1. A method, comprising:
- generating at least one acceleration signal indicative of an acceleration acting on an electronic apparatus; and
detecting an anomalous event of the apparatus as a function of said acceleration signal, including;
monitoring a normal-mode condition of said electronic apparatus; and
detecting said anomalous event at least based on the exit of said electronic apparatus from said normal-mode condition.

Abstract
Detection of an anomalous event in an electronic apparatus includes detecting accelerations acting on the electronic apparatus, establishing a normal-mode range of accelerations that corresponds to normal operation of the apparatus, and detecting the anomalous event when a level of acceleration of the electronic apparatus exits the normal-mode range and remains outside the normal mode range for more than a defined duration. The method includes displacing the normal-mode range toward a current level of acceleration of the electronic apparatus while the level of acceleration remains outside the normal-mode range. Additionally, the normal-mode range is increased toward a maximum size while the level of acceleration remains outside the normal-mode range, and is decreased toward a minimum size while the level of acceleration is within the normal-mode range.
