Title:
人の転倒を検出するための方法及びシステム
Document Type and Number:
Japanese Patent JP5184761
Kind Code:
B2
Abstract:
The method involves placing a sensor, comprising an accelerometer (31) and a magnetometer (41), on a person. An acceleration signal and an ambient magnetic-field signal provided by the sensor are continuously monitored. The fall of the person is indicated when a set of criteria is observed. The criteria include a period of instability in the acceleration signal, followed by stability in the acceleration signal, and a gradual variation in the magnetic-field signal during the instability period, between two different levels of the magnetic-field signal measured before and after the period. An independent claim is also included for a system for detecting the fall of a person.
