摘要:
A fall detection device includes a fall detection circuit to detect a fall by a user and a verification circuit to verify the initial indication of a fall from the fall detection circuit. The device is sized to be worn by the user and includes an orientation sensor to track the orientation of the device relative to one or more axes. The device averages the average inclination values for one or more axes for time periods before, during, and after the fall. A fall is determined to have occurred when differences in the average values of the inclination values exceed threshold values.
