We report about a fall-detection sensor system that detects the beginning of a fall. The fall-detection sensor system monitors the human pulse as a vital sign, acceleration, and angular velocity. The fall-detection algorithm using these signals enables us to detect the beginning of a fall correctly. Especially, the fall detection algorithm using the vital sign was able to distinguish between a case in which persons did not fall down due to keep their balance although the fall began and a case in which persons fell.
