Conference Proceeding: Fuzzy Detection System of Behavior before Getting Out of Bed by Air Pressure and Ultrasonic Sensors[show abstract] [hide abstract]
ABSTRACT: In this paper, we introduce a health monitoring system by both air pressure and ultrasonic sensors. The system of these sensors can complementary detect a behavior before getting out of bed with high accuracy aided by fuzzy membership functions. In this system, the ultrasonic sensor can obtain vibration information of human by setting it the under a bed frame. The air pressure sensor can also detect a pressure change of movement of human by setting it into the mattress on the bed. By using these sensors, we construct a fuzzy system to detect a behavior before getting out of bed.Granular Computing, 2007. GRC 2007. IEEE International Conference on; 12/2007
