Elderly Health Care System of Systems by Non-Contacted Multiple Sensors

This paper describes a system of systems for elderly heath care. The system consists of three systems: one is the system that detects heart rate, which provides the condition of autonomous nerve system. The second one is the system detecting respiration. Third one is the system detectingthe sound to do suctiontreatment of phlegm. In them we emply non-contacted three senors. An ultrasonic oscillosensor touched to bed frame, an air pressure mat with an air tube in bed and PCM Recorder with microphone are employed. The system of systems can detect heart rate, respiration and sound to dosuctiontreatment of phlegm. This system assesses autonomous nerve system from the heart rate.
