Development of the detection and reporting device for patients驴 getting out of bed using ultrasonic radar and power line communication

摘要

We propose the detection and reporting device for confirming the safety of the patients at small nursing facilities or ordinary houses. The device combines the ultrasonic sensor which detects patients驴 getting out of bed with power line communication (PLC) as a reporting system. The ultrasonic sensor in this device detects elderly person驴s getting out of bed and lying down to bed. The effectiveness of the proposed device has been confirmed by the field experiments in welfare facilities for elderly people.
