The Study of Mobile Tele-Care on PSTN The tele-care system is designed to help vulnerable chronically ill people of living in their own homes for indoor and outdoor occasions. Tumbling signals and physiological signals of the patient can be transmitted by wireless sensor via Bluetooth Transceiver to PMG then relays to remote Medical Server. If it is nessary, the voice dialog can be proceeded through PSTN. Trained medical personnels are alerted to respond emergency conition. These chronically ill people now can get e help, 24 hours a day all round year. Figure 1. shows software algorithm of portable pulsimeter which samples every 0.05 second, when pulse beats then it records , otherwise it does not record. We design this pulsimeter sending pulse of record every 60 seconds via Bluetooth SPP Profile to PMG.
