A Short Message Service Based Design for a Portable Telealarm Device

Abstract

This paper presents an SMS based design in the GSM system for a portable, light weighted, and small sized TeleAlarm device. The device is composed of a transmitter and a controller. When an emergent situation such as a stroke or a fall occurs, the user only needs to push a button to trigger the controller. The controller automatically sends text messages stored in its database through the transmitter to specified mobile phone numbers for help. The SMS uses only the control channels in the GSM system to transfer the message, which enables the receiving-end user to receive it even during a call. An experimental test shows that a complete message transmission only needs 2.949 seconds in average. The design is convenient to elderly people who may live alone.

Design and Implementation of a Mobile-Care System over Wireless Sensor Network for Home Healthcare Applications

“…Under such situations, the required medical care or patient's condition monitoring must be provided through professional medical personnels so that the consumed manpower and social cost will be considerably high. In order to further reduce the waste of medical resources and achieve real-time care service, the concept of tele-care emerges by integrating the information and communication technologies [1], [2]. Therefore, it is an inevitable trend to create an appropriate home healthcare service by making use of tele-care.…”
