Abstract :
A mobile phone-based system has been developed to detect and transmit notification of elderly person daily-life emergency situations. The system employs a dual axis accelerometer, two low-power active filters, a low-power 8-bit single chip microcomputer, two mobile phones and a personal computer. The dual axis accelerometer measures body movements produced by respiration, posture changing, falling and activities. If the person´s respiration is paused for 3 minutes, or if they are in an inactive state for 1 minute after falling, or for 64 minutes without previously falling, then the system automatically sends the person´s location by e-mail. It also informs the patient´s family by voice, via the mobile phone, of the emergency situation.
