Activity monitoring and emergency warning with location information of the user

Recent advances in communications technologies and embedded systems have allowed the development of remote health monitoring systems. There are different approaches depending on the available measurements and the communication system used. In this paper an activity monitoring system is proposed in order to detect falls and/or faints of the user. The feature that distinguishes this system from other activity monitoring systems is the ability of auto-localization in both outdoor and indoor environments as well as the ability to automatically generate alarms to alert the medical personnel if there is any emergency situation.
