End-to-end signal processing from the embedded body sensor to the medical end user through QoS-less public communication channels: the U-R-SAFE experience.

ABSTRACT

The URSafe project (IST-2001-33352) aims at creating a telemedicine care environment for the elderly and convalescent. The idea is to provide a portable device which monitors autonomously different biomedical signals and is able to send an alarm to a medical center if an abnormality is detected. In the initial version of URSafe, three sensors where included in the platform electrocardiogram (ECG), oxygen rate (SpO2) and Fall Detector. This paper presents the signal processing algorithms involved in the project. These are at two levels ECG analysis and signal transmission.
