End-to-End Signal Processingfrom the Embedded Body Sensor to theMedical End User Through QoS-LessPublic Communication Channels: The U-R-SAFE Experience

摘要

The URSafe project (IST-2001 -33352) aims at creating a leiemedicine 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 medicai 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.
