Design and implementation of a mobile distributed heartbeat monitoring system based on Bluetooth

Abstract

The goal of this master thesis is to develop a mobile, distributed monitoring system for outdoor cardiovascular training, based on Bluetooth sensors, mobile handsets with Java Micro Edition (Java ME) and XML Web Services technologies. A Java ME MIDlet will be specified, implemented and tested, which communicates with a heart rate sensor and a GPS module using a wireless Bluetooth link. The MIDlet will display the pulses received from the sensor, with the duration of training and a graph that shows the instantaneous course of training. The GPS module is used for geographical positioning, velocity measurements and recording of the altitude profile for the duration of the exercise.The results from the sensors will be recorded both in a local database on the handset as well as on a server, whereto the results are transmitted using XML Web Services technologies. The system will also include a Web-based interface for accessing the stored information about previous exercise sets.
