METHOD AND DEVICE FOR SYNCHRONIZING DATA PACKETS FROM EMBEDDED DATA SENSORS MONITORING BODY MOTION OF A PATIENT

Method for synchronizing data packets from embedded wireless data sensors for monitoring body motion of a patient, wherein each said sensor has an independent time base for applying timestamps to data packets sent from each said sensor; said method comprising the steps of: receiving an initial data packet having a timestamp from a first sensor; storing the timestamp of the initial data packet from the first sensor, herewith defined as reference timestamp; for each received data packet having a timestamp from said sensors, received subsequently to said initial data packet, for the first sensor, storing the timestamp of the most recent data packet from said first sensor, herewith defined as reference timestamp; for the sensors other than the first sensor, calculating the difference between the timestamp of a received data packet and the reference timestamp; calculating an average of said differences for the received data packets for each said sensor; correcting the timestamp of the received data packet with the calculated average of said differences of the respective sensor; using the corrected timestamps of the received data packets to synchronize the data packets from the embedded wireless data sensors.
