Method for synchronizing timestamps from embedded wireless data sensors
A recently granted patent (Publication Number: US11917567B2) outlines a method for synchronizing data packets from embedded wireless data sensors used to monitor body motion in patients. The method involves receiving initial data packets with timestamps from sensors, storing reference timestamps, calculating differences between subsequent timestamps, and correcting timestamps based on averages of these differences. By using corrected timestamps, the data packets from various sensors are synchronized to ensure a lower timestamp difference, meeting a predetermined accepted maximum. The method also includes steps for handling missing data packets, constructing interpolated data packets, and discarding erroneous data packets to maintain synchronization effectively.
Furthermore, the patent describes a device equipped with an electronic data processor to implement the synchronization method. The device receives data packets, calculates timestamp differences, and corrects timestamps to synchronize data from multiple sensors. It also includes features for repeating calculations for a specified time duration, outputting periodic data packet sets, and constructing interpolated data packets for missing data. The device ensures that the timestamps of received data packets are corrected to maintain synchronization within the predetermined accepted maximum timestamp difference. Overall, the patented method and device offer a comprehensive solution for synchronizing data packets from embedded wireless data sensors, particularly in monitoring body motion in patients, ensuring accurate and reliable data processing.
