Field: Telecommunications (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 22:
23. The device for timestamping and synchronization with high-accuracy timestamps in low-power sensor systems as claimed in claim 13, wherein the sensor hub and the latch further executes:
obtaining, by the sensor hub, a system time from the sensor through a controller;
obtaining, by the latch, a first time from the time of the always-running unified time reference when the controller finds a time synchronization protocol;
obtaining, by the sensor hub, a time offset by using a filtering algorithm according to the system time and the first time transmitted from the latch; and
writing, by the sensor hub, the time offset to the sensor for time synchronization between the sensor hub and the sensor through the controller;
wherein the system time is based on a time reference that is different from the always-running unified time reference.
