Original Abstract Submitted
Methods and corresponding systems and apparatuses for time-aligning a first set of measurement samples captured by a first sensor to a second set of measurement samples captured by a second sensor. Each sensor captures samples at regular intervals corresponding to a respective sampling period. The sensors directly or indirectly measure at least one reference signal. Each reference signal includes a reference marker followed by a sequence of alignment pulses. In the case of multiple reference signals, the sequence of alignment pulses can differ, but the reference marker can be identical. In some implementations, time-alignment involves assigning a timestamp to a first alignment pulse in the first set of measurement samples, relative to the reference marker in the first set of measurement samples and assigning a second timestamp to a second alignment pulse in the second set of measurement samples, relative to the reference marker in the second set of measurement samples.
