Claim 1:
2. The monitoring device of claim 1, the average distance being a first average distance, the operations further comprising:
identifying, for a third time frame, a third energy value that corresponds to a third reflection of a first portion of a second FMCW ultrasonic signal, the third energy value being associated with a third distance;
identifying, for a fourth time frame adjacent the third time frame, a fourth energy value that corresponds to a fourth reflection of a second portion of the second FMCW ultrasonic signal, the fourth energy value being associated with a fourth distance;
calculating a second average distance using the third distance and the fourth distance; and
determining, using the first average distance and the second average distance, multiple distances between the object and the monitoring device during the period of time.
