Claim 7:
8. The method of claim 7, wherein the ultrasonic signals include a frequency-modulated continuous wave (FMCW) ultrasonic signal having a first portion that increases in frequency in a frequency range and a second portion that decreases in frequency in the frequency range, further comprising:
identifying, from the group of the energy values and in a first time frame, a first energy value that corresponds to the first portion, the first energy value being associated with a first distance;
identifying, from the group of the energy values and in a second time frame adjacent the first time frame, a second energy value that corresponds to the second portion, the second point being associated with a second distance; and
calculating an average distance using the first distance and the second distance,
wherein determining the distance data is based at least in part on the average distance.
