Abstract
A method that includes: (i) detecting an acoustic wave that is propagating through a body of water, as the body of water is being frozen on a structure, thus yielding a detected acoustic wave; (ii) extracting, from the detected acoustic wave, (a) a frequency component thereof, and (b) a magnitude of the frequency component; and (iii) removing the body of water from the structure when the magnitude exceeds a threshold value.
