Analyzing an acoustic wave that has propagated through a body of water while the body of water is being frozen

摘要

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.
