Abstract: There is provided a method that includes (a) controlling a vibrator to produce an acoustic wave in accordance with a signal that includes (i) an on-time during which a packet of pulses is generated, followed by (ii) an off-time during which no pulses are generated, and thus includes (iii) a frequency component, (b) receiving an electrical representation of the acoustic wave that has been detected from a body of water that is being frozen on a structure, (c) extracting, from the electrical representation, (i) the frequency component, and (ii) a magnitude of the frequency component, (d) recognizing that the magnitude of the frequency component exceeds a threshold value, thus yielding a recognition, and (e) issuing a command to remove the body of water from the structure, in response to the recognition. There is also provided a system that employs the method, and a storage device containing instructions for the method.
