CLOSURE DETECTION SYSTEM

A system and method for verifying a connection between a first and second connector. The system includes a transducer and a processor. The processor is configured to determine a velocity of the first connector when the first connector is moved to the second connector to form a coupling, calculate a time interval to the coupling based on the velocity detected at the set point and a position of the second connector, and receive, from the transducer, a signal during the time interval. The signal includes the sound generated when the coupling is formed. The processor analyzes the signal and identifies the sound of the coupling within the signal. The signal is filtered in the frequency domain and in the time domain, resulting in a filtered spectrogram. The spectrogram is compared to a pattern. The processor determines if the first and second connector are properly coupled based on the comparison.
