Title:
Leakage inspection equipment, programs, and control methods
Document Type and Number:
Japanese Patent JP6299597
Kind Code:
B2
Abstract:
A signal acquisition unit (2020) acquires a signal. From the signal acquired by the signal acquisition unit (2020), a detection signal extraction unit (2060) extracts, as a detection signal, a signal of any frequency band among a plurality of partial detection frequency bands into which the frequency band that is the subject of detection has been divided. A determination unit (2070) determines, in order, for each detection signal corresponding to each of the different partial detection frequency bands, whether the detection signal shows any leakage, and if at least a prescribed number of the detection signals are not showing any leakage, determines that leakage is not taking place.
