An automated abnormal-signal segregation and extraction technique based on inverse filtered acoustic/vibration signals proved effective for monitoring abnormal conditions in rotary machines, compressors, piping and high-pressure vessels. An intelligent sensor system detected leakage of high-pressure gases in oil refineries using pattern recognition techniques.}, number={2}, journal={Canadian Acoustics}, author={Ohba, Ryoji and Tamanoi, Yoshihito and Kuwahara, Toshiyuki and Edanami, Kozo}, year={2002}, month={Jun.}, pages={30–32} }
