摘要： A system includes at least one strip of ferromagnetic material and a plurality of pulsing/receiving coil circuits. The at least one strip of ferromagnetic material is induced with a bias magnetic field and is coupled to a surface of a structure under test. The plurality of pulsing/receiving coil circuits are aligned with a surface of the at least one strip of the ferromagnetic material. The plurality of pulsing/receiving coil circuits are individually controllable by a number of channels to excite guided waves in the structure under test using at least one of active phased-array focusing or synthetic phased-array focusing of the guided waves.

摘要： A gas detection system for the detection of gas voids in piping systems. The gas detection system includes a transmitter, a receiver, and a computer. The transmitter is positioned at a designated point on a piping circuit and is adapted to transmit guided waves into the piping circuit. The receiver is positioned at a designated point distant from the transmitter and is adapted to receive the guided waves transmitted through the piping circuit by the transmitter. The computer analyzes and monitors the guided waves received by the receiver and determines the amount of gas in the piping circuit being analyzed.
