摘要： An apparatus includes a reflector, a microphone coupled to the reflector, laser emitters coupled to the reflector, and a laser range finder coupled to the reflector. The laser range finder is configured to output a signal indicative of a distance between the reflector and an object. The apparatus adjusts a position and/or a power level of the laser emitters based on the distance between the reflector and the object. Additionally or alternatively, the apparatus adjusts a position and/or a power level of the laser emitters based on a type of sound waves. Laser beams of light emitted by the laser emitters visually indicate a region in which a source of detected sound waves is located.

摘要： Disclosed herein are various implementations of systems and methods for improving the process and accuracy of converting acoustical signals to leak rates through a structure, such as a closed valve or coupling, using filtering techniques and modal analysis. These systems and methods may be useful for verifying the accuracy of the conventional approaches and inventive processes and systems for improving leak rate quantification using acoustic emissions. For example, a testing apparatus for simulating a leak through a structure and methods for correlating an acoustical signal with a leak rate are disclosed. The information gathered from the testing apparatus and/or correlation methods may be used in the field to determine more accurately the leak rate of a fluid or gas through the structure.

摘要： The present invention reduces production costs associated with a device that uses results of detection by a plurality of vibration detectors to detect a leakage position in a pipe.A first time difference calculation unit 114 calculates a time difference Δt1 between the timing of detection of vibration that indicates the first vibration mode of a pipe P and the timing of detection of vibration that indicates a second vibration mode of the pipe P by processing a result of a measurement made by a first vibration detection unit 112. A second time difference calculation unit 124 calculates a time difference Δt2 between the timing of detection of vibration that indicates the first vibration mode of the pipe P and the timing of detection of vibration that indicates the second vibration mode of the pipe P by processing a result of a measurement made by a second vibration detection unit 122. A leakage position calculation unit 130 uses the time differences Δt1, Δt2, and a space interval I between the first vibration detection unit 112 and the first time difference calculation unit 114 to calculate a leakage position in the pipe P.
