摘要： A new ultrasonic method for measuring wall thickness and detecting material flaws in natural-gas pipelines, risers, and similar structures. The method is inherently suitable for the task, because it relies on the use of the natural gas as the coupling fluid for transmitting the probing ultrasonic signals into and out of the pipe wall. Furthermore, the method facilitates the operation of the inspection from the inside of the pipe. An experimental apparatus used to demonstrate the technical feasibility of this approach and provide experimental and theoretical evidence that support the claims is described. Significantly, it is shown that by the use of a diplexer, the same transducer can be used to generate and detect the probing ultrasonic signals. The same configuration is used in commercial ultrasonic inspection of oil pipelines where oil is the coupling fluid; but until now this method could not be used in natural gas pipelines due to the low specific acoustic impedance of natural gas.

摘要： Systems and methods for flaw detection and monitoring at elevated temperatures with wireless communication using surface embedded, monolithically integrated, thin-film, magnetically actuated sensors, and methods for fabricating the sensors. The sensor is a monolithically integrated, multi-layered (nano-composite), thin-film sensor structure that incorporates a thin-film, multi-layer magnetostrictive element, a thin-film electrically insulating or dielectric layer, and a thin-film activating layer such as a planar coil. The method for manufacturing the multi-layered, thin-film sensor structure as described above, utilizes a variety of factors that allow for optimization of sensor characteristics for application to specific structures and in specific environments. The system and method integrating the multi-layered, thin-film sensor structure as described above, further utilizes wireless connectivity to the sensor to allow the sensor to be mounted on moving components within the monitored assembly.

摘要： The system and method provides means for detecting fiber optic cable embedded within a structure such as a wall of a building. It relies upon detecting an electrical field generated by movement of static and induced electrical charged fiber optic cable contained within the building wall. The invention is particularly useful when only one side of a wall structure is accessible and there is no access to the fiber optic cable. The process comprises the steps of locating wall studs, making a small hole in the wall material between the wall studs at approximately mid height, inserting a field emitter in the small hole for generating an electrical charge on a fiber cable, inserting an air nozzle in the small hole to create fiber cable movement, and detecting an electric field generated by the movement of an electrically charged fiber cable.

摘要： A method and apparatus is shown for implementing magnetostrictive sensor techniques for the nondestructive short term inspection or long term monitoring of a structure. A plurality of magnetostrictive sensors are arranged in parallel on the structure and includes (a) a thin ferromagnetic strip that has residual magnetization, (b) that is coupled to the structure with a couplant, and (c) a coil located adjacent the thin ferromagnetic strip. By a transmitting coil, guided waves are generated in a transmitting strip and coupled to the structure and propagate along the length of the structure. For detection, the reflected guided waves in the structure are coupled to a receiving strip and are detected by a receiving magnetostrictive coil. Reflected guided waves may represent defects in the structure.

摘要： An apparatus and method for optimizing computer tomography images obtained from any of a number of different standard computer tomography scanning devices. The apparatus and method incorporate computer-aided design data for an object being scanned into a system for establishing nominal scanning beam intensities and nominal scanning detector sensitivities that ultimately compensate for non-anomalous variations in beam path characteristics. Particularly adapted for optimizing scan images on objects with large length-to-width ratios, the present invention identifies significant deviations from some normal baseline beam path in advance of a scan and modifies beam intensity and detector sensitivity to bring the projected beam into a nominal range. Thereafter, deviations from this referenced nominal beam can be better identified as anomalies within the object being scanned, that are of interest.

摘要： A non contact sensor for use in magnetostrictive testing of a solid ferrous structure. In its simplest form, the sensor has a set of permanent magnets arranged in a row with their poles in the same direction, an electrical coil wrapped around the set of magnets, wrapped in direction parallel to the common poles of the magnets, thereby forming a top portion above the set of magnets and a bottom portion below the set of magnets, and a metal shield interposed between the top portion of the coil and the set of magnets. The sensor is operable such that a time varying current in the coil causes guided waves to travel to the structure and to be reflected from anomalies in the structure even when there is no ferromagnetic coupling material between the sensor and the structure.
