Abstract: A high-precision corrosion monitoring sensor assembly is provided for permanent mounting on a vessel to measure wall thickness of the vessel. The assembly includes an ultrasonic transducer and a delay line, which are bonded to the vessel wall a first location. The assembly is further bonded to the vessel by an adjustable fixture. The assembly includes a cross-member attached to the ultrasonic transducer, having a pivot pin at each distal end. The pivot pins are attached to a first tower and a second tower, which bond to the outer vessel wall at a second location and a third location. The position of the first and second towers can be adjusted with respect to angle and placement about the pivot pins. Fasteners are attached to the pivot pins and can be tightened to make rigid the fixture, thereby allowing configuration of the assembly for use on flat surfaces and small-diameter pipes.

Abstract: 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.

Abstract: 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.
