Abstract: For the purpose of gas quality monitoring, a spectroscopic examination of a gas sample from a space (10) to be monitored is carried out, e.g. by Raman spectroscopy. The spectroscopic examination yields a measurement spectrum extending over a wavelength range. A deviation of the measurement spectrum from at least one comparison sample (160) is then detected. Depending on the detected deviation, a gas quality warning (QW) is produced.

Abstract: An apparatus for automated maintenance of limited-access areas on large structures. The apparatus is a rolling or sliding tool-equipped mobile platform that is adhered to a surface by operation of one or more adherence fans and then propelled across the surface by operation of one or more propulsion fans. The adherence and propulsion fans are coupled to a base made of semi-rigid material. The adherence fans produce suction forces in one or more suction zones to adhere the mobile platform to the surface. The propulsion fans produce thrust to propel the surface-adhered mobile platform in a desired direction across the surface. The tool-equipped mobile platform is capable of adhering to and moving over a non-level surface on a large structure while keeping standoff contact elements in contact with the surface regardless of surface contour. The propulsion fans, adherence fans and maintenance tool (e.g., an NDI sensor unit) are controlled by a computer system.

Abstract: A method for imaging non-specular seismic events as well as correlating non-specular events with physically measurable quantites in a volume of Earth's subsurface. Includes entering as input to a computer signals detected by a plurality of seismic sensors disposed above and/or within the volume in response to actuation of at least one seismic energy source above and/or within the volume. Parameter analysis is performed to populate the initial model with point-wise, best-fit wavefront travel-time approximations. Imaging is performed to obtain undifferentiated specular and non-specular representations of the volume. Specular boundaries are mapped using the imaged volume and using the boundaries to form a model of specular components of the volume. Beamforming is used to characterize seismic attributes associated with specular and non-specular reflections as separate and differentiated data sets.
Abstract: Systems, methods, and apparatuses are provided herein that track an integrated deviation of a physical property of a material that corresponds to a variation or defect in the material. In one embodiment, molten steel begins to solidify and move past an instrumented region of a mold. Sensors in the mold can detect a deviation in temperature of the instrumented region of the mold that signifies a variation or defect in the surface of the slab material as it solidifies. The systems, methods, and apparatuses track the integrated temperature deviation to more clearly visualize defects that may otherwise not be detectable by simply observing the temperatures of the mold and slab material in real time.
