摘要： A display is provided. The display device includes a display area and a non-display area located around the display area; a base layer; an organic light-emitting diode (OLED) that is located on the base layer in the display area; and a first crack detection line that is located on the base layer in the non-display area; wherein the first crack detection line comprises a first line that extends substantially in a first direction along a first edge of the display area, a second line that is separated from the first line and extends substantially in the first direction, and a third line that is connected to an end of the first line and an end of the second line, wherein a cross-sectional shape of the first line in a second direction crossing the first direction is inversely tapered.

摘要： An exemplary method of indicating a condition of grout within a post-tensioned tendon involves positioning a magnet and a metallic sensing plate in close proximity to an outer surface of the post-tensioned tendon; rotating the magnet and the metallic sensing plate around the outer surface of the post-tensioned tendon; measuring an amount of magnetic forces applied to the magnet during rotation of the magnet around the post-tensioned tendon; measuring an impedance between the metallic sensing plate and metallic strands within the post-tensioned tendon during rotation of the metallic sensing plate around the post-tensioned tendon; and generating an image of a cross-section of the post-tensioned tendon indicating one or more grout conditions in spatial proximity to the metallic strands within the post-tensioned tendon based on measurement data using the magnet and the metallic sensing plate.

摘要： A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, each tension member including a plurality of fibers. A metallized coating layer is applied to at least a portion of an outer surface of at least one tension member of the plurality of tension members. The metallized coating has a coating electrical conductivity greater than a tension member electrical conductivity of the at least one tension member. A jacket material at least partially encapsulates the plurality of tension members and the metallized coating layer.

摘要： A composition comprising: (i) an electrically non-conductive fiber having a surface; and (ii) piezoelectric particles adhered to the surface of said electrically non-conductive fiber, and optionally, (iii) a sizing agent (e.g., epoxy) coated over the piezoelectric particles and surface of the electrically non-conductive fiber. Also described are composites in which the above fiber composition is embedded within a matrix, e.g., a polymer, ceramic, or glassy carbon matrix. Also described is a method for producing a passive sensing fiber composition by: coating a fiber having a surface with a liquid suspension containing piezoelectric particles suspended in a solvent; and removing the solvent to result in the piezoelectric particles adhered to the surface of the fiber. Also described are methods for detecting formation of defects in a material and methods of generating electrical energy from ambient vibration by use of the above described fiber compositions and composites thereof.

摘要： A method and system of assessing a condition of a boiler is disclosed. The assessing of the condition of the boiler establishes a baseline resistivity of a boiler waterwall for a first location of the boiler waterwall under a known temperature condition. A resistivity of the first location is measured under another temperature condition. The measured resistivity for the first location is compared to the baseline resistivity. A condition of the waterwall of the boiler is determined based on the comparison.

摘要： Systems and methods for detecting defects in pipelines are disclosed. In one embodiment, a method for detecting defects in pipelines includes: generating an electrical signal in a first pipeline by a signal generator electrically connected with the first pipeline and a second pipeline. A reflected signal is acquired by data acquisition equipment electrically connected with the first pipeline and the second pipeline. The reflected signal at least partially reflects from a defect in the first pipeline or the second pipeline. The method also includes analyzing the reflected signal to determine at least one of a location of the defect and a severity of the defect. In some embodiments, the first pipeline and a second pipeline are connected with a shunt cable.
