摘要： A system for autonomously diagnosing a defect in a component to which a penetrant has been applied and at least partially removed for penetrant testing comprises: a device for positioning the component for inspection; a camera configured to take an image of the component when positioned by the device; and a first image evaluation module configured to: process the image of the component with a machine learning algorithm to detect from the image remaining penetrant on the component and based on characteristics of any detected penetrant to provide a first determination of whether or not the image indicates a defect in the component. A corresponding method is also disclosed.

摘要： This disclosure describes multi-fluid kits for three-dimensional printing, three-dimensional printing kits, and methods of testing powder bed material for contamination. In one example, a multi-fluid kit for three-dimensional printing can include a fusing agent and a detector solution. The fusing agent can include water, an electromagnetic radiation absorber, and a first pigment reactant. The electromagnetic radiation absorber can absorb radiation energy and convert the radiation energy to heat. The detector solution can include water and a second pigment reactant. The second pigment reactant can be reactive with the first pigment reactant to form a

摘要： A method for visualizing biofilm on a solid surface. The method comprises steps of:
(a) providing a solid surface which has been in contact with an aqueous medium and at least a portion of the solid surface potentially is covered with biofilm, (b) maintaining the solid surface in a horizontal position and covering the solid surface with an aqueous dispersion of carbon particles, (c) tilting the solid surface at an angle of at least 5° from horizontal to allow excess aqueous dispersion of carbon particles to flow from the surface, (d) detecting any biofilm present on the solid surface by determining whether there are areas not covered by aqueous dispersion of carbon particles.

摘要： A crack detection method includes a crack forming step of applying a laser beam to a plate-shaped workpiece that has a first side and a second side opposite to the first side linearly from the first side with a focal point of the laser beam positioned inside the workpiece, the laser beam being of a wavelength having a transmitting property to the workpiece, to thereby form a modified layer inside the workpiece and further form a crack extending from the modified layer toward the second side, a coating material applying step of applying a coating material to the second side, and a crack detecting step of detecting the crack by searching for a portion where the coating material is linearly repelled.

摘要： A device for emitting electromagnetic radiation, in particular UV radiation, including at least one radiating unit that only emits radiation at visible wavelengths. The device further includes a unit for detecting a functional error of the radiating unit. In practice, the radiating unit is provided for emitting only UV radiation and/or IR radiation and is formed by a light diode. The detection unit is designed to continuously monitor the radiating unit for functional errors, and the device includes an open-loop and/or closed-loop control unit which is provided to automatically switch off the radiating unit and/or display the functional error, upon detection of the functional error by the detection unit.

摘要： An inspection system includes an imaging device, visible light source, ultraviolet light source, and at least one processor. The imaging device generates a first image set of a work piece while the ultraviolet light source illuminates the work piece with ultraviolet light to cause fluorescent dye thereon to emit light, and generates a second image set of the work piece while the visible light source illuminates the work piece with visible light. The first and second image sets are generated at the same positions of the imaging device relative to the work piece. The processor maps the second image set to a computer design model of the work piece based on features depicted in the second image set and the positions of the imaging device. The processor determines a defect location on the work piece based on an analysis of the first image set and the computer design model.

摘要： A method and apparatus for undertaking remote non-destructive in-situ testing an elevated wind turbine blade includes the steps of providing a remotely controlled drone aircraft, applying a water soluble penetrant from the drone aircraft to a test surface area of the turbine blade, and then waiting for the water soluble penetrant to dry. Next, a dry powder developer is applied from the drone aircraft to the test surface area, and then awaiting for the dry powder developer to substantially set. The test surface area is then illuminated with an ultraviolet light source from the drone aircraft. Lastly, the test surface area is digitally photographed to effect an inspection for visible latent defects. Additionally, a solvent can be applied from the drone aircraft to rinse the test surface area of the wind turbine blade after waiting for the water soluble penetrant to dry and prior to applying the dry powder developer.

摘要： The present invention provides a non-destructive method of characterizing CMAS infiltration and CMAS assisted damage in thermal barrier coatings (TBCs). Such approach is especially relevant for determining the lifetime of coatings on e.g. turbines or parts of the turbines such as blades or in-liners of the combustion chambers. The turbines can be gas turbines or high-pressure turbines or others and may be stationary or used for example in aviation.
