Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for optimizing a process of manufacturing a product. In one aspect, the method comprises repeatedly performing the following: i) selecting a configuration of input settings for manufacturing a product, based on a causal model that measures causal relationships between input settings and a measure of a quality of the product; ii) determining the measure of the quality of the product manufactured using the configuration of input settings; and iii) adjusting, based on the measure of the quality of the product manufactured using the configuration of input settings, the causal model.

Abstract: System and technique for inspecting a moving film by measuring the levels of light transmission through a thickness dimension of the film are described. The system includes a light source configured to provide light including a particular wavelength, or a particular range of wavelengths. The light from the light source is directed toward a first surface of the film, and an image capturing device is located adjacent to the light source on a second side of the film opposite the first surface, the image capturing device configured to measure the levels of light intensity exiting a second surface of the film. Measurements of the level of the light intensity passing through the film may be spatially synchronized to physical positions along the film to generated at least one roll map indicative of light transmission characteristics of the film over the imaged portions of the film.

Abstract: A method and associated system for providing robotic paint repair includes receiving coordinates of identified defects in a substrate along with characteristics of the defects, and communicating the coordinates to a robot controller module along with additional data needed to control a robot manipulator to bring an end effector of the robot manipulator into close proximity to the identified defect on the substrate. The characteristics of the defect and current state of at least the end effector is provided to a policy server that provides repair actions based on a previously learned control policy that is updated by a machine learning unit. The repair action is executed by communicating instructions for the repair action to the robot controller module and end effector.

Abstract: Techniques are described for inspection of films in order to detect Machine Direction Line (“MDL”) defects. An example system comprises a light source configured to provide a source of light rays, directed to a film product so that the light rays are incident to a surface of the film product at a non-perpendicular angle of incidence. An image capturing device is configured to generate an image of the film product by capturing a level of light intensity of the light rays exiting the film product in a plurality of image areas, each image area representing a line imaged across the film product that is perpendicular to a direction of manufacture of the film product. An image processing device is configured to process the image of the film product to provide an indication of the detection of one or more machine direction line (MDL) defects in the film product.

Abstract: A system for measuring dimensions of film to be applied to a window includes a plurality of removable cards for placement on the window, each of the plurality of removable cards having a plurality of visible correspondence points at pre-defined positions on the respective removable card. The system further includes a mobile device having an image capture device, and the image capture device is configured to capture an image of the window having a set of correspondence points visible in the image. Additionally, the system includes a server configured to receive the image of the window captured by the mobile device and process the image to determine dimensions of a film to be cut for the window based on the set of correspondence points and the pre-defined positions, and processing the image removes perspective distortions in the image. The system is configured to output the dimensions of the film.

Abstract: Techniques are described for maintaining synchronization of inspection data when a web roll is converted into intermediate smaller rolls prior to cutting the web into individual parts. A system comprises a database that stores anomaly data acquired from a manufactured web. The anomaly data specifies positions anomalies within a manufactured web relative to a set of fiducial marks on the manufactured web. A conversion processing line comprises a fiducial mark reader to output position information for the set of fiducial marks on the manufactured web, a slitter that cuts the manufactured web into slit rolls, and a fiducial mark printer to print a set of fiducial marks on each slit roll. A position monitoring system maintains spatial synchronization of the anomaly data by computing an updated position for the anomalies relative to the set of fiducial marks printed on the slit rolls.

Abstract: Techniques are described for automatically detecting defects in webs using ultraviolet light to excite fluorescing agents in various layers of the web. In one example. a system for detecting defects in the web includes an inspection device and a processing unit. The inspection device includes a lighting unit, a filter, and an image capture device. The lighting unit is configured to emit ultraviolet light having a first wavelength to the web, the web including a fluorescing agent configured to emit light having a second wavelength upon excitation by the ultraviolet light. The image capture device is configured to capture one or more images of the light having the second wavelength after the light has passed through the filter. The processing unit is configured to determine whether the web includes a defect based on the one or more images.
