  • Patent number: 11679943
    Abstract: An apparatus for stacking and coating of very short cavity laser diode arrays. The apparatus includes an array holder fixture to securely hold the very short cavity laser diode arrays and spacer arrays, and a stacking plate. The array holder fixture including a top-side presser to secure a stack of very short cavity laser arrays and spacer arrays from a first end of the stack, a bottom-side presser to secure the stack of very short cavity laser arrays and spacer arrays from a second end of the stack, and a pair of side clamps. The array holder fixture is operatively coupled to the stacking plate during the stacking of the very short cavity laser diode arrays and spacer arrays.

  • Patent number: 11190552
    Abstract: A gateway or corresponding computing device acting as a gateway in an IoTSP system, for example, is provided with gateway configurations defining at least how to monitor functionality of the gateway. The gateway monitors its functionality according to the gateway configurations. The monitoring may relate to telemetry data, hardening, and/or external experience data.

  • Patent number: 8060234
    Abstract: There is described a method and apparatus for tracking the location of web features through a converting process, one application of which can involve tracking paper defects from a paper machine as detected by a camera system, to a winder where the sheet is wound to rolls so that the web defects can be repaired in the winder before making the rolls. The method to track web features is based on pattern identification of inherent sheet variability or defects. The apparatus involves two or more sheet property or defect monitoring web sensors arranged at the same cross directional location at different stages of the converting operation, augmented by tachometers and/or roll diameter sensors. A full automation system for drive control on the winder based on this information is preferably added to make maximum advantage of this information.

  • Patent number: 8023720
    Abstract: In an exemplary method, repeated patterns are identified in a strip-like product. In the method the strip-like product is observed by at least one camera, and at least one digital image signal comprised of pixels is created for inspection. The image signal is searched for anomalies comprised of one or more pixels. A search image is created of any detected anomaly and its neighbourhood, and the search image is used to convolute the image signal being examined, creating a response image signal. The response image signal is used to determine image areas in the image signal being examined that are substantially similar to the search image.

  • Publication number: 20050135667
    Abstract: A method for labeling images that have a visual appearance digitizes the images in order to create image data. The method calculates plurality of features from a subset of said image data and organizes the images unsupervised in an organization process. The organizing is based on the features and the similarity criterion. After the set of images is retrieved utilizing the organization of the stored images, a label is assigned to the retrieved image or to its part. As well the labels are verified and training material is created for a supervised classifier.
