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.

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.

Accurate tracking of web features through converting processes

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.
