Patent number: 11747513Abstract: A sensor apparatus for detecting a target object influenced by a process or formed in the process includes a sensor unit and an evaluation device. The sensor unit detects the target object in a detection zone of the sensor unit and generates a sensor signal that can be influenced by the target object. The evaluation device processes the sensor signal as a first input variable and generates an output signal, which indicates the detection of the target object, in dependence on the sensor signal. The evaluation device further processes a process parameter of the process, which acts on the target object, or a target object parameter, which characterizes the target object and is influenced by the process, as a respective further input variable and to generate the output signal in dependence on the process parameter and/or the target object parameter.Type: GrantFiled: December 20, 2018Date of Patent: September 5, 2023Assignees: SICK AG, TRUMPF WERKZEUGMASCHINEN SE + CO. KGInventors: Jens Ottnad, Dennis Wolf, Kevin Lutz, Christoph Blömker, Michael Burger, Peter Steurer, Günter Hirt, Stefan Kienzler

Patent number: 6998631Abstract: An optoelectronic sensing device detects two contrasting marks arranged next to each other along two reading tracks on a moving web. An optical head is arranged above each reading track. Each head has a lighting source and a lens, by means of which the contrast marks are imaged on an associated light receiver. Information from the contrast mark is obtained from the output signal of the light receiver. An adjustable connector joins two substantially identical optical heads to each other so that their respective lenses are arranged asymmetrically in the associated optical head and are situated in immediate proximity to each other, which permits adjustment of the device for the smallest possible track spacings.Type: GrantFiled: February 23, 2004Date of Patent: February 14, 2006Assignee: Sick AGInventors: Guenter Hirt, Matthias Opfolter
