Patent number: 12358003Abstract: A gas cleaning device including a filter cartridge with a filter medium and a first filter terminal, a duct with a filter support that removably supports the filter cartridge in a volume of the duct in between the gas inlet and the gas outlet of the duct, and a gas ionizer that provides enhanced intrinsic safety against malfunction, ozone release and electric shocks of maintenance personnel. When the filter cartridge is inserted into the filter support, the first duct terminal contacts the first filter terminal and the first ionizer terminal is electrically connected with the first duct terminal via the first filter terminal. If the filter cartridge is removed from the filter support, the electrical connection between the gas ionizer and the duct terminal is interrupted.Type: GrantFiled: August 16, 2024Date of Patent: July 15, 2025Assignee: HENGST SEInventors: Stefan Robert, Andreas Borchard, Martin Rölver

Publication number: 20230368282Abstract: Extended reality auction techniques are described that support conducting live auctions in an extended reality environment, such as augmented or virtual reality environments. Image data, for instance, is received by a computing device from a first computing device depicting an item for auction. An extended reality auction system initiates an auction for the item based on identifying that at least part of the item is in the image data. The image data is provided to a second computing device for display in the extended reality environment during the auction. Responsive to determining that a criterion of the auction is not satisfied by the image data, remedial action is initiated by the extended reality auction system.Type: ApplicationFiled: May 13, 2022Publication date: November 16, 2023Applicant: eBay Inc.Inventors: Stefan Robert Francis Belavy, Antonio Haro, Andrew Chalkley, Deepak Rangaswami

Patent number: 10801377Abstract: A method for operating a rotation separator in an internal combustion engine, wherein, after the engine and separator have been switched off, it is determined whether there is a danger of the condensate in the separator freezing to ice because of cold ambient temperatures. If there is danger of ice formation, the separator is started up again by itself, i.e., without the engine being re-started, and is operated at a speed that effectively removes condensate from the rotor of the separator, so as to prevent icing of the separator.Type: GrantFiled: October 4, 2018Date of Patent: October 13, 2020Inventors: Stefan Robert, Martin Rölver
