A wallpaper system presents a first wallpaper image of a wallpaper video to a user and receives, via a user input device, one or both of: (i) a spatial user input selection, and (ii) a time user input selection from the user to apply to the wallpaper video. In response to detecting one or both of: (i) the spatial user input selection, and (ii) the time user input selection, the wallpaper system determines one or both of: (i) a respective spatial movement parameter within a wallpaper video associated with the spatial user input selection, and (ii) a respective time coordinate within the wallpaper video associated with the time user input selection. Wallpaper system presents, via the image display, a second wallpaper image associated with one or both of: (i) the respective spatial movement parameter, and (ii) the respective time coordinate.

A method is disclosed for plasma-based conversion of methane in a plasma reactor, the plasma reactor (1) comprising a reaction chamber and an energy source to create the plasma in the reaction chamber, the reaction chamber being fluidly connected to a post-plasma reaction chamber, the plasma reactor comprising a gas inlet, the post-plasma reaction chamber comprising a gas outlet, the method comprising: a) generating a plasma in the reaction chamber by activating the energy source; b) providing a first gas flow comprising a CH<4> component through the gas inlet and into the reaction chamber, allowing conversion of the CH<4> component into gaseous H<2> and solid carbon and allowing the continuous removal of produced H<2> through the post-plasma reaction chamber and through the gas outlet; c) in consideration of a solid carbon deposit being formed on a predetermined portion of an inner wall of the post-plasma reaction chamber, replacing the first gas flow with a second gas flow, the second gas flow comprising a COz component, allowing the oxidation of the deposited carbon, and allowing the continuous removal of produced CO through the gas outlet until the deposited carbon is substantially removed; and associated reactors and reactor systems.

An air cleaner comprising: a) a housing b) a cover; c) a filter element within the housing; wherein the surrounding housing-wall defines a pair of opposing receiving V-shaped grooves; wherein the filter element comprises first and second protrusions extending from opposing sides of the filter element and arranged along a common axis; the protrusions being adapted and arranged within the receiving grooves such that the filter element can be rocked about a pivot axis defined by pivot points of the first and second protrusions within the housing pivot the filter element into sealing engagement with the housing; and wherein the protrusions comprise a first leg which is in contact with said first leg of said V-shaped grooves and extends in a direction perpendicular or about perpendicular to a longitudinal axis of the filter element and/or an axis of said filter housing to block a movement of the filter element in a direction towards the inlet arrangement and to block a rotation of the element around its pivot points in a first rotation direction; and associated filter element.
