Abstract: A window unit for an aircraft includes a wall module having a side wall laterally delimiting an aircraft cabin. The side wall has a window opening and the wall module has retaining portions. A window module has a window frame accommodating at least one windowpane and the window module has fastening portions. A fastening configuration fastens the window module on the side wall in a region of the window opening. The fastening configuration is formed by a respective fastening portion engaging with a respective retaining portion. The retaining portions and the fastening portions are movable into a plug-in position by a plug-in movement of the window module and are movable from the plug-in position into a securing position by a rotary movement of the window module. The wall module and the window module are interconnected by a form-locking connection in the securing position.

Abstract: A cover for an apparatus including a substrate defining the cover and having an exterior surface; a layer over the exterior surface of the substrate; a first portion of the substrate, underlying the layer, having a first composition and defining a first portion of the cover; a second portion of the substrate, underlying the layer, having a second composition and defining a second portion of the cover; wherein the first portion of the cover and the second portion of the cover are substantially opaque in exterior ambient lighting and the second portion of the cover is translucent to backlighting.

Abstract: A user replaceable cover for a flip part of an apparatus, such as a mobile cellular telephone. The user replaceable cover may overlie a display on the exterior of the flip part of the phone. The display is not visible through the cover in ambient lighting. However, when the display is activated the content of the display is visible through the cover.

Abstract: A user replaceable cover for attachment to and detachment from an apparatus including a first lateral part extending in a first direction, a second lateral part disposed opposite the first lateral part and extending in the first direction, a posterior part extending substantially in a second direction orthogonal to the first direction and joining the first lateral part and the second lateral part and an upper part having extremities and joining at the extremities the first lateral part, the second lateral part and the posterior part, wherein each of the first lateral part, the second lateral part, the posterior part and the upper part has an interior surface and an exterior surface, the user replaceable cover further including a plurality of sidewalls defined by the first lateral part, the second lateral part and the posterior part, wherein the sidewalls terminate at a lower edge for abutment with the apparatus; a face defined by the exterior surface of the upper part; an anterior edge defined at where the fi
