Abstract: A keycap provides glyphs that are selectively visible. An exemplary keycap comprises a housing that has an at least partially transparent top side. A glyph made of a polarizing material is placed on the top side of the keycap. The glyph has a first plane of polarization. A liquid crystal panel is disposed inside the housing underneath the glyph. The liquid crystal panel is larger than the glyph above it. A polarizing filter having a second plane of polarization is arranged between the liquid crystal panel and a reflective carrier plate. Light enters the keycap through the transparent top side and is reflected at the bottom of the keycap by the reflective carrier plate. The reflected light is polarized by the polarization filter. The polarized light passes through the liquid crystal panel, which selectively rotates the polarization plane of light passing through it if the liquid crystal panel is active.

Abstract: Utility vehicle, in particular for military purposes, with a chassis and a cab arranged on it frame so that it can be tilted, and guarded in certain places by affixed armor plating. The cab has a front module and a rear module, whereby the front module has a front wall, two side walls, a rear wall, a floor and a roof forming a cabin for the driver and co-driver. The rear module has a bearer frame enclosed at least in part by walls that form a hood-like protective and stowage space for the power aggregate and other vehicle parts and accessories. The rear module is releaseably attached to the rear of the front module and supported by it. Rear armoring of the cab is implemented by armor plating fitted between its front module and rear module.

Abstract: A utility vehicles, in particular for military purposes, with a chassis and a cab arranged on the frame of said chassis so that it can be tilted. The cab has a front module and a rear module. The front module forms a cabin for the driver and co-driver. The rear module forms a hood-like protective and stowage space for vehicle aggregates, parts and accessories. The floor of the front module is reinforced by two longitudinal floor members extended through the front module rear wall by supporting brackets to support the rear module. There are supports so that the rear module, can rest on the extended supporting brackets of the longitudinal floor members. On the front module rear wall and at the front of the rear module bearer frame there are matching supporting and joining elements at different levels with flush boreholes or through-holes through which screws can be threaded to securely join the two cab modules on a longitudinal, crosswise and vertical axis, and also enabling them to be released.

Abstract: A multi-purpose recliner is provided having a recliner surface on which a person may recline and deployable for use inside and outside a vehicle, especially a military vehicle. The multi-purpose recliner includes a recliner surface material that can be rolled out, the recliner surface material forming the recliner surface and having a pair of receipt devices each extending along a respective length edge of the recliner surface material, and a disassembly-capable mount. The disassembly-capable mount includes a pair of stringers each being removably disposable in a respective one of the receipt devices of the recliner surface material and a pair of spacers releasably securable with the stringers. The multi-purpose recliner also includes a suspension structure for alternately retaining the recliner surface material in a rolled up condition and suspending the recliner surface material in a rolled out condition within the interior of the vehicle.

Abstract: A basic frame which may be arranged on the carrying chassis of a truck is provided. The basic frame, which is not described in detail, has a hollow beam and struts with supports at their ends that slide in the hollow beam. When the struts are extended the supports may be lowered to the ground so that military equipment such as a rocket launcher or signaling devices mounted on the basic frame, may project to the side without the truck being likely to topple over.

Abstract: Compensating brake fluid reservoirs with a brake fluid alarm device are required for master cylinders of hydraulic brake systems in automotive vehicles. A float chamber, which is disposed in a compensating reservoir and surrounds a float, is defined by a tubular body suspended from an upper end of the reservoir and a bottom element. After insertion of both parts into the reservoir the bottom element cooperates with the lower end of the tubular body such that the float chamber is closed at least to such an extent that the inflow and outflow of the fluid therefrom is inhibited in order to achieve a damping effect. This enables a quick immersion of both parts into the filled reservoir without brake fluid leaking from the reservoir.
