Abstract: A kit for a modular radar system is provided. The kit includes a basic unit with a housing, a top cover and a bottom cover. A first circuit board with a first plug connector is fastened to an underside of the basic unit. The basic unit is subdivided into a first and second cell by partition walls. The first cell includes a radar module and the second cell includes a second circuit board. The top cover has a radome in the area of the first cell. The bottom cover includes a power supply module and a data interface module. The upper side of the bottom cover includes at least one plug connector for connecting to a plug connector on the underside of the first circuit board and to connect the power supply module and the data interface to the processing unit and/or the radar module.

Abstract: Stencils of a desired design are made by selective hardening of first and second individually soluble substances being hardenable in admixture in a foraminous stencil blank, which is initially impregnated with the first substance. The second substance is stored separately from such impregnated stencil blank, such as in a pen. This separately stored second substance is thereafter selectively applied in the form of the desired design to the impregnated stencil blank for admixture with the first substance only immediately prior to a desired selective hardening of the admixed first and second substances, to render part of the stencil imperforate. A stencil is also exposed to dissolution of any applied first and second substances outside of the latter part, for rendering the stencil perforate outside of that part.

Abstract: Screen printing and stencil articles, apparatus and methods provide a stencil including a screen and photosensitive emulsion for selectively stopping areas of the screen upon photographic exposure and development. One or more sheets are adapted to receive an image pattern through which the photosensitive emulsion is to be exposed. The photosensitive emulsion is shielded against spurious exposure. The screen with shielded photosensitive emulsion and the one or more pattern receiving sheets are combined into a unitary stencil making assembly.A stencil comprises a rectangular screen having meshes. A first area on the screen is stopped and a second area adjacent the first area comprises open meshes of the screen. A first elongate screen mounting member is attached to and extends along a first side of the screen. A second elongate screen mounting member is attached to and extends along an opposite second side of the screen. The screen itself is self-supporting between the first and second mounting members.
