Abstract: An electronic assembly has a plurality of functional units each including a board element populated with electronic modules, which board element has in each case a number of contact locations arranged in at least one row, and a contact board, which has for each board element at least one row of contact receptacles that are directly electrically connected to the contact locations of the associated board element. These rows point toward a side of the contact board in their longitudinal direction. A plurality of similar assemblies are produced compactly and cost-effectively by providing a communication unit separate from the contact board and serving for communication with modules of the board elements. The communication unit is connected to the contact board via a plurality of data lines which are contact-connected to the contact board on the side to which the rows point.

Abstract: An optical device forms a beam path between an optical end element at a beam path end and an object scene into which the beam path is directed via a field of view of the end element. The optical device contains an alignment device for pivoting the field of view relative to a predetermined direction, an end optical unit and an optical articulation for guiding the beam path from the pivoted field of view into the end optical unit. In order to achieve good shielding against spurious radiation, the device has a shielding unit containing a shielding element led partly around the optical articulation, which shielding unit shields the optical articulation against incident radiation that is not incident through the entrance or exit aperture of the optical articulation.

Abstract: A propellant charge for use for ammunition, in which the propellant charge is separate from the projectile, has a propellant charge substance which can be initiated by a fuse. In order to solve the problem of providing a propellant charge for use in a two-part munition, which on the one hand can be produced easily and at low cost and on the other hand does not present any risk of damage when mechanically loaded before use, it is proposed that a propellant charge casing be provided which surrounds the propellant charge substance, with the propellant charge casing being in the form of a plastic part which is composed of a non-combustible, temperature-stable plastic material.
