Abstract: FIELD: printing industry.SUBSTANCE: invention relates to protective elements used for authentication of printed products. Protective element contains a polymer substrate coated with a transparent or semitransparent UV-cured lacquer without a relief layer containing flat flake-like pigment microparticles with a surface-coloured layer. Size of flakes in plane is 10–100 mcm. Microparticles are arranged so that their coloured surfaces are collinear and form equal angles with the plane of the substrate over the entire surface or in specified non-overlapping regions. Microparticles in the lacquer layer do not overlap each other and are contained in a concentration which ensures transparency of the protective element at level of 50–70 %. Images are recorded in a protective element by laser radiation on a surface-coloured layer to form images detected during visual inspection.EFFECT: technical result consists in improvement of the image quality of the protective element and simplification of the process of authenticating the product containing the protective element.3 cl, 2 dwg

Abstract: FIELD: military equipment. 
     SUBSTANCE: invention relates to defense equipment and can be used to increase efficiency of damaging action of multiple rocket launcher systems and cluster aviation ammunition. Method is based on blasting of submunitions supplied to an area target and placed at the specified distance determined from an analytical expression. Distance is provided by interaction of gas-dynamic streams of reacting substances and afterburning of the mixture of active products with atmospheric oxygen. For this purpose, an information center for monitoring delivery to an area target of submunition is created. Each of them is equipped with a beacon operated during interaction of submunition with an area target. After observing the fact of delivery of all submunitions by the observation center, a common command is formed to blow submunitions. Submunition for their delivery to the surface target is extracted from the cluster ammunition in the specified points of the trajectory. At non-arrival after a given time of the command from the observation information center for the sub-munition explosion, the explosive is detonated from the ammunition fuse. 
     EFFECT: technical result is higher probability of destruction of target area by providing simultaneous detonation of landed submunitions formed as a result of actuation on trajectory of several cluster warheads of shells of rocket launcher rocket systems or cluster aviation ammunition.
