Abstract: Public safety (PS) communication devices are provisioned at an incident scene to communicate with each other in a common talk group configuration. Talk group information is contained in a beacon message that is broadcast by an initiating PS device in an access point mode of operation via a Wi-Fi network protocol compatible with at least one version of IEEE standard 802.11. The beacon message is received via the same Wi-Fi protocol at another PS device in a station mode of operation and processed to configure the other PS device with the talk group information.

Abstract: The invention relates to building construction and to the production of building products and can be used for constructing low rise residential, industrial and administrative buildings for different climatic zones. The invention increases the quality of products having a complicated configuration, extends the range thereof and makes it possible to obtain a precise geometrical shape of the products. The inventive general-purpose multicavity cassette mould for producing grouted building keyblocks comprises a frame provided with a tray (1) on which lodgements (2) are arranged, the number of the lodgements corresponds to the number of formed sections. A crossbeam (3) being the lower in the operative position thereof is provided with fixing elements. Rotatable coupled pull rods (4) are provided with clamping elements (5). A demountable crossbeam (6) being the upper in the operative position thereof is also provided with the fixing elements.

Abstract: The invention relates to building construction and to the production of building products and can be used for constructing low rise residential, industrial and administrative buildings for different climatic zones. The invention increases the quality of products having a complicated geometric configuration, extends the range thereof and makes it possible to obtain the precise geometrical shape of the products. The inventive universal multicavity cassette mould is embodied in such a way that it is multisectional and has the form of crest-forming elements rigidly fixed to a frame, articulated drop sides being also fixed to the frame. Groove-forming and crest-forming elements are fixed to the opposite longitudinal sides, respectively. The articulated drop sides are provided with locking elements, the upper groove-forming elements being disposed in such a way that they are dismountable.
