Abstract: A method for organizing a data transmission network relates to information technologies and is intended to create an information transmission network between two or more points at a distance. The technical result of the claimed solution is a simplification in structure and a reduction in build time and the cost of network usage. The method is built on a node indexing algorithm based on a minimum number of packet retransmissions from modem to node. The method allows the use of a plurality of optionally moveable modems in a network and the use of wired and wireless networks, does not require the presence of a powerful base station, does not require additional time for rebuilding a network when signal transmission conditions are changed or when the number of nodes in a network is changed, allows a network structure to be built and the built structure to be further optimized, and does not require the nodes to store information about the network environment, which substantially lowers the cost of the solution.

Abstract: The invention relates to lighting technology and specifically to LED lighting devices. The LED device contains walls which delimit a housing cavity of the LED device, said walls being made of electrically insulating material, and at least one of the walls being provided with a recess capable of accommodating a current source, which allows for replacing the current source without disassembling the lamp and also increases electrical safety in using the lighting device by means of excluding galvanic mains decoupling elements.

Abstract: The invention relates to electrical network communications engineering and can be used in systems for automatic data collection from intrusion protection and fire alarm sensors, electric, heat, water, gas meters and fiscal memory data devices for cash registers. The technical result is significant reduction of power consumption in transmitters of system slave units and/or expansion of its operation. A unique random or pseudo-random set of initial phase differences for the adjacent harmonic pairs is used to encode each character of transmitted data, and these sets of initial phase differences are selected in such a way as to minimize crest factor of a total signal. When a fire-alarm sensor is actuated, it is sufficient to transmit only one symbol to an alarm panel which, unambiguously identifies the location of the active sensor and as a rule is embodied in the form of a conventional number or address pre-allocated to the sensor.

Abstract: The set of inventions relates to display engineering and is used for displaying color alphanumeric and graphical information for designing and developing different infomercial display means on externally and internally located objects. The said invention makes it possible to improve the quality of displayed information, the operational reliability thereof and to reduce the costs by that the structural design and the arrangement of light clusters in the information desks of columns are optimized, and required dimensions of the information desks and the distance therebetween when a video field image is formed are determined. The elements of the running letters consist of two adjacent pixels having a common light-emitting-diode and the inventive arrangement configuration of the light-emitting-diodes in a pixel makes it possible to control the image resolution.
