Abstract: The invention is related to the radio communication area, in particular, to the personal radio communication technology and may be used in mobile telephony system. The method of mobile communication using a mobile repeater is implemented by a mobile communication device containing a central processor and a controlling memory. This mobile communication device is connected with a base station either by electromagnetic radiation, or through the mobile repeater by auxiliary emission. In some cases, the mobile repeater used to connect with the base station is selected by the central processor in accordance with a selection algorithm previously written into the controlling memory.

Abstract: The invention relates to systems for conducting interactive gaming measures, in particular to methods and systems intended for conducting interactive games, lotteries and sporting totalizators. The proposed system comprises a central computer which is coupled to a data transmission channel and to a precision time sensor and is connected via a communications channel to an information processing center, which is coupled to a return channel. In addition, the system comprises individual memory devices and a specific number of control units, each of which has an auxiliary microprocessor, which is connected to a set number of data interchange adapters, a display, a control memory and an input device. Furthermore, each individual memory device has an adapter for interfacing with the control unit, it being possible for said adapter to be coupled to any desired data interchange adapter.

Abstract: The invention relates to chess game playing method, in particular to a novel type of a chess game between two pairs of players. The inventive chess game playing device comprises at least two playing fields (7) which are divided into squares of two alternating colours, two sets of chess pieces, each of which consists of two groups (8, 9) of chess pieces (10-15) and two chess-clocks (2) each of which is provided with a timer (39) connected to two displays (3, 4) and to a control unit (41) which is used for switching said displays (3, 4). The chess game playing device also comprises means for exchanging data related to the location of the chess pieces (10-15) on the playing fields (7), each chess-clock (2) comprises a device for locking the control unit (41), wherein all timers (39) are interconnected.
