Abstract: In a method and device for the cyclic digital transmission of a position value of a moving object with inertial mass, the value range of the transmitted position value is restricted such that no complete rotation or, in the case of a linear motion, other complete period caused by mechanical conditions may be mapped, and the actual position is formed by detecting value-range exceedances in an evaluation unit.

Abstract: A method for bus arbitration is for use when working with multi-carrier modulation methods. Each user on a bus is assigned a unique address which identifies the user and which is transmitted upon each initiation of communication. The address is represented as a sequence of binary numerals, the number of bits of the binary numerals being equal to the number of carriers used in the multi-carrier modulation method. This sequence of binary numerals is transmitted successively for the arbitration via the multi-carrier modulation method, a user being eliminated from the arbitration when a further user at the same time has transmitted a binary numeral having higher priority. The transmission of the binary numeral may be repeated if the arbitration of the numeral does not lead to a result in one step. The method for bus arbitration may be used advantageously in a system for contactless energy supply. A redundant sending of phase-shifted signals reduces the failure rate because of random destructive interference.

Abstract: A method and device for the cyclic digital transfer of a position value of a moving object having inertial mass, the value range of the transferred position value being limited in such a way that no whole revolution or, in the case of a linear motion, other complete period that is conditional upon mechanical conditions is mappable, and the actual position is generated by detecting, in an evaluation unit, instances of the value range being exceeded.

Abstract: A method for assigning addresses to nodes of a bus system, and installation, bus nodes being furnished with an identical delivery address, where (i) an assigning entity, particularly a central computer, start-up computer or bus node sends information to the delivery address via the bus system, (ii) the information includes a first address, (iii) an action is performed whose effect is detected by a first bus node, (iv) the first bus node accepts the first address, (v) the first bus node sends a response to the assigning entity, (vi) steps (i) through (v) are repeated, each time with a further address for a further bus node.

Abstract: In a method for interference suppression of a signal composed of symbols, each symbol is transmitted twice in temporal succession as first symbol and second symbol, so that a segment of a symbol corresponds to a segment of the first symbol and a segment of the second symbol. An interference-suppressed signal is composed from the first and second symbols.

Abstract: A winding device for producing a field coil including a double-layer multiple-circuit winding for an electric motor includes a drive. The drive is configured to operate upon a winding mandrel with multiple lamellas arranged to be swung radially outwardly and inwardly by the drive in order to produce the double-layer multiple-circuit winding as a plurality of winding stacks that are arranged in separate slots and electrically connected in series, in parallel or both. At least two axially-separated winding stacks can be produced at the same time by the drive.

Abstract: A method and a device for bridging temporary power outages in a matrix converter are disclosed. In the event of a detected power failure, the matrix converter is disconnected from the power line and changes into a buffer mode in which a determined actual capacitor voltage space vector is regulated to a predetermined space vector. When the power line is reestablished, the actual capacitor space vector is synchronized and the matrix converter is reconnected to the power line during the synchronization. This allows a conventional matrix converter to take advantage of kinetic load buffering.
