Abstract: A communication method for at least one mobile terminal of a user, suitable for setting up data connections or call connections via at least one mobile communication network to a data terminal or to a voice terminal and suitable for the wireless communication with a host server. Thereby a) a wireless communication link is established between the host server and the mobile terminal; b) a voucher is created by the host server; c) the voucher is transmitted to the operator of the mobile communication network or to a service provider; and d) the operator of the mobile communication network or the service provider, on the basis of the voucher, debits communication costs for data connections or call connections of the mobile terminal that were registered during the time period indicated in the voucher, at least in part to an account assigned to the identifier of the host server.

Abstract: Method for controlling a technical system including a power grid, connected to at least one energy supply system. The method ensures that the consumption of electrical energy of the grid is within a given load curve by avoiding or compensating peak loads; including the steps of: a) providing data of the total load occurring in the grid to a load data processor; b) the processor processing said data and determining curves of a plurality of load components of the total load; c) determining future load curves for each component for a time period ahead; d) superimposing the future load curves and determining a future total load curve for the future total load and future peak loads; and e) controlling the technical and/or energy supply systems based on the determined future total load curve to avoid exceeding given load limits and future peak loads or allocate energy required in the future.

Abstract: An identification system which may be employed in a transport or monitoring system has at least one stationary and at least one mobile transmission unit which are each provided with an antenna, which antennas in turn are coupled inductively or capacitively to each other during the transmission of data. At least one of the antennas is designed such that in response to a mutual displacement of the coupled antennas a direction-dependent modulation of the transmitted signals occurs which is demodulated and evaluated in at least one of the transmission units, for example, by a demodulation unit and a processor, optionally a signal processor, in order to obtain information relating to the relative motion of the two transmission units. In addition to known identification functions, the identification system may perform additional important functions without requiring any significant additional expense.
