  • Patent number: 8619625
    Abstract: An autonomous network has a plurality of autonomous terminals, equipped with at least one programmable transceiver, and which are embodied to independently identify frequency ranges provided for a communication link and used to reconfigure the programmable transceiver thereof. One or more technical system states of the network, with which a specific operation of the network is described, is defined. One or more sets of rules are defined for the autonomous terminal, one rule comprising authorized operational states and/or configurations of the autonomous terminals. The effects of the actual operation state and/or configurations of the autonomous terminals on the actual system state of the network is monitored. The sets of rules and/or definition of new rules, which comprise actual operational states or configurations of the autonomous terminals, is adapted when the actual system state of the network differs from the defined system state of the network.

  • Publication number: 20130091565
    Abstract: A method for access control and session control of electrical producers and/or consumers in accessible energy transfer units is provided, wherein the producer or the consumer is authenticated and authorized at the energy transfer unit, and producer- or consumer-specific data are forwarded by the energy transfer unit to an energy provider after authentication and authorization of the producer or the consumer. A temporarily-valid session token is generated for the control of the energy transfer by the energy provider, and forwarded to the energy transfer unit and the producer or the consumer. Electrical energy is transferred between the energy transfer unit and the producer or the consumer, wherein in a defined time interval during the energy transfer process the session token is sent at least once by the energy transfer unit to the producer or the consumer and from the producer or the consumer to the energy transfer unit.
