Abstract: A communication device includes a transceiver unit for receiving from a central installation a broadcast message containing information for initiating communication between the communication device and the central installation, and a control unit for selecting a hardware address for the communication device in response to the information contained in the broadcast message. The selected hardware address can be used for addressing the communication device for messages from the central installation. The transceiver unit is designed to communicate with the central installation using the selected hardware address for the duration of a session. The control unit is designed to delete the selected hardware address after the duration of the session has expired. Selecting a hardware address randomly and deleting the hardware address after the session has expired allows communication between the communication device and the central installation, while maintaining the identity of the communication device anonymous.

Abstract: A network including network nodes that are arranged in a ring topology. At least one of the network nodes includes middleware. The middleware includes a redundancy protocol that is implemented on the application level in a network stack. In order to ensure a functional capability of the network, the ring topology is monitored with the redundancy protocol.

Abstract: A method for operating a process automation system that is configured to control an industrial process and/or traffic-control signals, wherein the process automation system includes field devices arranged in a field of the industrial process and a central controller unit for controlling the process through the field devices, where the central controller unit generates control data for the field devices by running a control program, where the control program forms a browser executable application that receives and processes field data from the field devices and generates and sends out the control data, and where the central controller unit executes an internet browser program and the internet browser program runs the application.

Abstract: A measurement method, used when there is a fairly large distance between a vehicle and a charging station, determines a distance by way of absolute propagation time measurement. In a proximity zone between the charging station and the vehicle, a relative propagation time measurement is carried out between received signals.

Abstract: A pharmaceutical dosage form for administration twice daily, once daily or less frequently, which contains 6?-fluoro-(N-methyl- or N,N-dimethyl)-4-phenyl-4?,9?-dihydro-3?H-spiro[cyclohexane-1,1?-pyrano[3,4,b]indol]-4-amine or a physiologically acceptable salt thereof.

Abstract: In a method for communicating between a number of first services and a number of second services. The number of first services belongs to a service-oriented architecture, in which a respective first service is provided by messages based on a question-answer mechanism by a first protocol. The number of second services belongs to a data-based architecture, in which second services can be switched together by a second protocol. The second protocol specifies data input and data output of the second service and transfers the data between the second services. A message of a first service, entering into the service converter, is converted into data input of a second service associated with the first service and/or data output of a second service, entering into the service converter is converted into a message emitted by the service converter, of a first service associated with the second service.

Abstract: The resource consumption of automation systems having a service-oriented architecture is monitored by determining individual parameters for the resource requirement and the processing performance for individual subfunctions, respectively, within the service-oriented architecture. Critical subfunctions can therefore be reliably identified and adapted, if necessary, by individually analyzing the processing parameters for individual subfunctions during event-controlled processing.

Abstract: A device for bleeding compressor air in a turbofan engine includes a low-pressure compressor of a primary duct, a fan stator arranged in a secondary duct downstream of a fan, and an arrangement for discharging compressor air from the low-pressure compressor into the secondary duct. The arrangement includes air guiding devices to guide compressor air into the secondary duct upstream of the fan stator relative to the flow direction in the secondary duct, past the stator vanes of the fan stator in a separate duct in the axial direction and is only mixed with the air of the secondary duct downstream of the fan stator. The separate duct is formed by a plurality of hollow structures extending in the longitudinal direction each between two adjacent stator vanes of the fan stator, with the hollow structures having a closed circumference in cross-section.

Abstract: The invention relates to a method and an apparatus for querying at least one value of at least one parameter of a module and to a method and a module for providing at least one value of at least one parameter. In this case, a basic scheme is extended by at least one query function to form a scheme, wherein the scheme makes it possible both to configure the module and to query individual values or a plurality of values.

Abstract: In a method and a device for placing units, such as motes, for executing an application in a distributed system, a placement of the units by a service layer and a communication between the units by a communication layer are provided. One field of application is for example process automation, such as in industrial or building management installations. Such installations have sensors and actuators with communication interfaces. The method and the device allow the energy demand of the installation to be reduced. Communication is preferably performed wirelessly. Network management is for example conducted according to the wireless HART protocol.
