Abstract: A more simple and robust time synchronization of network subscribers compared to solutions known in the state of the art is provided by a device for time synchronization of network subscribers of a network based on satellites, having at least one satellite antenna connected to a receiving unit receiving a satellite signal containing time information. An electronic system that obtains the time from the satellite signal is connected to a time server with a network connection for the synchronization of the network subscribers using a network protocol. The complexity of the device is reduced and the common coaxial infrastructure between the receiving unit and the time server is removed for the satellite signal and replaced by a robust infrastructure.

Also included is a station clock having a network connection for the synchronization of the network subscribers using a real time network protocol. An electronic system, arranged in the head station or the station clock, receives the time information from the satellite signal. A bidirectional communication infrastructure connects the head station and the station clock.

Abstract: A medical system such as a diagnostic or a therapeutic system includes a fixed base unit with a control unit and a mobile assembly mounted rotatably on the fixed base unit. The fixed base unit and the mobile assembly are set up to exchange data. Transmission of first control data from the control unit to the mobile assembly takes place via a first transmission path. Transmission of second control data to the control unit and transmission of measured data from the mobile assembly takes place via a second transmission path.

Abstract: In a method and network for transferring data and signals between terminal equipment via one or more switching stations, the data and digitized signals are combined in cells, with each cell having a header in which connection information is contained that designates a transmission or routing target. The terminal equipment and switching stations are synchronized so that the cells are transferred in a synchronized manner via one or more switching stations. Signals and high quality of service (QoS) data thus can be transferred through the same network.

Abstract: The tension of a web in a multi-web system is regulated. At least two webs initially run through a first processing step independently of each other and are subsequently combined with each other to form one resultant web strand. The web tensions of these two initially independent webs are adjusted to each other through a first regulation process. Each of these webs has its web tension regulated on the separate web path by a dedicated second regulation process which is different from the first regulation process.
