Abstract: An ablation system comprises: an ablation catheter and a console. The ablation catheter comprises: a shaft including a proximal end, a distal portion and a distal end; an ablation element configured to deliver energy to tissue; and a force maintenance assembly comprising a force maintenance element and configured to control and/or assess contact force between the ablation element and cardiac tissue. The console is configured to operably attach to the ablation catheter and comprises: an energy delivery assembly configured to provide energy to the ablation element. Methods of ablating tissue are also provided.

Abstract: A plant for producing an extruded silicone intermediate has a mixer/extruder for mixing and subsequently extruding a silicone compound for producing a raw silicone extrudate. A heating apparatus of the plant serves for crosslinking the raw extrudate to give the crosslinked silicone intermediate. The result is a plant with which a silicone intermediate of this kind can be produced more economically.

Abstract: A Wireless Local-Area Network (WLAN) access point includes a WLAN transmitter, a WLAN receiver, and a processor. The WLAN transmitter is configured to transmit WLAN packets via one or more transmit antennas, and to send a timing-synchronization signal over an internal interface. The WLAN receiver is configured to receive, via one or more receive antennas, echo packets including reflections from an object of a selected subset of the WLAN packets transmitted by the WLAN transmitter, to receive the timing-synchronization signal from the WLAN transmitter over the internal interface, and to time-synchronize the echo packets and the corresponding WLAN packets using the timing-synchronization signal. The processor is configured to estimate one or more parameters of the object based on the time-synchronized echo packets and WLAN packets, and to output the estimated parameters to a user.

Abstract: A rotor member is described for a gas turbine that is adapted for rotating about a central axis, the rotor member being a blisk having a rotor blade row that extends around the central axis or a rotor disk having a mounting portion for installing rotor blades of a rotor blade row that extends around the central axis, and being axially offset from the rotor blade row and/or the mounting portion and, extending coaxially, having at least one annular and axially asymmetrical sealing fin that has a radially outer tip portion having a front flank facing the rotor blade row and/or the mounting portion, and an opposite flank facing away from the rotor blade row and/or the mounting portion; the front flank being less steep than the opposite flank; a turbine and a compressor having such a rotor member, and a method for manufacturing such a rotor member having at least one sealing fin coating.

Abstract: An arrangement that includes a bus subscriber with two power supply terminals, at least one bus line terminal and a bus interface circuit for controlling a data flow via the at least one bus line terminal, wherein a controllable switch is located between the bus interface circuit and the at least one bus line terminal and the bus subscriber contains a sensor circuit which records the voltage between the power supply terminals or a voltage derived therefrom and closes the controllable switch if the recorded voltage exceeds a threshold value and opens the same if the recorded voltage fails to reach the threshold value, where with an arrangement including at least two bus subscribers, these bus subscribers are connected with their bus line terminals to a bus having at least one bus line and with their power supply terminals via two current lines to a shared voltage source.
