Abstract: An apparatus for contactless transportation of a device in a vacuum processing system is described. The apparatus includes: a magnetic transportation arrangement for providing a magnetic levitation force (FL) for levitating the device, the magnetic transportation arrangement comprising one or more active magnetic units; a sensor for monitoring a motion of the device, and a controller configured for controlling the one or more active magnetic units based on a signal provided by the sensor.

Abstract: A perfusion loop assembly for ex vivo liver perfusion includes a pump providing perfusion fluid through a line branching at a branching point into a first branch line and a second branch line. The first branch line provides a first portion of the perfusion fluid to the hepatic artery of the liver, the first branch line coupled with a gas exchanger, where the first branch line includes a flow rate sensor and/or a pressure sensor. The second branch line provides a second portion of the perfusion fluid to the portal vein of the liver; the second branch line includes a valve for controlling flow of perfusion fluid into the portal vein. The second branch line includes a flow rate sensor and/or a pressure sensor. A liver chamber assembly holds the liver ex vivo, and an outlet line for the perfusion fluid connects the liver chamber assembly and the pump.

Abstract: For simpler and more rapid testing of a front-end module, additional linked operating states are provided in the switch and/or its decoder and allow a plurality of paths to be enabled in parallel, in order in this way to test these paths with a smaller number of test routines in a test set, in particular a network analyzer.
