A connecting device for a plug-in connection of at least one pipeline having a housing part having at least one receiving opening for the insertion of the pipeline. The vibration damper is an actively regulated axial magnetic bearing. Photodiodes capture light reflected back from the pulsing blood. A portion of the electrical connector is seated onto the support members, with the mounting portions of the contact terminals of the connector exposed. The invention also gives a solution for an improved compensation method which is based on a dragging of sub-field code word entries along a motion vector direction to a current pixel. The firewall allows the outside entity to access the internal computer system to control the device if the outside entity can provide proper identity information.
