Abstract: A system is provided for determining the movement of an interventional device inside a lumen. The interventional device comprises a distal portion inside the lumen and a proximal portion outside the lumen and the system comprises a processor. The processor is configured to receive one or more images from an ultrasound transducer, wherein the images are representative of the lumen with the interventional device inside and input the one or more images into a machine learning algorithm.

Abstract: The present invention relates to a method of coating one or more metal components of a fuel cell stack, such as a bipolar plate, an electrode, gaskets etc., the method comprising the steps of providing an uncoated metal component; etching said uncoated metal component; optionally depositing an adhesion layer on the etched uncoated metal component; and depositing a carbon coating on either the adhesion layer or on the etched uncoated metal component, with the adhesion layer and the carbon coating respectively being deposited by means of one of a physical vapor deposition process, an arc ion plating process, a sputtering process, and a Hipims process. The invention further relates to a component of a fuel cell stack and to an apparatus for coating one or more components of a fuel cell stack.

Abstract: An apparatus for coating substrates includes a vacuum chamber having an opening through which substrates can be received and a door configured to seal the opening; one or more targets arranged in the vacuum chamber; a cooling unit configured to cool the substrates and/or a heating unit configured to heat the substrates; rotating means configured to rotate substrates relative to the one or more targets, the cooling unit and/or the heating unit; and a lifting chamber that communicates with the interior of the vacuum chamber and is configured to receive the cooling unit and the heating unit. The vacuum chamber defines a lifting axis along which the cooling unit and/or the heating unit and the lifting chamber are arranged, and the apparatus further comprises displacement means configured to displace the cooling unit and/or the heating unit along the lifting axis and between the vacuum chamber and the lifting chamber.
