Abstract: A radar level gauge system for determining the filling level of a product in a tank, comprising a transceiver, an elongated propagation device, and processing circuitry coupled to the transceiver for determining the filling level. The propagation device comprises a first propagation device part comprising a cuff portion; and a second propagation device part comprising an end portion inserted in the cuff portion and joined together with the cuff portion by at least a first fastening arrangement. The first fastening arrangement comprises: a tab formed in one of the cuff portion and the end portion; and a recess formed in the other one of the cuff portion and the end portion. The tab is received by the recess to interact with the recess to prevent relative movement between the first propagation device part and the second propagation device part at least in the longitudinal direction.

Abstract: A screw-shaped anchoring fixture for anchoring a prosthesis in the skull bone. The anchoring fixture comprises a main body configured to be implanted into the bone and a flange configured to function as a stop to prevent the main body from completely penetrating through the bone. The main body comprises a distal tapered apical portion, a first portion, and a second portion. The inner diameter of the second portion is greater than the inner diameter of the first portion. The method for inserting the anchoring fixture includes providing the anchoring fixture, drilling a hole, and inserting the anchoring fixture into the hole until the flange contacts the skull bone, wherein the hole has a diameter that is greater than the inner diameter of the first portion and less than the outer diameter of the second portion.

Abstract: A coupling apparatus for a bone anchored hearing device for anchoring hearing aid devices or extra-oral prostheses in the form of ear and orbital prostheses in the skull bone. The apparatus comprises a screw-shaped anchoring fixture configured to be inserted into the skull bone and a skin-penetrating abutment coupled to the fixture by a screw connection. The fixture comprises a main body with an external screw thread and a flange having a substantially planar bottom surface. The flange is configured to stop the anchoring element from penetrating through the skull bone. The skin-penetrating abutment comprises a substantially conical outer surface. The upper end surface of the fixture is designed with an open cavity with a tapered inner contour forming a seat for the bottom part of the abutment. The bottom part of the abutment is configured to create a good connecting fit between the fixture and abutment.
