Abstract: A method and device for determining partial discharge in an electrical insulation system of a medium- or high voltage apparatus is disclosed with: detecting, with a sensing unit, an electrical signal that comprises partial discharge pulses due to dielectric breakdowns in the electrical insulation system of the medium- or high voltage apparatus; generating an in-phase and a quadrature-signal from the electrical signal comprising the partial discharge pulses in an I/Q-mixer unit by mixing the electrical signal including the partial discharge pulses with two local oscillator signals having the same frequency and a phase difference of 90°; filtering each of the in-phase and the quadrature signals with a low-pass filter; processing the filtered in-phase and the quadrature signals in a processing unit with a low-frequency Analog-Digital converter to obtain digital signals representing an in-phase and a quadrature value.

Abstract: A method for determining an estimated position of a vehicle includes: receiving a measured sensor response determined with a scanning sensor of the vehicle, which is scanning an environment of the vehicle and determining the estimated position of the vehicle by generating a virtual sensor response for a possible position of the vehicle from an environmental map; and comparing the measured sensor response with the virtual sensor response for determining, how much the possible position and a real position of the vehicle at which the measured sensor response was generated, coincide.

Abstract: A method and a system for determining a region of water clearance of a water surface are disclosed. The method includes receiving image data of an image captured by a camera, determining water surface pixels of the image from the image data, determining image coordinates of at least a first group of the determined water surface pixels in an image coordinate system, determining a position and an orientation of the camera at the time the image has been captured, determining real-world coordinates of the corresponding water surface in the real world by transferring at least the image coordinates of the first group to a real-world coordinate system under consideration of the determined position and orientation of the camera, and determining a region of the water surface, which is defined by the determined real-world coordinates of the first group, as the region of water clearance.

Abstract: A measurement system for determining a density ρ or a compressibility κ of a liquid medium in a vessel includes: at least one pressure sensor for measuring a hydrostatic pressure Δp of the liquid medium as a measured hydrostatic pressure Δp; at least one ultrasound sensor for measuring a first time of flight t1 along a first propagation path comprising a point at a level surface of the liquid medium, and for measuring a second time of flight t2 along a second propagation path, which is different from the first propagation path; and a control unit for determining the density ρ or the compressibility κ of the liquid medium based on the measured hydrostatic pressure Δp, the first time of flight t1, and the second time of flight t2.

Abstract: A signal processing unit configured to: cause a first ultrasound emitter, when attached to a wall of a vessel, to emit a first ultrasound test signal; receive, from at least one ultrasound receiver, when attached to the wall of the vessel, the first ultrasound test signal; detect a time of flight of the received first ultrasound test signal; and determine that an acoustic coupling of the first ultrasound emitter and a first ultrasound receiver of the at least one ultrasound receiver to the wall of the vessel is intact if the detected time of flight corresponds to a length of a path in the wall of the vessel from the first ultrasound emitter to the at least one ultrasound receiver.

Abstract: A system and method are described for post-processing 3D printed components. Post-processing may include removing support structures for the 3D printed components and may also include other processes like assembling 3D printed components into finished products. In the system and method, post-processing strategies are iteratively generated and performed on 3D printed components. Performance metrics of the post-processing strategies are compared with a user-defined performance indicator in a learning process to improve the post-processing strategy over a number of 3D printed components.

Abstract: A method of labelling a water surface within an image is provided. The method includes: receiving image data of the image generated by a camera, the image including at least one water surface; receiving water surface extension data, the water surface extension data being representative of an area over which the water surface extends in the real world; matching the water surface extension data to the image data based on a spatial relationship between the camera and the area of the water surface; and labelling the water surface in the image based on the matched water surface extension data.
