Abstract: A wind measurement apparatus includes: base and cover portions; N transducers disposed on the base portion in positions that serve as vertices of a convex regular polygon of order N (N≥3); and a reflector assembly arranged on the cover portion. The reflector assembly is divided into N substantially identical concave reflector portions. The reflector assembly and the base portion are disposed such that center points of the reflector assembly and the polygon are spatially aligned and each of the N transducers is spatially aligned with a respective boundary between two adjacent reflector portions. Each transducer is arranged to: transmit a TX beam towards the reflector assembly such that the TX beam meets the adjacent reflector portions on opposite sides of the respective boundary, and receive, via said adjacent reflector portions, partial reflections of the TX beams originating from those of the N transducers that are adjacent to the transducer.

Abstract: A wind measurement apparatus comprises: a frame assembly; four transducers mounted to the frame assembly such that their locations serve as vertices of a regular tetrahedron; and a reflector assembly mounted to the frame assembly, positioned substantially at a center of said regular tetrahedron to allow for airflow between the reflector assembly and the transducers. The reflector assembly comprises a reflector element provided as a solid that has eight vertices and six substantially identical concave faces that serve as reflector surfaces and that is oriented such that each transducer is facing a respective vertex of the reflector element. Each transducer is arranged to: transmit a TX beam towards the reflector assembly such that the TX beam meets the three reflector surfaces that meet at the vertex of the reflector element faced by the transducer, and receive, via said three reflector surfaces, partial reflections of TX beams originating from other transducers.

Abstract: The disclosure relates to a system for preventing gas bubbles in oil flow to enter a high-voltage device, which system is located in flow direction of the oil before the high-voltage device and comprises a gravitational gas bubble filter in which velocity of the oil flow is decreased by an enlargement of space for the oil flow and in which the gas bubbles in the oil are separated from the oil flow based on the effect of gravity. The invention also relates to a method for preventing gas bubbles in oil flow to enter a high-voltage device, in which method velocity of the oil flow is decreased by an enlargement of space for the oil flow and the gas bubbles of the oil flow are separated from the oil flow based on the effect of gravity.

Abstract: A method for visualizing weather data via a GUI accessible via a computer display is provided. The GUI provides a map view for displaying a weather map image and an interactive time selection view for displaying a time selection image. The method comprises composing the time selection image that depicts an arrangement of symbols jointly representing a current time period, each symbol representing a respective sub-period of time within the current time period and having an appearance that is descriptive of at least one precipitation characteristic in one or more precipitation data records that include weather data for the respective sub-period of time; receiving an indication of a user-selected time instant; and composing the weather map image by overlaying a weather image on a map image, wherein the weather image is derived on basis of a precipitation data record that includes weather data for the user-selected time instant.
