Abstract: A method for obstacle detection for a rail vehicle includes determining a monitoring region in front of the vehicle based on position and course of a track which the vehicle travels and position and dimensions of a monitoring profile of the vehicle. During the determination, sensor data for determining position and orientation of the vehicle are captured and position and course of the track which the vehicle travels are determined based on alignment of the determined position and orientation of the vehicle with digital map data. Objects in the vehicle environment are captured by sensors of the vehicle. Which objects are potential collision obstacles is determined by checking whether and to what extent they overlap with the monitoring region. A reaction to the objects categorized as potential obstacles is determined based on geometric and kinetic attributes of the objects. An obstacle detection device and a vehicle are also provided.

Abstract: The present disclosure relates to systems, methods, and non-transitory computer-readable media that modify digital images via scene-based editing using image understanding facilitated by artificial intelligence. For instance, in one or more embodiments, the disclosed systems generate utilizing a segmentation neural network, an object mask for each object of a plurality of objects of a digital image. The disclosed systems detect a first user interaction with an object in the digital image displayed via a graphical user interface. The disclosed systems surface, via the graphical user interface, the object mask for the object in response to the first user interaction. The disclosed systems perform an object-aware modification of the digital image in response to a second user interaction with the object mask for the object.

Abstract: A method for providing teeth on working gears by cutting, wherein the working gear and the cutting tool are driven in rotation at a predetermined speed ratio along axes oriented at an intersection angle. The flanks of the cutting teeth form edges having flank cutting sections arranged on the edges of a gap between two adjacent teeth and extend along a first contour line, and which as a result of an advance in the direction of the working gear engage in a cutting manner to produce teeth having a flank contour predetermined by the shape of the cutting edge. Each of the flank cutting sections is adjoined by a tip cutting section which extends along a second contour line in the region of the base of the cutting tooth gap, wherein the second contour line is curved such that at least partially rounded tooth tips are produced on the teeth.

An analog output driver is responsive to the controller output signal and configured to generate the sensor output signal at a first predetermined level or at a second predetermined level and a feedback circuit coupled between the sensor output and the digital output controller is configured to generate the digital feedback signal in response to the sensor output signal.

Abstract: A method for cutting teeth into working gears using a tool, the tool main part of which has a plurality of cutting teeth which are arranged about a rotational axis and which protrude radially from the tool main part, the cutting teeth forming an end face, two tooth flanks which point away from each other, and cutting edges. The cutting edges are formed from the tooth flank edges adjoining the end face. In a first method step, tooth gaps which form tooth flanks are produced in the working gear by means of the cutting edges using a machining process in a first position of the tool relative to the working gear, and in a second method step, the working gear tooth flanks produced by the cutting edges are fine-machined by an abrasive tool surface.
