Abstract: One example method involves obtaining a plurality of scans of a field-of-view (FOV) of a light detection and ranging (LIDAR) device disposed inside a housing. Obtaining each scan of the plurality of scans comprises: transmitting, through a plurality of sections of the housing, a plurality of light pulses emitted from the LIDAR device in different directions toward the housing; and detecting a plurality of returning light pulses comprising reflected portions of the transmitted plurality of light pulses that are reflected back toward the LIDAR device. The method also involves detecting an obstruction that at least partially occludes the LIDAR device from scanning the FOV through the housing based on the plurality of scans.

Abstract: A position-measuring device and a corresponding method for measuring an absolute position includes a material measure having a first binary code and a second binary code and a sensor device that scans the first and second binary codes. The sensor device scans the first binary code, which has a first number of code words, each having the same code word length. The second binary code of the material measure forms a portion of the first binary code and has a second number of the code words that can be mapped onto the first binary code.

Abstract: A method for simulating different traffic situations for an autonomous or semiautonomous test vehicle. The method includes the simulated driving of the test vehicle through a simulated road network, and the simulated randomized driving of other vehicles through the simulated road network. The method also includes the capture of vehicle driving parameters. Further according to the method, there is a determination of whether a predefined traffic situation is satisfied by the test vehicle and at least one of the other vehicles, the at least one other vehicle being within a test zone around the test vehicle. Where the predefined traffic situation is satisfied, randomized driving of the at least one other vehicle can be stopped, and the at least one other vehicle can be made to perform a predetermined driving maneuver. The predetermined driving maneuver can provoke a reaction by the test vehicle.

Abstract: An expansion anchor includes a bolt as a first element and an expansion part as a second element. One of the two elements has a first rib running longitudinally along the bolt and the other of the two elements has a first groove running longitudinally along the bolt, where the first rib engages in the first groove. The one of the two elements has a second rib running longitudinally along the bolt and the other of the two elements has a second groove running longitudinally along the bolt, where the second rib engages in the second groove. A first catch of a snap connection is formed between the first rib and the first groove and a second catch of the snap connection is formed between the second rib and the second groove, where the first catch and the second catch hold the expansion part radially to the bolt.
