Abstract: The present disclosure provides a casing and a lens and relates to the technical field of optical equipment. The casing includes an outer casing provided with an accommodating hole and an inner casing accommodated in the outer casing and provided with a mounting hole. The outer casing is made of metal material, and a hardness of the inner casing is lower than a hardness of the outer casing, thereby the outer casing can meet the metal shape requirements of the lens. The relatively soft inner casing can solve the problem that a metal material cannot be tightly fitted with the lens group. The casing not only has advantages of metal profiles, but also can take a fitting structure with stacked outer diameters and a bumpy ridge fitting structure into account due to providing the relatively soft inner casing inside, which is more beneficial for lenses with high performance requirements.

Abstract: A method for selecting at least one connection pattern drivable by road users using a control device. Trajectory data are received from at least one area. On the basis of the received trajectory data, starting points and end points of drivable trajectories are determined. All the connection patterns between the starting points and the end points of the drivable trajectories are determined in the form of connecting lines. The determined connection patterns are filtered by at least one filter. Connection patterns remaining after filtering are compared with route profiles from the trajectory data. For each remaining connection pattern a number of route profiles which correspond to the connection pattern are counted. A connection pattern with the highest number of matching route profiles is selected. A control device, a computer program, and a machine-readable storage medium are also described.

The autonomous vehicle includes a plurality of sensor systems that generate a plurality of sensor signals, a notification system, and a computing system. The computing system determines that the autonomous vehicle is to execute a maneuver that will cause the autonomous vehicle to traverse a portion of a driving environment of the autonomous vehicle. The computing system predicts that a person in the driving environment is to traverse the portion of the driving environment based upon the plurality of sensor signals. The computing system then controls the notification system to output a first indicator indicating that the autonomous vehicle plans to yield to the person or a second indicator indicating that the autonomous vehicle plans to execute the maneuver prior to the person traversing the portion of the driving environment.
