Abstract: A method for operating a motor vehicle, wherein the motor vehicle is configured to execute at least one a driving maneuver that can be executed without a driver, wherein, before the driving maneuver is executed by a computing device of the motor vehicle, a check is made to determine that at least one admissibility requirement for the execution of the driving maneuver is met. The execution of an operator action required to start the execution of the driving maneuver, executed by a user of the motor vehicle positioned outside the motor vehicle, is detected, or the absence thereof up to the present time is detected. The execution of the operator action can be detected by a monitoring device connected to the computing device, and/or based on a transmission of data describing the execution of the operator action to a communication device of the motor vehicle connected to the computing device.

Abstract: A saw chain includes connecting links and drive links that are mutually connected by rivets in an articulated manner about rivet axes. The rivets project through at least one rivet opening of one connecting link and through a rivet opening of a drive link. At least one rivet has, on one end face thereof, a depression having a depression edge and a depression base surrounded by the depression edge. The distance of the depression edge from a central plane of the saw chain increases at an increasing radial distance from the rivet axis. The distance (e) of the base from the central plane does not increase at any point of the base at an increasing radial distance from the rivet axis. A greatest distance (a) of the base from the rivet axis corresponds to 50% to 100% of half the core diameter (d) of the rivet.

Abstract: The refinement of a lower-pel resolution motion estimation vector is made more effective by preceding the actual refinement with a determination of a context out of a set of context candidates based on coding costs of a set of lower-pel resolution vectors within a neighborhood of the lower-pel resolution motion estimation vector, wherein each context candidate is associated with a ranking among a set of higher-pel resolution candidate vectors surrounding the lower-pel resolution motion estimation vector. The actual refinement of the lower-pel resolution motion estimation vector to obtain the higher-pel resolution motion estimation vector may thus use the ranking associated with the context determined: sequentially arranged accordingly, the set of higher-pel resolution candidate vectors may be tested sequentially.

Abstract: A handheld work apparatus has a tool and a brake assembly for the tool. The brake assembly has an actuating element which acts on a brake element of the brake assembly. The actuating element is movable between a fixed position wherein the tool is not braked, and a released position, wherein the brake element brakes the tool. To fix the actuating element in the fixed position, an electromagnet is provided. The electromagnet interacts with an anchor on the actuating element. The anchor is mounted via a pivot joint on an anchor pin to be pivotable about a pivot axis. A guide includes a guide part connected to the anchor and a guide part connected to the yoke, wherein, in the fixed position of the actuating element, the guide parts guide the anchor relative to the yoke in a transverse direction of an outrigger of the apparatus.

Abstract: An electromagnetic valve has a valve chamber which has an inflow opening for supplying a liquid and an outlet for discharging the liquid. The valve includes a valve seat and a valve member that is assigned to the valve seat. The fluidic connection between the inflow opening and the outlet of the valve is interrupted when a valve seat is closed by the valve member. The valve member is held on an armature plate which is moved by an electromagnetic drive unit toward an end stop which is formed by a first stop surface. In order for the operative capability of the valve to be guaranteed in the case of wear on the end stop, the armature plate is assigned a second stop surface which upon a predefined wear on the first stop surface forms a downstream end stop.
