Abstract: A computer-implemented method for operating a technical device with the aid of a multi-dimensional characteristic map. The characteristic map is defined by data points, to each of which a characteristic field value is assigned. For reading out the characteristic map, an output value is determined, as a function of an input variable point to be evaluated for the technical device, with the aid of one-dimensional basis functions, which are assigned to each dimension of a data point. The function values of the one-dimensional basis functions respectively have a monotone curve to a neighboring data point, which has the function value 0, and are outside of the neighboring data point 0. The technical device is operated as a function of the output value.

Abstract: A central gateway controller (100) for managing data which is transmitted via a vehicle electrical system of a vehicle is provided. The gateway controller includes at least one central communication server, ZKS, (110) including at least one central information store, ZIA, (120) for centrally storing data, which is transmitted via the vehicle electrical system, and at least one communication module (130, 132, 134, 136) for transmitting data between the ZIA and at least one bus system (160, 162, 164, 166) belonging to the vehicle electrical system. The gateway controller can store the data transmitted via the communication module in the ZIA in uniform data sets. The gateway controller is thus not just used to route messages between different (message) producers or generators and (message) consumers or loads in the vehicle electrical system but is also capable of storing the data to be exchanged in the ZIA in a uniform format.

Abstract: A screen bar for a bar screen may comprise a steel composite sheet having at least three steel layers: a top layer, a core layer, and a bottom layer. The top, core, and bottom steel layers may be interconnected by roll cladding in a non-releasable manner. In some examples, the core steel layer may have a higher deformability than the top steel layer and the bottom steel layer. Likewise, the top steel layer and the bottom steel layer may have higher hardnesses than the core steel layer. Such screen bars have extended service life and can be manufactured more cost effectively, amongst other benefits. Methods for manufacturing such screen bars may involve a variety of steps including hot rolling and/or heat-treating.

Abstract: A method for avoiding a rear-end collision between a first vehicle and a second vehicle, in which a distance value is initially read in, which represents a distance, which is detected by a distance sensor of the first vehicle, between the first vehicle and the second vehicle. In particular, the first vehicle is located ahead of the second vehicle in a travel direction of the second vehicle. Using the distance value, a control signal is thereupon generated for controlling the first vehicle to avoid the rear-end collision.
