Abstract: An agricultural work machine comprising a driver assistance system. The driver assistance system is configured to automatically monitor and set work parameters and quality parameters of the agricultural work machine and is assigned a process model comprising performance maps. The optimization method implemented by the driver assistance system is designed as a map control and generates optimized work parameters as manipulated variables. The driver assistance system determines the quality parameters of the agricultural work machine depending on the optimized work parameters. The process model comprises a dynamic non-linear process model in such a way to comprises a static process model component and a dynamic process model component. At least the manipulated variables in the static process model component execute through an optimization step and, in the dynamic process model component, through a control loop structure.

Abstract: A method is provided for testing or calibrating a pressure sensor of a plurality of pressure sensors formed in a wafer, wherein the pressure sensor has a pressure-sensitive portion and a signal output. The method includes a step of connecting the pressure-sensitive portion of the pressure sensor to a fluid line in a pressure-tight way, a step of applying a predetermined pressure to the pressure-sensitive portion of the pressure sensor via the fluid line and a step of receiving a signal from the signal output of the pressure sensor.

Abstract: A method and a device for separating flat, sheet-like elements from a stack of such elements, in particular, from a stack of unexposed printing plates that will be automatically loaded into a printing plate recorder. When the upper or front element in the stack is being separated from the stack, an edge area of this element is curved up in some way.
