Abstract: A system includes water-bearing household appliance which includes a controller apparatus for executing a treatment program from a plurality of treatment programs, with each of the treatment programs being defined by program parameters. A memory device stores treatment programs in the form of a N-dimensional matrix, with the treatment programs being associated with matrix elements of the matrix respectively. Each matrix element is determinable by a respective one of defined N-dimensional input vectors. An input captures a user input to change a program parameter, and a selection unit selects one of the defined N-dimensional input vectors as a function of the captured user input, with a determining unit determining a matrix element from the matrix as a function of the selected input vector. The controller apparatus carries out the treatment program associated with the determined matrix element.

Abstract: A method for operating a vacuum gripping device including a suction gripper unit, which is provided with at least one suction gripper. The suction gripper unit can be connected, via a control valve device connected to it, selectively to a vacuum source or to a positive pressure source generating an ejector pulse in the suction gripper. The ejector pulse is generated as a function of the actual pressure established in the suction gripper unit after its connection to the positive pressure source. A vacuum gripping device suitable for executing this method and including a pressure measurement device for detecting the actual pressure and an electronic control unit used for controlling the control valve device and communicating with the pressure measurement device.
