Abstract: In a method for operating an injection valve, in particular a fuel injector of an internal combustion engine of a motor vehicle, one component of the injection valve, particularly a valve needle, is disposed in a manner allowing movement relative to other components of the injection valve, and preferably is able to be driven at least partially by an actuator. A structure-borne-noise signal is detected by a structure-borne-noise sensor, and the structure-borne-noise signal is evaluated in order to infer an operating state of the movably disposed component.

Abstract: In a method for manufacturing a bar winding for the stator of an electric machine, in particular of a claw pole alternator for motor vehicles, resistance welding is used to form mechanically and electrically reliable and permanent connections in the winding overhang of the stator even with winding configurations that include four or more superposed conductor segments, and even with the very small amount of working space that remains for the necessary connections, using a minimum of production-related outlay. With a design, in particular, of four radially superposed conductor segments in the winding overhang, particularly advantageous configurations result in terms of the placement of the bar ends and in terms of the design of the welding electrodes.

Abstract: The invention presents a method and an apparatus for optimizing or monitoring or analyzing process sequences of an automated device, such that a visualization of the data sets is implemented by means of a display means 12a, b, c, with the use of at least one first and one second data set, in such a way that a visual cross-reference 15, 16 is created between data-set segments that are relevant to the process sequence. This allows the machine operator to recognize quickly those points in the process sequence where a need exists for intervention. Manufacturing costs can thereby be lowered, and product quality improved.

Abstract: To achieve a specifiable, and thus reproducible final pressure in at least one part of the brake circuit, the pump is first actuated for pressure buildup or pressure reduction when the valve is closed. When a first specified setpoint pressure is reached, or when a pressure threshold value is exceeded, the valve is put into an open position using a first actuation. After the pump is switched off, the actuation of the valve is modified in such a way that, during a specifiable time, a continuous change of the first actuation is undertaken all the way up to a second actuation, in which the valve assumes a holding position, particularly while taking into consideration the pressure difference which prevails at the valve.
