The invention relates to a device and a method for reducing the number of analog inputs at a control device (). It is proposed that at least two physical signals, which are different from each other, are transmitted at an analog input of the control device ().

Device and method for reducing the number of analog inputs at a control device

A method for adjusting a laser beam includes, following passage of the laser beam through a beam-shaping device, measuring, via a detector of a detector device, a beam profile of the laser beam. The method further includes determining a beam quality property of the laser beam based on the measured beam profile and altering an adjustable optical unit for modifying at least one property of the laser beam prior to the entry into the beam-shaping device. For adjusting the laser beam, the adjustable optical unit is altered based on the determined beam quality property.

A method for vehicle electrical system diagnosis by means of a regulator, which is configured to regulate the voltage supplied by a generator via a converter for a vehicle electrical system of a vehicle by outputting an output signal, wherein the method comprises the following steps: detecting an output signal by way of a control device, ascertaining an instantaneous power output at the vehicle electrical system on the basis of the detected output signal, and analyzing the ascertained power output for diagnosis of the vehicle electrical system and at least one electrical consumer which is connected to the vehicle electrical system.

The invention relates to a method for determining at least one beam propagation parameter (M, w, &#x3b8;, z) of a laser beam, comprising: directing the laser beam through a lens arrangement towards a spatially resolving detector, imaging the laser beam at a plurality of different focus positions (F, . . . ) relative to the spatially resolving detector by adjusting a focal length (f, . . . ) of the lens arrangement, and determining the at least one beam propagation parameter (M, w, &#x3b8;, z) by evaluating an intensity distribution (l(x,y)) of the laser beam on the spatially resolving detector at the plurality of different focus positions (F, . . . ). The method comprises adjusting the focal length (f, . . . ) of the lens arrangement by arranging lens elements (A, . . . ; B, . . . ) having different focal lengths (f, . . . ; f, . . . ) in a beam path of the laser beam.
