A contact roller system of a winding machine for thin strip material has a shaft and pivot levers arranged in a row adjacent to one another on the shaft. Multiple digital sources are respectively connected to stimulate multiple respective first ends of multiple respective nets of interest. In response, the UE unilaterally takes action to prevent the valid authentication that is not a mutual authentication from being used to authenticate with a radio network operating with a second RAT that utilizes mutual authentication. The automatic post-processing method according to the invention safeguards the validity of the result. The sensor system is configured to generate sensor data.
