Abstract: The invention relates to the positioning of an additional photo receiver in addition to the known laser sensors for detecting double parts during transport and during the loading of machines, which are situated opposite each other. The additional photo receiver receives the laser beam from a laser sensor located opposite, exactly when there is no material in the measuring gap and the two laser sensors are precisely aligned. This arrangement makes it possible to improve the measuring process and the analysis of the measurement, and thereby increases process reliability during the monitoring of transport and the loading of machines.

Abstract: There is provided a method for the automated testing of software, which has a graphic user interface. With at least one graphic editor, at least the dynamic and the semantic behavior of the user interface of the software is specified. Test cases are generated by a test case generator software using the thus specified behavior of the user interface, which are then executed by a software for automatic running test running either immediately or in a later step.
