Abstract: A device for detecting the position of an object in a machine tool includes a camera configured to provide an image of the object and an object carrier to which the object is connected and whose position within the machine tool is known. A first processing unit is configured to identify a position of the object relative to the camera based on geometric features of the object which are obtained from the image. A second processing unit is configured to identify a position of the object carrier relative to the camera based on geometric features of the object carrier which are obtained from the image. A third processing unit is configured to determine a position of the object relative to the object carrier from the identified positions of the object and the object carrier relative to the camera.

Abstract: A method for dynamic memory management that includes determining a priority of a requesting program portion and, based on the determined priority of the requesting program portion, either allocating a memory area in real time to the requesting program portion or allocating a memory area not in real time to the requesting program portion.

Abstract: A method and apparatus for monitoring a safety condition of a device, receive data from a plurality of operating-state detectors of the device selected on the basis of a specific configuration of the device to signal dangerous operating conditions of the device. Furthermore, to eliminate the need to completely redesign a safety monitoring program in response to modifications or expansions of the device, all the safety parameters are stored in one memory. The use of an exchangeable memory further simplifies modification of the system. A specific identifier is employed to rule out the use of an incorrect memory and a check sum for the memory contents allows detection of any unauthorized change in the memory contents.
