Abstract: The invention relates to a method for checking a compatibility of a functional module for an installation for process automation. An input specification is provided for an input interface of the functional module, the input specification indicating for an input signal all input values that the functional module respectively accepts as valid. An output specification is provided, the output specification indicating for an output signal of the functional module all output values that the functional module provides as intended when the input specification is fulfilled. Operation of the functional module on the installation is preceded by an analysis device checking whether the functional module produces, for each input signal produced on the input interface in accordance with the input specification, the output signal on an output interface in accordance with the output specification. When an output value of the output signal violates the output specification, a module error is signaled.

Abstract: A communications network and method for operating the communications network that includes ring devices that are networked to one another in a ring topology, where the ring devices participate in a ring redundancy process in which an administrating ring device regularly sends test packets over the communications network, which received in sequence by other ring devices and successively forwarded by these devices back to the administrating ring device so as to detect faults in the communications network, where a transmission delay of a test packet along the ring topology because of interfering packets within the ring topology is prevented by synchronizing the ring devices and processing at least parts of a data traffic schedule in accordance with the 802.1Qbv standard in the ring redundancy process applied, and where transmission of the test packets is scheduled and controlled such that the packets are forwarded to the ring devices substantially without delay.

Abstract: A method is disclosed for creating a motion correction for PET data acquired by a PET system from a volume segment of an examination object. The method includes acquisition of MR data within the volume segment by the magnetic resonance system; and determination of a motion model of a motion within the volume segment as a function of the MR data. The motion model, as a function of a respective motion state of the motion, provides a correction specification for PET data which is acquired during this motion state. During acquisition of the MR data, specific MR data is acquired in the center of the k-space or of a straight-line segment which passes through the center of the k-space. The MR data determined is converted by a mathematical function into one value, as a function of which the respective motion state is determined.

Abstract: There is described a method and a system allowing the use of at least one resource of a first automation system in at least one second automation system, whereby the resource is made available by the first automation system and an identification characteristic is used for the unique identification of the resource in the at least second automation system. A user is enabled to navigate in a simple manner between the application locations of originator and user of a resource. This is achieved by the fact that the use of the resource of the first automation system in the at least second automation system is mapped as a bilateral reference in each case between the automation systems and is stored in each case in a storage area in the automation systems, whereby the bilateral reference also contains application locations of the resource in the respective automation system.

Abstract: In situations where first equipment of a first technical installation could hitherto not be monitored based on condition data of the first equipment from the first equipment alone, it is proposed that a first sensor measures first condition data of the first equipment and that art additional sensor measures additional condition data of an additional equipment of an additional technical installation. The first condition data and the additional condition data are transmitted to a sorting unit and processed by the sorting unit into a ranking list. A corresponding sorting unit and a system as well as a corresponding computer program and a computer program product are also disclosed.

Abstract: An apparatus for processing a gas stream and especially for processing a flue gas stream, includes a scrubbing apparatus for removing harmful substances from the gas stream by means of a scrubbing medium, and a separation apparatus which is connected downstream of the washing apparatus and comprises an absorber and a desorber for separation of carbon dioxide from the gas stream by means of a scrubbing medium. In this context, the scrubbing apparatus and the separation apparatus are set up to use the same scrubbing medium. A process uses the same scrubbing medium both for pre-purification of the gas stream in a scrubbing apparatus and for separation of carbon dioxide in a separation apparatus.

Abstract: A method reconstructs a reconstruction data set containing virtual X-ray images of projection images of a target region recorded with an X-ray device. The projection images being recorded at different positions of an X-ray source along a scanning trajectory. The method includes defining an imaginary position of the X-ray source for each virtual X-ray image. For each virtual X-ray image and each pixel to be reconstructed in the X-ray image a virtual beam section, covering the target region, of the path between the imaginary position of the X-ray source and the pixel is defined. For each projection image, an integral is determined from the relationships between the forward projection and the filtered back-projection by re-parameterizing. A projection value of the virtual X-ray image from the integrals determined is combined.

Abstract: Method and a system for transmitting data in a switchable data network. To improve the transmission of data having different priorities in the switchable data network, telegrams are assigned priorities, with said telegrams (70-77) in each case having a beginning and an end. Data telegrams assigned a first priority are sent during a first phase from first users to second users, with the first phase being characterized by a defined receive time of the end of one or more of the data telegram at one or more second users.

Abstract: The present invention pertains to a method and device for recognizing distribution data on postal packets, small packages or journals during the automatic mail processing, especially to systems by which the automatic handwritten adress recognition process is supplemented and improved by video coding. The distribution data are written on various backgrounds, including pattern backgrounds. After a first unsuccessful optical character recognition attempt, the complete surface of the postal packet is displayed with a grid on a videocoding-screen. Once a picture segment has been selected which contains a larger part of the distribution data, the operator submits an image portion containing said picture segment and the adjacent areas to a new optical character assessment, while making sure that all the data area is included in the image portion.
