Abstract: A variable valve drive (1) of an internal combustion engine is provided which is used to actuate a gas exchange valve (5). Displacement thereof takes place via a cam (7) generated lift and via a lift generated by a piston (14, 32) of a hydraulic force applying device (4a, 4b), which is superimposed on the cam lift and which is independent thereof. The hydraulic force applying device is connected to a hydraulic fluid line (S-P) which provides an adjustable hydraulic pressure medium and includes a pressure chamber (24a, 24b) which is limited on one side by the piston (14, 32), in addition to a hydraulic valve lash compensation device (23a, 23b) which includes a working chamber (22a, 22b) which is radially defined by a housing (13a, 13b). The housing (13a, 13b) is also used to radially define the pressure chamber (24a, 24b).

Abstract: In a method and a system for supporting the evaluation of a picture of a patient's eye the picture is displayed on a screen. An image-processing algorithm from a number of image processing algorithms is selected due to a preliminary diagnosis selected from a number of diagnoses which are related to diabetes. Each image-processing algorithm of the number of image processing algorithms is associated with a diagnosis of the number of diagnoses and is designed to search for a pattern which is specific to the respective diagnosis. The selected image-processing algorithm then is applied to the picture and a pattern which is detected by the selected image-processing algorithm is marked on the screen in the picture.

Abstract: The present invention relates to a method and a corresponding plant for producing a fibrous web, in particular a paper web, paperboard web or tissue web. The formation of the fibrous web is defined online as a controlled variable and is held at a preselectable set-point level by way of an automatic formation control system.

Abstract: In a method and system for retrieving a medical image from a data base, an image processing algorithm is applied to a first medical image. The result of the applied image processing algorithm to the first medical image is compared with a plurality of results being stored in a data base. Each result of the plurality of results is the result of the image-processing algorithm being applied to each medical image of a plurality of medical images which is stored in the data base. Then, a second medical image belonging to the plurality of medical images is determined and retrieved from the data base, wherein the relevant result is comparable to the relevant result related to the first medical image.

Abstract: The present invention relates to a twin wire former in a machine for the production of a fiber web, especially a paper or cardboard web from at least one fiber stock suspension, including a vertical twin wire segment having two wires running over a peripheral area of a turning element, especially a guide roll whose surface is preferably not equipped with suction and is smooth or substantially smooth; and in that at least one separation element, such as a transfer suction box is provided indirectly or immediately following the guide roll that separates the top wire from the bottom wire on which the fibrous web is supported.

Abstract: In a method and system for monitoring the course of therapy administered to a patient, at least one information value that requires a therapeutic and/or diagnostic measure and that is a direct or indirect measure of the course of the therapy is registered continuously or in time intervals, and at least one comparison value, to be compared to the information value or to a calculated value determined based on the information value, is allocated to the information value. An alarm signal is emitted given an impermissible deviation of the information value or of the calculated value from the comparison value and is detected in the course of the comparison. The comparison value is varied dependent on the course of the therapy and is adapted to the course of the therapy, the adaptation of ensuing automatically or by means of an authorized person or entity.

Abstract: The invention relates to a method for analyzing image processing procedures, in which unprocessed original image data is stored, stored original image data is retrieved, retrieved original image data is processed, the individual processing steps during the processing of the image data are in some instances stored together with the respective processing step parameter values, and the processed image data is stored such that it can be assigned to the processing steps stored during its processing and in some instances processing step parameter values. According to the invention the processed image data is analyzed statistically and the result of the statistical analysis is stored such that it can be assigned to the stored processing steps and in some instances processing step parameter values. The original image data is optionally included in the statistical analysis of the processed image data.

Abstract: Identification information is overwritten onto a defined region of a medical image or examination data. Original data formerly occupying the overwritten region is saved and stored on a server, and associative information identifying the storage location of the original data is determined and optionally written into the defined region. The original medical image can be reconstructed by locating the stored original data from the associative information and placing the original data back into the defined region.
