Abstract: A pressure-resistant fluid encapsulation has a cast wall made of a first metal. The cast wall is provided with a non-manual mechanical reinforcing element. The reinforcing element is formed of a different material from the first metal of the cast wall.

Abstract: A method is provided for diagnosing a monitoring system of technical equipment, the technical equipment having at least one unit, the at least one unit having a plurality of components of an identical or similar type. The method detects an error report for a defective component, associates a time stamp with the detected error report and/or with the defective component, and associates a location stamp with the detected error report and/or with the defective component. The method further performs an error diagnosis by checking whether the detected error report or a similar error report is logged for at least one other component having a location stamp identical or similar to the associated location stamp and/or having a time stamp identical or similar to the associated time stamp.
