Abstract: A shaft current collector for a shaft assembly has a shaft and a machine part surrounding the shaft. The shaft current collector has an electrically conductive ring for arrangement on the shaft so as to electrically contact the same. The ring has an engagement recess which is arranged so as to extend axially relative to the central axis of the ring. A blocking element can be secured on the machine part relative to the shaft. When the shaft current collector is in the installed state, the blocking element engages into the engagement recess of the ring such that, as the shaft rotates, a rotation of the ring is restricted by the blocking element while the ring is electrically conductively contacted by the blocking element. A shaft assembly may have such a shaft current collector.

The detection model identifies two or more mentions from the unstructured NL text and a logical position of the mentions. The detection model further identifies a sequential position for each of the mentions and attaches a sequential position identifier. A pattern of rules corresponding with the annotated NL text is identified and applied to the annotated NL text, and one or more facts embedded within the annotated NL text are extracted and converted into structured data.
