DEVICE FOR THE CONTACTLESS TRANSMISSION OF DATA AND FOR DETERMINING ONE CHANGE IN AN ANGLE BETWEEN TWO OBJECTS MOVING RELATIVE TO EACH OTHER

PROBLEM TO BE SOLVED: To provide an apparatus for performing non-contact data transfer between two objects moving to one another around a common rotation axis and for determining an angular variation.SOLUTION: A first electrode carrier including a first electrode is provided on a first object, a second electrode carrier including a second electrode is provided on a second object, the first and second electrode carriers face each other separately in a rotation axis, and the first and second electrodes are arranged so as to enable data transfer through electrical coupling between the first and second electrodes. An indicator including at least one light emission region and at least one light absorbing region is provided on the first electrode carrier. A control unit is provided which is configured to transfer a signal containing payload from the first electrode to the second electrode. An evaluation unit is provided which includes an optical sensor fixed to the second object and configured to detect the indicator. The evaluation unit is adjusted to determine an angular variation between the first and second objects based on the indicator.SELECTED DRAWING: Figure 1
