APPARATUS FOR PERFORMING NON-CONTACT DATA TRANSFER BETWEEN TWO OBJECTS MOVING TO ONE ANOTHER AND FOR DETERMINING ANGULAR VARIATION

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 【課題】共通の回転軸を中心として互いに対して運動する２つの物体の間で非接触データ伝送を行うため及び角度変化を特定する。【解決手段】第１の電極を含む第１の電極担持体が第１の物体に設けられ、第２の電極を含む第２の電極担持体が第２の物体に設けられ、第１及び第２の電極担持体は回転軸の軸方向に離間して対向しており、第１及び第２の電極の間で電気的な結合を通じたデータ伝送が可能であるように第１及び第２の電極が配置されている。少なくとも１つの発光領域と少なくとも１つの吸光領域とを含む標識が第１の電極担持体に設けられ、第１の電極からペイロードを含む信号を第２の電極へ伝送するように構成された制御ユニットが設けられている。第２の物体に対して固定され標識を検出するように構成された光学センサを含む評価ユニットが設けられ、標識に基づいて第１及び第２の物体の間の角度変化を特定するように調整される。【選択図】図１
