Embodiments of an apparatus including a color filter arrangement formed on a substrate having a pixel array formed therein. Accordingly, the general driving operation is monitored with the aid of a vehicle’s own sensor system with respect to a maintenance state and, if a maintenance state is established, the admissible value range be automatically extended or at least one operating parameter is ignored during monitoring. A rotor is received in the housing coaxially with the smaller-diameter cylinder and comprises at least two segmental rotor parts provided with annular rotor covers. A current sensor may be utilized to count, discriminate or characterize the molecules as they interact with the nanopore.
