  • Patent number: 9784811
    Abstract: A two-channel magnetic resonance tomography system is provided with a regulation circuit for an amplification system in order to be able to take into account different load situations of the MRI system in a flexible and efficient manner. It is thus possible to improve the MRI measurements greatly if the MRI system is set to the respective load situation beforehand by an idle state measurement. The adaptation may optionally also be carried out during the MRI measurement. Therefore, a multiplicity of completely different load situations may be taken into account in an optimized manner by the regulation circuit.

    Abstract: A smart electrochemical processing apparatus includes a reaction container, an electrode unit and a surface feature scanner. The reaction container has an electrolytic tank. The electrode unit has a first electrode fixed to the electrolytic tank and a second electrode rotatably positioned at the electrolytic tank. The surface feature scanner is positioned at the electrolytic tank. Before being put in the electrolytic tank for processing, a workpiece positioned at the second electrode is scanned with the surface feature scanner while being rotated by the second electrode. After surface feature data of the workpiece have been collected, various process parameters can be adjusted to thereby achieve satisfactory surface treatment of the workpiece.
