Powder clearcoat dispersions preparable by adding a secondary acrylate copolymer dispersion in liquid andor powder form to a powder slurry during andor after its preparation; and the use thereof for producing clearcoat finishes, especially as part of multicoat color andor effect finishes. Functional chips each have a signal processing circuit for executing auxiliary signal processing different from that of the signal processing circuit; and one or a plurality of signal transmitting circuits for transmitting signals between the signal processing circuit and the signal transmitting circuits. The capillaries transmit statically-retained fluid that is in contact with the upper surface of the protrusions. In addition, the unified messaging system can automatically determine, based on a first selected feature, if one or more message types should be used. Coated magnetic milliparticles and magnetic microparticles are useful as component of composites that are applied to electrodes to alter electrochemical fluxes across those electrodes, as well as to alter chemical reactions on surfaces of those electrodes, when magnetically susceptible reactions occur there.
