Disclosed is a method for producing resin particles, which can impart a desired function to the surface of resin particles efficiently and simply. The electrical-plug-and-socket connection includes an electric line region and exactly one one-piece plug contact molding. The third membrane, which is preferably positioned between the two electrically conducting membranes need not be conducting, but defines two emergent cavities within the module. The rotation guide arrangement comprises a first guide element having a first guidance surface and a second guide element having a second guidance surface which cooperates with the first guidance surface. In addition, the collector region of the first transistor type or both transistor types is laterally delimited by the flat field-insulating regions. An antenna verification unit of the wireless receiving apparatus verifies a weight vector added to at least one of a signal sent from the first antenna and a signal from the second antenna by the wireless transmitting apparatus based on feedback information from the wireless receiving apparatus.
