The present invention is related to an aqueous cleansing composition for keratin fibres, especially human hair, comprising at least one amino acid surfactant, and a cationic polymer. In this case, the processors of adjacent processor units have intermediate connections for interchanging data. The antenna platform also includes a ball joint for supporting the center of the antenna, enabling a reduction in the requirements of the two motors. The invention also concerns a method for producing the thin film. In alternative embodiments a post detection correction algorithm may be added to improve performance. The toner particles further include 0.
