The present invention concerns deodorant products based on a synergistically active antimicrobial mixture of picolinic acid and a peroxyl species or equivalent source thereof. A chassis ID identifies a chassis type. The distributing valve is in an open neutral position and can be displaced, electrically or electrohydraulically, from said neutral position into the direction of the second switch position thereof. This produces a reliable passivation which is particularly suitable for capacitively measuring fingerprint sensors. A simulation system utilizing the method receives update information such as control signals, over an input interface and includes instructions on a storage media and a processor for calculating the shape of the thread and outputting the result over an output interface.
