A door latching mechanism for the door of an electric household appliance, in particular a washing machine, is described. For example, the control line can be deployed in a protected position along a stinger to reduce the potential for damaging the control line during installation, removal or operation. The processing module includes a substrate, an image sensor formed on the substrate for generating a plurality of pixel signals, a calculation unit formed on the substrate for calculating at least one motion vector based on the plurality of pixel signals, and a transmission interface formed on the substrate for serially outputting the motion vector. The polymer mixture is used in injection molding, injection blow molding or blow extrusion.
