Block copolymers can be self-assembled and used in methods as described herein for sub-lithographic patterning, for example. Said interaction unit, while interacting with a sensor system for detecting a respective physical-spatial position andor orientation of the interaction unit, serves to generate and transfer position data inside andor to the VR graphics system. The self organizing heap reorders the packets based on packet passing rules. The photoresist composition further contains an acid sensitive imaging polymer. Thereby, an influence on the main communication system due to the addition of the sub-communication system is reduced, so that a multi mode communication depending on the battery voltage can be efficiently carried out without any unpredictable situation for a user to occur. The appropriate desiccant dispensing nozzle is automatically selected andor the distance between the desiccant dispensing nozzle and the elongated spacer frame member is automatically determined based on a property of the spacer frame member, such as the width of the spacer frame member.
