A method for forming a dual damascene feature is provided. Accordingly, a driver and a passenger on an assistant driver’s seat can see an outer side of a vehicle through the visibility adjusting section, and a suitable light can be taken into the vehicle. A PPAN matching process uses the PPAN elementsPPAN chain to search for structured documents that match the PPAN chain. The oblique-collision arresting section is a high-pressure section which has a higher internal pressure than the main bag section when inflated. The assembly may include one or more additional print heads.
