Improved stent configurations exhibiting limited recoil, resistance to compression and improved longitudinal flexibility. Information is transferred between a first node and one of the SSL relays where the transferred information is related to communication between the first node and a second node. Mechanical and motorized dispensers may be used with the inventive spout fitment. The radio waves are detected by a radio receiver in the evacuation guide. When the occupant is restrained by the shoulder-protecting inflatable portion, the valve body elements are flexed and separated from each other by external force applied following the restraining, thereby permitting flow of inflation gas at the internal opening. The shield can include a magnetic portion that is detected by a first sensor on the apparatus.
