Abstract: A single- or double-sidedly bonding adhesive-sheet strip having a self-adhesive composition comprising a) at least one elastomer, at least one type of polybutadiene block copolymer being used as an elastomer, b) at least one partially hydrogenated hydrocarbon resin having a softening temperature of at least 90° C., c) at least one additional hydrocarbon resin, a terpene phenol resin and/or a colophonium resin having a softening temperature of at least 90° C., d) an optional soft resin, and e) additional additives as applicable.

Abstract: A vehicle oxygen indication system that includes at least one oxygen source, and a plurality of oxygen assemblies. Each oxygen assembly includes a hose, a switch, a mask, and a flow indicator. The hose includes a lumen through which oxygen can flow from the oxygen source to the mask. The switch is switchable between a normal state when oxygen is not flowing from the oxygen source to the mask and a flow state where oxygen flows to the mask. When the switch is in the flow state, the flow indicator is switched from a static state to an indication state.
