An airbag, in particular a side airbag, has a primary chamber, which can be connected with a gas source, and at least one secondary chamber which is connected to the primary chamber. The device can be used for metal-enhanced fluorescence of fluorophores positioned above the metallic particles that can be readily applied to diagnostic or sensing applications of metal-enhanced fluorescence. The \u03b1-ketoacid can be formed using a novel sulfur reagent. The second synchronizing information is output from a second display controller and indicates a second display command is received. The connection on the second line is associated with one of the rotating switches, and the connections of the third and fourth lines are associated with the other rotating switch.
