A convertible has a top which can be opened and can be put away and which has a rear window frame and, when the top is closed, at least one surface bow situated in front of said rear window frame in the direction of travel. Provided are a process for producing a coating film excellent in such weather resistances as gloss retainability, resistance to discoloration and resistance to cracking necessary for long-term outdoor uses, and a coating material which gives the film. Cells are selected dependent upon the associated delays. Redirection is accomplished by transmission from the storage manager to a switch redirection commands that contain old and new address data. In addition, the materials of the carrier, the base board, and the diffraction grating are selected with respect to their thermal expansion coefficients such that the temperature drift of the spectrum is substantially compensated for the entire measured spectrum. The contact points provide electrical communication between NFC circuitry of the mobile device skin and the smart card within the mobile device.
