Eyewear having a curved frame includes a protruding cover lens unit. The device includes a noise reduction three-dimensional look-up table and a noise reduction unit. On the surface of the substrate, strip-lines are disposed at an angle, being insulated with each other. The invention includes peptides derived from the IA-2 polypeptide by such a method, altered peptide ligands, and methods of therapy involving the use of altered peptide ligands. In order to set different deflecting positions, the disk segments can be fixed in different circumferential positions.
