The present invention is a decorated polymer sheet, said polymer having a modulus of from about 1000 psi to about 20,000 psi, as determined according to ASTM D 638-03, wherein at least one of said surfaces of said sheet has disposed thereon an image and an adhesive composition, and at least a portion of said adhesive composition is in contact with said image. Some implementations are particularly well suited for automatically playing both sides of a dual-sided optical disk. After converting the user’s query from speech to text, a 2-step algorithm employing a natural language engine, a database processor and a full-text SQL database is implemented to find a single answer that best matches the user’s query. In the shift position changing mechanism, the first and second clutches are engaged or disengaged, thereby changing the shift position among forward, neutral, and reverse. A mobile communication device includes the fuel cell system. An inner platform is coupled to a root section of the airfoil, with a curvilinear gusset extending along a lower surface of the inner platform, opposite the root section.
