A semiconductor device includes an active element structure that is formed on a semiconductor substrate and has a connection region formed in the surface of the semiconductor substrate. A light source disposed on the mobile device plug of the vehicle charger connects to either an external or an internal power supply to provide a beam of light used to illuminate the mobile device. In addition, the invention relates to a mounting system for carrying out the method. Suitable design of the additional current paths compensates for deviations of the fringe field from its design specification, due to deviations of coil parameters from their design values. A plurality of the other of conductive word lines or conductive bit lines is provided from said plurality of self-assembled block copolymer lines to form individually programmable junctions comprising said metal oxide-comprising material where the word lines and bit lines cross one another. The client-side device establishes the first secure communication channel by providing a certificate impersonating the server device to the client device.
