A system of producing digital portraits and associated methods are provided. The transfer device is arranged at a distance adjacent to a housing part so as to be rotatable about a vertical axis and, to alter the height setting, elevatable about a horizontal axis. This remote indicator can be in the form of a warning light or in the form of a remote display with a receiverantenna communicating with a transmitter coupled to a pressure transducer which monitors tire pressure. Moreover, projections are provided in the terminal area such that heights of the projections are equal to or more than those of the thin-film transistors. The second conductive pattern is connected to the via on the second surface.
