A CPU of an image display apparatus transmits user manipulation to an input unit to a wireless unit of a data processing apparatus through a wireless unit, and a CPU of the data processing apparatus processes corresponding to the user manipulation. These composite materials in particular find their application in devices containing said compounds andor active materials, such as electrochemical devices and batteries, in particular lithium batteries. The outputs of the MUX module may be coupled to the plurality of antenna elements, respectively, for selecting at least one active antenna element at a given time from among the plurality of antenna elements during a scanning operation. A third adherent layer, formed of the second metal, is selectively covering leadframe areas intended for attachment to external parts and has a thickness suitable for such attachment. In certain embodiments, the amorphous carbon layer includes at least about 35% sp3 carbon-carbon bonds, more preferably at least about 70%, and most preferably at least about 80% of the sp3 carbon-carbon bonds.
