Abstract: An AC/DC adapter in which an AC to DC converter is incorporated in a multiple outlet wall adapter. The AC/DC adapter includes at least one standard AC plug receptacle and at least one DC receptacle. Electronic devices which require DC power can be plugged into to the AC/DC adapter by a power cord having a universal DC plug at one end and a connector or plug specific to the make and/or model of the electronic device at the other end. The universal DC plug corresponds with the DC receptacle provided on the AC/DC adapter. The adapter may be formed as one integrated unit or as a modular assembly which includes an AC module and a DC module. In the assembly, the AC and DC modules are constructed so that they can be fitted together and used as one conveniently sized unit, but modules can also be used independently of the other.

Abstract: The smart card according to the present invention includes a first integrated electronic module on one surface and another integrated electronic module on the opposite surface of the card, whereby the card is merely flipped over and reinserted into the electronic device to change applications or functions. The two integrated electronic modules provided on opposing surfaces of the card may be formed as two separate chips each embedded on one side of the card, or as one chip having exposed contact terminals on both faces of the card, depending on the size of the chip(s) mounted in the card. Alternatively, two integrated electronic modules can be both provided on the same surface of the card, in which case the card is rotated 180° to place the desired integrated electronic module in contact with the contact interface in the device to access the desired application or function.
