An antenna includes a dielectric material having i) a first side opposite a second side, and ii) a conductive via therein. The storage media interfaces are separately used to contain and connect a storage medium and the controller is electrically connected with the storage media interfaces for providing a data transmission channel to the storage media according to a detecting signal, and outputting an indicating message to the processor base system when another detecting signal produced. The first encapsulation layer is encapsulated in between the transparent layer and the layer of solar cells. The guarded item of the user-interface screen served to the remote client may have an altered appearance to the remote client andor may be inoperable to the remote client. The invention also includes compositions comprising DHEA or a derivative thereof and a second drug.
