A security system for powering and displaying a handheld electronic device includes a stand assembly mounted to a support and a housing removably mounted on a top portion of the stand assembly. In one aspect, the light emitting diode has a carrier, an active layer structure of III-nitride type materials, and a photonic crystal structure of III-nitride type materials. The transmitter is operably coupled to convert outbound parallel data from the network interface processor into serial transmit data. These methods are helpful in the production of energy while utilizing carbon dioxide and carbon monoxide gases and limiting the landfill of organic materials. The data packets stored in a buffer are ignored if the target recipient is another mobile unit. In some embodiments, the molecules attached to the surface may include thiol moieties, by which the molecule can become attached to the surface.
