The present disclosure provides a light emitting diode package, which includes a first substrate with electrodes disposed on a top thereof and a second substrate with an LED chip disposed on a top thereof. Block coding the plurality of symbols may include space-code, space-time andor space-frequency encoding the plurality of symbols. Address information associated with the computing device is used to form the logical connection with the computing device in accordance with the instruction. The scintillation device includes a dielectric gas inside at least part of the casing. A strap having an opening defined in the strap for receiving a handle assembly is provided to attach a carrier to a wheeled carrier in order for the carrier to be supported by the wheeled carrier. In one implementation, a trench isolation method comprises forming a series of isolation trenches into a semiconductive substrate.
