A method of fabricating an article usable in an imprint lithographic process is disclosed. In one embodiment, the optical switch device includes a substrate. The client computer applies a set of correction procedures to the decrypted results set to remove the inaccuracies therein. The gaming machine also includes a light piping material positioned in front of the curved transparent material for illumination of the display. Two electrodes are disposed on two opposite surfaces of a proton exchange membrane, to obtain the membrane electrode assembly. Here, in a wireless system using the centralized MAC protocol where a time synchronization and a band allocation may be performed by a single central control unit, when a signal blockage occurs while a data communication is being performed via a direct path between a source device and a destination device, the detour path may be quickly provided.
