A spatially modulated light beam is projected, reflected, and redirected through a prismatic optical panel to form a video image for direct viewing thereon. The method further includes forming a second metal layer, performing a third PEP to form a source and a drain on the substrate and to simultaneously remove a portion of the doped n+ layer to expose the amorphous silicon layer, and finally, forming a passivation layer on the substrate. The non-overlapping down scrambling code is set to a newly established base station apparatus based on the acquired contents. Additional improvements include a larger opening to more quickly fill and inspect the powder within the chamber. The gateway has a memory to store a copy of user data associated with each endpoint.
