A method, apparatus, and article of manufacture for a data warehouse programs architecture. A lower silicon oxide film, an upper silicon oxide film, and a silicon nitride film to be interposed there between are formed on a spin-on-glass film. A power diode formed in the second region has a first load terminal on the first surface and a second load terminal on the second surface. The foregoing transmit power adjustment procedure ensures that the forward receiver receives forward data only from the forward transmitter, and prevents other proximate wireless devices from inadvertently intercepting forward data transmitted by the forward receiver.
