A method and device that support automatic scaling of display output of a shared application are described. The first metering device and the second metering device are constructed differently from one another with respect to metering principles thereof. The housing further includes an exit port for co-extruding the materials on the substrate to generate a relatively fine feature with a relatively high aspect ratio. Each router port extension functional unit comprises a virtual channel agent and a LAN agent. Corner and T-walls are made by simple cuts in the standard blocks.
