Gate electrodes are formed on a semiconducting carbon nanotube, followed by deposition and patterning of a hole-inducing material layer and an electron inducing material layer on the carbon nanotube according to the pattern of a one dimensional circuit layout. The medium includes a nanoweb layer and a scrim, wherein the nanoweb layer contains fibers with a number average diameter less than 1 micron and layer thickness less than 50 microns. Alternatively, measured activity levels can be transmitted over a system bus to a centralized power management controller which, responsive to the activity level packets transmitted by remote memory modules, direct devices of those remote memory modules to a reduced power state. The collar has a length to penetrate through the bolt hole in the upper wall of the upper casing.
