A memory module assembly includes a heat-sink plate attached to one or more of the integrated circuits of a memory module PCBA by adhesive. The virtual file system includes the portable media drive and allocated storage of a storage server. Further, since the offset circuit and the logic circuit are formed using the transistors of the same conductivity type, a display device can be manufactured at a low cost. The strut length adjustment assembly retains a strut and includes a strap retention mechanism that is configured to releasably engage the strap. The system can alternatively use a supply of cool liquid pumped by a pump through a conduit adjacent to a liquid fuel component to cool the component. The HID lamp is started at full line voltage, and after a sufficient operating interval ensuring that the lamp has achieved a sustaining temperature, the operating voltage applied to the lamp is reduced, effecting considerable savings in energy use, with little or only an acceptably small decrease in light output from the lamp.
