Gas Circuit Breakers(GCB) - Hitachi

With high voltage and high current distribution systems, a Gas Circuit Breaker (GCB) that uses Sulfr hexafluoride gas, with three times the insulating ability of air, is applied. This technology releases a circuit of electrodes within compressed gas, extinguishes the generated arc by blowing a stream of supersonic air, and interrupts the current.

Mobile Displays: Technology and Applications - PDF Free Download

An ultra high resolution display (e.g. WUXGA at 1920 1200) only offers slightly more than 2 mega pixels. Thus, for a desktop monitor, there is a long way to go before reaching the eye resolution limit. The single factor that makes this difference is the large display size disparity between a mobile display and a desktop monitor.
