The present invention provides for a process for preparing 6,6-Dimethyl-3-aza-bicyclo3. The electrodes are mounted in pairs on microfabricated supports, which are formed from conducting parts on an insulating substrate. A reflective coupler with a coupler body, and an interior volume passing therethrough is positioned proximal to the optical pumping source. In some instances, rotation may be automatically performed upon drawing of a division line, deletion of a sub-image, receiving a specified user command or type of user input and the like. The inlet port of the inflatable curtain can receive a gas guide that extends from an inflator.
