The mark consists of The capitol "Letter R, thena space, then the capitol "Letter D. Attached to the left vertical straight line, on the outside of the "Letter D," are two very short, horizontal lines. The short horizontal lines are attached (from top to bottom) at the 1/3 point and the 2/3 point. This creates the impression of the "Letter D" being an electrical plug. Simultaneously, it creates the impression of a capitol "Letter E" (as negative space) between the "Letter R" and "Letter D.".
