The present invention provides a light-transmitting metal electrode including a substrate and a metal electrode layer having plural openings. The slitting mechanism has a rotatable carousel of rotatable slitting shafts which extend across the width of a media web arranged to pass the slitting shafts along a path. The interface includes displayed menus of selectable, hierarchically organized options and sub-options which guide the user through the relevant processes. The memristor, returns to an electrically open circuit condition after the short circuit is removed.
