The present invention relates to a means, system and method for controlling the storage space required by a storage means which contains information items associated with an information transfer application. A circuit architecture is described that is configured to charge a capacitor to an initial amount of charge, modulate the amount of charge stored in the capacitor based on a control signal, and generate a stimulation current pulse that has an amplitude based on the amount charge stored in the capacitor. The first end of the elongated cylinder is configured to receive a drive hub. Pairs of adjustable diagonal struts reach from a forward face of the trailer to each of the curved panels to hold the panels in position.
