The principles of the present invention provide the ability to flexibly change the delivery point and time for a mail item, while the item is en route. In one embodiment, a semiconductor device includes a plurality of first features disposed in a first material layer. The equipment according to the invention thus comprises a settler, which is essentially trapezoid in shape so that its cross-section is wider at the feed end of the settler and gets smaller towards the rear end of the settler, from whence the separated solutions are discharged from the settler, and the settler is equipped with at least one device to dam up the dispersion. The wide-range of input allowed by the up-converting device enables the continuance of power drain from the UltraCapacitors, i. A fifth wheel trailer hitch member has a base portion.
