The switching sequence of a phase-shifted zero-voltage-transition full bridge converter circuit is alternated between two modes by periodically reversing the switching sequence for diagonally opposed switching devices of the bridge. In another aspect, the invention inhibits particular elements in particular installments to produce a fixed color bias between colorants of at least one colorant pair; the other colorant is statistically downweighted to correct the bias. The first electrodes are provided on the first major surface to extend in a first direction. Also, the core layer may also may be made up of liberated branching metal nanostrands or a plurality of electrically-coupled, electrically-conductive particles, each taking the from of an electrically-nonconductive, nonmetallic substrate with a metal coating. The computer optionally communicates with other computers andor devices through a network. In one embodiment, a system can provide a combined product for dispensing from a product dispenser.
