A system and method allow for a platform to be collapsed and moved in a vehicle. The converter converts two pairs of differential current signals into two pairs of differential voltage signals. When the pair of Halbach arrays move along the track and the track is not located at the first plane, a current is induced in the windings and a restoring force is exerted on the pair of Halbach arrays. Based on the historical profiles, a second subset of entities having transaction behavior associated with a transaction is selected, the transaction behavior being predictive of at least one targeted outcome from the set of possible outcomes. These two codes provide for protection both for an error anywhere in the maximum length of the packet as well as for an error replicated two or three times by the descrambling process. The system may determine a measure of an equivalent number of trees saved, or the number of carbon credits gained, by not producing hardcopies of transmitted pages.
