Abstract: Methods for reconciling an address database include comparing addresses in an update database to addresses in a production database. A second comparison of unique addresses from the first comparison is executed, the second comparison allowing matching of addresses that the first comparison did not match.

Abstract: Inflatable hull configuration and connection for a multihull vessel. The inflatable hulls have a longitudinal structural member fastened to the top of the inflatable hulls, with a central body of the multihull vessel supported on the longitudinal structural members by forward and stern legs. The forward legs support the forward part of the central body through a ball joint that allows the forward legs to rotate as a unit relative to the central body, and have their lower ends attached to the forward part of the longitudinal members, each through a spring supported ball joint. The stern legs are each rigidly coupled to the central body, with their lower ends connected to the aft part of the longitudinal members to allow rotation about a vertical axis and a transverse axis, but not the longitudinal axis. A detailed embodiment is disclosed.

Abstract: Variable planing inflatable hull system having a planing surface on inflatable hulls at the side and disposable central hull. The central hull is typically a rigid hull, with the inflatable hulls providing low wetted area planing surfaces for speed, shock absorbing and efficiency of the vessels. Various embodiments are disclosed.

Abstract: A method for coding a plurality of postal addresses. The method includes associating an identifier with a postal address having a first plurality of elements, and associating the identifier with a second plurality of elements if the second plurality of elements is associated with the postal address.
