The \u201cPull and Swipe Navigation\u201d comprises a set of heuristic gesture-based commands overlaid on a smart user interface that optimizes for dynamic content and ease of navigation on touch screen devices. A relatively rigid platform is positioned within the raft and configured to provide a stable surface for the person during use of the device. The method includes synchronizing each upstream and downstream link. After an voltage is applied, an oblique electric field is produced by these bias instruments. Summary data which summarizes each rollover table according to predetermined criteria is stored in a summary table with the reference to the corresponding rollover table. The package is constructed of a flexible material capable of retaining a plurality of wipes.
