Abstract: Disclosed are methods, processes, systems, and compositions of matter that enable the transfer of targeted constituents from a dilute state to a final concentrated state. Exemplary dilute constituents are carbon dioxide or humidity as found in air or other gases; and exemplary final states, respectively, are purified carbon dioxide or condensed water. Such transfer from dilute sources is understood generally to require more energy consumption as the source phase becomes more dilute in the targeted constituent. The present invention shows how a different governing principle, i.e. reactive disguisement, is applied to create a concentrated final state without relying on heat flow or pressure swings to actively concentrate a targeted constituent. The primary field of invention is chemical separation.

Abstract: A knee protection system has a garment such as pants with a closed pocket. A shaped elastomeric pad is encased in the closed pocket. The shaped pad has a number of sub-pads including a patella pad, a pair of side pads and a top pad. The side pads protect the used when they roll on their knees and the top pad protects the user knee when they lean forward. The elastomer does not absorb water, can be washed and protects against both sharp points and more general pressure.
