Abstract: The Reconfigurable Wheel-Track (RWT) is a novel mechanism that allows a wheel to transform into a track, and vice-versa. The wheel permits a vehicle to travel quickly over smooth and semi-rough terrain, then, on-the-fly, transform rapidly into a powered track for crossing extreme terrain. The reconfigurable wheel-track consists of several main components: an outer tire/tread, drive mechanisms for the wheel and track, support mechanisms for the outer tread when in either wheel mode or track mode, and a reconfiguration mechanism that facilitates the transformation from a wheel to a track and vice-versa. The reconfigurable wheel-track includes sensing, actuation, and controls to facilitate efficient and effective transition from wheel to track and vice-versa, and securely maintain each shape.

Abstract: Described is a moisture-vapor-permeable and oxygen-permeable adhesive dressing for use in supplying a topical medicament to human skin in a controlled release manner, which dressing is unaffected by and impermeable to water in the liquid phase, which dressing when in use on human skin consists essentially of:(i) a polymeric backing material lamina having two surfaces, a first substantially planar surface and a second substantially planar surface;(ii) adhering to said first planar surface of said backing material a medication reservoir lamina having two surfaces, a first substantially planar surface and a second substantially planar surface, consisting essentially of an intimate mixture of:(a) a polyvinyl chloride polymer;(b) a polymeric plasticizer intimately admixed with said polyvinyl chloride and compatible with said polyvinyl chloride; and(c) a topical medicament compatible with said polyvinyl chloride and said plasticizer;said first substantially planar surface of said medication reservoir lamina adherin
