Abstract: A multi-functional cosmetic pad (100) for either absorbing low tension substances from the skin or applying and smoothing new-makeup, comprising a porous low energy surface (110) and crease resisting features for preventing the formation of creases, folds, or kinks when the surface is rubbed over the skin. A cosmetic pad (100) in accordance with a preferred embodiment of the invention comprises a soft, conformable, and porous polytetrafluoroethylene membrane layered over a flexible backing (204). Flaps (308) cutout from a top portion (201) of the backing (204) form a retractable handle for easily gripping and manipulating the cosmetic pad (100).

Abstract: A compact and energy efficient photosynthetic filter for purifying and conditioning aquarium water comprising a receptacle (108) for holding aquarium water, a growth element (202) having a growth surface (204) of sufficient texture for growing adherent photosynthetic organisms, and a non-continuous illumination device for providing photosynthetic-sufficient illumination to the photosynthetic organisms. A non-continuous illumination device in accordance with a preferred embodiment of the invention comprising a continuous light source mounted over a submerged, rotatably mounted, elongated, and substantially cylindrical growth element (202). Rotation of growth element (202) under the light source providing non-continuous illumination to adhered photosynthetic organisms. Rotation of the growth element is preferably powered by a motor (212) or turbine (600).
