Abstract: A system and method for viewing of two-dimensional (2D) color-encoded images that simulate depth with color include a pair of goggles, the goggles having two lenses that each include a high chromatic dispersive prism disposed adjacent a low chromatic dispersive prism, and a 2D color-encoded image being viewable with the lenses of the goggles which separate colors of the image into different convergence points in the visual field of a user, thereby producing a chromostereoscopic effect.

Abstract: A spa cover lifter for moving a spa cover from a closed position to a storage position includes a drive mechanism, a fixed base and a lifting arm assembly. The lifting arm assembly is mounted to first or second leaves of the spa cover. The lifting arm assembly is driven by the drive mechanism and is moveably mounted to the fixed base. The lifting arm assembly includes a cover pivoting assembly and a cover transporting assembly. The cover pivoting assembly is driven by the drive mechanism to move the cover from the closed position to an intermediate position and the cover transporting assembly is driven by the drive mechanism to the move the cover from the intermediate position to the storage position. The spa cover lifter has an automatic shutoff for cutting power when an obstacle is encountered. A method of moving the spa cover is also disclosed.

Abstract: Pool covers embodying the invention are formed of a very dense mesh material which ensures substantially one hundred percent shade while allowing water to pass uniformly through the cover and which is adequately strong to support the weight of an adult. The pool cover is formed of plastic fibers which are interwoven to form a dense mesh which is then subjected to a pressure and heat cycle to ensure that the resultant material has the requisite properties for allowing water to pass through at a desired rate (e.g., 0.1 to 5 gallons per square foot per minute) while blocking light (e.g., 100% shade). Thus, a self-filtering safety pool cover is formed which allows for water to pass through uniformly across its surface while blocking sunlight.
