Abstract: A simple and inexpensive portable laptop computer hood is disclosed in the form of a sheet with panels, flaps, fold lines, and a single viewing aperture. The single sheet of foldable material can be folded into a 3-dimensional hood operational configuration or a flattened configuration for easy storage and transportation. Because these sheet's panels do not lock into specific positions when the sheet is configured into a 3-dimensional hood, they can be easily repositioned to accommodate variations in both laptops size dimensions and individual operator preferences. A notable aspect of the 3-dimensional configuration of the laptop computer hood is that it allows the laptop computer's keyboard to remain outside of the light-protected compartment area for easy access by the laptop computer's operator. Strategically placed side panels enable the unit to independently stand on its own as the laptop computer is inserted into the compartment.

Abstract: A portable viewing tunnel for transparencies, medical radiographs, mammograms and other trans-illuminated materials is presented. Its proper use provokes human physiologic darkness adaptation primarily by means of an elastic neoprene rubber laminate cylinder with a malleable distal aperture which can be manually shaped to fit the form of the dark or detailed areas of interest being viewed. This characteristic prevents light which is emanating from bright sources within or next to the trans-illuminated image from reaching the eyes and spoiling physiologic darkness adaptation. Additional steps to exclude stray light include a soft, form fitting goggle on the proximal end to contact the face around the eyes forming a light tight junction between viewing tunnel and the eyes. An intermediate lens board is included for easy changes in binocular magnifier lenses. This device replaces most of the need for bright lighting or masking for viewing dark areas on transparencies and other trans-illuminated materials.
