Patent
Electrical cells and batteries and methods and apparatus for making the same
TL;DR: A laminar battery comprising subassemblies made by laminating cellophane to a sheet of conductive plastic on which a series of metallic electrodes have been formed is described in this paper.
Patent
Diffusion transfer process using processing composition impregnated image-receiving element
TL;DR: In this paper, negative-positive reflection prints are obtained by a diffusion transfer process wherein the image-receiving element is impregnated with a processing liquid and consists of a transparent support, an image receiving layer, a light-reflecting layer and an opaque layer.
Patent
Method and system for image reproduction based on significant visual boundaries of original subject
Edwin H Land,John J. McCann +1 more
TL;DR: In this paper, a subject is scanned to detect brightness ratios across visually significant boundary lines or edges between different areas of the subject A signal is developed which represents the sequential multiplication of edge ratios of brightness detected on opposite sides of boundaries.
Patent
Optical system employing polarized light
TL;DR: In this article, a new and improved optical system employing polarized light was proposed, which has for its object the provision of means to so polarize light emanating from a source that a considerable percentage, for example substantially more than fifty percent, of the light traversing the means of the system can be avoided.
