Patent No. 3592965 Apparatus for converting cathode ray portrayable information to spatial images (Diaz, Jul 13, 1971)
Abstract
This invention relates to apparatus for converting an optical image or electrical signals obtained from scanning an image, or from other information, into an electromechanical or sensory image conforming thereto. The invention, while applicable to many fields such as printing, metal forming, image reproduction in general, and others, nevertheless will be explained in connection with a preferred embodiment thereof which enables a blind person to perceive what is ahead of him by virtue of a sensory image or outline on his skin, preferably the back or other large area.
Notes:
In other words, the basic apparatus
of the invention which comprises a source of information displayable upon a
cathode-ray tube or equivalent; coincident type scanning means responsive to
the information scanned may have multiple end uses as have have herein been
before named. Another such use is as a multiple electrical switch which could
readily have 10,000 or 2,000,000 contacts all individually actuable. Therefore,
it is intended that the invention be only limited by the scope of the appended
claims wherein what is claimed is:
