Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Copier with Scanning Fiber Optics
A xerographic copier with an arcuately scanning fiber-optic bundle images a
photoconductive drum from documents on a curved platen.
Curved platen 10 is adapted to receive original documents under flexible
cover 11. Fiber-optic bundle 15, with illuminating lamps 16 and 17 assembled as
a unit, is arcuately scannable through a segment of an arc between the position
shown and the final scan position 20. This fiber-optic assembly 15 rotates on an
arc about the center line of drum 22 which has a photoconductive surface. The
scanning of the documents on platen 10 is thus imaged onto the photoconductive
surface of 22 and thereafter processed by conventional means, including
developer 24, copy paper handling mechanism 25, corona 26, and the like. The
speed of drum 22 is synchronized with the scan speed at the document position,
allowing full-size imaging of the original document onto the photoconductive
surface. The device, as shown, is adaptable for book copying as well as flat
original documents, and is well suited for automatic document feeding past the
optic bundle 15 in a locked or parked position as well as for scanning, as shown
