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.

Connectors, such as the one shown in the IBM Technical Disclosure Bulletin
18, 2460 (January 1976), provide a means for making connections between a
printed-circuit card and a printed-circuit board.
Shown above is a card structure which facilitates increased density. It has a
plurality of internal voltage planes V1 to V4 and a plurality of signal planes
designated S1 to S4. The signal planes S1 and S4 do not extend all the way to
the end of the circuit card. A first row of contact tabs T2, located in the thicker
area of the card, are connected to the signal planes or voltage planes through
conventional plated through-holes H2.
A second row of tabs T1 is located on the thinner portion of the circuit card.
Some of these tabs are directly connected to the internal power planes through
plated through-holes H1, and others are connected to the circuitry through
printed-circuit lines L1.
Contact blades C1 make contact with each of the tabs T1 and T2.
