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.

A keyboard is described in which the required circuit control board is almost
horizontal, thus providing a relatively low profile.
In most present-day keyboards, an additional bottom cover is needed to
enclose the circuit card. In the present construction, a base frame combines the
dual functions of circuit card mounting and bottom cover.
In the drawing a cross-section of a keyboard is shown having a base frame
with a portion supporting the keys. One end of this portion has attached an L-
shaped extension on which the circuit board and associated connector are
mounted. The base frame may be an extrusion or rolled section with a riveted or
welded extension. The base frame fits within a cover having an aperture
through which the keys protrude.
