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.

Fabrics To Aid Computer Graphic Input
A printed fabric placed upon a human form or other smoothly contoured
surface provides reference points for digitizing an object that otherwise would not
readily provide good graphic input.
It is usually difficult to describe mathematically the shape of the human body
or the draped shape of clothing worn by persons. Digitizing tablets or optical
scanners can be used to encode complicated three dimensional shapes if the
surface thereof has sufficient distinctive markings or other features that can be
precisely identified. If a person or other object is fitted with a fabric that has a
bold pattern imprinted thereon, such a pattern can provide the desired markings
for enabling the surface of the object to be precisely encoded.
Any printed fabric may be used to provide surface markings. The variety of
patterns that can be utilized is illustrated by the examples shown in Figs. 1 to 4.
Fig. 1 shows a simple grid pattern, which in some instances may not provide
sufficient discrimination between points. Varied spacing of the grid lines, as
shown in Fig. 2, can improve the discrimination and aid automatic scanning.
The use of different colors or grey shades, as indicated in Fig. 3, still further
improves the discrimination. The ultimate degree of discrimination can be
achieved by printing grid coordinates or other distinctive indicia adjacent the
reference points, as shown in Fig. 4, which is particularly well suited for manual
