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.

Simulating Color Deficiencies
It has long been known that a significant percentage of observers have color vision that is markedly different from the average observers. They are different in different ways and degrees, and can be characterized by medical categories. For example, protanopia is severely reduced discrimination of the reddish and greenish contents of colors with reddish colors appearing dimmer than normal. Tritanopia is severely reduced discrimination of the bluish and yellowish contents of colors. And rod monochromatism is no color discrimination, and brightness typical of scotopic vision.
The current market of color devices are all designed for people with normal color vision. Because there are certain shades of colors that color defectives can not see, it creates some problems. (1) Color defectives will not be able to see details on some images and the designers of such images (e.g. advertising or web pages) may be unaware of it. (2) Printing the full gamut for color deficient people may waste toners/inks. Therefore, it is of value to design color devices to simulate what color deficient people see.
Our invention idea is to design a system to calibrate color devices for color deficient people. We could build a database for the different kinds of color deficiencies, and then build color management systems based upon them. When a color defective person enters his/her information, the device will be calibrated accordingly. This idea can be widely app...
