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.

Computer keyboard with user feedback system
This invention is an special type of computer keyboard and optional driver software with semi-translucent keys and a LED under each key. The purpose of the LED is not for illumination in dark environments, but that feature can be enabled. The device driver for the keyboard is capable of illuminating the LED under each key individually. This is helpful for a number of applications. For example, applications can visually show on the actual user's keyboard what button combinations are expected to be pressed for certain functions. Take for example, when a person navigates through the menu in a word processing program to enable bold text, the driver could illuminate the "CTRL" and "B" keys for a short time to teach the user that particular shortcut. This information is easily obtained from the current operating systems. This is also useful for kiosk type applications where a user does not and should not need to understand a system or software after initial use. Children can also benefit from this type of keyboard when learning to use computers. Coupled with special educational software, a greater benefit is realized. This keyboard would not be expensive to manufacture , with an estimated cost delta of less than $10 over existing USB keyboard implementations.
