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.

Brailler Computer Interface
This interface enables a Perkins brailler to be interfaced with an IBM
Personal Computer to be used as keyboard input device.
A brailler computer interface device includes an IBM PC interface card, an
interface cable assembly and a software program that interfaces with a voice
synthesizer to indicate computer response. The input device consists of a
vacuum-formed ABS cover with ten mounted micro switches that are activated by
different mechanical functions of the brailler. An activated switch indicates a
ground condition through cable assembly to an IBM PC card mounted in the
computer. The cover mounts on the bottom of the Perkins brailler or electric
brailler by removing existing base and mounting with screws. Connector for
interface cable assembly is built into the cover. See the figure.
