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.

Magnetic Data Entering Device
A device is described for entering large amounts of serialized data from a
storage device through a magnetic stripe badge reader station.
As shown, the device consists of a single-turn coil 1 of a nonferrous
conductor that is bonded to a nonmetallic card 2 of the same size as an IBM
magnetic badge. For entry, the coil is statically positioned so as to be centered
under a read head 3 in the reader station.
To transmit data, coil 1 is driven to produce complete 180 degree reversal of
the magnetic field. This in turn causes read head 3 in the reader station to see
flux transitions similar to those produced by moving a magnetic stripe on a badge
past the head.
The flux changes or transitions are programmed in a format that is
recognizable by the reader and its supporting devices.
