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.

Electronic Serial Number Identification Technique
This circuitry allows an electronically readable serial number to be
implemented on complex electronic circuitry incorporating Level Sensitive Scan
Design (LSSD) criteria.
The binary coded decimal serial number is generated by the
deletion or non-deletion of programmable links 14. The links 14 are
each connected in series with a resistor 16 between sources
representing the logical zero and one levels. Interrogation for the
serial number is accomplished by pulsing the read gate to read the
serial number into the shift register stages 10 through AND gates 12.
The serial number is scanned out of the shift registers by pulsing
the A and B scan clocks for the LSSD system.
