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.

Standard LSI Module
This article describes a technique by which off the shelf standard LSI (large-
scale integration) modules may be used to model Level Sensitive Scan Design
When a new machine is being developed, it is very desirable to
provide one or more early hardware logic models for a variety of
1. prove system feasibility,
2. establish system function,
3. determine system compatibility with other systems,
4. study human factors, and
5. provide a vehicle to debug system operation.
In LSSD methodology Vendor Transistor Logic (VTL) modeling becomes
cumbersome and bulky since VTL models must maintain block to block
correspondence and functional integrity with the LSI logic that is being designed.
To solve this problem a set of off the shelf modules including shift register latches
(SRLs) may be used.
The LSSD methodology utilizes sets of memory elements (SRLs) and
combinatorial logic. The memory elements can be provided by the standard
(SRL) modules in accordance with the drawing and the combinatorial logic via
programmable logic arrays (PLAs) or standard off the shelf VTL modules.
