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.

High Current Carrying Modular Laminar Bus
The bus arrangement shown allows the possibility to distribute large currents
and the ability to tailor the distribution tolerances on a printed circuit board.
In order to distribute larger current, in excess of 600 amperes, to tight voltage
tolerances, the ability to tailor the system, that is, distribute the current to the
loads at more frequent intervals, was necessary. The present bus concept
allows the use of multiples of assemblies and the use of the number of
assemblies required to equalize the voltage tolerances.
Laminar buses 1 are provided which have tabs 2 soldered to pads on the
board and the buses extend between rows of modules to carry current to the
modules. One end of each laminar bus is fastened to a terminal block 3 which
electrically connects the bus to a mainan common power input bus 4. No fixed
grid is required; however, it may be desirable. Instead of using a main common
bus bar, the inputs to the laminar buses can be commoned together, if required,
with flat or round wire, or rigid bus bars.
