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.

Magnetically Coupled Three Junction Injection Device
Magnetically coupling the inputs to a three-junction injection device can
increase the margins.
The figure is an electrical diagram of a 1-3-1 injection device with the inputs
magnetically coupled to the device.
The value of the mutual inductance L(m) is such that when just one current,
I(A) or I(B), is present, there is very little phase drop across the inductor L. This
condition gives L(m)=L/(m + 2), where M is the number of center junctions.
