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.

Concentrator Solar Cell with Tracking Control Information
Automatic tracking in solar photovoltaic devices can be performed by
building into the concentrator detecting capability that will drive a servo when the
focused beam departs from the center.
The position detector can be made as part of the photovoltaic area, with the
area divided into quadrants that give no net signal when the beam is centered, as
shown in the figure. The voltage signal is input into a high impedance system in
order to reduce the load.
