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.
A flexible, cylindrically-shaped device acts as a heatsink when attached to a
heat generating module mounted on a printed circuit card and interfaced with an
enclosure that also acts as a heatsink.
A metallic shell 1 (Fig. 1), having high thermal conductivity, is mounted on a
module 2 by a clamp 3 or by other suit means (brazing, soldering, adhesive).
The module 2 is mounted on a printed circuit card 4. A card enclosure 6 is
placed over the entire PC card 4. When placed in the closed position, as seen in
the end view in Fig. 2, the shell serves as a finned surface and conduction path,
and the cover serves as a heatsink.
As seen in Fig. 2, the shell 1 compresses when the enclosure 6 is closed,
increasing the contact area between the shell 1 and the module 2, and the shell 1
and the enclosure 6 to enhance heat transmission. The shell material is thin, so
that it does not increase the air flow resistance of the assembly. Airflow, in the
direction indicated by arrows (Fig. 1), removes heat from the entire configuration.
