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.
Disclosed is a method that creates a thermal tunnel to direct fan airflow, and separate fresh air and exhaust air. Benefits include preventing heated air from being re-circulated within the system.

Apparatus for a Thermal Tunnel Using
Internal and External Fans
Disclosed is a method that creates a thermal tunnel to
direct fan airflow, and separate fresh air and exhaust air. Benefits include
preventing heated air from being re-circulated within the system.
Currently, the thermal management of CPUs and other
heat-generating components is difficult. External fans blow air
indiscriminately into the case, reducing cooling efficiency and requiring the
use of larger, more expensive fans. In addition, fans are usually mounted
directly to the heat sink within the system case, causing heated air to be
re-circulated with the cooling air.
The disclosed method creates a thermal tunnel (i.e.
ductwork) that directs and concentrates airflow, separating fresh air from
exhaust air and preventing heated air from being re-circulated within the
system. The disclosed method also reduces junction temperatures. The ductwork
can be lengthened to include multiple components or areas of the board. The
ductwork can also be designed to accommodate an internal or external fan, or to
work with both types of fans simultaneously. (see Figures 1 and 2).
The disclosed method separates fresh air from exhaust air,
and prevents heated air from being re-circulated within the system.
