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 design that provides inexpensive communication around a populated PCI card. The design accommodates thermal concerns, is easy to install, and has unique light transmission properties built into the lightpipe.

Lightpipes Essentially "Through" a PCI Card (Single-Wide or Double-Wide)
Disclosed is a device that provides an inexpensive (lightpipe) means of communication
around a PCI card populated with components. Existing solutions utilize an LED
diagnostics card with a cable and planar board connector resulting in an expensive
solution. Other known solutions utilize space between PCI slots whereas the disclosed
solution is within the PCI allowed space. Known solutions are also expensive and do
not provide a lightpipe path area around components such as heat sinks in a
double-wide PCI application. This new design can be installed on any industry standard
This design accommodates the ability to fully populate the entire card with
components, not just the front or back half of the card. These components may include
taller items such as heat sinks and capacitors, which can take up both PCI slots on a
double-wide card. By having the base completely open, the thermal impact to the card
is minimal. Additional features such as louvers, etc. can be added to the body of the
design to maximize the cooling of the card, processor, and heat sinks. The lightpipes
used on this assembly have four bends designed to route around the taller components
on the card. The lightpipes are convex and textured on one end to allow brighter light
transmission. The end of the lightpipes that are on the card are widened and polished
to maximize the amount of light captured from the LED. The e...
