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.

Contact Extraction Tool
Contact pins are extracted from retainer holes, without damaging their
retainer leaves, so that the pins may subsequently be reused.
Contact pins, held in connector block retainer holes by flexible retainer
leaves, are frequently removed by wedging a stiff wire (such as an unbent paper
clip) into the retainer hole. While this technique does release a pin's leaf from its
wedged position against the connector wall, it usually damages the leaf,
preventing reuse of that pin. Also, the stiff wire must be inserted into the retainer
hole only on the leaf-side of the pin.
The extra tool has a flat formed at the end of a stainless steel rod mounted in
a pin vise. The tool is inserted into the retainer hole, in any convenient
orientation, and then rotated to bring the flat against the leaf. The leaf is thus
gently retracted, and the pin may be withdrawn and reused.
