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.

Icons for Local Area Network Connections
The figures illustrate three symbols that provide a method of identifying the
IEEE 802.X local area network (LAN) connections as described at the medium
access control (MAC) and physical layer.
The symbols are incorporated into a product so that labeling
differences are minimized in units distributed world wide. The three

Each of the symbols is designed to give an indication of the type of LAN at
the physical connection. A schematic symbol for a ring connects the blocks for
the Token Ring (Fig. 1). A schematic symbol for a bus connects the blocks for
the Token Bus (Fig. 2). A schematic symbol for a line connects the blocks for the
Ethernet (Fig. 3).
The blocks are arranged in the same pattern in each of the three symbols to
indicate inclusion in a single protocol family (IEEE 802.X). The arrangement is
also non-hierarchical to indicate that none is a controller of the LAN symbolized.
