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.
It has generally been the rule that arbitration on a common bus is normally resolved by allowing only one device at a time to use the bus. This inherently limits the system performance and speed.

Multiple Master Simultaneous Use Of A Common Bus By Space Separation
It has generally been the rule that arbitration on a common bus is normally
resolved by allowing only one device at a time to use the bus. This inherently
limits the system performance and speed.
A technique is disclosed for changing the configuration of a bus structure to
allow the simultaneous use of the bus by more than one master and related
devices. This is accomplished through a combination of time separation and
space separation depending upon the particular modes of operation.
The time separation bus structure is illustrated in Fig. 1. This shows a master
device and a plurality of related devices on one side of the arbitrator, and a
second master and a second plurality of related devices on the other side of the
arbitrator. The space separation is shown in Fig. 2. Here again, a first master
device and a first plurality of related devices are shown on one side of the
arbitrator, and the second master device and second plurality of devices are
shown on the other side of the arbitrator. As indicated in the figure, the
connection through the arbitrator is broken so that the bus interconnecting the
first master and the first plurality of devices is isolated from the bus sector
interconnecting the second master and second plurality of related devices.
As shown in Fig. 1, the arbitrator is located between the two masters and has
the capability of physically disconnecting the bus between the two...
