Shortly after network initialization, the software architecture is superimposed on the flat hardware architecture, re-arranging communication links to provide an efficient hierarchy of control and substituting working agents for compromised agents as necessary in the network. All of this is done in a “live” network, not requiring shutdown, or even reduced operation to accomplish. This “dual” architecture (hierarchical software and flat hardware) provides excellent reliability in those “layered” network applications requiring near total reliability, such as security surveillance.]]></description>

<description><![CDATA[A method and apparatus for validating the flow calibration factor of a Coriolis flowmeter. In accordance with a first embodiment, an improved material density is obtained by measuring material density when the temperature of the material is equal to a predetermined reference temperature. In accordance with a second embodiment, a preprogrammed data base stores density/temperature relationships. Improved density information is obtained by measuring the density and temperature of the material, applying the measured density/temperature information from the data base, and obtaining density information compensated for a predetermined reference temperature. The improved density information obtained for both embodiments is unaffected by temperature changes and is used to validate the flow calibration factor. The flow calibration factor compensation for pressure changes and changes in material composition is obtained in a similar manner.]]></description>
