Abstract: A method and apparatus or arrangement, for monitoring the operating characteristics of valves, principally to monitor for failure of a valve. The method including measuring a pressure differential across a valve 1 and comparing the measured differential with a required differential. If the measured differential is acceptable relative to the required differential, the valve is deemed to be operating acceptably. If the differential is not acceptable relative to the required differential, then further monitoring in the form of flow sensing takes place and is compared relative to required flow characteristics. The method employs a comparison of the pressure differential and the sensed flow characteristics to determine whether the valve is operating acceptably.

Abstract: A system and method generates a map representation of information from a BI (business intelligence) application. The BI information is used to generate map data, which in turn is used to generate a map representation. The system and method are arranged to generate the same thematics in a representation as provided by BI application. For example, if the BI information is information on crime in a particular area, the map representation will present the same theme in a spatial frame of reference, using similar metadata (thematic data) to express the theme on the map representation.
