Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for identifying main content of a webpage. In one aspect, a method includes receiving a web document and analyzing the web document to identify sections of the web document and to determine a sequence of the sections. Each section corresponds to a logical portion of a graphical representation of the web document. A particular section is identified as containing main content of the web document based on characteristics of the particular section relative to characteristics of the sections overall. A modified web document is generated based on the identification of the particular section containing the main content.

Abstract: A flexible process controller for coordinating the operations of various equipment is disclosed. Briefly stated, in the preferred embodiment of the present invention, various parameters of the sub-systems in a HVAC system are monitored and made alterable or changeable. These parameters are transmitted to and controlled by a flexible process controller which thereafter cooperates with a motor drive controller. Logic incident to and resident in the flexible process controller consider the various parameters monitored and allow the user or the system to minimize power consumption amongst one or more of the sub-systems while maximizing efficiency and operability.
