  • Patent number: 7991741
    Abstract: A system and associated method for synchronizing a record with a web document. A synchronizer selects a web document that is stored in a published web document repository of a content management system. The oldest web document since the latest update is selected and checked for availability. The synchronizer locates a record that corresponds to the selected web document. The synchronizer then checks respective version of the web document and the record to determine whether the record correctly represents the web document. The synchronizer then verifies whether the selected web document is available to users to avoid synchronizing latent web document that is not available to users. The synchronizer updates the located record.

  • Patent number: 6791587
    Abstract: A navigation manager component cooperable with a user interface renderer is described. The navigation manager manages one or more navigation units and maintains a navigation unit cursor. Each navigation unit is associated with another navigation unit managed by the same navigation manager. The navigation manager provides a range of navigation services, which operate upon the navigation unit cursor. These services include a service to navigate forwards and a service to navigate backwards. These services take into account the associations between navigation units in order to determine the correct sequence of navigation units for forwards and backwards navigation. The services also determine whether the items represented by each navigation unit include eligible items or items for which data entry is incomplete. In this way, navigation units for which all the items represented by the navigation unit are ineligible can be passed over by the navigation services, to that they never become current.

  • Patent number: 6476828
    Abstract: Systems, methods and computer program products are provided for building and displaying dynamic graphical user interfaces (GUIs) that can be updated automatically without requiring code-level modification and recompiling. In response to a request to display a particular GUI on a computer display, an Extensible Markup Language (XML) data group is selected from a plurality of XML data groups and an XML display layout is selected from a plurality of XML display layouts. The selected XML data group includes one or more aggregations of data hierarchically ordered within the selected XML data group. XML data items are hierarchically ordered within each of the aggregations of data. The selected XML display layout contains one or more areas that define respective GUI display spaces within which XML data items from the respective aggregations of data can be displayed.

  • Patent number: 6236087
    Abstract: An input protection device is provided for protecting a circuit structure which is coupled to a first node, the device comprising a first lightly-doped region of P-type material with a lightly doped well of N-type material formed in it. Two regions of heavily doped N-type and P-type material, which are electrically connected to the first node, are formed in the well of N-type material. A third heavily doped region of N type material is formed in the first lightly-doped region of P-type material and is electrically connected to a reference node. In a first aspect of this invention, the third heavily doped region of N type material is formed in a second well of N-type material, which in turn is formed in the first lightly-doped region of P-type material. In this first aspect of the invention a further region of heavily doped P-type material is formed in the second well of N-type material, this further region of heavily doped P-type material being electrically connected to the reference node.
