Abstract: A multiple network protocol encoder/decoder comprising a network protocol layer, data handler, O.S. State machine, and memory manager state machines implemented at a hardware gate level. Network packets are received from a physical transport level mechanism by the network protocol layer state machine which decodes network protocols such as TCP, IP, User Datagram Protocol (UDP), PPP, and Raw Socket concurrently as each byte is received. Each protocol handler parses and strips header information immediately from the packet, requiring no intermediate memory. The resulting data are passed to the data handler which consists of data state machines that decode data formats such as email, graphics, Hypertext Transfer Protocol (HTTP), Java, and Hypertext Markup Language (HTML).

Abstract: An authoring tool allows users to create complex documents from a base division model, the model includes a plurality of pointers allowing the divisions to be interconnected to one another dynamically to create a complex hierarchy of divisions, including nested divisions. The content of a division may be located externally to the actual document and authoring tool system. A display mechanism is further disclosed for instantaneously determining the division name and page number within a document from a graphic user display.

Abstract: A single file holds multiple versions of a document composed of an interconnection of objects which themselves have versions and are stored in the file. When the document is changed by changing any of the interconnected objects, a check is first made to determine whether the object version is same as the document version currently being edited. If not, a copy of the object is made and saved. Any version of the document can be reconstructed by interconnecting object versions which have a highest level which is equal to, or less than, the desired document version. Therefore, only objects which are changed are duplicated and copies of objects are only made when an object changes. The interconnection of the objects to form structure of the document is maintained by an interconnection of object pointers. Each object has an associated demand loader object which includes a list of object versions for the associated object plus a pointer to one of the versions.
