| 20100199206 | WEB BROWSER WITH MULTILEVEL FUNCTIONS - A architecture is provided to enable a client web browser to conduct and manage a multilevel search. The browser includes an application layer interface. The application layer interface is for coupling to network via a protocol stack. The browser also includes a markup language parser. The parser receives information from the application layer interface. The browser also includes a graphical user interface for interacting with a user. The graphical user interface allows a user to specify a set of multilevel search parameters. The browser also includes a markup language processor that receives input from the markup language parser and multilevel search parameters from the graphical user interface. The markup language processor conducts and manages a multilevel search to find specified information on a current web page or a web page referenced by the current web page in accordance with a parameterized search tree. The present invention also enables an automatic processes to print sets of linked web pages and to generate sitemaps, filtered sitemaps, filtered results pages in accordance with user specifications. | 08-05-2010 |
| 20090119417 | FEDERATED MULTIPROTOCOL COMMUNICATION - Methods, apparatus, and business techniques are disclosed for use in distributed communication systems comprising a plurality of communication protocols. In one embodiment a first air interface is used to initiate communication between a wireless client and a remote server at least partially using a first wireless access point. The server sends the wireless client a stub of a distributed object. The stub is used to instantiate an object class. The object class defines an interface that the remote client can use to communicate with the remote server using an upper layer interface. The distributed object stub also provides an implementation of a software radio configuration for a set of lower protocol layers in a second air interface. The wireless client can thereby communicate with a second wireless access point using said second air interface protocol. Exemplary embodiments of the present invention are disclosed that focus on toll-tag and electronic-commerce related highway systems, distributed federated wireless access systems, and wide area wireless system capacity augmentation. | 05-07-2009 |
| 20090116576 | REDUCED COMPLEXITY MULTICARRIER PRECODER - A reduced complexity precoder provides an efficient method and structure to precode a vector-signal-point sequence for transmission through a band-limited channel. The precoder enables a block-oriented receiver to recover an underlying data stream in the presence of inter-symbol interference and noise. The precoder structure is applicable to multicarrier systems such as DMT (discrete multitone) or related transform domain and vector communication systems. The inventive precoder reduces the cost of precoding by an order of magnitude and eliminates the need for a cyclic prefix in DMT and related communication systems. Related multicarrier transmitter and receiver structures and methods which reduce computation, increase transmission bandwidth and reduce transmission power are also developed. | 05-07-2009 |
