Abstract: A method and system for preventing a timeout from reaching a network host when bringing up a down link that is slow to waken. The method generally comprises receiving a request to access an information. If a link along a path to a remote computer containing the information is down, the link is established while concurrently returning a plurality of imposter responses, such as domain names, until the network link is established. Software implementing this method may be stored and executed in any network host. This method is particularly advantageous when waiting for a dial-up telephone connection to a network to be established.

Abstract: A system and method for rapidly identifying the existence and location of an item in a file using an improved hash table architecture. A hash table is constructed having a plurality of hash buckets, each identified by a primary hash key. Each hash entry in each hash bucket contains a pointer to a record in a master file, as well as a secondary hash key independent of the primary hash key. A search for a particular item is performed by identifying the appropriate hash bucket by obtaining a primary hash key for the search term. Individual hash entries within the hash bucket are checked for matches by comparing the stored secondary keys with the secondary key for the search term. Potentially matching records can be identified or ruled out without necessitating repeated reads of the master file. The improved hash table system and method is employed in a contextual text searching application for determining the intersection of a text search with a hierarchical categorization scheme.

Abstract: A power function is approximated over an applicable data interval with polynomials determined by means of a Chebyshev minimax approximation technique. In some cases, multiple polynomials may be used to approximate the function over respective ranges of the desirable interval, in a piecewise manner. The appropriate polynomial that approximates the power function over the range of interest is derived and stored. When the power function is to be applied to a particular data value, the data value is first evaluated to determine where it lies within the applicable interval. The constants for the polynomial associated with that range of the interval are then retrieved and used to calculate the power of that data value.

Abstract: An automatic file clustering algorithm enables documents within a file system to be displayed in a semantic view. The file clustering algorithm maps all words and documents into an appropriate semantic vector space, clusters the documents at a predetermined level of granularity, and assigns a meaningful descriptor to each resulting cluster. The documents are displayed to the user in a hierarchy in accordance with the resulting clusters. This results in a virtual file system with a semantic organization, that allows the user to navigate by content.

Abstract: A centralized queue for a network printing system allows clients to make job requests and be placed in a job queue without transmitting the actual print job data to the network. An imaging device protocol (IDP) operates independently of the network layers below and only requires that a transport protocol/port be bidirectional. A variety of heterogenous network protocols may be supported by IDP for placing all of the incoming print job information in a print queue regardless of the protocol. Print job information from both IDP and non-IDP protocol/ports may be placed in the print queue by emulating IDP on the non-IDP protocol/ports. As a result, job information for all of the print jobs attempting to access a busy printer may be stored in the print queue so that the print jobs can be printed by the printer with a fair arbitration once the network printer becomes available.

Abstract: Method and means for controlling the execution sequence of a first sequence of modules in a first task. The first sequence of modules are linked to one another and have at least one sequence of execution. The method stores in each of the first sequence of modules a skip value representing which of subsequent modules to execute. The method executes the first of the first sequence of said modules, and then executes the next of the modules indicated by the skip value. Conservation of processor bandwidth is accomplished by avoiding the loading of modules which will not be executed. Method and means are further provided for simultaneous activation/deactivation of a set of tasks by a processor, each of the tasks normally executed in a sequential fashion by one or more processors. A list of tasks to be activated/deactivated is stored, including the timing relationship for the activation process. The list is then implemented as frame numbers for activation and requested state in the actual task list.

Abstract: One embodiment of the present invention provides a system that facilitates pipelining cache coherence operations in a shared memory multiprocessor system. During operation, the system receives a command to perform a memory operation from a processor in the shared memory multiprocessor system. This command is received at a bridge that is coupled to the local caches of the processors in the shared memory multiprocessor system. If the command is directed to a cache line that is subject to an in-progress pipelined cache coherency operation, the system delays the command until the in-progress pipelined cache coherency operation completes. Otherwise, the system reflects the command to local caches of other processors in the shared memory multiprocessor system. The system then accumulates snoop responses from the local caches of the other processor and sends the accumulated snoop response to the local caches of other processors in the shared memory multiprocessor system.

Abstract: A voice menu system is disclosed. The present invention generally allows for updateable audio menus. Although a device might have some pre-packaged menu components, other menu components can be received from a server. Each menu component, regardless of whether it is original or received from the server, has an associated voiced name. When a user highlights a menu choice, the voiced name can be played. The user then has the option of selecting the menu choice or scrolling to a new menu choice. In this way, a user could navigate the menu without having to actually see a visual display of the menu, which may be especially useful for users unable to see the visual display or users with visual disabilities.

Abstract: Methods and apparatus for spreading and concentrating information to constant-weight encode of data words on a parallel data line bus while allowing communication of information across sub-word paths. In one embodiment, data transfer rates previously obtained only with differential architectures are achieved by only a small increase in line count above single ended architectures. For example, an 18-bit data word requires 22 encoded data lines for transmission, where previously, 16 and 32 lines would be required to transmit un-coded data with single-ended and differential architectures respectively. Constant-weight parallel encoding maintains constant current in the parallel-encoded data lines and the high and low potential driver circuits for the signal lines.
