A method and system for facilitating a keyword search request initiated at a client station within a multilevel data network, wherein the multilevel data network includes multiple local sites each containing multiple data pages. Multiple keywords from each of the data pages within the local sites of the multilevel data network are stored locally and indexed such that each of the keywords points to one or more of the data pages in which the keywords are contained. The keywords and their index associations are locally updated. A central database is utilized to compile and index the locally indexed keywords from each of the local sites, such that each of the keywords in the central database points to one or more local sites from which those keywords came in response to a keyword search initiated at the client station.

Virtual architecture and instruction set for parallel thread computing
ActiveUS20080184211A1Improve developmentImprove portabilityProgram control using stored programsSoftware engineeringApplication softwareData sharing
A virtual architecture and instruction set support explicit parallel-thread computing. The virtual architecture defines a virtual processor that supports concurrent execution of multiple virtual threads with multiple levels of data sharing and coordination (e.g., synchronization) between different virtual threads, as well as a virtual execution driver that controls the virtual processor. A virtual instruction set architecture for the virtual processor is used to define behavior of a virtual thread and includes instructions related to parallel thread behavior, e.g., data sharing and synchronization. Using the virtual platform, programmers can develop application programs in which virtual threads execute concurrently to process data; virtual translators and drivers adapt the application code to particular hardware on which it is to execute, transparently to the programmer.

ActiveUS7215721B2Efficient processingMinimizes average error probabilityRepeater/relay circuitsDc level restoring means or bias distort correctionNormal densityAutomatic control
A multilevel optical receiver can comprise a plurality of comparators that generally correspond with the number of levels in a multilevel data stream. Each comparator can be individually controlled and fed a decision threshold in order to decode a multilevel signal. The multilevel optical receiver can generate a statistical characterization of the received symbols in the form of a marginal cumulative distribution function (CDF) or probability density function (pdf). This characterization can be used to produce a set of ε-support estimates from which conditional pdfs are derived for each of the transmission symbols. These conditional pdfs may then be used to determine decision thresholds for decoding the received signal. The conditional pdfs may further be used to continuously estimate the fidelity or error rate of the received signal without the transmission of a testing sequence. The ε-supports may further be used to automatically control the gain on the receiver.

A mutable multilevel data structure representing a graph structure may include multiple read-only levels and a single writable level.

A hybrid variant may switch between a performance-optimized variant (whose edge tables include complete adjacency lists for vertices whose edge sets were modified) and a space-optimized variant (whose edge tables include only newly added adjacency list elements). The vertex tables and / or the writable level may be implemented using copy-on-write arrays, each including an indirection table and multiple fixed-sized data pages. Computations may be run on the read-only levels or on the writable level and read-only levels.

Multilevel data encoding and modulation technique
ActiveUS7221711B2Improve discriminationImprove anti-interference abilityPulse conversionAmplitude-modulated carrier systemsHarmonicPeak value
The multilevel data encoding and modulation technique uses a pair of complementary logic sets. In its most basic form, the sets are binary sets each containing a line level for a logical one and a line level for a logical zero for a total of four logic levels. The encoding technique requires a polar change in the line level after every bit. An optional fifth level may be used in order to skew the frequency or to enable automatic gain control circuitry to ensure consistent level discrimination. The encoding technique may be used in a bipolar device, or a bias level may be applied to the signal for unipolar transmission. The encoding technique involves inverting the polarity of alternating bits, filtering out all odd harmonics, transmitting and receiving the waveform, and decoding the demodulated waveform by comparing the absolute value of the half-cycle peak-to-peak voltage gain to a predetermined table.
