Abstract: Systems and methods for online content syndication using high-performance matching and filtering for structured and semi-structured rules in real-time are disclosed. In one embodiment, the system provides a marketplace for publishers, editors and advertisers. It can harness the power of the Internet and XML to facilitate the sale and acquisition of articles, photos and graphics each with their own licensing rules. In one embodiment, the system provides a unique and powerful licensing engine that gives control over price, licensing rules, embargoes and exclusions across content—with an ability to adjust those rules for each individual asset. In one embodiment, the system combines advanced data management technology, a sophisticated search engine and e-commerce technologies to provide a novel solution to the syndication of content.

Abstract: A method and apparatus for optimizing a system for transmitting a layered modulated signal is disclosed. The method comprises the steps of defining the system in terms of a set of system parameters, including an optimal power separation S between a power of a first modulation layer and a power of a second modulation layer and a required system carrier-to-noise ratio (CNRS), determining an optimal power separation S to minimize the error rate of a lower layer modulated signal BERL, and selecting the remaining system parameters in the set of system parameters using the determined optimal power separation S.

Abstract: A method and apparatus for equalizing digital data signals is disclosed. The method comprises the steps of demodulating and decoding an input signal having input data to produce a data output, remodulating the data output to produce a training sequence including an idealized input signal, wherein the training sequence is comprised of adjacent symbols in the input data, and generating equalizer parameters from the training sequence. The apparatus comprises a demodulator (for demodulating an input signal to produce a data output), a modulator communicatively coupled to the demodulator (for remodulating the data output to produce a training sequence including an idealized input signal wherein the training sequence is comprised of adjacent symbols in the input data), and a parameter generation module communicatively coupled to the modulator (for generating equalizer parameters from the training sequence).

Abstract: A simplified scrambling scheme that unifies all signals of a satellite broadcasting system, including frame header (404), frame body (402) and pilot symbols (408) with a common reference phase. This results in the simplification and increased flexibility of the receiver front-end design without affecting the overall system performance. In many current communications systems with frame headers and pilot symbols, the phases of frame headers and pilot syrnbols are not designed to be aligned with any constellation points of the modulated data from the frame body. This scrambling scheme takes into account possible impact due to irregular phase changes between frame headers/pilot symbols and modulated data.

Abstract: A system and method for assigning attributes to XML document nodes to facilitate their storage in relational databases and the subsequent retrieval and re-construction of pertinent nodes and fragments in original document order is provided. Since these queries are performed using relational database query engines, the speed of their execution is significantly faster than that using more exotic systems such as object-oriented databases. Furthermore, this method is portable across all vendor platforms, and so can be deployed at client sites without additional investments in database software.

Abstract: A method and apparatus for equalizing digital data signals is disclosed. The method comprises the steps of demodulating and decoding an input signal having input data to produce a data output, remodulating the data output to produce a pseudo-training sequence including an idealized input signal, and generating equalizer parameters from the pseudo-training sequence. The apparatus comprises a demodulator for demodulating an input signal to produce a data output, a modulator, communicatively coupled to the demodulator, for remodulating the data output to produce a pseudo-training sequence including an idealized input signal, and a parameter generation module, communicatively coupled to the modulator for generating equalizer parameters from the pseudo-training sequence.

Abstract: Data at a transmitter is modulated, in accordance with instructions from a receiver, to provide M different modulations in successive sequences. N spreading codes are also provided in successive sequences at the transmitter, in accordance with instructions from the receiver, alternately with the M data modulations. The alternate sequences of the M data modulations and the N spreading codes are paired and individual ones of the M data modulations and the N spreading codes in the paired sequences are combined (e.g. multiplied). Alternatively, an individual one of the M data modulations is combined (e.g. multiplied) with an individual one of the N spreading codes in the adjacent sequence. The modulator and the spreader may be included at the transmitter with (a) a channel encoder which provides channel coding in accordance with instructions from the receiver, (b) a puncturer which removes particular data in accordance with instructions from the receiver and (c) an interleaver.

Abstract: A method is provided for processing tree like data structures in a streaming manner. An initial context of name/value bindings is set up. A tree of objects is constructed. Each element in the tree of objects is represented as a function object that accepts a context parameter and a target parameter that it can send a stream of start, content, and end events to represent tree output. The parse tree of objects is examined for element names that are recognized as commands. The commands are converted to special function objects that implement command's semantics. Other elements, that are not recognized as commands, are mapped to a default function object.

Abstract: A simplified “T” interchange design is provided for an intersection of a four lane expressway with a two lane highway. The design uses one, short, two lane bridge over two lanes of traffic. The design would be very inexpensive to build when compared to the cost to build a conventional interchange. The design would be very safe for vehicles passing through the interchange from any direction. Vehicles are never required to cut across lanes of high speed traffic when making transitions between the two lane highway and the expressway.

Abstract: The current invention relates to an active factor present in homogenized brain tissue which inhibits antigen-driven proliferation of lymphocytes in culture, but stimulates proliferation in response to most mitogens. The inhibitory activity can be destroyed by treatment with proteases or neuraminadase. The activity is in the insoluble fraction of the homogenate, but becomes soluble in 0.04 M NaOH. After gel filtration chromatography of the NaOH soluble material, the suppressive activity is in the high molecular weight fraction which elutes in the void volume of the column. This fraction contains protein and carbohydrate. The activity is not affected by neutralizing antibodies against regulatory cytokines, does not depend on Fas or FasL, and is not due to the presence of gangliosides. These data suggest that a brain glycoprotein which is either membrane-bound or part of the extracellular matrix has powerful immune regulatory effects in culture.
