Architecture for extracting document information from documents received as search results based on a query string, and computing an edit distance between the data string and the query string. The edit distance is employed in determining relevance of the document as part of result ranking by detecting near-matches of a whole query or part of the query. The edit distance evaluates how close the query string is to a given data stream that includes document information such as TAUC (title, anchor text, URL, clicks) information, etc. The architecture includes the index-time splitting of compound terms in the URL to allow the more effective discovery of query terms. Additionally, index-time filtering of anchor text is utilized to find the top N anchors of one or more of the document results. The TAUC information can be input to a neural network (e.g., 2-layer) to improve relevance metrics for ranking the search results.

Systems and methods are provided for implementing error identification and evaluation for a Reed-Solomon (RS) error-correction code (ECC) system. The BMA algorithm and/or list decoding may produce one or more error locator polynomials that are related to a decision-codeword. An accelerated Chien search can be used to more quickly evaluate the one or more error locator polynomial. If the accelerated Chien search identifies a valid error locator polynomial, a normal Chien search can be used to identify error locations, and Forney's algorithm or an equivalent technique can be used to evaluate the error values. A RS ECC decoder can include a computation circuit that evaluates an error locator polynomial or an error evaluator polynomial. The computation circuit can include computation components that receive the coefficients of the polynomials.

An input device includes an optical waveguide, one or more light sources, one or more imaging sensors, and a translator. The optical waveguide has an input surface, a back surface substantially opposite the input surface, and a side surface therebetween. The input surface has a plurality of different input locations. The one or more light sources are positioned to introduce light into the optical waveguide. A distortion of each different input location of the input surface causes a portion of light within the optical waveguide to exit from the optical waveguide at a different escape location of the side surface. The one or more imaging sensors are positioned and aimed to detect an escape location of a portion of light exiting from the side surface. The translator determines an input location corresponding to the escape location for each detected escape location.

Systems and methods are provided for implementing various aspects of a Reed-Solomon (RS) error-correction system. A detector can provide a decision-codeword from a channel and can also provide soft-information for the decision-codeword. If the decision-codeword corresponds to an inner code and an RS code is the outer code, a soft-information map can process the soft-information for the decision-codeword to produce soft-information for a RS decision-codeword. A RS decoder can employ the Berlekamp-Massey algorithm (BMA), list decoding, and a Chien search, and can include a pipelined architecture. A threshold-based control circuit can be used to predict whether list decoding will be needed and can suspend the list decoding operation if it predicts that list decoding is not needed.

The invention relates to a system and method for attenuating harmonics in output signals. In the system, an electronic circuit for reducing harmonics of an output signal from a power amplifier in a transmission circuit for a wireless communication device is provided. The circuit comprises: a printed circuit board (PCB); a power amplifier for generating an output signal; and a circuit implemented on the PCB connected to an output terminal of the power amplifier for the output signal. The circuit comprises a first filtering stage; a delay element; and a harmonic filter. The delay element is located between the harmonic filter and the output terminal and the delay element provides a timing delay in the output signal through at least one 0 ohm-rated component. Also, the harmonic filter is a low pass filter having a frequency cut-off point that attenuates first order harmonics of the output signal.

In general, the present invention, and in various exemplary embodiments, provides a chemical management information system and methods of using the same. The chemical management system captures chemical use on an on-going and real-time basis regardless of the source of data. The chemical management system integrates chemical usage information by user input and from a plurality of sources. It also allows for the evaluation of a chemical in minutes rather than days, and further allows a user to submit this information to the governing body requiring the information in a simple step. In one embodiment, the chemical management system comprises a web-based use capture tool, a compliance tool, a safety database search tool, and a gap analysis tool.
