An apparatus and method for obtaining facies of geological formations for identifying mineral deposits is disclosed. Logging instruments are moved in a bore hole to produce log measurements at successive levels of the bore hole. The set of measurements at each such level of the bore hole interval is associated with reference sample points within a multidimensional space. The multidimensional scatter of sample points thus obtained is analyzed to determine a set of characteristic modes. The sample points associated with characteristic modes are grouped to identify clusters. A facies is designated for each of the clusters and a graphic representation of the succession of facies as a function of the depth is thus obtained. To identify the clusters, a "neighboring index" of each log measurement point in the data set is calculated. Next, small natural groups of points are formed based on the use of the neighboring index to determine a K-Nearest-Neighbor (KNN) attraction for each point. Independently of the natural group formation, an optimal number of clusters is calculated based on a Kernel Representative Index (KRI) and based on a user-specified resolution. Lastly, based on the data calculated from the prior steps, final clusters are formed by merging the smaller clusters.

An apparatus and method to detect a blood flow signal free from a motion artifact, and a stress test apparatus using the same, enhance data reliability of the blood flow signal by removing the motion artifact from the blood flow signal detected by photo-plethysmography. The apparatus to detect the blood flow signal includes a base pattern correlation coefficient calculating unit to determine peak points in the blood flow signal sensed from a body of an examinee using a blood flow sensing unit, and to calculate correlation coefficients of each peak point using a predetermined base pattern, and a motion artifact processing unit to determine the motion artifact using the calculated correlation coefficients and to remove the motion artifact from the blood flow signal. Thus, reliability of the blood flow signal is enhanced by effectively removing the motion artifact from the blood flow signal detected by the photo-plethysmography.

A unified context-aware content archive system allows enterprises to manage, enforce, monitor, moderate, and review business records associated with a variety of communication modalities. The system may store an information infoset derived or inferred from one or more documents representing communications according to the variety of communication modalities as interaction transcripts. An interaction transcript represents interactions between participants through the documents rather than the documents themselves allowing for derivation or inference of communication events, chronologies, and mappings to be stored in a common data structure. In one aspect, events correlation is provided between participants of communications that can be established by general time series analysis for the purposes of extracting meaningful statistics and interaction contexts and other characteristics of data. In another aspect, chronological mappings are provided of conversations between an established start and end time frame.

A centralized master repository contains the reference data, the reference data being associated with multiple schemas, each schema including one or more data models for reference data, each data model including one or more fields. A data management services framework coupled to the repository provides services for managing the reference data in the repository. The services framework supports a master schema including a union of multiple models and associated fields in the multiple schemas. The services framework also supports a thesaurus including, for each field in the master schema, a set of synonyms each representing a mapping between the field in the master schema and a corresponding field in a particular one of the multiple schemas. The master schema and thesaurus facilitate centralized management of the reference data in the repository across multiple heterogeneous external operational systems that have different associated data models and are provided indirect access to the reference data in the repository for operational use of the reference data according to associated business workflows.

A system for pattern dependent equalization has an equalizer bank and a detector. The equalizer bank has a plurality of equalizers, which are each tuned to a selected data pattern. The detector may be a standard sequence detector or a modified Viterbi detector, which calculates the branch metric using a pattern dependent equalized output and a pattern-dependent target. A method of decoding data uses a pattern dependent equalizer bank. The pattern dependent equalizer bank processes a segment of a bit sequence to produce an equalized pattern-dependent output for each equalizer in parallel. The detector then detects the bit sequence using the branch metric calculation to select the smallest accumulated path metric.

The detection system and method may thus mitigate the effects of data pattern dependent signal distortion.

A pattern matching system includes, in part, a multitude of databases each configured to store and supply compressed data for matching to the received data. The system divides each data stream into a multitude of segments and optionally computes a data pattern from the data stream prior to the division into a multitude of segments. Segments of the data pattern are used to define an address for one or more memory tables. The memory tables are read such that the outputs of one or more memory tables are used to define the address of another memory table. If during any matching cycle, the data retrieved from any of the successively accessed memory tables include an identifier related to any or all previously accessed memory tables, a matched state is detected. A matched state contains information related to the memory location at which the match occurs as well as information related to the matched pattern, such as the match location in the input data stream.

A method for determining the root causes of fail patterns in integrated circuit chips is provide wherein a known integrated circuit chip layout is used to identify a plurality of potential defects and a plurality of potential fail patterns in the integrated circuit chip. Correlations between the potential defects and the potential fail patterns that result from those defects are identified. Based on this identification, the potential fail patterns are grouped by common potential defect. An actual integrated circuit chip that is manufactured in accordance with the test layout is tested for failure patterns. These failure patterns are then compared to the groupings of potential fail patterns. When a match is found, that is when a given group of fail patterns is found in the actual integrated circuit chip, then the potential defect associated with the potential fail patterns to which the actual fail patterns are matched is identified. This defect is the root cause of the failure pattern in the actual chip.

Methods, systems, and apparatuses provide dynamic creation and modification of wafer test maps. Test plans are defined for a testing session of a wafer lot. The test plan is associated with a number of seed map patterns. During a wafer lot testing session, test results are dynamically obtained and examined at run-time of a test. Moreover, the seed map patterns are overlaid on the test sites defined in the test plan. If the test result statistics are outside of defined threshold tolerance levels, then a new wafer test map is created or modified at run-time, according to corresponding seed map patterns. If seed map patterns are within the intersection of valid test sites, then seed map patterns are created at run-time.

A technique to collect measurements that are adapted to a signal / scene of interest is presented. The measurements are correlations with patterns that serve as modulating waveforms. The patterns correspond respectively to rows of a sensing matrix. The method uses a sensing matrix whose rows are partitioned into blocks. Each block corresponds to a distinct feature or salient property of the scene. For each block, the method collects a number of measurements of the signal / scene based on selected rows of the block, and generates one or more associated statistics for the block based on said measurements. The statistics for the blocks are then analyzed (e.g., sorted) to determine the most important blocks. Subsequent measurements of the signal / scene may be based on rows from those most important blocks. The original measurements and / or the subsequent measurements may then be used in an algorithm to reconstruct the signal / scene.

This will enable the efficient dispatch of spare parts and service personnel to the location where the failure has occurred.
