Abstract: A system and method for deriving a large-span semantic language model for a large vocabulary recognition system is disclosed. The method and system maps words from a vocabulary into a vector space, where each word is represented by a vector. After the vectors are mapped to the space, the vectors are clustered into a set of clusters, where each cluster represents a semantic event. After clustering the vectors, a probability that a first word will occur given a history of prior words is computed by (i) calculating a probability that the vector representing the first word belongs to each of the clusters; (ii) calculating a probability of each cluster occurring in a history of prior words; and weighting (i) by (ii) to provide the probability.

Abstract: A minimal instruction set computer architecture (hyperscalar computer architecture) comprises a central memory, an instruction buffer, a control unit, an I/O control unit, a plurality of functional units, a plurality of register files, and a data router. In the hyperscalar computer architecture, the central memory transfers a plurality of instructions to the instruction buffer. The control unit receives multiple instructions from the instruction buffer, and automatically determines and issues the largest subset of instructions from those received that can be simultaneously issued to the plurality of functional units. Each functional unit receives data from and returns computational results to a corresponding register file. The data router serves to transfer data between each register file and any other register file, the central memory, the control unit, or the I/O control unit.

Abstract: A method for arbitrating display output on a display device of a computer system comprises comparing a candidate display area with each rendering display area in a rendering collection and each waiting display area in a waiting collection, and determining whether at least one dependency exists for the candidate display area based on the comparing step, wherein the candidate display area is placed in the waiting queue when at least one dependency exists. The method further includes placing the candidate display area in the rendering collection when the at least one dependency does not exist. The method of arbitration includes releasing the current rendering display area.

Abstract: A system and method of compensating for the effects of aging of phosphors and faceplate upon color accuracy in cathode ray tubes, wherein beam current measurements are made upon individual cathodes of a cathode ray tube to sample the individual beam currents at periodic intervals. The sum-totals of the individual beam current measurements are then stored in a non-volatile memory location. Correction factors are calculated for both luminous efficiency degradation and for deviations in hue, based on the stored sum-total beam current measurements in combination with empirically-derived formulae. These correction factors are then used to calculate corrected tristimulus values X, Y, and Z. The corrected tristimulus values are used to calculate the amount of beam current necessary to compensate for color degradation of the cathode ray tube.

Abstract: Improved method and apparatus for vector quantization (VQ) to build a codebook for the compression of data. The codebook or "tree" is initialized by establishing N initial nodes and creating the remainder of the codebook as a binary codebook. Children entries are split upon determination of various attributes, such as maximum distortion, population, etc. Vectors obtained from the data are associated with the children nodes, and then representative children entries are recalculated. This splitting/reassociation continues iteratively until a difference in error associated with the previous children and current children becomes less than a threshold. This splitting and reassociating process continues until the maximum number of terminal nodes is created in the tree, a total error or distortion threshold has been reached or some other criterion. The data may then be transmitted as a compressed bitstream comprising a codebook and indices referencing the codebook.

Abstract: A media ejection system includes a peripheral unit having a housing, an ejection mechanism, and a memory wire coupled to the ejection mechanism. The system further includes a digital processor for issuing ejection commands, and a controller responsive to the ejection command for controlling a current flow through the memory wire. When sufficient current flows through the memory wire, it contracts to activate the ejection mechanism, thereby ejecting a removable medium (such a PCMCIA card) from the housing of the peripheral unit. A method of the invention includes the steps of receiving an ejection request, issuing a ejection command in response to the ejection request, where the ejection command includes parameters for controlling current flow through the metal alloy, and electrically energizing the memory alloy in accordance with the parameters such that the memory alloy undergoes a dimensional change to activate a removable medium ejection mechanism.

Abstract: A computer performs designated operations on text that can be in any of a variety of different languages, rather than being restricted to a single language for which the computer was designed. A library stores operators and functions that can act upon character strings. Also stored within the library are sets of rules which identify the casing, ordering and matching of characters within different writing systems, or human languages. When a user of the computer designates a particular operation to be performed with respect to a text string, the writing system associated with the text string is identified. This identification can be made with reference to the typefont that is used to display the text string. Once the writing system for a string has been determined, appropriate tables and data structures that define and encode language rules for that writing system are accessed and applied to the operation on the string.

Abstract: Hyperlinear chromosomes are arrays of parameters stored in a computer readable memory, for use in implementing a genetic algorithm. Each chromosome may represent the mapping of a problem, including physical parameters, onto constituent genes which are addressed in memory as multiple, intersecting vectors in n-dimensions, where n is >2. A computing system is adapted to perform hyperlinear crossover, reproduction and fitness evaluation on the hyperlinear chromosomes. An adaptive computing system produces optimized control signals based on the attainment of a desired level of fitness of one or more hyperlinear chromosomes.
