  • Patent number: 4991092
    Abstract: An imaging technique is disclosed for enhancing the contrast of an image, in particular for enhancing the contrast between subregions of a region of interest which may have similar signal characteristics and significantly distinct physical properties. A distribution density function describing the density of the signal in a signal space assigned to a voxel of the region to be imaged is first computed. This distribution function is then convolved with a resolution function, preferably a Gaussian function. Advantageously, the variance of the Gaussian is greater and a multiple of the variance of the noise statistics of the input image. The result of the convolution of the distribution function with the resolution function defines a scale, preferably a grey scale which assigns a particular tone to a pixel of the image corresponding to the voxel of the region to be imaged. The standard deviation is preferably chosen by the user and defines the resolution of the final image in the signal space.

  • Patent number: 4989142
    Abstract: Three-dimensional images are formed from tomographic data collected such that each two-dimensional slice is tilted with respect to the transverse slice direction. Geometric distortion in the reconstructed 3-D image caused by the slice tilt is removed either during extraction of the 3-D surface from the tomographic data or during rendering of the final surface using a matrix transformation.

  • Patent number: 4984178
    Abstract: A chart parser is disclosed which incorporates rule and observation probabilities with stochastic unification grammars. The parser operates frame synchronously to provide top-down hypotheses and to incorporate observation probabilities as they become available. Because the language model produces multiple explanations of the speech data between frames, the prediction and combination of rules may create cycles in a graph representing the best scores. Score calculation includes the detection of these cycles and propagation of the best scores to the next frame. The algorithm creates no more states than a nonprobilistic chart parser, and remains linear for regular grammars and cubic in the worst case for CFGs. The parser allows a direct integration of statistical speech information and linguistic constraints within the same language model, while the language model permits a generalization of HMM-type models. The efficiency of the parser makes it applicable to multiple levels of a spoken language system (e.g.

  • Patent number: 4975843
    Abstract: An array processor has been designed in a highly paralleled fashion thereby allowing extremely fast movement of data. Two 32-bit words come out of an internal data memory device. This data is fed into a register file. On the same clock cycle, three 32-bit results are coming out of an arithmetic unit. Those results feed back into the register file. Therefore, on a single clock cycle, five separate pieces of data are going into the register file. In the same clock cycle, other data coming out of the outputs of the register file feed data into two separate floating arithmetic adders and one floating arithmetic multiplier. The design of the present embodiment allows a constant flow of data to be supplied to the arithmetic unit thereby using the arithmetic unit to its maximum functioning ability.

  • Patent number: 4974160
    Abstract: A system and method are disclosed for computer implementation of products wherein a designer examines the products desired by an institution planner and identifies functions ("components") collectively common thereto. The designer proceeds to define component processes collectively common to such components and categorizes code for this purpose in groupings selectable (executable) by the planner upon system installation and subsequently changeable as desired. The component process selections of the planner are recorded and the system is thereby defined in its aspect which is accessible to the planner. The designer works from such definitions of all components and component processes obtained from discussion with system planners prior to installations to define component subprocesses collectively common to the component processes and identifies combinations of component subprocesses in various sequences to realize component processes.

  • Patent number: 4967345
    Abstract: A least weight route computation algorithm for use in computing routes through a data communications network is improved by recording the number of equally weighted paths to a particular node through different predecessor nodes. If a route must be selected to the particular node, the relative numbers of equally weighted routes through different predecessor nodes determines the probability with which a route will be selected through the particular predecessor node.

  • Patent number: 4962452
    Abstract: A machine translation system is capable of automatically and correctly analyzing a sentence having an inserted comment of a first language by means of a specific dictionary. The dictionary includes a first dictionary in accordance with which the inserted comment is extracted and analyzed and a second dictionary in accordance with which the other portion of the sentence than the inserted comments is analyzed. An analysis of the inserted comment and an analysis of the other portion are combined to obtain an analysis of the overall sentence. The translated sentence in the second language is produced in accordance with the analysis of the sentences which is combined. Furthermore, the translated inserted comment is displayed in a distinguishable manner. Specifically, a symbol for showing the inserted comment is added to the translated inserted comment. The translated sentence is displayed for including the inserted comment with the symbol.

  • Patent number: 4959788
    Abstract: An IC card transaction system is disclosed in which at least a portion of the data required to complete a transaction processing is stored in the card by a customer in advance of transaction processing. A skip code is entered for portions of transaction data that is not pre-stored. An automatic transaction processing unit reads the transaction data stored in the card and receives from the customer any additional data which was not previously stored in the card (e.g. data associated with the skip code) and which is required to complete a transaction.

  • Patent number: 4958282
    Abstract: An image reconstruction method of the 3DFT type is proposed wherein the organization of the excitation and measuring sequences comprises the repetition of macro-sequences. During the macro-sequences, a selection encoding gradient which may have a small number of encoding steps (in particular, smaller than the expected resolution of the images) is applied. It is shown that this approach enables the best possible of the power and flexibility of the vectorial processors used to perform image reconstruction computations efficiently. It is shown that the images can then be produced in real time.

  • Patent number: 4953087
    Abstract: Three-dimensional representations of the surface of a structure located in a three-dimensional space are formed from tomographic data collected in a medical diagnostic imaging system. The images include structures of specific interest displayed at a high resolution and adjacent structures to improve the perception of the structures of interest displayed at a low resolution. Total examination time is reduced because the total number of slices needed to form the image is reduced. A plurality of slices of different spacings are obtained and divided into first and second space portions (associated with different slice spacings). An interpolation factor which varies as a function of slice spacing is used in the dividing step to establish selected dimensions of first and second three-dimensional elements.

  • Patent number: 4953088
    Abstract: A translation apparatus is provided for translating a sentence from an original language into a sentence of a target language. The translation apparatus has a computer which analyzes the original language sentence, and generates the target language sentence based on the analyzed original language sentence. During the translation, indicators are displayed on a screen for indicating that the analysis of the original language sentence is taking place, and other indicators are displayed for indicating that the generation of the target language sentence is taking place. These indicators will help the operator to know that the translation apparatus is properly operating for obtaining a translation result, particularly when the translation process is taking a long time.
