  • Patent number: 5319550
    Abstract: The center of a reference mark is located by decreasing the range of pixel values defining an image defect. The pixel values defining the digital image are then enhanced to amplify the pixel values representing the reference mark and decrease the pixel values representing the background. The center of the digital image of the reference mark is determined from the altered image.

  • Patent number: 5317507
    Abstract: A method for storing and searching documents also useful in disambiguating word senses and a method for generating a dictionary of context vectors. The dictionary of context vectors provides a context vector for each word stem in the dictionary. A context vector is a fixed length list of component values corresponding to a list of word-based features, the component values being an approximate measure of the conceptual relationship between the word stem and the word-based feature. Documents are stored by combining the context vectors of the words remaining in the document after uninteresting words are removed. The summary vector obtained by adding all of the context vectors of the remaining words is normalized. The normalized summary vector is stored for each document. The data base of normalized summary vectors is searched using a query vector and identifying the document whose vector is closest to that query vector.

  • Patent number: 5305201
    Abstract: A system for monitoring play of a golfer (24, 26) comprises Location Information Transmitters (LIT) (54, 56) at predetermined locations within a golf course and a Mobile Electronic Transmitter/Receiver (METAR) (48, 50) carried in association with a golfer (24, 26) on a golf cart (28) or golf bag (32). A METAR (48) periodically transmits a METAR code over a restricted transmission range (300). In response to the METAR (48) being proximate to a LIT (54), LIT (54) receives the METAR code. After receiving the METAR code, LIT (54) transmits a play monitoring signal including its LIT code and the received METAR code to a Tracking Center (227) located in a clubhouse (22). Golf course personnel in the clubhouse (22) can monitor a display terminal (242) of the Tracking Center (227) and determine play of golfers (24, 26), use of golf carts (28, 34) and use of golf holes (10, 14).

  • Patent number: 5305200
    Abstract: A distributed processing on-line automated trading system uses structured messages to represent each stage in the negotiation between a market maker (quoter) and a potential buyer or seller (requestor). Such a system is subject to uncertainties caused by the fact that a variable time is required for an order (buy or sell) message to be transmitted from the requestor to the quoter, or for a cancel (quote interrupt) message to be transmitted from the quoter to the requestor. Furthermore, it is possible that an equipment failure in the network, either in a communication link or even at the workstation of one of the traders, will prevent a small fraction of such order messages and cancel messages from reaching their intended destination within the relatively short time-frame typically associated with an on-line transaction system.

  • Patent number: 5291402
    Abstract: An x-ray computed tomography system for helical scanning, translates a patient as projections of the patient at various beam angles are obtained and employs a detector array having multiple rows displaced along the direction of translation. The intensity signals from the multiple rows are combined to produce a composite projection having an improved beam profile along the translation direction. The composite projection is generated by adding together intensity signals obtained for detector elements in each column, at a given beam angle, and for related columns measuring rays having angles differing by x radians or an integer multiple thereof. The intensity signals are selected so that their points of acquisition cluster closely about the position of the desired slice plane.

  • Patent number: 5280429
    Abstract: A method and apparatus for displaying complex impedance and related physical characteristics of an object at a plurality of sinusoidal frequencies over a wide frequency range. Excitation signal waveforms are stored in digital form. Digital sampling and processing circuitry provide high noise immunity and accurate measurement at all impedance phase angles. The technique is particularly well-suited to the measurement of complex impedances in living biological tissue because the digital implementation results in highly accurate measurement values over a plurality of selectable frequencies within a wide sinusoidal frequency region. A novel adaptation of digital cross-correlation and convolution techniques is used to simultaneously display real and imaginary electrical impedance of living biological tissue at several selectable sinusoidal frequencies.

  • Patent number: 5272623
    Abstract: An improved method for executing a computer system novel software (SW) pram along with an enhanced series of five different data base logic tables that produce one or more tailored contracting documents (CDs) each with correctly selected Government Agency Regulation clauses (GARCs). In carrying out the method and producing any tailored CD, a multiline item (M/LI) multi-data field (M/DF) configuration table (CT) is formed when a user provides input data as well as from the data base selects categories and selectively answers questions. Then a M/LI M/DF logic test table (LTT) enables logic analysis either by itself as to any line item or in conjunction with a CT or a M/LI M/DF logic test results table (LTRT) all during a SW cycle (SWC). The SWC also permits analysis of certain test results of the LTRT prior to the LTRT coordinating with a logic test name table (LTNT) so as to enable formation of a M/LI M/DF pattern table (PT) having alpha-numeric identification of one or more correctly selected GARCs.

  • Patent number: 5255184
    Abstract: An airline reservation system implemented using a computer wherein reservations are controlled by a seat inventory control system. The inventory control system produces optimal reservation control using network-wide booking limits while taking into account the probabilistic nature of demand. The inventory control system, based on a concept termed Network-Based Expected Marginal Seat Revenue (EMSR), does not require the large number of variables required by the other network-based approaches, and it incorporates a probabilistic demand model without resorting to computationally intractable integer programming.

  • Patent number: 5229940
    Abstract: A method for generating a three dimensional velocity model from a grid of two dimensional lines is presented. Each of the two dimensional lines is common offset depth migrated and the migrated common offset sections are sorted into common image point (CIP) gathers. The proposed method examines all the common image point gathers from all the two dimensional lines and extracts out of plane three dimensional information. An initial three dimensional model is constructed from the two dimensional depth sections by mapping the depth images of several reflectors from each two dimensional line. Ray tracing through this initial three dimensional model, the out of plane three dimensional information is used to compute a set of corrections to the boundaries in the three dimensional model. The three dimensional model boundaries are then iterated until all mismatches are minimized.
