  • Patent number: 5892681
    Abstract: An automated system for partitioning a set of Boolean logic equations onto one or more devices selected from a plurality of commercially available devices. The system utilizes a processor having a memory containing information on the different architectural types of devices, physical device information on individual devices and user generated design constraints, weighting factors and partitioning directives. Based upon this stored information, the system of the present invention selects all acceptable architectural types of devices wherein at least one of the Boolean logic equations can be placed thereon. For all physical devices associated with the acceptable architectural types only those devices which fall within the selected user constraints are selected. The system then evaluates the weighting factors to order the devices in order of cost value and then fits the equations according to the partitioning directives to the devices.

  • Patent number: 5706208
    Abstract: A method for predicting a property of a matter of biological origin, such as biological fluid, containing water, where the biological matter may be approximated to contain two compartments where one compartment has a proportionally larger or smaller amount of water than the other compartment having the property of interest. The method establishes a training set in the near-infrared (NIR) region with independent quantification of the property of the matter using known techniques. The training set is mathematically analyzed according to a correlation developed by regression analysis after employment of a ratio pre-processing technique. The result is a mathematical transformation equation which quantitatively relates spectral intensities at specific wavelengths to the property of interest. This transformation equation may be applied to unknown samples so as to predict their properties, thereby eliminating need for the reference method except for validation or recalibration.

  • Patent number: 5299118
    Abstract: An analysis system accepts physiological sensor signals, including electroencephalogram (EEG) and other signals commonly sensed in sleep analysis, stores the raw data for later retrieval, extracts features from the digitized signal data which are of a type apt to be significant in classifying and detecting physiological functions (such as the state of sleep) and matches the extracted features to patterns which indicate the type of feature that has been extracted. The matched features are then utilized to classify for each epoch (limited period of time) the state of the physiological function (such as the stage of sleep) for that epoch. The results of the classification analysis are displayed on a CRT screen to the operator on a real time basis and in time correlation with representations of detected features from the various physiological signals.

  • Patent number: 5299117
    Abstract: An information display system is provided having a transmitter and a plurality of uniquely identified display terminals, each terminal having an IR receiver. Uniquely identified sets of messages are transmitted in by the IR transceiver for reception by the display terminals. Between each set of transmissions, the receiver is periodically activated. Once the presence of a transmission is sensed by the receiver, a timer forces the receiver to remain activated while it compares the uniquely identified received messages to the display terminals unique identification. The receiver stores the message that matches the identification of the display terminal and the timer forces the receiver to remain deactivated at least until the entire set of transmissions has been completed.

  • Patent number: 5265011
    Abstract: The system measures the pressure pulses in an upper body peripheral artery and produces an electrical signal which represents the contours of these pulses. It then digitizes the signal and synthesizes the pressure pulses in the ascending aorta using either a frequency-domain or a time-domain calculation method. Next, the system separately averages the signals corresponding to the measured pulses and those corresponding to the synthesized pulses, and forms for each an "average pulse." The system identifies the wave foot in each of the average pulses, identifies the incisura in the average peripheral pulse, determines the amount of time associated with systole and, based on this time, segments the synthesized pulse into systolic and diastolic components.

  • Patent number: 5257183
    Abstract: Method and apparatus for converting x-ray cone beam data (line integrals through an object) to Radon data (planar integrals) for 3D CT image reconstruction by inverse Radon transformation. The radial derivative of each planar integral is determined by integrating to determine weighted line integrals along each of a pair of lines on a normalized detector plane, which lines are defined as intersections with the normalized detector plane of a corresponding pair of integration planes sharing a rotation axis and rotated with respect to each other by a rotation angle .delta..beta., and then dividing the difference between the weighted line integrals by the rotation angle .delta..beta.. The procedure can be employed to convert the cone beam data to values representing planar integrals on any arbitrary set of planes in Radon space, such as a set of coaxial vertical planes.

  • Patent number: 5243521
    Abstract: The present invention is directed to utilizing data indicative of formation resistivity and calculating the width and depth of a fracture therefrom. In the preferred embodiment, the present invention employs data acquired from a formation microscanner tool. Potential fracture locations are detected for acquired formation microscanner tool data preferably by taking into account the relatively slowly varying conductivity changes in the rock matrix, and separating them out from the high and narrow peaks generated by fractures. Each potential fracture location can be depicted as current from the formation microscanner tool versus azimuth, wherein the current measured by the formation microscanner tool is essentially flat for the formation but peaked for potential fracture locations.
