Title: Interactive graphical method for analyzing many-dimensional data sets
Inventor: RABENHORST DAVID A
IPC: G01D7/00
Filed: 1992-11-13
Abstract: The present invention is a method and apparatus for analyzing, selecting, manipulating, displaying, and exploring relationships among variables in data bases with a large number of variables. The invention comprises an array of pictorial presentations, usually scatter plots. Each scatter plot shows the relationship among some subset of variables in the database. The scatter plots are mutual coupled to one another so that any mathematical transformation of an independent variable in one plot causes changes in other plots with dependent variables according to the relationship between the changed independent variable and the dependent variable. The mutual coupling also applies to color selection and performing logical operations with color on the plots. The plots can access other subsidiary presentations by using specified access criteria. Subsidiary presentations also can access other presentations. All presentations are mutually coupled.

Title: Measurement of fiber diameters and detection of defects
Inventor: BUTTON LESLIE J
IPC: G01B11/08
Filed: 1992-11-27
Abstract: ABSTRACT OF THE DISCLOSURE       Methods  for  measuring  the  diameters  of  transparent filaments with high precision are provided. The methods involve determining the average spatial frequency of the far-field  interference  pattern  produced  by  illuminating  the filament with a beam of laser light using discrete sequence Fourier transforms (DSFTs).  Methods are also provided for making the  diameter measurement  insensitive  to  filament ellipticity by determining the diameter at two locations which are spaced apart by an amount such that a plot of diameter versus angle of rotation for an elliptical filament calculated at the first location is approximately 90° out of phase from the same plot calculated at the second location.  Methods for detecting defects in filaments are also provided in which a characteristic peak in the spatial frequency spectrum of the interference pattern which subdivides into two peaks which migrate in opposite directions as the defect grows in size is detected.

Title: Automated gas delivery system for blood gas exchange devices
Inventor: BERRY GAYLORD L
IPC: A61M1/16
Filed: 1991-06-27
Abstract: A system for delivering oxygen to a gas permeable membrane oxygenator is disclosed. The system may include an integral source of gas (10) under pressure and a source of vacuum (12). A first mass flow controller (106) is connected to the source of gas (10) upsteam in the gas flow from the gas exchange device (14). A pressure valve (112) is positioned in the gas flow between the first mass flow controller (106) and the gas exchange device (14). An atmospheric vent (110) is positioned between the pressure valve (112) and the first mass flow controller (106). A second mass flow controller (128) is positioned downstream from the gas exchange device (14) and is connected to the source of vacuum (12). A central controller (130) commands the pressure valve (112) to maintain the pressure at the inlet of the gas exchange device (14) at a subatmospheric pressure. The second mass flow controller (128) is commanded to maintain a rate of flow which is desired through the gas exchange device (14). The first mass flow controller (106) is commanded to maintain a rate of flow higher than the second mass flow controller (128) to ensure that a sufficient flow of gas is available through the pressure valve (112) and the gas exchange device (14). The excess gas is exhausted through the vent (110). The present invention ensures sufficient gas flow at the gas exchange device (14) to provide transfer of gases with the blood. Also, the pressure of the gas within the gas exchange device (14) is low enough that outgassing through bubbles into the blood is avoided.

Title: Electronic high-fidelity screenless conversion system and method using a separable filter
Inventor: XIE ZHENHUA
IPC: G03F5/00
Filed: 1993-01-04
Abstract: ABSTRACT OF THE DISCLOSURE                 ELECTRONIC HIGH-FIDELITY SCREENLESS CONVERSION SYSTEM AND METHOD USING A SEPARABLE FILTER           A system for converting a continuous tone value to an output value having either a first level or a second level develops a first error based upon the application of a separable filter to an output value having a first level assumed  for  the  continuous   tone  value  undergoing conversion.   A second error is developed based upon the application of the separable filter to an output value having a second level assumed for the continuous tone value undergoing conversion.  If the first error is greater than the second error, the continuous tone value is converted to the output value having the second level.  Otherwise, the continuous tone value is converted to the output value having the first level.  The resulting error is diffused in a  predetermined  manner  to  neighboring  continuous  tone values yet to be converted.

Title: Video image processing
Inventor: THOMAS GRAHAM ALEXANDER
IPC: H04N5/93
Filed: 1991-09-20
Abstract: The appropriate one of a list of possible motion vectors is applied to each region of a video image. An image value for that region is determined for each of four successive fields, for each of the possible motion vectors. The values for the four fields are compared and when the values are substantially the same for a given vector it is assumed that that is the vector apppropriate to that region. The vectors appropriate to regions of obscured or revealed background can also be assigned by comparing inter-field differences and determining regions where the inter-field differences are high for the central pair and one outer pair and low for the other outer pair of fields. To generate regions corresponding to obscured background only information from the earlier fields is used and to generate regions corresponding to revealed background only information from the later fields is used.

Patent CA-2094833-A1 (CA)
Inventor: BLOOMFIELD BRYAN A
IPC: G05D1/02
Filed: 1991-10-07
Abstract: An improved accuracy position and direction updating system for use with an automatic guided vehicle that navigates by dead reckoning.  Permanent magnets providing detectable position indicators are mounted in the floor and may be at widely spaced locations such as fifty feet apart along the route of the vehicle. A row of Hall sensors is transversely mounted on the vehicle. The sensors detect the lateral location of each floor magnet relative to the vehicle as the vehicle passes over the magnet. Sensors are precalibrated, correcting for errors in sensor null voltage readings due to changes in sensor characteristics due to causes comprising aging and temperature. Data from five sensors that are closest to the magnet are correlated with a stored pattern of magnetic field and their position data are averaged to determine a first estimate of the lateral or first dimensional position of the vehicle, A running average is calculated from sequentially acquired estimates to improve the results. Such precalibration and averaging provides an improved accuracy of the lateral or first dimensional position measurement between the array of Hall sensors and the magnet. A high frequency measurement of the time at which the signals from the row of sensors reaches a peak value, which is the time that the row of sensors arrives at the magnet, provides an improved second dimensional position measurement. More than one magnet is read concurrently to provide position and bearing information during one processing cycle.

Filed: 1992-01-29
Abstract: In the field of monoclonal antibody production, the invention relates to the production of F(ab')2 and Fab' fragments from immunoglobulins. The fragments are produced by acidifying a hybridoma conditioned culture medium containing immunoglobulins with citric acid to a pH of about 3.5 and incubating the conditioned medium at 25 ·C. A proteolytic enzyme in the conditioned medium cleaves the immunoglobulins to F(ab')2 fragments, which may then be treated with a reducing agent to generate Fab' fragments.
