Patent Number Title Of Patent Date Issued
6687657 Self-referential method and apparatus for creating stimulus representations that are invariant u February 3, 2004
The inventive method and apparatus include sensory devices that invariantly represent stimuli in the presence of processes that cause systematic sensor state transformations. Such processes include: 1) alterations of the device's detector, 2) changes in the observational environment
6567567 Sampling and reconstruction of RF signals May 20, 2003
A method and apparatus are provided for transceiving a signal. The method includes the steps of transmitting a superposed frequency component of the signal within each of a plurality of non-adjacent frequency bands, using analogue or digital filters within a receiver to suppress all sign
6093153 Method and apparatus for measurement, analysis, characterization, emulation, and translation of July 25, 2000
A method for measuring perception of an observer comprises a) selecting a first, second, and third stimulus and presenting the stimuli to the observer; b) determining observer-defined fourth stimulus such that the observer perceives the fourth stimulus to be related to the third stimulus
6018600 Sampling and reconstruction of signals and images including MR images of multiple regions January 25, 2000
A method and apparatus are provided for acquiring and reconstructing an image. The method includes the steps of obtaining prior knowledge of the image, possibly by coarse sampling of the image and using the obtained prior knowledge of the image to identify relative locations of structure
5860936 Method and apparatus for measurement, analysis, characterization, emulation, and translation of January 19, 1999
A method is used for measuring perception of an observer using a stimulus output device for presenting stimuli to the observer, and a stimulus manipulation device permitting the observer to modify the presented stimuli by selecting related stimuli from a database of stimuli. The meth
5768413 Method and apparatus for segmenting images using stochastically deformable contours June 16, 1998
A method for segmenting an image in which an arbitrarily shaped contour is deformed stochastically until it approximates the contour of a target object. The evolution of the contour is controlled by a simulated annealing process which causes the contour to settle into a global minimum
5546472 Feature guided method and apparatus for obtaining an image of an object August 13, 1996
A method and apparatus for obtaining an image from an object by acquiring training signal measurements which represent images of a plurality of training objects having at least one predetermined feature in common with the object and derive, from the training signal measurements, a set of
5390258 Feature guided method and apparatus for obtaining an image of an object February 14, 1995
A method and apparatus for obtaining an image from an object acquire training signal measurements which represent images of a plurality of training objects having at least one predetermined feature in common with the object and derive, from the training signal measurements, a set of
5081992 Method for calculating localized magnetic resonance spectra from a small number of spatially-enc January 21, 1992
An MR imaging study precedes an MR spectroscopic study. Structural information from the imaging study is combined with MR spectra from the spectroscopic study to produce localized MR spectra.
