Alan E Barr - Seal Beach CA, 90740
International Classification:
0604
US Classification:
D 6407, D6450, D6470, D6303, D6314

Real-Time, Interactive Animation Of Deformable Two- And Three-Dimensional Objects

View page
US Patent:
6573897, Jun 3, 2003
Filed:
May 11, 2000
Appl. No.:
09/569352
Inventors:
Mathieu Desbrun - Pasadena CA
Peter Schroeder - Pasadena CA
Mark Meyer - Pasadena CA
Alan H. Barr - Pasadena CA
Assignee:
California Institute of Technology - Pasadena CA
International Classification:
G06T 1600
US Classification:
345473
Abstract:
A method of updating in real-time the locations and velocities of mass points of a two- or three-dimensional object represented by a mass-spring system. A modified implicit Euler integration scheme is employed to determine the updated locations and velocities. In an optional post-integration step, the updated locations are corrected to preserve angular momentum. A processor readable medium and a network server each tangibly embodying the method are also provided. A system comprising a processor in combination with the medium, and a system comprising the server in combination with a client for accessing the server over a computer network, are also provided.

Method Of Deriving Mesh Surface Representation From Volume Representation

View page
US Patent:
6828966, Dec 7, 2004
Filed:
Apr 29, 2002
Appl. No.:
10/136866
Inventors:
Marcel Gavriliu - Pasadena CA
Joel Carranza - Ocean Springs MS
David E. Breen - Arcadia CA
Alan H. Barr - Pasadena CA
Assignee:
California Institute of Technology - Pasadena CA
International Classification:
G06T 1700
US Classification:
345420
Abstract:
A method of extracting a mesh representation of a surface from a volumetric representation of at least a portion of an object is provided. A surface is derived from the volumetric representation. A seed point on the surface is then selected, and a neighborhood of the seed point is grown over at least a portion of the surface. These selection and growing steps are iteratively repeated until the entire surface is substantially completely covered. Seed points are then selectively connected to form polygons which comprise the mesh representation.

Methods For Computing Barycentric Coordinates Generalized To Irregular N-Gons And Applications Of The Same

View page
US Patent:
7061483, Jun 13, 2006
Filed:
Feb 7, 2002
Appl. No.:
10/071268
Inventors:
Mathieu Desbrun - Pasadena CA, US
Alan H. Barr - Pasadena CA, US
Mark Meyer - Pasadena CA, US
Assignee:
California Institute of Technology - Pasadena CA
International Classification:
G06T 15/00
US Classification:
345419, 345427
Abstract:
A method for deriving barycentric coordinates for a point p within an n-sided polygon is provided wherein, for a particular coordinate w, corresponding to the vertex q, the method embodies a formula which depends only on the edge pq, and the two adjacent angles δand γ. Similarly, a method is provided for deriving weights wfor expressing a vertex qin a mesh representation of an object surface in terms of its one-ring neighbors q, ∀jεN(i). For a particular vertex q, and neighbor vertex q, this method embodies a formula which depends only on the edge qq, and the two adjacent angles δand γ. A method of parameterizing a mesh representation of an object surface using the latter formula is also provided. This method begins with the step of computing the weights win D space (in contrast to parameter space) for each of the vertices in the mesh representation. For a vertex i, iε[. . .

Efficient Method Of Identifying Non-Solution Or Non-Optimal Regions Of The Domain Of A Function

View page
US Patent:
7076516, Jul 11, 2006
Filed:
Sep 18, 2001
Appl. No.:
09/956590
Inventors:
Marcel Gavriliu - Pasadena CA, US
Alan H. Barr - Pasadena CA, US
Assignee:
California Institute of Technology - Pasedena CA
International Classification:
G06F 7/38
US Classification:
708446
Abstract:
A method of identifying one or more regions of the domain of a function that do not contain solutions is described along with a related subdivision method. These methods may be employed in the context of branch and bound methods that use interval analysis to search for solutions of functions. The one or more regions of the function domain that do not contain solutions are identified using a cropping formula derived from one or more components (low order and high order) of a Taylor Form inclusion function. A Corner Taylor Form inclusion function is also described which might be used to identify the output range of a function.

Optical Systems For Diagnosing And Monitoring Dermal Microvascular Health

US Patent:
20100241015, Sep 23, 2010
Filed:
Dec 8, 2009
Appl. No.:
12/633579
Inventors:
Danny Petrasek - Los Angeles CA, US
Morteza Gharib - Altadena CA, US
Alan H. Barr - Pasadena CA, US
Eric M. Chin - Memphis TN, US
Assignee:
California Institute of Technology - Pasadena CA
International Classification:
A61B 5/02
G01N 21/55
US Classification:
600504, 356445
Abstract:
The invention generally relates to a device for assessing dynamic microvascular refill (DMR), a novel measure of microvascular function. Microvascular refill is determined under dynamic conditions by monitoring changes in fingernail reflectance spectra in response to small shear forces applied to the fingernail. A hemodynamic model is described to examine the physiological significance of observed signals. The invention will provide healthcare workers with a simple, user friendly, non-invasive method of rapidly assessing microvascular function that would greatly facilitates the early detection and monitoring of the onset and treatment of vascular diseases.

Imaging System For Correction Of Perceptual Distortion In Wide Angle Images

US Patent:
59996609, Dec 7, 1999
Filed:
Jul 26, 1995
Appl. No.:
8/506764
Inventors:
Denis Zorin - Pasadena CA
Alan H. Barr - Pasadena CA
Assignee:
California Institute of Technology - Pasadena CA
International Classification:
G06K 964
US Classification:
382276
Abstract:
An imaging system which corrects perceptual distortion in wide angle picture balances between direct view distortion and linear perspective distortion. The two kinds of distortion are balanced according to a transformation ratio. The balancing can be expressed as: and. phi. =. o slashed. where. rho. and. phi. are the transformed polar coordinates corresponding to the original polar coordinates r and. o slashed. ,. lambda. is the transformation ratio defining the amount of each transform to be used, and R is the size of the new image. This can also be effected by a lens having the transfer characteristic whereby B=tan. beta. /K; where K is between 1 and 2.

Circuit And Method For Estimating Gradients

View page
US Patent:
53294785, Jul 12, 1994
Filed:
Nov 25, 1992
Appl. No.:
7/981762
Inventors:
David B. Kirk - South Pasadena CA
Douglas A. Kerns - Pasadena CA
Brooke P. Anderson - Pasadena CA
Kurt Fleischer - Pasadena CA
Alan H. Barr - Pasadena CA
International Classification:
G06G 718
US Classification:
364828
Abstract:
A circuit and method for estimating gradients of a target function using noise injection and correlation is provided. In one embodiment, an input signal is combined with an input noise signal and the combined signal is input to a circuit which computes the output of the target function. An amplified noise signal and output signal of the target function are input to a multiplier which performs a correlation of the inputs. The output of the multiplier is processed by a low-pass filter which generates the gradient. The circuit and method can be expanded to N-dimensions. Furthermore, in a alternate embodiment, a differentiator is coupled between the multiplier and amplifier and the multiplier and the output of the target function to differentiate the two signals prior to input to the multiplier. In other embodiments, the circuit may be used to compute gradient-like signals, wherein each component of the gradient is individually scaled by a different value. The output of the circuit can then be used in other descent algorithms.
