Assignee:
NVIDIA Corporation - Santa Clara CA
International Classification:
G06F 15/80
G06F 15/00
G06T 1/00
US Classification:
345505, 345501
Abstract:
A system, method, and computer program product are provided for generating a ray tracing data structure utilizing a parallel processor architecture. In operation, a global set of data is received. Additionally, a data structure is generated utilizing a parallel processor architecture including a plurality of processors. Such data structure is adapted for use in performing ray tracing utilizing the parallel processor architecture, and is generated by allocating the global set of data among the processors such that results of processing of at least one of the processors is processed by another one of the processors.

Fabrication Of Fiber Supported Ionic Liquids And Methods Of Use

View page
US Patent:
8383026, Feb 26, 2013
Filed:
Oct 21, 2010
Appl. No.:
12/909180
Inventors:
David R. Luebke - Bethel Park PA, US
Shan Wickramanayake - Pittsburgh PA, US
Assignee:
U.S Department of Energy - Washington DC
International Classification:
D01D 5/06
B01D 53/04
B01D 53/22
US Classification:
264178R, 26417216, 264178 F, 264203, 95 45, 95 51, 95 90, 95139
Abstract:
One or more embodiments relates to the production of a fabricated fiber having an asymmetric polymer network and having an immobilized liquid such as an ionic liquid within the pores of the polymer network. The process produces the fabricated fiber in a dry-wet spinning process using a homogenous dope solution, providing significant advantage over current fabrication methods for liquid-supporting polymers. The fabricated fibers may be effectively utilized for the separation of a chemical species from a mixture based on the selection of the polymer, the liquid, and the solvent utilized in the dope.

US Patent:
20130310569, Nov 21, 2013
Filed:
May 21, 2013
Appl. No.:
13/898843
Inventors:
Hunaid Nulwala - Pittsburgh PA, US
Robert Thompson - Pittsburgh PA, US
David Luebke - Bethel Park PA, US
Erik Albenze - Bethel Park PA, US
International Classification:
C07D 249/06
C07D 249/04
C07F 7/10
US Classification:
548110, 548255
Abstract:
A method of synthesizing an ionic liquid, includes reacting a 1,2,3-triazole including at least one of a 4-substituent or a 5-substituent with a hydroxide compound having the formula ROH in a dehydration reaction, wherein R is an ionic liquid cation.

In a number of embodiments, R is a pyridinium cation, a bipyridinium cation, an amino pyridinium cation, a pyridazinium cation, an ozaxolium cation, a pyrazolium cation, an imidazolium cation, a pyramidinium cation, a triazolium cation, a thiazolium cation, an acridinium cation, a quinolinium cation, an isoquinolinium cation, an orange-acridinium cation, a benzotriazolium cation, a methimzolium cation, a sulfonium cation, an ammonium cation, or a phosphonium cation.

Retina Space Display Stabilization And A Foveated Display For Augmented Reality

View page
US Patent:
20190302883, Oct 3, 2019
Filed:
Mar 27, 2019
Appl. No.:
16/365941
Inventors:
- Santa Clara CA, US
Josef Bo Spjut - Durham NC, US
David Patrick Luebke - Charlottesville VA, US
International Classification:
G06F 3/01
H04N 13/383
H04N 13/332
G06T 1/20
Abstract:
Perceived clarity of an image presented by a display can be improved using an image stabilization technique to stabilize the image relative to a user's retina. During an illumination period, stabilization actuators are controlled to move a display panel or adjust optical components in the path of light associated with the image to shift the location of the image on the user's retina in response to head or eye movement detected by the system. In some embodiments, a display is configured to illuminate an image, and at least one stabilization actuator is configured to stabilize the image in a retina space associated with a user. Changes in the retina space can be detected by one or more sensors configured to detect a head position of the user and/or an orientation of the user's retina. The image is stabilized in retina space using the stabilization actuators.
