US Patent:

20120054785, Mar 1, 2012
Filed:

Aug 31, 2010
Appl. No.:

12/872393
Inventors:

Paritosh Bajpay - Edison NJ, US
Zhi Li - San Ramon CA, US
David Lu - Morganville NJ, US
Balaji Puli - San Ramon CA, US
Raghvendra Savoor - Walnut Creek CA, US
Anthony Srdar - Dawsonville GA, US
Assignee:

AT&T INTELLECTUAL PROPERTY I, L.P. - Reno NV
International Classification:

H04H 60/32
US Classification:

725 16
Abstract:

A computer-implemented method includes receiving, at a monitoring center of a media distribution network, from a set top box device associated with a customer account, first error data indicating occurrence of a first error at the set top box device at a first time. The set top box device is at least partially functional after occurrence of the first error. The computer-implemented method includes receiving, at the monitoring center, second error data indicating occurrence of a second error at the set top box device at a second time. The set top box device is at least partially functional after occurrence of the second error. The computer-implemented method includes determining an elapsed time between the first time and the second time. The computer-implemented method includes automatically generating a trouble ticket indicating failure of the set top box device when the elapsed time satisfies a first threshold.

US Patent:

20130060529, Mar 7, 2013
Filed:

Sep 1, 2011
Appl. No.:

13/223451
Inventors:

Zhi Li - Cypress CA, US
Jingmei Wang - Shanghai, CN
Assignee:

SIEMENS PRODUCT LIFECYCLE MANAGEMENT SOFTWARE INC. - Plano TX
International Classification:

G06F 17/50
US Classification:

703 1
Abstract:

Methods for computer-aided design and corresponding systems and computer-readable mediums. A method includes receiving a CAD model including a plurality of intersecting fluid channels, and determining a fluid inlet for the fluid channels. The method includes displaying possible fluid flow directions at an intersection of fluid channels. The method includes automatically adding a cooling fitting to at least one of the fluid channels of the CAD model in response to a user selection of one of the possible fluid flow directions.

US Patent:

20210248292, Aug 12, 2021
Filed:

Sep 12, 2018
Appl. No.:

17/268758
Inventors:

Xueqin HE - Shanghai, CN
Sheng-Der TANG - Irvine CA, US
Zhi LI - Cypress CA, US
Chee-Keong CHONG - Irvine CA, US
Jingmei WANG - Shanghai, CN
Yunfei WU - Arcadia CA, US
Lei YANG - Los Alamitos CA, US
- Plano TX, US
International Classification:

G06F 30/23
G06F 30/18
G06T 17/20
Abstract:

A computer-aided design (CAD) system may support detection of internal channel networks for 3D printing and may include a CAD model access engine and a channel network detection engine. The CAD model access engine may access a CAD model of a physical object to be constructed through 3D printing. The channel network detection engine may detect an internal channel network included in the CAD model of the physical object, including by identifying channel openings along a surface of the CAD model that satisfy an opening size threshold and recursively identifying internal faces of the CAD model that form the internal channel network, wherein the internal faces are faces of the CAD model that are internal to the surface of the CAD model. The channel network detection engine may also perform a channel verification on the identified internal channel network to support the 3D printing of the physical object.

Spatially-Aware Detection Of Trapped Support Areas In 3D Printing

US Patent:

20200074016, Mar 5, 2020
Filed:

Sep 4, 2018
Appl. No.:

16/121410
Inventors:

- Plano TX, US
Zhi Li - Cypress CA, US
Lei Yang - Alamitos CA, US
International Classification:

G06F 17/50
B33Y 50/00
B29C 64/386
Abstract:

A computer-aided design (CAD) system may support spatially-aware detection of trapped support areas in 3D printing. The CAD system may detect trapped support areas in the surface mesh in that detected trapped support area do not have linear access to an opening in the surface mesh, including by surrounding the surface mesh with a virtual bounding box that encloses the surface mesh, mapping the virtual bounding box and surface mesh into a 3D cube space, and tracking mesh cubes and bounding cubes of the 3D cube space. For a given mesh face of the surface mesh, The CAD system may determine whether the given mesh face is part of a trapped support area by projecting a ray from the given mesh face and assessing the given mesh face as part of a trapped support area based on the ray passing through a mesh cube or a bounding cube.
