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.

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

- 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.

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.

Appl. No.:

15/414525
Inventors:

- Monterey Park CA, US
Wei Qian - Torrance CA, US
Zhi Li - Alhambra CA, US
Jacob Levy - Sierra Madre CA, US
International Classification:

G02F 1/025
H01S 5/024
H01S 5/12
Abstract:

The optical device includes a waveguide positioned on a base and a modulator positioned on the base. The modulator includes an electro-absorption medium. The waveguide is configured to guide a light signal through the modulator such that the light signal is guided through the electro-absorption medium. A heater is positioned on the electro-absorption medium such that the electro-absorption medium is between the base and the heater.
