Gregory P. Kwok - Berkeley CA, US
Assignee:
nVidia Corporation - Santa Clara CA
International Classification:
G09G 5/00
US Classification:
345 11, 410 8
Abstract:
A method and system using a compressed display mode list is disclosed. In particular, the compressed display mode list includes a plurality of data representing the display modes. The data is formatted according to a plurality of compression format rules. The compression format rules reduce and minimize the size of the compressed display mode list. A driver controls a graphical processing unit that renders an image for displaying on a display device according to a selected display mode from the compressed display mode list. Moreover, a computer-readable medium can store the compressed display mode list.

US Patent:
20210141065, May 13, 2021
Filed:
Jan 6, 2021
Appl. No.:
17/142616
Inventors:
- San Jose CA, US
Mark A. McCord - Los Gatos CA, US
Roger David Cullumber - Hollister CA, US
Yupeng Cui - San Jose CA, US
Dongyi Liao - Mountain View CA, US
Assignee:
Cepton Technologies, Inc - San Jose CA
International Classification:
G01S 7/481
G01S 17/42
G01S 17/89
Abstract:
A method of three-dimensional imaging includes scanning a LiDAR system in a first direction with a first frequency and in a second direction with a second frequency that is different from the first frequency, so that a laser beam emitted by each laser source of the LiDAR system follows a Lissajous pattern. The method further includes emitting, using each laser source, a plurality of laser pulses as the LiDAR system is scanned in the first direction and the second direction; detecting, using each detector of the LiDAR system, a portion of each laser pulse of the plurality of laser pulses reflected off of one or more objects; determining, using a processor, a time of flight for each respective laser pulse from emission to detection; and acquiring a point cloud of the one or more objects based on the times of flight of the plurality of laser pulses.
