Patent number: 10760919Abstract: For evaluating navigation information based on line-of-sight measurements, a method measures a line-of-sight measurement with an imager. The method further calculates an information metric based on the line-of-sight measurement. The information metric is a function of imager pixel measurement noise and a relative position vector for an imager frame aligned with a focal plane frame for the imager. The method evaluates navigation information using the information metric.Type: GrantFiled: November 13, 2019Date of Patent: September 1, 2020Assignee: Utah State University Research FoundationInventor: Ryan Lamoreaux

Patent number: 10754242Abstract: Techniques are described for implementing format configurations for multi-directional video and for switching between them. Source images may be assigned to formats that may change during a coding session. When a change occurs between formats, video coders and decoder may transform decoded reference frames from the first format to the second format. Thereafter, new frames in the second configuration may be coded or decoded predictively using transformed reference frame(s) as source(s) of prediction. In this manner, video coders and decoders may use intra-coding techniques and achieve high efficiency in coding.Type: GrantFiled: June 30, 2017Date of Patent: August 25, 2020Assignee: Apple Inc.Inventors: Jae Hoon Kim, Ming Chen, Xiaosong Zhou, Hsi-Jung Wu, Dazhong Zhang, Hang Yuan, Jiefu Zhai, Chris Y.

Patent number: 10638111Abstract: An imaging system with a light source controls the sensitivity of pixels to light, by performing both superpixel modulation and curtain modulation. The superpixel modulation may facilitate rapid data acquisition. The curtain modulation may suppress the effect of ambient light. In superpixel modulation, each pixel set may be modulated by a separate superpixel modulation signal that causes sensitivity of the pixel set to light to vary over time, and each superpixel may include a pixel from each pixel set. The curtain modulation may cause pixels in only a small region of the photodetector to be sensitive to light. The curtain modulation may cause the small region to move to track the dot of light, by changing which pixels are in the region. This invention may be used for 3D scanning.Type: GrantFiled: November 14, 2018Date of Patent: April 28, 2020Inventors: Tomas Kovacovsky, Jan Zizka, Michal Maly

Patent number: 10623665Abstract: Systems and apparatus may include converter device(s), a matrix switch, processor(s), and memory(s), where one or more of the converter devices provide video input signals to the matrix switch. A processor may determine if one of a plurality of video signals input to the matrix switch includes data representative of identification information overlain on a video image derived from one of the plurality of video signals. The determination may be based on a flag value stored in the converter device(s). The flag value may be retrieved by a server coupled to the matrix switch. If the information is included in the video signal, the video signal may be passed through a path in a matrix switch configured by the processor. If the information is not included in the video signal, the data representative of identification information may be retrieved from the converter device and then overlain on the video image.Type: GrantFiled: September 19, 2016Date of Patent: April 14, 2020Assignee: BLACK DIAMOND VIDEO, INC.Inventor: Edward Priest
