Publication number: 20230405084Abstract: The use of phosphatidylserine as a target for treating inflammatory bowel disease. Phosphatidylserine can be used as a marker of inflammatory bowel disease and used for drug screening. Annexin A5 can be traced by phosphatidylserine in the extracellular membrane and indicate the location of lesions and extent of inflammatory bowel disease, and can be used to treat inflammatory bowel disease.

Patent number: 10375399Abstract: Techniques and systems are provided for generating a background picture. The background picture can be used for coding one or more pictures. For example, a method of generating a background picture includes generating a long-term background model for one or more pixels of a background picture. The long-term background model includes a statistical model for detecting long-term motion of the one or more pixels in a sequence of pictures. The method further includes generating a short-term background model for the one or more pixels of the background picture. The short-term background model detects short-term motion of the one or more pixels between two or more pictures. The method further includes determining a value for the one or more pixels of the background picture using the long-term background model and the short-term background model.Type: GrantFiled: April 20, 2016Date of Patent: August 6, 2019Assignee: QUALCOMM IncorporatedInventors: Lei Wang, Ying Chen, Ning Bi, Xuerui Zhang, Lei Ma, Chinchuan Chiu, Jianfeng Ren

Patent number: 9578299Abstract: The example techniques of this disclosure are directed to generating a stereoscopic view from an application designed to generate a mono view. For example, the techniques may modify source code of a vertex shader to cause the modified vertex shader, when executed, to generate graphics content for the images of the stereoscopic view. As another example, the techniques may modify a command that defines a viewport for the mono view to commands that define the viewports for the images of the stereoscopic view.Type: GrantFiled: January 13, 2012Date of Patent: February 21, 2017Assignee: QUALCOMM IncorporatedInventors: Ning Bi, Xuerui Zhang, Jian Wei

Patent number: 9323988Abstract: Embodiments include methods and systems for context-adaptive pixel processing based, in part, on a respective weighting-value for each pixel or a group of pixels. The weighting-values provide an indication as to which pixels are more pertinent to pixel processing computations. Computational resources and effort can be focused on pixels with higher weights, which are generally more pertinent for certain pixel processing determinations.Type: GrantFiled: July 29, 2014Date of Patent: April 26, 2016Assignee: QUALCOMM IncorporatedInventors: Yingyong Qi, Ning Bi, Xuerui Zhang

Patent number: 9219902Abstract: This disclosure describes techniques for modifying application program interface (API) calls in a manner that can cause a device to render native three dimensional (3D) graphics content in stereoscopic 3D. The techniques of this disclosure can be implemented in a manner where API calls themselves are modified, but the API itself and the GPU hardware are not modified. The techniques of the present disclosure include using the same viewing frustum defined by the original content to generate a left-eye image and a right-eye image and shifting the viewport offset of the left-eye image and the right-eye image.Type: GrantFiled: March 12, 2012Date of Patent: December 22, 2015Assignee: QUALCOMM IncorporatedInventors: Ning Bi, Xuerui Zhang, Jaimin Rohitkumar Bhise, Jianfeng Ren, Manish Madhukar Sirdeshmukh, Qing Zhou

Patent number: 9135503Abstract: In general, this disclosure describes techniques for providing a gesture-based user interface. For example, according to some aspects of the disclosure, a user interface generally includes a camera and a computing device that identifies and tracks the motion of one or more fingertips of a user. In some examples, the user interface is configured to identify predefined gestures (e.g., patterns of motion) associated with certain motions of the user's fingertips. In another example, the user interface is configured to identify hand postures (e.g., patterns of showing up of fingertips). Accordingly, the user can interact with the computing device by performing the gestures.Type: GrantFiled: April 7, 2011Date of Patent: September 15, 2015Assignee: QUALCOMM IncorporatedInventors: Sairam Sundaresan, Ning Bi, Milivoje Aleksic, Yingyong Qi, Xuerui Zhang

Patent number: 9049423Abstract: The techniques of this disclosure are directed to the feedback-based stereoscopic display of three-dimensional images, such as may be used for video telephony (VT) and human-machine interface (HMI) application. According to one example, a region of interest (ROI) of stereoscopically captured images may be automatically determined based on determining disparity for at least one pixel of the captured images are described herein. According to another example, a zero disparity plane (ZDP) for the presentation of a 3D representation of stereoscopically captured images may be determined based on an identified ROI. According to this example, the ROI may be automatically identified, or identified based on receipt of user input identifying the ROI.Type: GrantFiled: December 1, 2010Date of Patent: June 2, 2015Assignee: QUALCOMM INCORPORATEDInventors: Ning Bi, Xuerui Zhang, Yingyong Qi, Chienchung Chang
