Patent number: 11924513Abstract: Disclosed are a display apparatus and a method for displaying a user interface. In response to a preset instruction, the display apparatus acquires local images to generate a local video stream, plays a local video picture, and displays a graphic element for identifying a preset expected position in a floating layer above the local video picture. When the moving target exists in the local video picture and an offset of a target position of the moving target in the local video picture relative to the expected position is greater than a preset threshold value, a prompt control for guiding the moving target to move to the expected position is presented in the floating layer above the local video picture according to the offset of the target position relative to the expected position.Type: GrantFiled: November 18, 2021Date of Patent: March 5, 2024Assignee: JUHAOKAN TECHNOLOGY CO., LTD.Inventors: Guangqiang Wang, Xiaochun Xu, Zhezhe Liu, Xiangsheng Wu, Yuanyuan Li, Yinyang Chen, Yao Xie, Fanwen Zhang

Publication number: 20190216736Abstract: In order to facilitate the approval and commercialization of silicasome drug delivery systems (e.g. irinotecan silicasomes) it is necessary to scale up synthesis of the drug-loaded silicasomes. In this regard, it was discovered that the synthesis protocols used for laboratory synthesis of drug-loaded silicasomes (e.g., 500 mg/batch) do not scale to large scale silicasome production, because the resulting products were too heterogeneous for use as pharmaceuticals. Accordingly, new methods are provided herein that effectively afford the large-scale production of mesoporous silica nanoparticles (MSNPs) and lipid bilayer coated MSNPs (silicasomes).Type: ApplicationFiled: December 28, 2018Publication date: July 18, 2019Inventors: Andre E.
