Publication number: 20230313968Abstract: A lens plate has an array of lenslets. A first surface comprises a plurality of individual cells, each cell delimiting one side of a respective lenslet of the array. A second opposite surface comprises a set of grooves, each groove delimiting a second, opposite side, of a sub-array of the lenslets of the array of lenslets. The array of lenslets is a circular array comprising a plurality of concentric rings. Each ring comprises a plurality of straight segments, and each segment comprises multiple said lenslets arranged in a row. The lens plate design thus combines grooves on one side which cover multiple lenslets and a cellular lens structure on the opposite side.Type: ApplicationFiled: July 13, 2021Publication date: October 5, 2023Inventors: Yun LI, Jun LU, Hang LI, Andrew CHRISTANTO, Ximei LIAN, Weihua MIAO, Shengfeng LI, Shelley Sj CAO, Xueqin LIN

Patent number: 10845677Abstract: A flash system for an electronic device includes a ring-shaped light guide having a central opening. A camera lens is positioned in or behind the opening. A first light emitting diode (“LED”) is mounted on a printed circuit board (“PCB”), and the LED and PCB are encapsulated by a molded light guide of the flash system. An identical LED and PCB are encapsulated at an opposite end of the molded light guide (i.e., 180 degrees away). The back surfaces of each PCB diffusively reflects light from the LED on the other PCB. Light extraction features on the light guide surface uniformly leak out light from the LEDs. The light emission profile of the light guide has a peak axially aligned with the central opening of the light guide and rolls off to the edge of the camera's field of view.Type: GrantFiled: December 31, 2019Date of Patent: November 24, 2020Assignee: Lumileds LLCInventor: Xueqin Lin

Patent number: 9674271Abstract: A method for storing information items from a client device to a remote server is performed at the client device having memory and one or more processors, the remote server being communicatively coupled to the client device. The client device renders an information item and an information storing option associated with the information item using a first application at the client device. Upon detecting a user selection of the information storing option, the client device invokes a second application, which may or may not run on the client device, to upload data associated with the information item rendered on the client device to the remote server and then resumes the rendition of the information item using the first application at the client device.Type: GrantFiled: April 28, 2013Date of Patent: June 6, 2017Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Bin Zhang, Xueqin Lin, Zhiyuan Lin, Jiangxun Lin, Zhuo Tang, Ling Li, Yi Dan

Patent number: 9276883Abstract: A mobile terminal collects information items identified by a user of the mobile terminal, the collected information items having different formats of data that are to be rendered by different applications at the mobile terminal. The mobile terminal synchronizes itself with the remote server so that the user can access the plurality of information items stored at the remote server from another terminal. Next, the mobile terminal displays some information items in a chronological order. In response to detecting a user selection of one information item, the mobile terminal determines whether data associated with the information item is in the mobile terminal or not. If the data is present in the mobile terminal, the mobile terminal then renders the data on the mobile terminal. Otherwise, the mobile terminal first downloads the data from the remote server and then renders the data on the mobile terminal.Type: GrantFiled: April 28, 2013Date of Patent: March 1, 2016Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Bin Zhang, Kai Li, Xueqin Lin, Zhiyuan Lin, Jiangxun Lin, Zhuo Tang, Ling Li, Yi Dan

Patent number: 9092532Abstract: When location information and a user Identification (ID) is received from a client terminal device of a user X, a grid Y, to which the location information belongs, is determined. The user ID and the location information of the user X is stored in a list of the grid Y. The grid Y is in a grid array obtained by dividing a surface of the earth into the grids and areas of the grids are the same. Users in the grid Y and other grids are searched. The grid Y and the other grids form an N-grid and the grid Y is a center of the N-grid. The users are ranked in an ascending order of distances between the users and the user X. The ranked user IDs and distances between the users and the user X are sent to the client terminal device of the user X.Type: GrantFiled: May 14, 2014Date of Patent: July 28, 2015Assignee: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Junchao Chen, Zhonghua Lai, Haochuan Cui, Yu Wu, Cuilong Ma, Jingqiong Feng, Tianqing Huang, Wa Ye, Xiangyao Lin, Xueqin Lin, Yuxuan Zhang, Kunfeng Rong, Guo Ling
