Patent number: 12242693Abstract: The present application provides a display device, a driving method thereof, and an active stylus thereof. The display device uses a second time section to transmit display data, uses a first time section and a third time section to transmit uplink signals with a lower anti-interference ability, and simultaneously adjusts a data transmission sequence of the active stylus and uses the third time section to transmit first touch data with a lower anti-interference ability to prevent interference of the display noise with the data of the active stylus and improve a recognition rate of touch data of the active stylus.Type: GrantFiled: June 7, 2022Date of Patent: March 4, 2025Assignee: Wuhan China Star Optoelectronics Semiconductor Display Technology Co., Ltd.Inventors: Yitong Liu, Houfu Gong, Zengjian Jin

Patent number: 12120627Abstract: In a data processing method for node localization in wireless sensor networks, a plurality of potential coordinate calculation values for a to-be-located node are calculated based on RSSI data received by the to-be-located node from a plurality of anchor nodes. A centroid C1 of these coordinate calculation values is calculated. Then coordinate calculation values with distances to the centroid C1 less than a threshold are screened out, and a centroid C2 of the screened-out coordinate calculation values is calculated. A coordinate position of the centroid C2 is used as the position of the to-be-located node. In other words, a plurality of potential positions for the to-be-located node are calculated using multiple groups of RSSI data and these potential positions are then screened through calculation. Instead of directly processing the received RSSI data, the present disclosure processes the coordinate calculation values obtained based on the received RSSI data.Type: GrantFiled: December 6, 2023Date of Patent: October 15, 2024Assignee: Sun Yat-sen UniversityInventors: Yitong Liu, Hao Lin, Xingcheng Liu, Qiang Tu, Yi Xie

Patent number: 12086369Abstract: The present application provides a touch display panel. A shortest distance on a display plane from any point on outer contours of any two of sub-pixel units to a corresponding grid unit of a mesh electrode is very close or even equal. Therefore, brightness displayed by sub-pixels is more uniform at side viewing angles. Especially, brightness displayed by the sub-pixels of different colors at the side viewing angles is more uniform. Accordingly, the present application can solve a problem that the display panel has a large color shift at the side viewing angles.Type: GrantFiled: July 1, 2022Date of Patent: September 10, 2024Assignee: WUHAN CHINA STAR OPTOELECTRONICS SEMICONDUCTOR DISPLAY TECHNOLOGY CO., LTD.Inventors: Yitong Liu, Zhuo Zhang, Zengjian Jin

Publication number: 20180070755Abstract: A juicer comprises a frame, an actuator, and a juicing bag. The actuator comprises a propulsion plate, stationary parts, moving parts, a driving rod, action blocks and a driver. The frame includes a mounting plate and a front fixed plate facing the mounting plate. The actuator is attached on the mounting plate and the propulsion plate is attached on the actuator and distant from the mounting plate. The juicing bag encloses food and can be placed between the actuator and the fixed surface. The propulsion plate reciprocates linearly between the mounting plate and the front fixed plate to squeeze the food in the juicing bag, thereby juicing with small noise. Because food is enclosed in the juicing bag during juicing, juice does not sputter onto the juicer. Thus, the juicer does not require cleaning.Type: ApplicationFiled: July 21, 2017Publication date: March 15, 2018Inventors: Xiuxing Chen, Yitong Liu, Zechen Yang
