Publication number: 20230247178Abstract: Embodiments of this application provide a method and apparatus, a terminal and a medium. The method includes the following steps. A target terminal displays, in a video session, a video session interface including an image display region for displaying images associated with one or more users participating in the video session. The target terminal displays a target virtual image of a user of the target terminal in the image display region. The target terminal acquires movement information of the user and controls the target virtual image displayed in the image display region to perform a target interaction action corresponding to the movement information of the user. Finally, the target terminal transmits movement data of the target virtual image performing the target interaction action, to terminals of the other users of the video session to render the target virtual image to perform the target interaction action on the corresponding terminals.Type: ApplicationFiled: April 13, 2023Publication date: August 3, 2023Inventors: Wenjing YIN, Zebiao HUANG, Xianyang XU, Shu-hui CHOU, Zhimiao YU

Patent number: 9496880Abstract: Certain aspects of the present disclosure provide methods and apparatus for implementing a fully differential charge pump circuit that eliminates a source of noise and power consumption by using a low-noise switched-capacitor common-mode feedback (CMFB) circuit, rather than a continuous-time amplifier-based CMFB circuit. The fully differential charge pump circuit presented in this disclosure includes the switched-capacitor CMFB (SC-CMFB) unit connected to differential output nodes of the charge pump and provides a feedback signal to the charge pump to control a common-mode voltage of the differential signals based on a reference common-mode voltage. In certain aspects, a replica phase-frequency detector (PFD), a frequency divider, and a non-overlapping clock generator provides control signals for the SC-CMFB circuit.Type: GrantFiled: August 14, 2015Date of Patent: November 15, 2016Assignee: Qualcomm IncorporatedInventors: Wenjing Yin, Jeffrey Mark Hinrichs

Patent number: 8878614Abstract: A PLL circuit includes an oscillator, a detection block, an integral path and a proportional path. The oscillator generates an oscillation signal. The detection block detects a phase difference between the oscillation signal and a reference signal and generates an integral signal that represents an integral value of the phase difference and a proportional signal that represents a current value of the phase difference. The integral path includes a regulator that receives the integral signal and supplies a regulated integral signal to the oscillator, and the regulator has a feedback loop including an error amplifier. The proportional path supplies the proportional signal, separately from the integral signal, to the oscillator. The oscillator generates the oscillation signal having an oscillation frequency controlled by both of the regulated integral signal and the proportional signal such that the phase of the oscillation signal is locked to the phase of the reference signal.Type: GrantFiled: February 28, 2012Date of Patent: November 4, 2014Assignee: MegaChips CorporationInventors: Wenjing Yin, Anand Gopalan
