Publication number: 20240104686Abstract: Techniques are disclosed herein for implementing a novel, low latency, guidance map-free video matting system, e.g., for use in extended reality (XR) platforms. The techniques may be designed to work with low resolution auxiliary inputs (e.g., binary segmentation masks) and to generate alpha mattes (e.g., alpha mattes configured to segment out any object(s) of interest, such as human hands, from a captured image) in near real-time and in a computationally efficient manner. Further, in a domain-specific setting, the system can function on a captured image stream alone, i.e., it would not require any auxiliary inputs, thereby reducing computational costs—without compromising on visual quality and user comfort. Once an alpha matte has been generated, various alpha-aware graphical processing operations may be performed on the captured images according to the generated alpha mattes (e.g.Type: ApplicationFiled: September 19, 2023Publication date: March 28, 2024Inventors: Srinidhi Aravamudhan, Adrian P.

Patent number: 11281272Abstract: In a power supply having a control circuit for regulating the power supply output and a load switch for connecting the output to a load device, a method for reducing standby power includes determining if a load device is connected to the power supply. If no load device is connected, the load switch is turned off, and the power supply enters a standby mode, which includes alternating first time period of power-saving mode and second time period of regulating mode. In the power-saving mode, the control circuit stops regulating the output of the power supply and turns off one or more functional blocks to allow the output to drop, until the output reaches a pre-set low output limit. In the regulating mode, the control circuit turns on the functional blocks and regulates the power supply to allow the output to increase, until the output reaches a pre-set high output limit.Type: GrantFiled: March 4, 2020Date of Patent: March 22, 2022Assignee: DIODES INCORPORATEDInventors: Ko-Yen Lee, Adrian Wang, Clive Huang

Patent number: 10278242Abstract: A power supply includes a power converter configured to convert an input voltage to a target output DC voltage in response to a feedback signal, the feedback signal having a value. The power supply also includes a regulator coupled to the power converter and configured to generate an output power status signal, which maybe in one of two states depending whether an output current from the regulator is above or below a target current over a preset time duration. Further, a control circuit is coupled to the power converter and to the regulator and configured to increment or decrement the value of the feedback signal depending on the state of the power status signal.Type: GrantFiled: July 21, 2017Date of Patent: April 30, 2019Assignee: DIDDES INCORPORATEDInventors: Adrian Wang, Chien-Jen Su

Publication number: 20170303358Abstract: A multiple channel current regulator is configured to deliver a maximum current to a load associated with the channel in a lighting system. Different channels may have a different maximum current and the ratio among the maximum currents is fixed. In operation, the current of each channel can be individually modulated by a pulse stream that controls the current that flows to the load.Type: ApplicationFiled: September 30, 2014Publication date: October 19, 2017Applicant: Diodes IncorporatedInventor: Adrian Wang
