Patent number: 12113428Abstract: A regulator circuit is presented. The regulation circuit (530) has a regulation switch (131), a voltage comparator (537) with predetermined offset voltage and an adjuster. The regulation switch (131) has a first terminal coupled to a current source (132), a second terminal connectable to a load (110), and a control terminal. The voltage comparator (537) compares a sum voltage of the offset voltage added to a voltage at the second terminal with a control voltage at the control terminal, and generates a comparison signal. The adjuster adjusts the voltage at the second terminal based on the comparison signal to control a difference voltage between the control terminal and the second terminal of the regulation switch and to maintain the regulation switch operating in a desired region of operation.Type: GrantFiled: December 6, 2022Date of Patent: October 8, 2024Assignee: Renesas Design (UK) LimitedInventors: Youzhong Liu, Yanzhao Wang, Yanjun Li, Yixuan Ma

Patent number: 10521415Abstract: Systems and methods are disclosed for providing weighted evaluation. The system may comprise one or more processors and a memory storing instructions that, when executed by the one or more processors, cause the system to obtain a plurality of data point groups, obtain an inbound rank of each data point group based on one or more inbound ranks of one or more data groups linking to the data point group, obtain an outbound rank of the each data point group based on one or more outbound ranks of one or more data groups linked from the each data point group, obtain a group rank of the each data point group based on the inbound rank and the outbound rank of the each data point group, and process the data point groups according to the corresponding group ranks.Type: GrantFiled: May 8, 2017Date of Patent: December 31, 2019Assignee: Facebook, Inc.Inventors: Youzhong Liu, Yunkai Zhou, Jian Huang, Yue Kwen Justin Yip

Publication number: 20190005528Abstract: Methods and systems that allow users to receive automatic discount redemptions without the use of paper coupons or loyalty cards and real time notification of such redemptions. An offer redemption module submits merchant's point of sale registration information and user's financial card account registration information to the card network partner. The card network partner notifies the offer redemption module when a request to authorize a mutual merchant/user transaction is received. The offer redemption module matches the purchase transaction with saved auto-redeemable offers and notifies the acquirer requesting redemption and sends real time notification of redemption to user when there is a match.Type: ApplicationFiled: September 7, 2018Publication date: January 3, 2019Inventors: Marc FREED-FINNEGAN, Youzhong LIU, Prithviraj SUBBURAJ, Stephanie Schear TILENIUS

Patent number: 8291047Abstract: An interface can serve as a client-mainframe interface, enabling clients to develop applications without a need to understand mainframe processes and screen flows. Extended Tool Command Language (Tcl) can define services that can include a series of interactions with a mainframe system and service definitions can be added or updated on the interface during operation of the interface without disrupting processing. The service definitions can enable the interface to receive XML requests from a client, parse the XML requests, execute the service scripts to interact with the mainframe systems, generate the result in a XML format and send the XML file back to the client. Fundamental Mainframe Interactions (FMI) commands can interact with the mainframe systems and enable the specification of the XML structure of the request and response. The interface can provide efficient connection pooling management and connection life cycle control to improve the performance of the mainframe system interactions.Type: GrantFiled: December 7, 2009Date of Patent: October 16, 2012Assignee: Verizon Data Services LLCInventors: Youzhong Liu, Tao Pan, Kaushhik Pillalamarri, Khaldoun Sabagh, Fariborz Ebrahimi
