Patent number: 11997523Abstract: Various examples pertaining to efficient trigger-based (TB) multi-user (MU) uplink (UL) transmissions in wireless local area networks (WLANs) are described. A stations (STA) receives a trigger frame from an access point (AP), with the trigger frame assigning one or more resource units (RUs) corresponding to one or more subchannels of a plurality of subchannels. The STA then performs a transmission using the assigned one or more RUs responsive to receiving the trigger frame. In an event that at least one subchannel of the plurality of subchannels is detected as being busy, the one or more subchannels may include a subset (e.g., some but not all) of the plurality of subchannels.Type: GrantFiled: October 20, 2021Date of Patent: May 28, 2024Assignee: MediaTek Singapore Pte. Ltd.Inventors: Jianhan Liu, Shengquan Hu, Yongho Seok, Thomas Edward Pare, Jr., Kai Ying Lu

Publication number: 20240172278Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a station (STA). In certain configurations, the STA transmits a request-to-send (RTS) frame in an enhanced long range (ELR) format for obtaining a transmission opportunity (TXOP). The STA receives a first clear-to-send (CTS) frame in the ELR format or a non-ELR format responding to the RTS frame. In response to receiving the first CTS frame, the STA transmits data in the ELR format in the TXOP. In certain configurations, the STA further receives an acknowledgement in the same format as the first CTS frame for responding to the data being transmitted. In certain configurations, prior to transmitting the RTS frame, the STA transmits a CTS-to-Self frame in the non-ELR format.Type: ApplicationFiled: November 15, 2023Publication date: May 23, 2024Inventors: You-Wei Chen, Jianhan Liu, Kai ying Lu, Shuling Feng, Tsung-Hsuan Wu, Thomas Edward Pare, JR.

Patent number: 11917551Abstract: Embodiments of the present invention are drawn to methods and electronic devices capable of performing coordinate spatial reuse for wirelessly transmitting data on a channel in coordination with another wireless AP operating an overlapping BSS using the same wireless channel. The device can perform RSSI measurements and generate Per-RU RSSI reports including the RSSI measurements information for transmission to another wireless AP. The RSSI measurement can be performed by the device based on power levels detected when receiving TB PPDUs transmitted by wireless STAs responsive to trigger frames, for example. Based on the Per-RU RSSI report, a wireless AP can be configured to transmit data to an associated wireless STA without causing significant interference when another AP of the overlapping BSS is also transmitting, and can schedule frames for transmission from associated wireless STAs accordingly.Type: GrantFiled: March 30, 2021Date of Patent: February 27, 2024Assignee: MEDIATEK SINGAPORE PTE. LTD.Inventors: Yongho Seok, Gary A. Anwyl, Jianhan Liu, Kai Ying Lu, James Chih-Shi Yee, Thomas Edward Pare, Jr., James June-Ming Wang

Patent number: 10686377Abstract: There is presented a boost converter and an associated method for starting the boost converter. The boost converter includes an input terminal for receiving an input voltage, an output terminal for providing an output voltage, a low-side power switch and a high-side power switch coupled at a switching node, and a voltage regulator coupled to the high-side power switch. The boost converter is also provided with a controller for operating the boost converter in a start-up phase. In the start-up phase the controller controls the boost converter to generate an intermediate voltage and increase the intermediate voltage to a predetermined value. The intermediate voltage is then provided to the voltage regulator to obtain a drive voltage. The high side power switch is then driven to increase the output voltage linearly up to a start-up voltage.Type: GrantFiled: September 5, 2019Date of Patent: June 16, 2020Assignee: Dialog Semiconductor (UK) LimitedInventors: Edward Lu, Stella Su, Yuan Wen Hsiao, Der-Ju Hung

Patent number: 10404825Abstract: Refresh requests are received by a data source that each request a snapshot of current members of one of a plurality of dynamically changing groups and dynamically changing rules corresponding to such group. Thereafter, the data source queues the received plurality of refresh requests for selective execution or deletion into a new request queue. In addition, real-time execution of refresh jobs are initiated for all of queued refresh requests if a number of refresh requests in both of the new request queue and a waiting requests queue is below a pre-defined threshold. Alternatively, a job framework schedules execution of task jobs for a subset of the queued requests in the new request queue and the waiting requests queue if certain conditions are met.Type: GrantFiled: December 7, 2016Date of Patent: September 3, 2019Assignee: SAP SEInventors: Jia Feng, Edward Lu, Jessica Yang, Zonghan Wu, Ruibin Zhang, Fangling Liu, Xuejian Qiao, Yan Fan

Patent number: 10230735Abstract: Some embodiments provide a program that receives, from an application, a role-based permission (RBP) request specifying an RBP, a first user, and a second user. The RBP specifies a set of actions, a first set of users authorized to perform the set of actions, a second set of users on which the first set of users is authorized to perform the set of actions, and a relationship condition. When the relationship condition specifies a hierarchy-based relationship, the program determines valid users in the second set of users according to a hierarchy of users. When the relationship condition specifies a non-hierarchy-based relationship, the program determines valid users in the second set of users according to a relationship not based on the hierarchy of users. The program determines whether the first user is authorized to perform the set of actions on the second user based on the determined valid users.Type: GrantFiled: December 30, 2015Date of Patent: March 12, 2019Assignee: SUCCESSFACTORS, INC.Inventors: Jia Feng, Yulong Yang, Lu Luo, Jessica Yang, Edward Lu

Patent number: 10187391Abstract: Described herein is a framework for providing and securing data access by external users. In accordance with one aspect of the framework, an external schema is generated to pair with an existing company schema in a database. The company schema may own data stored in the database. One or more access-control views that expose one or more subsets of the data may further be generated. The external schema may be granted access to the one or more access-control views. Synonyms may be created to rename access-control views, so that the synonyms share common names with corresponding database objects accessible via the company schema. External users may then access the data visible to them via the synonyms that are used to alias the access-control views.Type: GrantFiled: May 6, 2016Date of Patent: January 22, 2019Assignee: SAP SEInventors: Yonghong Mao, Zhi Zhang, Neil Jayesh Patel, Edward Lu, Jessica Yang
