Patent number: 11683204Abstract: This application is directed to transferring data over a data link coupled between two electronic devices. The data link includes a retimer having a full data path and a bit level data path that are coupled in parallel. The data link is initiated with the full data path and a first sequence of data packets is transferred via the full data path in accordance with a low data rate setting. While transferring the first sequence of data packets, the first sequence of data packets is manipulated in the full data path to establish a connection of the data link, and in response to establishing the connection of the data link, the data link is switched from the full data path to the bit level data path.Type: GrantFiled: May 26, 2021Date of Patent: June 20, 2023Assignee: PARADE TECHNOLOGIES, LTD.Inventors: Xiang Chen, Wilbur Tsai, Jian Chen, Ming Qu

Patent number: 11501371Abstract: This invention provides a distributed energy transaction matching method based on energy network constraints and multiple knapsack model. First, it considers the matching between financial market transactions and actual energy network scheduling, then generates security constraints on the results of distributed transactions. Next, it designs a multiple knapsack model for peer-to-peer distributed transactions, which can meet the common quotation needs of users or producers who issue transactions and achieve efficient matching under energy network security checks. Finally, the model is verified based on the blockchain Ethereum smart contract test verification. This method provides new ideas for the connection between distributed energy trading and actual physical dispatch, proposes an inclusive and efficient matching model for the point-to-point distributed trading market, which has great reference value for the connection between distributed energy trading and actual conditions.Type: GrantFiled: November 17, 2020Date of Patent: November 15, 2022Assignee: XI'AN JI'AOTONG UNIVERSITYInventors: Tao Ding, Jiangbin Dong, Chenggang Mu, Ming Qu, Ke'er Ning, Xiaobo Dong, Jie Qi, Xiaomeng Zhang, Yuankang He, Tian'en Chen, Yongqing Wang, Jian Liu

Patent number: 11421914Abstract: Methods and apparatus are disclosed for high-efficiency thermal storage with a fluid-filled “battery” tank positioned within a fluid-filled “reservoir” tank. Fluid loops couple the tanks to a heat pump and a building. The heat pump can charge the battery tank or deliver thermal energy (cold or heat) to a building, using the reservoir tank or ambient air as a thermal energy source. The battery tank can discharge energy to the building jointly with the heat pump or, at periods of peak electricity usage, with the heat pump switched off. Operating modes allow significant savings in electricity usage and mitigate the “duck curve.” Low duty cycle usage of the reservoir enables efficient underground thermal storage with less digging than conventional geothermal technologies. Additional efficiency is achieved with phase change materials installed inside a tank or in a tank wall, providing temperature regulation. Control methods are disclosed.Type: GrantFiled: March 13, 2020Date of Patent: August 23, 2022Inventors: Xiaobing Liu, Ming Qu, Joseph K. Warner, Liang Shi

Patent number: 11159353Abstract: This application is directed to transferring data over a data link coupled between two electronic devices. The data link includes a retimer having a full data path and a bit level data path that are coupled in parallel. A first sequence of data packets is transferred via the bit level data path of the retimer. While transferring the first sequence of data packets, the data link detects initiation of an equalization procedure based on an initiation data packet in the first sequence of data packets. In accordance with detection of the initiation of the equalization procedure, the data link selects the full data path of the retimer for data transfer over the data link. During the equalization procedure, a second sequence of data packets immediately follows the first sequence of data packets, and is transferred via the full data path of the retimer.Type: GrantFiled: March 3, 2021Date of Patent: October 26, 2021Assignee: PARADE TECHNOLOGIES, LTD.Inventors: Xiang Chen, Ming Qu, Chi-hsiang Chin, Haijun Zhu

Patent number: 10540314Abstract: A protocol transparent retimer circuit monitors certain link layer control signals, detects far-end receiver parameters of the link partners, and detects attributes of the data signal on the link to determine the link status and operate the retimer in accordance with the determined link status. By combining and reducing host and device system states into a few retimer states, the retimer circuit is largely simplified and yet still serves its purpose. The retimer includes a controller that employs a state machine to interpret the monitored and detected signals to determine the link state and operate the retimer in an operational state corresponding to the determined link state. The approach enables the retimer to restore signal integrity and forward data it receives in both downstream and upstream directions of the link without frequency alteration.Type: GrantFiled: February 1, 2019Date of Patent: January 21, 2020Assignee: PARADE TECHNOLOGIES, LTD.Inventors: Jian Chen, Ming Qu, KC Lee, Zhengyu Yuan, Qing Ouyang

Patent number: 10503683Abstract: A service redirect operation mode allows a tester device to perform software burn-in, firmware upgrade, and other related device interrogation via a USB Type-C connection. The service redirect operation mode is implemented by modifying a termination state of the configuration channel pins of the USB Type-C receptacle of the device under test. Software and/or hardware executing on the device under test re-configure the resistive arrangement of the configuration channel pins, causing one pin to be connected to a reference voltage via a pull-up resistor and the other pin to be connected to ground via a pull-down resistor. When operating in the service redirect operating mode, two additional signal lines of the USB Type-C receptacles may be used to exchange information between the tester and the device under test using a user-specified interface protocol.Type: GrantFiled: November 20, 2015Date of Patent: December 10, 2019Assignee: PARADE TECHNOLOGIES, LTD.Inventors: Jian Chen, Ming Qu, Baoquan Xu, Hongquan Wang
