Patent number: 11972182Abstract: Provided is a method for a dynamic state estimation of a natural gas network considering dynamic characteristics of natural gas pipelines. The method can obtain a result of the dynamic state estimation of the natural gas network by establishing an objective function of the dynamic state estimation of the natural gas network, a state quantity constraint of a compressor, a state quantity constraint of the natural gas pipeline and a topological constraint of the natural gas network, and using a Lagrange method or an interior point method to solve a state estimation model of the natural gas network. The method takes the topological constraint of the natural gas network into consideration, and employs a pipeline pressure constraint in a frequency domain to implement linearization of the pipeline pressure constraint, thereby obtain a real-time, reliable, consistent and complete dynamic operating state of the natural gas network.Type: GrantFiled: May 18, 2021Date of Patent: April 30, 2024Assignee: TSINGHUA UNIVERSITYInventors: Hongbin Sun, Qinglai Guo, Bin Wang, Guanxiong Yin, Zhaoguang Pan, Binbin Chen

Patent number: 10803663Abstract: A method for depth sensor aided estimation of virtual reality environment boundaries includes generating depth data at a depth sensor of an electronic device based on a local environment proximate the electronic device. A set of initial boundary data is estimated based on the depth data, wherein the set of initial boundary data defines an exterior boundary of a virtual bounded floor plan. The virtual bounded floor plan is generated based at least in part on the set of initial boundary data. Additionally, a relative pose of the electronic device within the virtual bounded floor plan is determined and a collision warning is displayed on a display of the electronic device based on the relative pose.Type: GrantFiled: August 2, 2017Date of Patent: October 13, 2020Assignee: GOOGLE LLCInventors: Zhaoguang Wang, Mugur Marculescu, Chris McKenzie, Ambrus Csaszar, Ivan Dryanovski

Patent number: 10244410Abstract: Power and resource efficiency of a mobile network device are increased. In one aspect, a tail optimization protocol (TOP) enables cooperation between a mobile device and an associated radio access network to eliminate idle periods (e.g., tails) when possible. Various systems and methods described herein can leverage the ability of applications and/or their associated connections to accurately predict a long tail time, from which a mobile device can notify an associated cellular network on such an imminent tail in order to allow the cellular network to immediately release tail resources. Various other aspects provided herein realize TOP via fast dormancy and/or other similar notification mechanisms, which enable a handset or other device to notify a cellular network for immediate resource release.Type: GrantFiled: June 10, 2016Date of Patent: March 26, 2019Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Alexandre Gerber, Zhuoqing Mao, Feng Qian, Subhabrata Sen, Oliver Spatscheck, Zhaoguang Wang

Patent number: 10165576Abstract: Techniques control traffic transmissions to manage radio resource utilization. When content is being streamed to user equipment (UE) and is at least initially intended to be streamed in real time at a constant bitrate, a communication management component can determine whether the content being transmitted to the UE can be delayed, instead of being transmitted in real time. In response to determining that the content can be delayed, the communication management component can facilitate buffering data and periodically streaming the data to the UE in data bursts to reduce use of UE power and radio resources. When transmitting a visual image to a UE, the communication management component can adjust resolution of a visual image to correspond to screen dimensions of the UE based on information indicating screen dimensions of the UE that can be received from the UE.Type: GrantFiled: June 1, 2018Date of Patent: December 25, 2018Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Subhabrata Sen, Oliver Spatscheck, Alexandre Gerber, Zhuoqing Morley Mao, Feng Qian, Zhaoguang Wang
