Publication number: 20240067516Abstract: This vented spout relates to a detachable pouring spouts that can be used to transfer liquid contents from a filling container to a receiving container. More particularly, the present invention relates to a detachable self-venting, non-spilling pouring spout. This vented spout has a side air channel or air channels including one way valves that prevent liquid back out from the air channel and also does not reduce the pouring orifice cross section which would result in accelerating the flow rate of substance. The vented spout has a thread shape portion which will create spinning flow and enhancing flow rate as well. It's also flexible so that the spout can be bend to different directions which helps reduces storage space due to the bending.Type: ApplicationFiled: August 28, 2022Publication date: February 29, 2024Inventor: Xuan Zeng

Patent number: 11438431Abstract: Techniques for providing Hybrid information-centric networking (hICN) via a proxy application is described. A hICN proxy application provides hICN to legacy applications by diverting network traffic of a plurality of network traffic types to the hICN proxy application and storing network traffic information for the network traffic in a connection table. The hICN proxy application also translates the diverted network traffic to a hICN network traffic protocol and selects a forwarding strategy for the translated network traffic in order to send the hICN traffic over various non-hICN network protocol types. The hICN proxy application also transmits the translated traffic to a server proxy application using the selected forwarding strategy.Type: GrantFiled: August 18, 2020Date of Patent: September 6, 2022Assignee: Cisco Technology, Inc.Inventors: Michele Papalini, Jordan Augé, Giovanna Carofiglio, Luca Muscariello, Mauro Sardara, Xuan Zeng

Patent number: 11121642Abstract: The disclosure discloses a simplified space vector modulation method for multi-lever converters, and relates to the field of space vector modulation methods for multilevel converters, which solves problems that a redundant on-off state is greatly increased along with increase of a number of levels in a traditional SVM technology, and SVM is difficult to realize due to calculation of the redundant on-off state and selection of a proper on-off state. The method includes the following steps of: step 1: establishing a vector expression; step 2: establishing a reference vector trajectory model; step 3: respectively representing reference signals and level signals by coordinate components of a reference vector and a basic vector and corresponding component sums; step 4: constructing a star-connected multilevel converter; step 5: sampling a phase voltage reference vector trajectory model of the star-connected multilevel converter, and synthesizing the reference vector.Type: GrantFiled: October 1, 2020Date of Patent: September 14, 2021Inventors: Cui Wang, Junming Ouyang, Xuan Zeng, Xingwang Zhang, Zhikai Huang, Xiaopin Yang, Jianghua Gan, Sizhe Chen

Patent number: 11038899Abstract: Presented herein are methods for dynamic management of names and of named-based requests for media flows in an Information-Centric Network (ICN)-based real-time communication system. The use of different naming schemes on contribution segments and on distribution segments in such architectures results in an effective low latency and scalable communication model based on the notion of active speakers regardless of the underlying mapping between active speakers and participants controlled by the media bridge. Operations are performed both at client side and at media bridge side to dynamically manage binding of names to speakers, while minimizing overhead and complexity of operations involved by a change of active speaker/quality/layout.Type: GrantFiled: September 8, 2020Date of Patent: June 15, 2021Assignee: CISCO TECHNOLOGY, INC.Inventors: Giovanna Carofiglio, Michele Papalini, Jacques Olivier Samain, Xuan Zeng, Luca Muscariello, Carl Nathan Buckles

Patent number: 9098649Abstract: An dual function distance metric for pattern matching based hotspot clustering is described. The dual function distance metric can handle patterns containing multiple polygons, is easy to compute, and is tolerant of small variations or shifts of the shapes. Compared with an XOR distance metric pattern clustering, the dual function distance metric can achieve up to 37.5% accuracy improvement with 2×-4× computational cost in the context of cluster analysis. The dual function distance metric is reliable and accurate for characterizing clips (e.g. hotspots), thereby making it desirable for industry applications.Type: GrantFiled: June 17, 2013Date of Patent: August 4, 2015Assignee: Synopsys, Inc.Inventors: Charles C.
