  • Publication number: 20240067516
    Abstract: 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.

  • Patent number: 11438431
    Abstract: 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.

  • Patent number: 11121642
    Abstract: 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.

  • Patent number: 11038899
    Abstract: 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.

  • Patent number: 9528120
    Abstract: The present invention relates to synthetic promoter and a synthetic gene which confers broad-spectrum disease resistance to Xanthomonands in plants. The present invention also relates to transgenic plants containing the synthetic gene and plants derived by crossing plants with such transgenic plants. More specifically, the synthetic promoter is a synthetic Xa10 promoter and the synthetic gene is a synthetic Xa10 gene which contains the synthetic Xa10 promoter. The resistance is resistance to bacterial blight and the plants are rice plants.

  • Patent number: 9098649
    Abstract: 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.
