Publication number: 20210172940Abstract: A type of microfluidic platform, photothermal bar-chart chip (PT-Chip), uses on-chip nanomaterial-mediated photothermal effect as a tunable microfluidic driving force to drive ink bar-charts in a visual quantitative readout fashion. The photothermal bar-chart pumping performance can be adjusted remotely by tuning the irradiation parameters, without the need to change any on-chip parameters. The PT-Chip enables a POC visual quantitative diagnostics, by forming nanomaterial-mediated photothermal effects-driven bar-chart microchip for visual quantitative immuno-sensing. In this immunoassay, biomolecules are visually quantified by directly reading the distance that fluids move on the PT-Chip.Type: ApplicationFiled: December 4, 2020Publication date: June 10, 2021Inventors: XiuJun Li, Guanglei Fu, Wan Zhou

Patent number: 9030967Abstract: The present disclosure describes rapid convergence of an Access Network (AN). A VLAN forwarder is allocated to a first Virtual Local Area Network (VLAN) and traffic for the first VLAN is forwarded to and from the AN via the VLAN forwarder. When detecting that the VLAN forwarder satisfies a VLAN reallocation condition, the VLAN forwarder blocks traffic of the first VLAN to and from the AN via the VLAN forwarder, and calculates a characteristic value of the VLAN forwarder. A packet carrying the characteristic value of the VLAN forwarder is transmitted to each neighbor VLAN forwarder such that VLAN reallocation is performed by a VLAN allocator if the characteristic value of the VLAN forwarder is the same as that of each neighbor VLAN forwarder. After receiving information that the VLAN forwarder is reallocated to a second VLAN, the VLAN forwarder allows the traffic of the second VLAN to and from the AN via the VLAN forwarder.Type: GrantFiled: July 4, 2013Date of Patent: May 12, 2015Assignee: Hangzhou H3C Technologies Co., Ltd.Inventor: Wan Zhou
