  • Patent number: 11119064
    Abstract: An impedance spectroscopy biosensor is provided that is fabricated on a stretchable substrate. The stretchable substrate is integrated with an impedance biosensor that undergoes cyclic strain without cracking. The biosensor is formed by curing an elastomer precursor while on a pre-tensioned membrane that includes a conductive electrode. The resulting elastomeric material is released from the support after curing which releases the pre-tensioned state to produce the biosensor.

  • Patent number: 11063859
    Abstract: Embodiments provide a packet processing method. In accordance with this method, a first LSP packet can be received by a network device. The following determinations can be made: that the network device stores no LSP packet whose LSP ID and PDU type are the same as an LSP ID and PDU type of the first LSP packet; that the network device has stored a second LSP packet whose LSP ID is the same as an LSP ID of the first LSP packet and PDU type is the same as a PDU type of the first LSP packet, and that a sequence number of the second LSP packet is less than a sequence number of the first LSP packet. When one or more of these determination are made, a determination whether LSP packet digest information matching the first LSP packet exists can be made. When the LSP packet digest information matching the first LSP packet is determined to exist, the first LSP packet can be stored.

  • Patent number: 10892982
    Abstract: This application provides a method for updating a route in a network. The first network device sends a first LSA packet to a third network device, so that the third network device generates a first route whose destination address is a second IP address, where a next-hop IP address of the first route is the IP address of the first network device, and the second IP address belongs to the IP network segment corresponding to the first IP address which is an IP address of the first network device. The first network device sends a second LSA packet to the third network device when determining that switching needs to be performed on a next hop of a route in the third network device, whose destination address belongs to the IP network segment, and whose next-hop IP address is the first IP address.

  • Patent number: 10724485
    Abstract: There is provided a manufacturing method of a hollow composite magnetic member having weakened magnetism in a portion of a ferromagnetic hollow member, the method includes: a step of forming a weak-magnetic area having weakened magnetism by melting and mixing a Ni-containing material and the hollow member by continuously supplying the Ni-containing material to a portion of the hollow member and heating the irradiation area having a line segment shape with the laser beam. Accordingly, since it is possible to prevent drop of a local portion of a hollow ferromagnetic pipe from being easily generated by a weak-magnetization treatment, to greatly reduce deformation generated by laser irradiation, and it becomes unnecessary to adjust the shielding gas pressure inside the pipe, the weak-magnetization treatment can be performed with higher efficiency and higher quality.
