  • Publication number: 20210160058
    Abstract: This application discloses a method used to remove a target blockchain node group of a first tenant from a channel. In the method, an execution node of a second tenant receives configuration information of the target blockchain node group of the first tenant which is sent by a management node, obtains channel configuration information of the channel from a consensus organization, and generates channel adjustment information based on the channel configuration information and the configuration information of the target blockchain node group. The execution node of the second tenant sends the channel adjustment information to the consensus organization, and the consensus organization generates a block including the channel adjustment information. A blockchain node group of the second tenant obtains the block from the consensus organization, and adds the block to a blockchain stored in the second tenant.

  • Publication number: 20200387503
    Abstract: A blockchain maintenance method adds a target blockchain node group of a first tenant to a channel. In the method, a management node sends new channel configuration information of the channel to an execution node of a second tenant. The execution node of the second tenant generates incremental configuration information of the channel based on the new channel configuration information and old channel configuration information of the channel, and sends the incremental configuration information to a consensus organization. Each blockchain node group that has joined the channel obtains, from the consensus organization, a block including the incremental configuration information, and adds the block to a stored blockchain, to reach a consensus that the target blockchain node group joins the channel. The target blockchain node group is configured based on the incremental configuration information to join the channel.

  • Patent number: 10783338
    Abstract: Described herein is a system for controlling access to a physical location. In some embodiments, a user device may provide user credentials to an input device of the access system. The input device may transmit the user credentials to a splitter, in some examples, permit access to the physical location via an access control board. In other examples, the input device may transmit the user credentials from a splitter to a network-connected gateway and then permit access to the physical location via the access control board. In either example, the power and signal wires may be reused for the splitter and/or network-connected gateway. The access control board may be coupled with an electrically-controlled device and configured to allow access to the physical location with one or more electronic signals to the electrically-controlled device. The electrically-controlled device may allow access when the user credentials are authenticated by the system.

The electrode system comprises thereon a reagent capable of reacting with a test sample. The electrode system comprises functional electrodes (2, 3, and 4) used for testing and assisted diffusion electrodes (12) used for controlling the diffusion of the reagent. The functional electrodes (2, 3, and 4) are arranged between the assisted diffusion electrodes (12). Because the assisted diffusion electrode (12) are capable of overcoming the effect of surface tension of the insulative base board, the reagent is allowed to diffuse smoothly and uniformly on the electrode system and to arrive at a predetermined position.

  • Publication number: 20160139072
    Abstract: A biosensor and a method for manufacturing the biosensor. The biosensor comprises an insulative substrate (1), an electrode system (2, 3, and 4), a reagent, and an insulating layer (5). The insulating layer (5) covers a part of the electrode system (2, 3, and 4). Also, a closed region (6) without the insulation layer is formed at where the reagent is. The closed region (6) is provided with an enclosing border having no sharp corner. The reagent covers the closed region (6) and does not go beyond the enclosing border. The biosensor also comprises an assisted diffusion electrode (12). The use of the enclosing border having no sharp corner and of the assisted diffusion electrode (12) reduces the edge effect of the reagent, allows the reagent to diffuse uniformly at response areas of the electrodes, effectively controls the amount of reagent used, reduces product costs, and allows for simple manufacturing.

  • Patent number: 8834702
    Abstract: A biosensor for quantifying an analyte in a sample and usage thereof are provided. The biosensor includes an insulative substrate, a cover, a sample supply port, an electrode system including at least a working electrode, a counter electrode and a third electrode, and a reaction layer at least formed over the working electrode. The third electrode, used for estimating whether the amount of the sample is sufficient, is disposed nearer to the sample supply port than the counter electrode is. Whether the amount of the added sample is sufficient is estimated by comparing the electrical current value detected between the working electrode and the counter electrode with the electrical current value detected between the working electrode and the third electrode. This invention has a simple structure and produces accurate measurements.
