Abstract: A trusted storage method and system based on a graph structure are provided. The method includes: in a process of initiating a transaction, randomly selecting, by each transaction initiating node, a plurality of witness nodes from a network for witnessing the transaction; packaging, by the witness nodes, transaction data generated by witnessing the transaction to generate blocks; randomly selecting, by the witness nodes, a plurality of storage nodes; sending, by the witness nodes, the blocks to the plurality of storage nodes; and storing, by the storage nodes, the blocks; wherein, for one transaction, all the blocks of all the witness nodes and all the storage nodes form a directed acyclic graph DAG structure. According to embodiments of the disclosure, the directed acyclic graph DAG structure is employed to be matched with an nRW consensus mechanism, so that a supervision problem in a large-scale sharing and exchanging process is solved.

Abstract: A remanufacturing method for a metal part having a damage. The damage groove is divided into a number of levels, and the groove bottom is treated by absorption layer-free laser shock peening to remove surface impurities and to refine surface-layer crystal grains. Then a cladding layer is formed by laser cladding. The process is repeated until the groove is completely filled by the cladding layer to higher than the surface of the metal part and the cladding layer higher than the surface is cut by a mechanical processing and polished, and the upper surface of the laser cladding layer is subjected to large-area overlapped laser shock peening.

Abstract: A radio frequency generator, includes an input voltage unit, a smart power unit, a voltage acquisition unit, a power amplifier unit, an output unit, a load unit, a current acquisition unit, a processor unit, a signal transmission and drive unit and an input control unit. The present application combined advantages of the high-frequency electric knife and the radio frequency ablation device, can be used for both cutting and coagulating the target tissue, and the ablation or treatment to the target tissue. This radio frequency generator has high versatility, can be used as standard component to produce and manufacture. Different medical radio frequency manufacturers can produce and manufacture their own products to meet clinical needs of different clients and different departments for example, by changing a small quantity of peripheral circuits or software.

Abstract: A method and apparatus for identifying a health status of a contactor includes a processor coupled to a computer readable media. The processor is coupled to the contactor to instruct the contactor to open and close. A database stored in the computer readable media includes operation count variables for the contactor, closing time variables for the contactor, and health status rules for the contactor. The operation count variables and the closing time variables may be inputs to the health status rules to identify the health status of the contactor. A customization program may also be stored in the computer readable media. The customization program enables an operator to modify at least one of the operation count variables, the closing time variables, and the health status rules to affect the identified health status of the contactor.
