Abstract: A battery pack includes: a housing assembly; plurality of cells disposed in the housing assembly; a circuit board disposed in the housing assembly and connected to the plurality of cells; and at least two electrical terminals connected to the circuit board and configured to be coupled to an apparatus terminal on an external device when the battery pack is connected to the external device. The at least two electrical terminals include a Type-C terminal and a metal terminal fixed on a terminal block, where output power of the Type-C terminal is greater than 65 W, a power device for supplying power to the Type-C terminal is disposed on the circuit board, and the terminal block and the power device are disposed on the same mounting surface of the circuit board.

Abstract: An interventional control method based on a computer control system. An interventional control system is designed on the basis of an original computer control system; the analog-to-digital conversion unit of the interventional control system receives a signal from the data acquisition module of the original computer control system and said signal is processed by a control processing unit according to a built-in program; then a digital-to-analog conversion unit performs digital-to-analog conversion on the signal output by the control processing unit and then outputs a signal obtained after the digital-to-analog conversion to the analog-to-digital conversion unit of the original computer control system.

Abstract: A method for ecological utilization of silver carp, including the pretreatment of silver carp and the process of making canned fish surimi. The fish meat of silver carp is processed canned surimi. The fish heads and bones are heated and undergo enzymatic hydrolysis by enzymes, and the residues of the filtration are prepared for fish bone powder. A filtration membrane is used to reduce the volume of the filtrate to 50% of fish surimi and then the filtrate is frozen to ice. The frozen part can be added to fish surimi. The transparent part from membrane filtration was used to produce protein powder or ingredients for beverages. Fish offal can be used to produce protein liquid fertilizer. Fish scales and skins can be used to produce collagen. The method adopts ecological utilization, which makes the silver carp meat used effectively, including its processed wastes. The method is a closed cycle process such that that no pollutants or wastes are discharged during the process.

Abstract: An ELISpot diagnosis kit for NMO and its application are characterized in that, the polypeptide fragment specific to NMO effector T-cell is obtained through topological conformation analysis of aquaporin-4 (AQP-4), followed by the structural analyses of the related polypeptides after combination and rearrangement so as to screen out the brand-new polypeptide fragment suitable for NMO disease diagnosis. In the ELISpot experiment, by utilizing the obtained polypeptide fragment, stimulate the effector T-cell in the NMO disease to secrete IL-4, proving the feasibility and scientific value of that polypeptide fragment in the NMO diagnosis. This method is with strong specificity, high sensitivity and easy operations, and it can be developed into the diagnosis kit for the diagnosis and differential diagnosis of NMO in the clinical examination, laying the foundation for the early discovery and treatment of NMO.
