In the present specification, a method for reporting channel state information (CSI), performed by a terminal, comprises the steps of: determining a format type of a physical uplink control chancel (PUCCH) for reporting the CSI according to a CSI feedback type, wherein the format type of the PUCCH isa short PUCCH or long PUCCH; and reporting the CSI to a base station through the determined PUCCH format type.

The invention relates to a knee joint structure used for a lower limb exoskeleton robot. A shank assembly is connected with a thigh assembly through a four-bar linkage knee joint, and a gas spring is further mounted between the shank assembly and the thigh assembly. One end of the gas spring is connected to the thigh assembly, and the other end of the gas spring is in sliding connection with a gas spring sliding groove mechanism fixed to the shank assembly. By utilizing the gas spring to provide assistance, conversion from standing to sitting and conversion from sitting to standing are realized. When a user normally walks, the slip of the gas spring, caused by the bending of the knee joint, cannot reach the bottom of the gas spring sliding groove mechanism, so that the gas spring is not compressed or stressed, and normal walking is not affected. When the user wants to convert from standing to sitting or convert from sitting to standing, the slip of the gas spring, caused by the bending of the knee joint, can reach the bottom of the gas spring sliding groove mechanism, the gas spring is compressed and stressed, and energy is stored, so that assistance is provided for converting from standing to sitting and converting from sitting to standing.

The invention belongs to the technical field of tunneling engineering and particularly relates to a manufacturing method for an end shield of a built-in grout block shield machine. According to the invention, grouted blocks are cut and built one by one via the fixing of adjustable inner tube flanges on a winded whole shell, thus the size precision of the end shield is well ensured, the product quality and the efficiency are improved. As for the shell blanking accuracy, the accuracy is greatly improved as compared with that of the traditional method of calculating key point by using the metal plate feeding function of software, so that the method is beneficial for achieving the conical tube mode of the end shield. Compared with the method of winding the shell section by section and then welding with the grouted blocks, the novel integral-cutting and gradual-embedding form ensures product quality better, and is more stable and more reliable. The plate is wound for one time according to the novel method, however, when the sectional winding method is adopted, the plate winding efficiency will be increased, the manufacturing cost of products is improved, and the production efficiency is reduced,.

The power supply unit constitutes a path for redundant power supply. The power supply unit includes a first storage battery and a second storage battery. The supply line supplies power to a plurality of loads. The power line connects the first storage battery and the power supply line. The first fuse is connected between the power line and the power supply line. The current capacity of the fuse unit becomes smaller / larger than the current capacity of the first fuse depending on whether the potential of the power supply line is higher or lower than the reference potential. The first switch is connected between the second storage battery and the fuse part, and is connected to the power supply line through the fuse part.
