The application provides a soft finger based on a giant electro-rheological valve and a soft gripper integrated with driving control, and belongs to the technical field of soft robots. The soft finger comprises a fluid grid layer and a bottom plate layer. The fluid grid layer comprises a main channel and a plurality of grids. Each grid is provided with a branch cavity. The bottom of the branch cavity is provided with an opening. The bottom of the branch cavity of each grid is communicated with the main channel. A branch soft valve is arranged on the side wall of the branch cavity of each grid. A plurality of main channel soft valves are arranged in the main channel. The side wall of the grid at a fixed end is provided with a first giant electro-rheological liquid pipe. The bottom plate layer comprises a second giant electro-rheological liquid pipe and a bottom plate body. The second giant electro-rheological liquid pipe is communicated with the main channel. By applying a specified pressure to different parts of each branch cavity and the main channel, the branch cavity is expanded, a plurality of bending modes of the soft finger can be realized, and the main channel can be individually pressurized to improve the ability of grasping a load.

This invention discloses a lightweight image super-resolution reconstruction method, system, and storage medium, relating to the field of image processing technology. Specifically, it includes: acquiring high-resolution and low-resolution images of the target as training sample pairs; constructing a lightweight image super-resolution reconstruction model comprising a shallow feature extraction module, a deep feature extraction module, a multi-layer feature fusion module, and an image reconstruction module. The shallow feature extraction module performs shallow processing on the low-resolution image; the deep feature extraction module consists of multiple cascaded enhanced separable residual feature refinement blocks, extracting shallow features to obtain multiple deep features; the multi-layer feature fusion module is used to obtain fused features; and the image reconstruction module is used to output the high-resolution image. The trained model is used to reconstruct the low-resolution image to be processed. This invention has a simple network structure and achieves accurate reconstruction of image texture and details using only a low number of parameters and computational cost.

The utility model discloses a high pressure vertebral body dilatation balloon relates to medical instrument technical field, including the cylinder, one side of cylinder is equipped with the communication pipe who communicates with its inside, the communication pipe is connected with the auxiliary pipe away from one end of cylinder, is provided with the joint on the auxiliary pipe, the end portion fixed mounting of cylinder has the balloon, and the outer wall of balloon is circumferentially provided with a plurality of membrane.
