Abstract: A silicone pressure sensitive adhesive composition is curable to form a silicone pressure sensitive adhesive. The silicone pressure sensitive adhesive composition can be coated on a substrate and cured to form a topside protective film. The topside protective film can be used to protect an anti-fingerprint hard coating in a screen protective film on cover glass for a display device, such as a smartphone.

Abstract: An electrode assembly and a lithium ion electric roll having the same are provided. The electrode assembly includes: a first electrode unit; a first anti-puncture cushion; in which the first electrode unit includes a first electrode sheet, an second electrode sheet, and a separator, the second electrode sheet comprises a second top edge and a second bottom edge along the length direction of the first electrode unit; an edge of the first anti-puncture cushion exceeds the second electrode sheet from the second top edge or the second bottom edge along the length direction of the first electrode unit.

Abstract: The present disclosure provides a visual model for image analysis of material characterization and analysis method thereof. By collecting and labeling big data of microscopic images, the present disclosure establishes an image data set of material characterization; and uses this data set for high-throughput deep learning, establishes a neural network model and dynamic statistical model based on deep learning, to identify and locate atomic or lattice defects, and automatically mark the lattice spacing, obtain the classification and statistics of the true shape of the microscopic particles of the material, quantitatively analyze the tissue dynamics of the material.

Abstract: A transmission shaft automatic connection and disengagement device and test equipment. An input shaft drives a transmission shaft to rotate through a second connection shaft, a ratchet assembly, a first connection shaft and an output shaft so as to apply an acceleration torque, gears of the input shaft and the first connection shaft can be completely engaged and completely separated through extension and retraction of piston rods of a first group of air cylinders and a second group of air cylinders so as to achieve an effect that when a driving shaft needs to perform driving, a power system gets involved, and after driving is completed, the power system is cut off, and through the ratchet assembly, the transmission shaft can be prevented from driving a motor to work in reverse.

Abstract: The application relates to a wheel with a sound absorption device, wherein the sound absorption device is arranged in a wheel air chamber to reduce acoustic resonance, the sound absorption device comprises two resonance sound absorption structure units which are connected in parallel, a first sound absorption frequency band of a first resonance sound absorption structure unit and a second sound absorption frequency band of a second resonance sound absorption structure unit are adjacent to each other or partially overlap with each other, and the resonance frequency of the wheel air chamber is contained at the adjacent part of the first sound absorption frequency band and the second sound absorption frequency band or in the overlapping area of the first sound absorption frequency band and the second sound absorption frequency band.
