Abstract: The present disclosure proposes a method and apparatus for image transmission for three-dimensional (3D) scene reconstruction. A target image may be obtained. A geometry feature and an appearance feature may be disentangled from the target image. An intermediate image may be reconstructed based on the geometry feature and a reference appearance feature. A difference between the intermediate image and the target image may be determined. The geometry feature may be transmitted to a receiving device for 3D scene reconstruction in response to determining that the difference is lower than a predetermined threshold.

Abstract: Disclosed in the present invention are methods for preparing a CoNi—S@3D-C nanocomposite and a modified battery separator. The CoNi—S@3D-C material synthesized by the method of the present invention is applicable not only to a lithium-ion battery but also to a sodium-ion battery. As the anode for both the lithium-ion and sodium-ion batteries, it exhibits good energy storage performance, maintaining very stable performance even under high-density current charging and discharging cycles, while also possessing very high reversible capacity. The heteroatom-doped three-dimensional nanocarbon structure achieves good encapsulation of the metal sulfides, and can effectively inhibit the volume expansion of the metal sulfides, slowing down the decline of its specific capacity and maintaining the high capacity and service life of the anode material. The CoNi—S@3D-C material of the present invention can also be used as a material for modifying a separator of a lithium-sulfur battery.

Abstract: A fall protection apparatus has a first cover plate and a second cover plate opposite each other; a rope clamping member located between the first cover plate and the second cover plate and provided with a limit groove as well as a locking position and an unlocking position; a shifting button having a first end connected to the rope clamping member and a second end penetrating through the first cover plate and partially exposed from the first cover plate; and a brake assembly including a pressing portion, a connecting portion, and a brake portion that are connected sequentially. When the fall protection apparatus is in operation, action forces need to be respectively applied from two sides of the fall protection apparatus to the shifting button and the pressing portion, avoiding a mis-operation and preventing the fall protection apparatus from falling off accidentally, thus ensuring operation safety.

Abstract: An insulating container comprises a container body and a container cover connected to the container body. The container body and the container cover each comprises a frame and a plate arranged on the frame. The plate comprises, from inside out, an external high strength sheet, an extruded polystyrene sheet, phase-change insulating sheets made of phase-change material, and an internal sheet. A phase-change process of the phase-change insulating sheets cooperates with a refrigeration system of the transportation device to precisely control the temperature of the insulating container and a refrigerator truck to be near a phase-change temperature. In the present disclosure, the phase-change insulating sheets made of the phase-change material remain to be in a solid state before or after occurrence of a phase change, so that the structure of the insulating container does not change with the phase change and a leakage problem of the phase-change material does not exist.
