Title: Self-folding scooter. The invention relates to a scooter comprising a front part (1) and a base part (2) connected by a joint (3) to move the scooter from an unfolded configuration to a folded configuration in which the base part (2) is folded towards the front part (1). It includes: - a motor (17), - a locking system capable of moving from a locked position, in which the base part (2) is immobilized relative to the front part (1) in the unfolded configuration, to an unlocked position, - a control system for moving the locking system from the locked position to the unlocked position, and then for activating the motor (17) so as to rotate the base part (2) to reach the folded configuration.

A self-folding and / or self-rolling fabric, such as, for example, a towel or the like, comprises an internal structure of a memory material such as, for example, a metal or metal alloy wire, a metal or metal alloy foil, a polymeric material, or combinations thereof having a memory. When the memory material is heated, such as within a common heat-generating clothes dryer, the memory material reforms into a shape, thereby imparting the shape onto the fabric.

This invention discloses a method and system for processing multi-layer thickness images in UV printing. The method includes acquiring the target thickness intention, outputting a three-dimensional joint instruction tensor of droplet volume, droplet temperature, and UV light intensity via a generative adversarial network (GAN), and then performing multi-physics collaborative printing based on this tensor. At the pixel level, the method independently controls the droplet temperature of each nozzle and the UV light intensity of each pixel, achieving differentiated modulation such as high stacking, tiling, and edge barrier walls. An error map is obtained by measuring the actual thickness in situ and calculating the expected thickness using a differentiable physical proxy model. This error map is then processed through a three-layer closed loop to achieve real-time correction, GAN update, and fine-tuning of the tactile mapping model. This invention significantly improves thickness control accuracy, substrate adaptability, and printing efficiency, and can be applied to various scenarios such as 3D relief, micro-optical components, functionally graded materials, and 4D self-folding.

The invention belongs to the technical field of hinges, and particularly relates to a hinge and a damping assembly thereof, the damping assembly comprises a base and a rotating shaft, the base comprises a mounting plate and an elastic piece which form a clamping space, a cam interacting with the clamping space is formed on the rotating shaft, the rotating shaft is used for being connected with an external mounting plate, and the external mounting plate is used for mounting a shell; the shell is provided with the flexible screen, and the rotating shaft rotates to drive the external mounting plate to drive the shell and the flexible screen to be folded synchronously, so that folding and unfolding of the folding type electronic equipment are realized. In the application, the rotation partition of the hinge is realized through the clamping space and the cam, that is, the rotation included angle is smaller than the self-folding angle, the rotation included angle is between the self-folding angle and the self-unfolding angle and larger than the self-unfolding angle, so that the electronic equipment has different use states, different use requirements are met, and good practicability is achieved.

The utility model relates to saliva packaging ware technical field, and disclose a saliva enzyme control self -folding packaging ware, the rubber or silica gel sealing ring of inside preset in the existing technology generally relies on the sealing cover, the extrusion effect of screwing with the cover body is used, let sealing ring and pipe mouth adhere to form seal, the sealing function is relatively simple, the utility model discloses through setting up reinforcing component, after saliva collection good will join in the packaging pipe body, then again the sealing cover body rotation installation is to the packaging pipe body, to constitute the complete packaging ware, the saliva that adds to the packaging pipe body will continue to degrade support film body, through the stress difference of support film body degradation, make the packaging pipe body along the crease folding, the process of folding boss body moves to the sealing cover body place, finally make boss body insert to the concave platform body and take place slight deformation, to this increase the sealing performance of whole device.

This application relates to a method and apparatus for self-folding origami structures based on a twisted-pair driver. The method includes: placing a twisted-pair driver on a ring-shaped base and forming an origami structure at the center of the base; calculating the threading method of the self-folding scheme based on the crease distribution characteristics of the origami structure and the displacement constraint principle under quasi-static conditions; threading the wires according to the threading method in the actual origami structure, and enabling the twisted-pair driver after threading, so that the wires are twisted together by the rotation of the motor of the twisted-pair driver, and the actual origami structure is folded by the force generated by the displacement constraint. This solves the problems of related technologies being difficult to apply to folding large-sized origami structures or origami structures with high stiffness at the creases, and having problems such as stringent environmental requirements, insufficient driving force, system complexity, and high manufacturing costs.

This invention relates to a minimally invasive transcatheter valve leaflet folding repair device, belonging to the field of medical device technology. It includes a capture clip, a folding clip, a traction mechanism, and a stop mechanism. One end of the capture clip has a movable, openable and closable clamping arm, and the other end has a traction mechanism for pulling the clamping arm.
