3results about How to "Reduce acquisition error" patented technology

This application relates to a UAV frame for bridge inspection, belonging to the technical field of UAVs. It includes a UAV body with a connecting frame at its bottom. This application utilizes a plug-in engagement between a plug and the connecting frame, and a limiting block driven by a push spring in a snap-fit ​​assembly to achieve automatic initial positioning. Simultaneously, a bidirectional lead screw driven by a first servo motor in the limiting assembly drives a moving frame and its locking block for a secure secondary locking. This significantly simplifies the installation and disassembly process of the UAV body and the connecting frame. Furthermore, a buffer assembly located on the outside of the connecting frame, with its support plate sliding within the damping sleeve of the support leg via a slide rod, compresses the buffer spring. This effectively absorbs and dissipates the impact energy generated during UAV takeoff and landing or sudden collisions, maximizing the protection of the precision components inside the UAV body and the shooting and detection devices within the mounting frame. This significantly reduces data acquisition errors and improves operational safety and data reliability.

This invention relates to the field of vision acquisition technology, specifically to an intelligent vision acquisition system based on automatic calling. The system includes a non-slip seat and a vertical backrest. The vertical backrest is fixedly installed on the rear surface of the non-slip seat and perpendicular to its upper surface. A response control box is fixedly installed above the non-slip seat, and a lifting adjustment cylinder is fixedly installed on the rear surface of the vertical backrest. A screw drive structure is located above the lifting adjustment cylinder. This invention enables the subject to complete vision acquisition independently through automatic calling, requiring no staff assistance and significantly reducing manpower requirements. It also offers better acquisition accuracy. The screw drive structure, in conjunction with an electronic display panel, displays vision test symbols of different sizes. The system's proximity adjustment, combined with the screw drive structure, accurately determines the subject's vision status.
