This invention discloses a control method, system, device, and storage medium based on inertial sensor attitude calculation, including: acquiring acceleration and angular velocity; calculating motion attitude data based on acceleration and angular velocity; calculating the relative attitude angle change from the motion attitude data; mapping the relative attitude angle change to relative directional displacement to obtain relative directional displacement data and sending it to the host. This application utilizes the feature of existing smart wearable devices equipped with inertial sensing units to convert motion attitude into relative attitude angle changes, providing an attitude calculation method. This application can use BLE wireless transmission, balancing mobility and portability, making it suitable for wearable devices such as smart glasses. Furthermore, this application introduces complementary filtering, dead zone, and output filtering steps into the attitude calculation method, improving the accuracy of attitude calculation. It also adds an automatic calibration step, which can suppress drift and jitter, reducing the false touch rate.

This invention belongs to the field of coal mining technology and relates to an anchor removal device and process based on post-mixed abrasive ultra-high pressure water jet. The device includes: an ultra-high pressure water jet cutter head; a rack, positioned below the ultra-high pressure water jet cutter head, with protruding teeth on its side; a rack conveyor, sleeved on the outside of the rack, with grooves on its inner wall matching the protruding teeth, for conveying the rack upwards or downwards; an abrasive storage tank connected to the ultra-high pressure water jet cutter head via an abrasive delivery pipeline; and an ultra-high pressure water pump connected to the ultra-high pressure water jet cutter head via a water supply pipeline. The anchor removal device of this invention achieves efficient anchor removal operations in confined spaces. Furthermore, during the anchor removal process, the space within the cutting gap and the space around the anchor rod are filled with water, creating a continuous low-oxygen, low-temperature environment. Even when the abrasive hits the anchor rod, no sparks are generated, effectively solving the safety problem caused by sparks easily generated during existing abrasive water jet anchor removal processes.

This utility model belongs to the technical field of electrostatic removal equipment for thin films, and in particular, it is a PVC colored film electrostatic removal device. It includes a support frame and a metal conductive tube fixedly welded to its upper end. A guide groove is laterally formed on the periphery of the metal conductive tube. A metal frame rod is movably connected to the inner wall of the guide groove. A metal sleeve is rotatably fitted around the periphery of the metal frame rod. A metal sleeve rod is fixedly welded to the periphery of the metal sleeve. A metal insert rod is inserted into the inner wall of the metal sleeve rod. A metal grounding block is fixedly connected to the lower end of the metal insert rod. An opening groove is formed at the port of the metal conductive tube. This utility model achieves three-dimensional position adjustment of the metal grounding block through the lateral sliding of the metal frame rod, the rotational adjustment of the metal sleeve rod, and the telescopic design of the metal insert rod. This allows for precise matching of PVC colored films of different sizes and shapes, ensuring maximum electrostatic contact area and significantly improving electrostatic removal efficiency.
