Abstract: Embodiments of this application provide a three-dimensional map construction method and apparatus, a storage medium, and a chip system, to resolve a current problem that efficiency of constructing a map is low due to vibration of a camera. This application proposes that image compensation processing is performed, based on a capturing time and event data captured by an event camera, on an image frame captured by an RGB camera, to eliminate a problem that an RGB image frame is blurry due to vibration, and improve efficiency of constructing a three-dimensional map and integrity of the map, so that high-precision, efficient, and fast mapping can still be performed in a high-frequency motion scenario.

Abstract: The present invention discloses a modified biological bone mineral scaffold doped based on lithium magnesium phosphate, which is obtained by immersing a calcined bovine or porcine cancellous bone mineral porous scaffold into a solution containing one or more of active metal ions of magnesium, lithium, strontium, zinc, iron and calcium and a phosphorus source composite solution for hydrothermal reaction, baking, drying and calcining at a high temperature. The modified biological bone mineral scaffold doped based on lithium magnesium phosphate obtained in the present invention can effectively stabilize the doped magnesium lithium phosphate and one or more of other osteogenic active ions of strontium, zinc, iron and calcium. The material maintains the three-dimensional interconnected mesh structure and natural crystal structure of the calcined bovine or porcine cancellous bone mineral porous scaffold, and has calcium phosphate crystals containing active ions.

Abstract: The present disclosure discloses a magnetic bead removal method, device, and storage medium, including: placing a liquid bag with a curved flow channel on a magnetic platform, wherein a plane where the curved flow channel is located is above the magnetic platform and parallel to the magnetic platform; controlling a first flow control assembly to communicate the liquid bag with a sample container, thereby inputting a liquid containing immunomagnetic cells and non-magnetic immune cells into the curved flow channel from the sample container; performing a flattening operation on the liquid bag to increase a contact surface between a bottom surface of the curved flow channel and the magnetic platform, thereby adsorbing the immunomagnetic cells in the curved flow channel onto the contact surface through the magnetic platform; and performing a collection operation to collect the non-magnetic immune cells in the curved flow channel into a collection container.

Abstract: A control device for adhesion and detachment is provided and includes a base, an actuator, and a movement mechanism including a bearing unit, a peeling unit, and an adhesion unit. The peeling unit is a thin sheet with a high elastic modulus and has a first side and a second side that are opposite to each other. An upper surface of the peeling unit is fixed on a lower surface of the bearing unit. The actuator is fixed to the first side of the peeling unit. The adhesion unit is arranged on a lower surface of the peeling unit. The peeling unit bends and elastically deforms from the first side towards the second side under an action of the actuator in such a manner that the adhesion unit moves synchronously. The peeling unit is in a flat state upon a recovery from the elastic deformation.
