The embodiment of the invention provides a cleaning method of cleaning equipment and the cleaning equipment, and relates to the technical field of intelligent equipment. The cleaning equipment is provided with a grabbing module, and the method comprises the steps that when the cleaning equipment cleans an operation area, multi-mode environment sensing data of the operation area is acquired; based on the multi-modal environment perception data, the semantic category and the spatial position of a grabbable article are recognized through a visual model, and the grabbable article is one of multiple preset articles; based on the semantic category and the spatial position, generating a grabbing decision instruction for grabbing the grabbable article; and based on the grabbing decision instruction, grabbing the grabbable articles through a grabbing module, and arranging the grabbable articles or placing the grabbable articles in a preset target storage area. Through the method, transition from passive obstacle avoidance to active environment transformation is achieved, the cleaning equipment can accurately recognize the grabbed objects and clean the grabbed objects, the cleaning comprehensiveness is improved, and the cleaning coverage rate and the user satisfaction degree are improved.

The present disclosure provides a method, system, and device for security object synchronization at multiple nodes of an active-active environment. To illustrate, a source node may generate a corresponding security object sync request for each of multiple target nodes. The source node may send the security object sync request to the target nodes via a source queue and, for each target node, a corresponding distribution queue. A distribution queue may be closed based on an acknowledgement received from a corresponding target node, after a time period, or after a number of transmission attempts. A synchronization log may be maintained to indicate which security object sync requests have been delivered to which target nodes. In some implementations, the source node and the target nodes are part of an active-active environment that may be synchronized in time so the nodes resolve conflicts between received security object updates initiated from two different nodes.

A bioreactor with a closed vessel, a reaction chamber, and at least one barrier, wherein the bioreactor is configured to support a biologically active environment. The barrier for the reaction chamber of the bioreactor includes pores and a media flow path connected to the pores. The media flow path is configured to have a diameter that is smaller than the average diameter of the pores. The barrier of the bioreactor includes a surface feature, internal structural feature, or combinations thereof, which are configured to improve or enhance the growth of cells or microorganisms.
