Abstract: A battery is provided with a protective body. The protective body is configured to protect an electronic component provided on a circuit board body, so as to reduce probability of the electronic component being subjected to impact, and provide buffering for the electronic component upon impact, thereby reducing the risk of falling-off or damage of the electronic component.

Abstract: Provided is a method for reverse real-time matching based on event-driven graph patterns. The method includes definition of a graph pattern, establishment of reverse matching architecture and a reverse matching method; and the graph pattern is used for describing a spatial connection relationship among vertices and edges in a graph in a reverse order and attribute constraints thereof, and includes a linked list of matching steps and matching contexts. Reverse real-time matching of the graph pattern is realized according to the reverse matching architecture, and the problem of event-driven subgraph matching in a real-time scene is solved.

Abstract: A packaging structure including an accommodating portion and a sealing portion is disclosed. The accommodating portion includes a first wall and a second wall facing each other, a first side wall connected to the first wall and the second wall, and, a second side wall connected to the first wall and the second wall. The second side wall intersects with the first side wall at a first side. The sealing portion includes a first sealing portion connected to the first side wall, a second sealing portion connected to the second side wall, and a third sealing portion connecting the first sealing portion and the second sealing portion. The first sealing portion is folded in a direction away from the second wall. The second sealing portion is folded toward the second wall.
