Abstract: A guiding signs system may include a plurality of guiding signs for outputting information and an information processor to acquire marching needs and path sets of objects, wherein the marching need includes quantities of objects and the path sets include all passages from a starting point to an end point; the passages include nodes and roads in between, and each node has one or more guiding signs, wherein the information processor calculates each object's distribution in the path sets according to the marching needs, and determine each object's priority on each road according to each object's distribution in the path sets, each guiding sign is configured to output the information of each object's priority on each road.

Abstract: A cover assembly and a battery comprising the same are provided. The cover assembly comprises: a cover plate body formed with at least a via hole penetrating therethrough; a cover plate connecting member hermetically connected with the cover plate body at the via hole, which is formed with an electrode receiving hole therein; and an electrode terminal penetrating through the electrode receiving hole to be hermetically connected with and insulated from the cover plate connecting member for leading out a current.

Abstract: An electrode terminal, a cover assembly and a battery comprising the cover assembly are provided. The electrode terminal comprises: a terminal pole portion, and a pole cap portion formed on an end of the terminal pole portion, and a buffering structure disposed on a surface of the pole cap portion facing to the terminal pole portion.
