A pre-configured implant cover fabricated from a drug-eluting biocompatible matrix containing at least one elutable drug, a kit containing at least one elutable drug implant cover, and a method of using the same. The metal plate has an outer peripheral region which is drawn out laterally from the base body, from the ground conductor region to the attachment region along an outer periphery of the base body. For road information, a current running area is decided based on information in the current position of a vehicle and information about a road over which the vehicle has already run or the same information and information about the forward place of the vehicle. The holding member has a guide groove for guiding the engaging portion to the receiving portion, the guide groove extending from an end portion of the holding member along a first direction in which the holding member extends. Each wing forms a lateral supporting surface for the base of the open lower end, which allows tilting of the panel in a preset direction, with the retention elements in the configuration for releasing the panels. The input may include a first parameter specifying metadata criteria for metadata of the fragment.
