Abstract: Method for producing a label having at least one identifier and at least one authenticator printed on a printable medium. A unique identifier is generated by a centralized system or a printing device, and the unique identifier is printed on the printable medium incorporating the authenticator. The unique identifier is generated without relation to a product. The method is implemented with a system including one or more printing devices, one or more recording devices and one or more activation devices communicating with the centralized system.

Abstract: A method of balancing an electrical distribution system including several generators implements a network divided into several subnetworks powered by ring-like swappers. The balancing of the network between the various generators available is obtained through switchings of subnetworks selected as a function of the order of switching of the swappers.
