Patent number: 10474125Abstract: A method is provided for managing optional functions in a screw driving system using a fleet of at least two control hubs, each controlling at least one piece of production equipment and being capable of being used with at least one optional function. Each control hub stores non-differentiated tokens. The optional function is assigned a pre-defined weight, corresponding to a number of tokens. The optional function is pre-installed and deactivated in the control hub. The optional function can be selectively activated on the control hub if the control hub has available a number of tokens greater than the weight of the function, a quantity of tokens corresponding to the weight being debited from the number of tokens available to the control hub, and the function can be selectively deactivated. The quantity of tokens are then made freely usable. Two control hubs can transfer non-differentiated tokens to each other.Type: GrantFiled: December 11, 2017Date of Patent: November 12, 2019Assignee: ETABLISSEMENTS GEORGES RENAULTInventors: Laurent Macquet, Gatien Butstraen, Nicolas Bocquet
