Abstract: A system for controlling a portable tool with autonomous energy source, implementing at least one geo-positioning beacon external to the tool and capable of communicating with the portable tool. The system includes the following elements carried by the portable tool: a receiver, in or on the portable tool, for receiving control information delivered by the at least one beacon; and a processing unit, which determines the presence of the portable tool within or outside at least one pre-determined space, from the control information, communicates with a controller capable of managing the behavior of the tool as a function of the presence of the portable tool within or outside the pre-determined space or spaces and at least one pre-determined production rule.

Abstract: 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.
