Abstract: A method for assisting maintenance of an industrial tool (e.g., a screw driver or drill), implementing rotationally mobile components. The method includes: obtaining measurement data representing an angle and/or a torque during use of the tool; analyzing the measurement data to determine quality data representing possible disturbances induced for each of a set of controlled components, delivering a tool signature; storing the signature in a memory associated with the tool, and readable contactlessly at short distances; remotely reading the signature in the memory, by a terminal; identifying a component requiring action, based on the signature; obtaining, through the terminal, an intervention to be carried out, comprising 3D information on the tool; taking an image of the tool, by a camera on the terminal; displaying a representation in augmented reality, by using the image and the 3D pieces of information, identifying a defective component and/or maintenance operations to be performed.

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.
