Patent ID: 8555755

Claim:
Electronic apparatus for controlled fastening, comprising a body ( 11 ) coupled to which is one of different removable inserts ( 17 , 17 ′, 17 ″), each of which is intended to be engaged onto a corresponding type of mechanical member on which the apparatus is intended to operate, and further comprising a sensor ( 20 ) for detecting a torque exerted onto the mechanical member and which emits an information signal transmitted to calculation, means ( 22 ) to obtain, from the signal emitted by the sensor, significant parameters of an action of the apparatus on the mechanical member, mounted on each insert being a transponder ( 18 ) which, when activated, sends signals and present in the body being reception means ( 19 , 23 ) for receiving such signals transmitted by the transponder of the insert coupled to the body and sending them to the calculation means ( 22 ) to influence calculation of said significant parameters for the operation of the apparatus and/or to provide control for presets of operating parameters of the apparatus, the apparatus further comprising in the body, means ( 19 , 24 ) for sending programming information signals to the transponder ( 18 ) and the transponder comprising means ( 25 , 26 ) for receiving such signals and storing them in its memory ( 27 ) as part of signals to be transmitted, characterized in that the means ( 19 , 24 ) for sending programming information signals to the transponder ( 18 ) are connected to the calculation means ( 22 ) for receiving operative parameters obtained by the calculation means ( 22 ) according to the information signals emitted by the torque detection sensor ( 20 ), sending such operative parameters to the insert ( 17 ) and storing them in a memory ( 27 ) thereof.
