Abstract: Described herein is a sensorized glove, in particular designed for ergonomic analysis, including an inner glove, which comprises a plurality of extensometer sensors configured for detecting relative movements between parts of a worker's hand; and an outer glove, which comprises a plurality of pressure sensors distributed over a palmar surface and configured for detecting the pressure exerted in corresponding areas of said palmar surface. Moreover described is a corresponding method for determining the type of grasp exerted by a worker.

Abstract: Described herein is a system and method for ergonomic analysis including a sensorized glove having an inner glove including a plurality of extensometer sensors for detecting relative movements between parts of a worker's hand, and an outer glove including a plurality of pressure sensors distributed over a palmar surface and for detecting pressure exerted in corresponding areas of said palmar surface; a wearable network of sensors being located in the network so that they can be associated to corresponding joints of the human body; a unit for generating a sequence of images of a worker task; and a processing unit for receiving data and/or signals from the sensorized glove, from the wearable sensor network, and/or from the unit, and configured for processing said data and/or signals to estimate ergonomic indicators and/or to obtain local information of effort and/or posture.

Abstract: A spot welding head includes an electrical conductor guided into a tubular sheath whose ends are rigidly connected to rear ends of supporting bodies of several electrodes. The sheath defines a substantially stiff loop portion configured and arranged so as to be substantially parallel and to face an annular path defined by the electrodes and the supporting bodies, in such a way that two magnetic fields, one generated by electromagnetic induction caused by electric current flowing through the electric conductor placed into the loop-shaped sheath, and the other generated by electromagnetic induction caused by electric current flowing through the electrodes and the supporting bodies thereof, substantially cancel each other out or generate an overall magnetic field which is located forward of the rear end of the welding head or forward of the operator's body.

Abstract: A spot welding head is described wherein an electrical conductor for connection of one electrode connection to an electric transformer is guided into a tubular sheath whose ends are rigidly connected to the rear ends of the supporting bodies of the electrodes.

Abstract: A motor-vehicle, particularly an electrically-powered car of small size, has a supporting structure in the form of a reticular framework (2) of light alloy. The framework (2) includes two side structures (3) each formed by extruded profile elements (4) which are welded to joining knot elements (5) which have been obtained by casting. The side structures (3) are connected to each other by cross members (6, 7, 8, 9) which also are formed by extruded profile elements having their ends connected to the side structures (3) by mechanical coupling means, such as screws.
