Abstract: A handle control provided with: a supporting body, which is provided with a central through hole and is adapted to be fitted about a handlebar to be rigidly fixed to the handlebar; a twist grip, which has a tubular shape, is rotationally carried by the supporting body and is centrally perforated to be fitted about the handlebar so as to rotate with respect to the handlebar; and an angular position sensor, which is adapted to read the angular position of the twist grip; the angular position sensor has at least one rotor, which is supported by the twist grip to rotate along with the twist grip and is adapted to influence an electric field; and at least one reader, which is carried in a stationary position by the supporting body, is arranged close to the rotor, and is suitable for a contactless and remote reading of the orientation of the rotor.

Abstract: A combined actuator provided with: a mobile element; a driver for displacing the mobile element; and a rheological control brake, which is mechanically coupled to the mobile element to adjust the displacement of the mobile element; the rheological control brake has: two contiguous adjustment chambers; a rheological fluid contained in the two adjustment chambers; a sliding piston, which tightly separates the two adjustment chambers and is mechanically connected to the mobile element; at least one external connection pipe, which reciprocally connects the two adjustment chambers; and a driving device which is coupled to the external connection pipe so as to apply a variable electromagnetic field to the rheological fluid contained in the external connection pipe for varying the viscosity of the rheological fluid between a minimum value and a maximum value.

Abstract: An actuator having a fixed part, a movable part movable with respect to the fixed part in a travelling direction, and a non-contact position sensor connected to the movable part to read the position of the movable part. The position sensor has a reading device connected to the fixed part and having a ferromagnetic core; and a magnetic cursor, which is integrated in the movable part, is defined by a magnetized portion of the movable part, and is so magnetized as to locally saturate the ferromagnetic core at the magnetic cursor.

Abstract: A throttle control provided with: a twist grip, which has a tubular shape and is centrally perforated to be fitted about a tubular handlebar so as to rotate with respect to the tubular handlebar; and an angular position sensor, which is adapted to read the angular position of the twist grip and has at least one rotor, which is supported by the twist grip to rotate along with the twist grip and is adapted to affect an electric and/or magnetic field, and at least a reader, which is adapted to be mounted in a fixed position inside the tubular handlebar so as to be arranged close to the rotor, and is adapted to remotely and contactlessly read the orientation of the rotor.
