Abstract: A method and apparatus for controlling the deposition of elementary semifinished products in a process for building tires for vehicle wheels includes: driving in rotation, around a rotation axis, at a rotation speed between about ?/8 rad/s and about 6? rad/s, a tire being processed which tire has a radially external surface including one or more elementary semifinished products; sending a first electromagnetic radiation to the radially external surface, the latter generating a corresponding first reflected radiation; detecting, through a first detecting device, at least one first image representative of the first reflected radiation; controlling the first detecting device in such a manner that a first exposure time for detecting the at least one first image is included between about 0.1 s and about 10 s; carrying out a first comparison between the at least one first image and one or more reference data; and generating a first notification signal as a function of the first comparison.

Abstract: A method of controlling the deposition of semifinished elements for tire production, includes: sending a first radiation onto one tire being processed, consisting of one forming support with at least one portion of the tire component laid on the support, the tire component being at least partly formed of a plurality of semifinished elements defining a radially external layer of the tire being processed; receiving a first reflected radiation from a radially external surface of the tire being processed; determining, as a function of the reflected radiation, parameters representative of the thickness of the layer; comparing the parameters with reference values; and generating an alarm signal as a function of the comparison.

Abstract: Method and apparatus for controlling the movement of building members of a tyre in a process for manufacturing tyres for vehicle wheels includes: providing a first device of a first electromagnetic radiation on a first tyre building member; detecting, during a movement of the first building member, a first image in which the first electromagnetic radiation defines a trajectory followed, in the movement, by the first emitter device; carrying out a first comparison between the first image and one or more first reference data; and generating a first notification signal as a function of the first comparison.

Abstract: A system for generating electrical energy from sea waves comprising a floating body and a gyroscope structure (4) set thereon and comprising: —a first frame (6) mounted so that it can turn with respect to the floating body about a first axis of rotation (E); and —a rotor (8), which is mounted so that it can turn about a second axis of rotation (?), is carried by said first frame, and is substantially orthogonal to said first axis; said system further comprising electric-generator means (14) operatively connected to said first frame for generating electrical energy as a result of rotation of said first frame about said first axis (E). The system comprises actuator means (22, 24, 26; 14, 32, 34) designed to control rotation of said first frame about said first axis, as a function of the angular position of said first frame in such a way that in operation said first frame will perform complete rotations through 360° about said first axis.
