Abstract: An electric machine comprising a stator including at least one stator winding elements that extends from a first to a second end, separate from each other; at least one electrical bridge suitable to electrically connect the separate ends of said stator winding element; at least a support and attachment plate made of electrically insulating material which defines at least one seat suitable to house at least partially, and retain in position, the electrical bridge. The seat is provided with attachment mechanisms which form at least partially a shaped coupling with the at least one electrical bridge, so as to mechanically lock it in position on the support and attachment plate. The seat allows the passage of the ends of the stator winding element and the electrical connection between the latter and the electrical bridge. The seat electrically insulates the electrical bridge from other components of the stator.

Abstract: In an instrument panel, a LED backlighting device has at least one LED source, the optical axis of which corresponds to the direction in which the intensity of the emitted light is maximum. The light of the LED source is reflected onto a graphic area by a first and a second reflecting surface. The first surface defines a first cavity and is aligned with the graphic area along an illumination axis spaced apart from the optical axis, while the second surface is aligned with the LED source along the optical axis and defines a second cavity communicating with the first cavity through an aperture. The second surface is a cylindrical surface, defined by an elliptical generatrix and configured so as to block the light rays that would be directed from the LED source onto the graphic area.

Abstract: Method for identifying an incoming vehicle on the basis of images acquired by one or more video-cameras mounted on a vehicle, comprising processing the images in order to identify light spots corresponding to the vehicle lamps, including performing a multi-scale processing procedure to extract bright spots areas from the images and maximum values of the bright spots areas. The method includes tracking positive regions corresponding to the bright spots and independently tracking the bright spots themselves. The tracking of the positive regions is preceded by a classification procedure including generating candidate regions to be classified, and training multiple classifiers, depending on an aspect ratio of the candidate region.
