The invention relates to a pantograph (1) of a railway vehicle comprising a lower arm (8), an upper arm (9) articulated to the lower arm (8) and displacing a current collection head (7) to which it is fixed at an end of the upper arm (9), means for conduct...

A pantograph for an electric-driven vehicle includes frame (1) electrically insulated from the vehicle where on eccentric shaft (3) girder (4) is mounted pendulously and the said girder is connected by means of an articulated joint with at least upper arm ...

Since an image processing unit (5A) for determining the acceleration of a pantograph by processing the image of a marker captured by a line sensor camera (2) comprises a input image creating unit (5a) for creating an input image, a template setting unit (5...

The device (18) is intended to monitor condition of a railway supply line when the supply line is in contact with a head (14A) of a pantograph (14) of a vehicle (10) in order to power said vehicle (10). The device (18) includes a camera (26) for monitoring...

In a device for measuring vertical acceleration of a pantograph by photographing an image of a pantograph by a line sensor camera (1) mounted on a vehicle body and calculating the vertical acceleration of the pantograph in an image processing portion (2) b...

Convex curvature of the underside (14) causes the slipstream in each direction (S,K) of travel, to flow more rapidly under the lower side than over the upper side.
