Abstract: A handlebar for a vehicle. The handlebar includes: a bar having a coupling end; an end piece that longitudinally extends the coupling end; an electronic processing unit housed in the bar; an antenna for transmitting and receiving electronic data coupled to the electronic processing unit, intended to allow an exchange of electronic data with a telecommunication network; and a receiver of a satellite navigation and positioning system, the receiver being coupled to the electronic processing unit. The antenna and the receiver are housed in an external part of the end piece, the antenna being interposed between the receiver and the coupling end.

Abstract: A handlebar for a vehicle. The handlebar includes: a bar having an internal volume, the bar extending longitudinally between two ends, at least an end of which, referred to as a “coupling end” has a central axis, and is open to form a passage between the internal volume and an external environment; and a watertight closure at the coupling end.

Abstract: A method for guiding a cyclist on a bicycle equipped with a bicycle handlebar. The method includes: on each side of a central zone in which the bicycle handlebar is attached to the bicycle handlebar stem, separately illuminating a proximal light-emitting zone located next to the central attachment zone or a distal light-emitting zone depending on the route to be followed.

Abstract: The invention relates to a process for the preparation of a superconductor material of the mixed oxide type, such as oxides of the YBaCuO and Bi.sub.2 Sr.sub.2 CaCu.sub.2 O.sub.8 type. This process consists of the deposition by electrolysis on a conductive substrate of successive layers of metallic elements entering in the constitution of the superconductor material, using a single element in each layer and carrying out, following the deposition of at least one of the layers, an intermediate oxidation-reaction heat treatment for fixing the element of said layer before depositing the following layer, optionally repeating one or more times at least part of the aforementioned operations, and subjecting all the layers to a final, oxidation heat treatment to form the mixed superconductor oxide.
