ARRIERE PLAN TECHNOLOGIQUEBACKGROUND TECHNOLOGY

Les dispositifs connus du genre en question comportent un joint tournant qui transmet l'énergie électrique, le signal vidéo et les signaux de télécommande au moyen de surfaces conductrices en contact.  Known devices of the kind in question include a rotary joint which transmits electrical energy, video signal and remote control signals by means of conductive surfaces in contact.

Un tel type de joint présente l'inconvénient majeur lié à l'usure et à l'oxydation desdites surfaces.  Such a type of seal has the major disadvantage related to the wear and oxidation of said surfaces.

En outre, l'axe du moteur de site est relié au joint tournant au moyen de pièces mécaniques en mouvement qui ont pour effet de diminuer la fiabilité des liaisons mécaniques correspondantes.  In addition, the axis of the site engine is connected to the rotary joint by means of moving mechanical parts which have the effect of reducing the reliability of the corresponding mechanical links.

Enfin, leur conception est plus complexe et nécessite des usinages ayant des répercussions sur le temps et le coût de réalisation.  Finally, their design is more complex and requires machining having repercussions on the time and cost of implementation.
