ARRIERE PLAN TECHNOLOGIQUE BACKGROUND

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 type in question comprise a rotary joint which transmits the electrical energy, the video signal and the 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 of 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 elevation motor of the axis is connected to the rotary joint by means of mechanical moving parts that have the effect of reducing the reliability of the corresponding mechanical connections.

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