A device for communication between a vehicle and one of its wheels comprises a housing containing an electronic circuit and capable of pressing against a rim of the wheel during fitting of a valve to said rim. A display picture data is obtained from a video buffer of the first screen. The system retrieves an initial file or image that is to be compressed and determines a target bit rate corresponding to the compressed file. A combined stream is formed from the first and second streams, gradually converged, and discharged from the mixing chamber through a mixing chamber exit port. 5 dB optical loss to the amplifier site; a second amplification medium located down-stream from the first amplification medium; and at least another one optical signal loss element, this at least another one optical signal loss element being located between said first amplification medium and said second amplification medium. An eccentric threaded stud support is adjustively rotatable to position the eccentrically retained stud at a plurality of caster angle defining orientations extending from zero caster negatively or positively.
