Title
(EN) APPARATUS, SYSTEM AND METHOD FOR WIRELESS SLIP RING DATA TRANSMISSION
(FR) APPAREIL, SYSTÈME ET PROCÉDÉ DE TRANSMISSION DE DONNÉES PAR BAGUE COLLECTRICE SANS FIL
Abstract
(EN)
A wireless slip ring, system and method for transmission of data across a rotatable junction can be provided to permit transmission of data from a fixed element to a rotating element across a rotary interface. The wireless slip ring can provide high bandwidth multi-channel data transmission, for example each channel can have a bandwidth greater than 1 gigabit per second. Each channel may include a plurality of input/output data streams that can be serialized by a digital electronic circuit for transmission across the slip ring and then deserialized into its respective data streams. The wireless slip ring can form an annular chamber to act as a wave guide for the wireless signal for providing a continuous conductive covering around the annular chamber to act as a faraday shield to contain radio frequency emissions and prevent external jamming.

La présente invention concerne une bague collectrice sans fil, un système et un procédé de transmission de données à travers une jonction rotative prévus pour permettre la transmission de données d'un élément fixe à un élément rotatif à travers une interface rotative. La bague collectrice sans fil peut fournir une transmission de données multicanal à largeur de bande élevée, par exemple chaque canal peut avoir une largeur de bande supérieure à 1 gigabits par seconde. Chaque canal peut comprendre une pluralité de flux de données d'entrée/sortie qui peuvent être sérialisés par un circuit électronique numérique pour une transmission à travers la bague collectrice, puis désérialisés dans ses flux de données respectifs. La bague collectrice sans fil peut former une chambre annulaire pour servir de guide d'onde pour le signal sans fil afin de fournir un revêtement conducteur continu autour de la chambre annulaire pour agir comme une cage de faraday afin de contenir des émissions radiofréquence et empêcher un brouillage externe.
