Abstract
A data transmission system that includes a transmitter; a receiver; and a magnetically coupled rotary transformer having a first portion and a second portion in moveable relationship with one another. The transmitter is electrically and mechanically coupled to the first portion of the rotary transformer, and the receiver is electrically and mechanically coupled to the second portion of the rotary transformer. The transmitter and the receiver are configured to wirelessly communicate data across the rotary transformer while the first and the second portions of the rotary transformer are in relative rotary motion.
