Abstract
Various examples are directed to a rotary coupler and methods of use thereof. The rotary data coupler may comprise a transmitter and receiver. The transmitter may comprise a first band and a second transmitter band. The receiver may comprise a receiver housing positioned to rotate relative to the first transmitter band and the second transmitter band. A first receiver band may be positioned opposite the first transmitter band to form a first capacitor and a second receiver band may be positioned opposite the second transmitter band to form a second capacitor. The receiver may also comprise a resistance electrically coupled between the first receiver band and the second receiver band and a differential amplifier. The differential amplifier may comprise an inverting input and a non-inverting input, with the non-inverting input electrically coupled to the first receiver band and the inverting input electrically coupled to the second receiver band.
