Original Abstract Submitted
a sensing device includes a stationary portion and a rotating portion. the rotating portion is spaced apart from the stationary portion by a gap and is configured to rotate relative to the stationary portion. the rotating portion includes one or more sensors that generate data. a communication interface in the rotating portion is configured to encode the data with error correction codes to provide encoded data, modulate a radio frequency (rf) signal that includes a plurality of sub-carriers with the encoded data to provide a data-modulated rf signal (e.g., an orthogonal frequency-division multiplexing (ofdm) signal), and transmit the data-modulated rf signal to the stationary portion via a wireless data transformer. the wireless data transformer includes a first conductive structure in the stationary portion and a second conductive structure in the rotating portion. the first and second conductive structures are inductively coupled together across the gap.
