Abstract
An interface for transferring power and data between a non-rotating body and a rotating body may include a power transfer device coupled to the non-rotating body, and a power receiver coupled to the rotating body and configured to receive electrical power from the power transfer device. The interface may further include a first data transmitter coupled to the rotating body, and a first data receiver coupled to the non-rotating body and configured to receive data signals from the first data transmitter. The interface may also include a second data transmitter coupled to the non-rotating body, and a second data receiver coupled to the rotating body and configured to receive data signals from the second data transmitter. The wireless coupling between the power transfer device and the power receiver may include an inductive coupling, and the first data transmitter and the first data receiver may each include an optical communication device.
