註釋

Modern turbomachinery research and development relies heavily on results obtained from measurement programs preformed for realistic operating conditions. One of the most important of these conditions to capture is the influence of rotation on the local flow physics. Effectively collecting large quantities of accurate and useable data from onboard a rotating piece of hardware, however, has proven to be a challenge. Various rotational to stationary wired transfer techniques, e.g. slip-ring units, have been developed and implemented with degrees of success, but they often increase hardware complexity, cost, and setup time, and still carry physical limitations in the number of channels and electrical current carrying capacity. Another solution, developed decades ago but made feasible for large-scale implementation only recently by advancements in modern electronics, is the wireless transmission of electrical signals from onboard rotating instrumentation.
