ABSTRACT:
Systems transmit a control signal between a rotating element and a stationary element of a blood separation centrifuge. The systems employ a sensor mechanism carried by one of the rotating and stationary elements. The sensor mechanism senses an operating condition that is subject to change. The sensor mechanism generates a first output signal that varies according to changes in the sensed operating condition. A first data transfer component on the one element that carries the sensor mechanism emits energy to the other element without mechanical contact with the other element. The first data transfer mechanism modulates the emitted energy according to variations occurring in the intensity of the first output signal. A second data transfer component on the other element receives the modulated energy emitted by the first data transfer component. The second data transfer component demodulates the detected energy to generate a second output signal that, like the first output signal, varies according to the changes in the sensed operating condition.
