ABSTRACT:
A centrifuge system and method includes generating a radio frequency excitation field within a housing containing a rotor of interest. The excitation field may be generated by an exciter coil fixed to the cover of the housing. The rotor includes a locking knob that encloses a receiver coil inductively coupled to the exciter coil. The excitation field causes current flow through the receiver coil. The current is rectified and used to power encoding circuitry. The encoding circuitry produces a modulated signal unique to the rotor or to a model in which the rotor is classified. The encoded signal is transmitted from within the locking knob to a reader coil connected to the housing of the centrifuge. The reader coil receives the encoded signal, whereafter the signal is decoded and used to identify the rotor or rotor model.
