The rotor structure has primary and secondary heat transferring portions within which a closed fluid flow circuit is embodied. The arms are pivotable, in corresponding fashion, with respect to a side of the platform, between an upper, open orientation and a lower, closed orientation. A synchronous graphics processing pipeline processes the data read from the second bank of memory and provides the post-processed graphics data to the memory controller to be written back to the bank of memory from which the pre-processed data was read. The coating deformation andor a change of one or more optical properties of the optical energy circulating within the micro-cavity are used to detect the presence of the gas or vapor or molecules or particulates thereof.
