A MIMO Decision Feedback Equalizer improves operation of a receiver by canceling the spatio-temporal interference effects caused by the Multiple-Input-Multiple-Output channel memory with a set of Finite Impulse Response filters in both the feed-forward and the feedback MIMO filters. According to the invention, the component is embodied such that the whole diffuser is largely arranged in the layer. The apparatus includes a microfluidic cartridge that is configured to accept a plurality of samples, and which can carry out PCR on each sample individually, or a group of, or all of the plurality of samples simultaneously. Moreover, the processor managing unit can be distributed and disposed between the bus and the processors and between the bus and the module. The micro-organisms andor bio-molecules produced in the process, and the proteins, crystals particles or fat droplets being processed are monitored by means of acoustic spectroscopy. The second end of the optical fiber is cleaved at a predetermined position so as to provide for a predetermined length of the optical fiber measured from the first end of the optical fiber to the second end of the optical fiber.
