The present invention relates to a light guide plate, and a backlight unit and display device including the same. The invention gathers data from that monitored OSSBSSBSM arising from a distinct knowledge of the OSSBSSBSM’s anatomy including its behaviour, log messages, configuration and public APIs and analyses that data to determine the OSSBSSBSM’s run and configuration state, and performance, so as to report on these and other system events detected. The probe array includes a plurality of coaxial probes connected in parallel. A centrifugal force is applied to the separation bowl.
