High voltage and low voltage switch mode circuits and methods serve to recover the charge stored on electro-luminescent lamp panels that would otherwise be dissipated during the discharge cycle of a drive circuit. Air is circulated from the wood chips processing chamber by way of a dedusting cyclone into said one or more nozzle chambers. This prevents each capacitor from being charged at a voltage exceeding a withstand voltage. The source of the second NMOS is coupled to a second voltage. After all the frames have been analyzed and the timestamps adjusted, the frames are merged together and put into chronological order to simulate a single capture of data encompassing all of the points where the data was collected. The caster arrangement allows for a small, heavy cabinet to be situated on the panels of the access floor without applying concentrated or ultimate loads on the panels that may exceed the design characteristics of the panel and access floor.
