List of events during manipulated printing unit demonstrator operation
----------------------------------------------------------------------

00:00 - 02:55 (feature instances 1 - 100):training data acquisition,
	demonstrator in normal condition
02:55 - 03:45 (feature set instances 101 - 128): normal operation 
	without incidents or manipulations, demonstrator in normal 
	condition
03:45 - 03:55 (feature set instances 129 - 135): activation of analogue 
	low-pass signal filter to treat the solid-bourne sound signal, 
	demonstrator in normal condition
03:55 - 04:33 (feature set instances 136 - 155): gradual attenuation of 
	the solid-bourne sound signal by decreasing the low-pass 
	filter's cutoff frequency continuously, demonstrator in normal 
	condition
04:33 - 06:36 (feature set instances 156 - 224): normal operation at 
	smallest possible cutoff frequency of the solid-bourne sound 
	low-pass filter, demonstrator in normal condition
06:36 - 07:08 (feature set instances 225 - 242): deactivation of the 
	analogue low-pass filter, demonstrator in normal condition
07:08 - 08:33 (feature set instances 243 - 290): uneven turning of the 
	print cylinder (unintended), demonstrator in abnormal condition
08:33 - 10:31 (feature set instances 291 - 357): contact pressure  
	decreased until no contact between both cylinders, demonstrator in abnormal condition
