Improved approaches to access information concerning media asset groups are disclosed. The two sorting systems have the same number of sorting outlets, the two systems being superposed so that the sorting outlets of the first sorting system are superposed on respective ones of the sorting outlets of the second sorting system. While the binder may be utilized with unconsolidated nonwoven fabric webs made by a variety of methods, the binder is particularly useful for application to webs made via the latex bonded airlaid or multibonded airlaid methods. Further, in an aspect, the method involves receiving an input for a threshold value through the GUI, and comparing the threshold value to a value being monitored. The time taken for the capacitor to recharge when the optocoupler is re-opened is used to determine if there has been any threshold decay in the interface.
