public class FilterLatchModule
extends MobileItemModule

This is a model for a latch. A latch is what holds a filter in the trucks of the autochanger. There is 2 latches : one on each side of the filter. The state of the latches are monitoring by digital sensors : one sensor to know if a filter is in the latch or not and 2 status sensors to know if the latch is locked or unlocked. If the 2 status sensors are inconsistent, the latch is in error.
