public class Truck
extends Object

A truck is a mobile part in the autochanger. This is a model for the single-filter-test autochanger truck. It's the mechanical item which holds a filter through a latch and moves the filter from STANDBY position to STANDBACK and back. There is 2 trucks in the autochanger, one on each side of the filter. A truck move along a rail. The position of a truck is given by 2 sensors (hall effect sensor) which are located on the rails. One is at STANDBY position, the other is at STANDBACK position. The trucks are moved by a motor. They are moved together by a motor which synchronizes the motion of both trucks.
