CASE maintains a stable chamber by detecting an impending occlusion break, and
reducing the vacuum before occlusion surge can occur. When the occlusion is
detected, the System waits long enough to allow the particle to be firmly grasped,
and then reduces the vacuum to a lower level in order to allow the occlusion to be
safely cleared. When the occlusion is fully cleared, the vacuum returns to the
previous vacuum level.
