From what I have read, Laser Guidance Dynamic compensation...

From what I have read, Laser Guidance Dynamic compensation systems historically have involved "painting" a target with a laser generated dot, and then the object's movement towards the dot is guided in by dynamically making minor course adjustments to keep the object heading along the correct vector. The nature of the object often doesn't need sub millimeter accuracy.

This is not what I understand the FBR DST to do.

My understanding (and I admit I have not taken time to read the detail of the patent) is that the FBR DST uses a laser directed at a fixed target to continually determine the sub millimeter position of an object (in this case a brick) and move that object into a known pre determined position (that is not the target of the laser) while applying compensation for any changes in the objects path through the environment.
