How is it different though hiding your thrusters behind a bulkhead versus hiding your thrusters behind a hull plate? Why does one hide it and the other only alter its emissions? Concealed even says it has exhaust ports. Adjustable has no exhaust ports. So, wouldn't it make more sense for Concealed to alter the emissions and Adjustable to block/hide them based on how they are described? If I put a light behind a steel wall, I cannot see the light. If I put a vent in that same wall, I can see the emissions from the light, but it is shining in a different pattern than if the wall isn't there. So, Concealed seems more to Me like altering emissions and Adjustable seems more like blocking, based on how they are described as working.Concealed is meant to be hidden.
Adjustable changes the signature
Variable can either mask the signature (edit: hide) or change the signature
