They correspond to certain skills that modify either your powers or your BO powers. Consult your skill menu or open the power menu (P by default) and read the descriptions of each power to see what skill modifies them.
Example: Halon System sci console gives a bonus to the Emitter system, which affects Polarize Hull and Hazard Emitters.
