Intensity grid
The intensity grid was a component found in the lab aboard Deep Space 9. 

When a harsh noise overwhelmed the lab aboard the station in 2369, Chief Miles O'Brien speculated to Lieutenant Jadzia Dax, who reported the malfunction, that the source might be the intensity grid, after it was confirmed not to be the EPS converter, Dax explained she already had checked it, and said that it was "fine".
