It's not clear. The article says they used "Small acceleration sensors" to detect whatever it is they detected. I assume those are something like Robert Forward's mass detectors, but I'm guessing. Then they attribute their unexpectedly high readings to gravitomagnetism. It's a bit conjectural at this point. But if they've really detected something, it certainly requires an explanation.

I agree.

I'm not sure how Bob Forward's Mass Detector worked but I thought he was looking for gravitational waves and never actually found them.

These guys must be using some sort of mass detector that shows a deflection from the vertical in the presence of mass. And that deflection changes when the superconducting ring is accelerated. I'm just guessing but that's what it sounds like to me.
