What are Suntour Power Rings?

I'm looking at these for an old mountain bike commuter.

Are the power rings Suntour's version of Shimano's Biopace? I did a fast search but didn't find much of anything.

Those look round/circular.

Yes, they're round chainrings (I have them on my commuter). "Power ring" is just marketing because who wants plain old generic chainrings.
