How does Nikon 1 do Phase Detect Autofocus?

Are there any technical details on how Nikon is doing this?

Does the sensor sacrifice some pixels for phase detection sensors? Are they able to do this with normal pixels on a sensor.

Patents?

I am really curious how this was done and if it is likely to stay an Nikon only feature.
