Heard of a Part Throttle Wastegate?

I read about a PTO wastegate. It is the same as a normal one but also opens up at vacum and part throttle... so the turbo doesnt spoil up when not needed.

The acutator had two springs in it to get this to work on vac and on the max boost pressure set . Some guy called Stanely Updike invented it.

Any clues if they make this?
Any disagreement on not having the wastgeate open at idle/vac?
I guess an electronic boost controller could do this?
