I thought you might like it. The metering is via the backside of a D-shaped profile that draws in fuel into the airstream. And it has a slide valve instead of a butterfly, what does that do to pumping loses?
It reminds me of the notorious Fish carburetor.

History
From 1947 to 1959 the Fish Carburetor Company of Daytona Beach, Florida manufactured over 125,000 high-mileage carburetors. The Fish carburetor averaged 20 percent better gas mileage and 30% more horsepower.
The Fish Carburetor was originally invented by John Robert Fish in America in the early Thirties. The carb works on pressure differential – not air speed, which means that it is almost instantly self adjusting & self compensating so any change in weather or altitude requires no adjustments or modifications as with conventional carbs. Hence all round suitability for cars, boats, aircraft, mountain or pressure charging use.
Instead of the usual one main fuel discharge point within the carburetor, the “Fish” has from SIX to TEN leading to vastly superior atomization and therefore much improved vaporization...

Fish Carburetors – Ross Carburetors
Similar performance claimed, and altitude compensation. Six to ten discharge point is one difference.
They call it smart but it isn't an Internet of Things play.
