Any experience with this type of “internal suspension” wheel?

No experience here. But I remember reading the biography of Major Taylor written
by Ritchie. After Taylor's retirement from racing, he tried several different
business ventures. One was marketing a somewhat similar sprung wheel for cars.
It went nowhere, and he died broke.

Extra weight, slack in pivoting joints, probably no reduction in unsprung weight,
etc. I'll be very surprised if it's an improvement.

But I tend to be skeptical of whiz-bang bike inventions.

Indeed. Tensioned spoke bicycle wheels are among the most
formidable strength/weight things humans make. I remember
when a Montgomery Young[1] front race wheel was tested by
some English industrial association to something like 1/2
tons static load[2] without deformation which garnered a lot
of cycle industry press fawning[3].

[2] Your average putz can break any wheel with normal
impact, which is a different test.
[3] Outside of cyclists, no one cares about bicycles or
bicycle wheels.
