I still don't quite understand the "no moving parts" claim from the
manufacturers.

So what is moving? Light? That does not qualify as a part, IMHO.

I said I *don't understand* that aspect of the design at this point, so I
have no basis to confirm or dispute that there are no moving parts.

The patent app that I referenced is quite vague about how "...the angular
velocity applied to the fiber optic coil about the axis thereof..." would
result in any phase shift if the length of the light path is unchanged by
virtue of the light source and coil being fixed in relation to one another
("solid state"). OTOH, if the device works based on a change in position
between the light source and the coil due to an angular velocity, then it
has moving parts, and the light interference pattern simply measures the
amount of movement.

So, if you *do* understand how it works without moving parts, I would
appreciate a clearer explanation.
