I think the technology is somewhat related to Fluidics, but there are
moving parts (the ball) and the movement of the ball is the thing
sensed, not the pressures or flows directly related to the proximity
of the sensed part.

small distinction, but a true fluidics device would have feedback
based on the alteration of the flow or pressure between the sensor and
the part.

Regardless, the idea is interesting and has potential.
