Engineers don't decide the technical details of their implementation; they don't decide what to implement.
I don't know what kind of engineering you do, but 80% of my time as a professional engineer is spent deciding the technical details of implementations.
McDonalds in France (and in the UK and many other countries) do not allow still cameras, video cameras or other recording equipment to be operated inside their restaurants without explicit permission from the managers.
It is true that he brought a camera-type device in with him, but it was a Physician Sanctioned vision assistance system (and he even had appropriate documentation!). It is not like he brought a point-and-shoot in and started taking silly snapshots of people without their consent. This is a device that he needs to enable him to live a normal life.
I bet that very same McDonalds does not allow pets in their establishment, but they would allow a Seeing Eye dog. In my mind, this should be cast in the same light.
The 60 percent ride improvement figure was obtained when a single wheel equipped with the system was mounted on a laboratory testbed that simulates road conditions.
That's not exactly a complete answer, but I would guess the mounted an accelerometer or some other device to measure vibrations and compared that number to a passive system run over the same course. But I am making a bit of a leap there...

You mean like Scientology?
God may be subtle, but he isn't plain mean. -- Albert Einstein
