Why would we be interested in the technology from 1980s… oh.
Also, this is Bose of active noise cancellation - very fitting, since this looks like anc for wheels. They did anc for car seats too and sold it to the same buyer:
> As part of the deal, ClearMotion also acquired the technology for Bose Ride, a special "active" car seat for truckers that improves ride quality and reduces occupant fatigue. Bose used what it had learned from developing the active car suspension system to create Bose Ride, but it remains a niche product.

- crazygringo 1y ago> since this looks like anc for wheels I was wondering why the heck Bose got into this. Thanks, that was the missing link -- I never thought of suspensions as noise cancellation but of course they are!
- sfifs 1y agoAt one point, Bose was a few scientists who happened to have a consumer tech company.
- bunnie 1y agoI got a tour of Prof. Bose's factory as a student while taking his course on acoustics. Active suspension is basically a speaker voice coil but scaled up and pushing a car wheel instead of a cone. A lot of the physics and perhaps more critically, the manufacturing processes, were shared between speakers and suspension as they implemented it. I actually got to sit in the car as it drove over bumps, it was pretty magical. iirc you could flip a switch and set a suspension profile that made it emulate other cars road feel as well. Years later I built a toy model of it using an actual speaker to make a pushbutton switch that could emulate the feel of a broad range of other switches.
