ClearMotion founder here! Wanted to share some insights that might answer questions from other commenters and clarify what we've developed. The ClearMotion1 system is a major leap above all tech currently on the market, with transmitted vibration reduced about 80% versus top market technologies. Here's a video comparing it on production NIO cars against luxury vehicles using semi-active (or slow active) systems others mentioned - sort of like comparing a microcontroller to a NVIDIA H100. http://bit.ly/44TDtgl This matters especially for autonomous vehicles, where the whole point is to give people back time, and preventing motion sickness while working/reading is essential. Our tech stack: - Electro-hydraulic actuators that both push/pull actuate and dampen within a few milliseconds, using electric motors (not solenoid valves or special fluids). …

Impressive, but is it as stylish and smooth as the 1978 Royal Deluxe II? https://www.youtube.com/watch?v=vnOwHu_wchg

Didn't GM have a camera/software combo that would relax the MR dampener before bumps at one time? It didn't have active movement - just a regular shock but with fine control over fluid movement. I think you're saying you have a pump that moves hydraulic fluid in anticipation of a road defect/speedbump, and does it per-wheel and proportional to the correction needed. Which is fascinating. With regards to pre-crash posture, I'm not sure if this is to move the occupants into a more advantageous position for airbag deployment or to get more crash structure involved for a dissimilar vehicle crash (sedan vs. truck). Can you talk more about it? Is there going to be IIHS/Euro NCAP/C-NCAP testing?

Hello. How does this suspension handle severely neglected roads with large potholes or even off-road type with say 40-50mph? And I mean regularly, for years?

any work with US automakers planned? Are there issues working with EU / China due to current political realities?

> "Infinite preview" control using crowdsourced road data with <3cm localization precision Let me guess, all those demos are with carefully mapped bumps.

The article says that Bose gave up and sold the rights because: "Sadly it was totally impractical for mass production in 2004" What does that mean? Was it too complex or costly to make it back then? Did that change now with your developments? Better tech is nice but if it's to expensive or hard to mass produce then it could end up the same way as with Bose.

If you are looking for future ideas: While most vehicles used in ag are going to be combustion based for a long while, if you could apply the shock mitigation to a just a chair in spray rig ( https://hayandforage.com/images/29-Thome_MR_38-WEB.7650.png ) or fertilizer buggy, a lot of spines could be saved. These vehicles are lighter and generally run faster than tractors, and applicators who run them for decades tend to be forced to retire in pretty bad shape.
