Its on the shocks. WTF is it?

(General description [generic])

"Progressive damping provides deceleration with gradually increasing shock force. The initial minimal resistance at impact protects delicate loads and machinery from damage. Progressive damping shock absorbers also have built-in self-compensation so they can operate over a wide range of weights and velocities. This type of damping provides smooth deceleration in applications where energy conditions may change...

NSX Blurb about the Acura Progressive Valve design:

The shock absorbers are nitrogen-filled and feature a unique progressive valve design. The progressive opening of this valve produces a more favorable damping profile, and more precise damping control, than a conventional valve system in which the fluid control orifices are either fully opened or closed.

Comments:

Most dampers have a set of orifices/valves for rebound and compression. Some of the newer designs will use an inertial load to “dynamically” change the valve characteristics.

As to the "exact" technology that Acura uses in their shocks, perhaps someone will dig up a patent or other spec for you...

If you find the patent, I’d love to see it…
