Small servo motor on each shock that turns the compression valve on the reservoir. The prototypes that were mounted on the sled were a little on the large size, but the engineer I was talking to said they were components they had laying around and used for testing. Functional testing was complete and he said they were working on sourcing some smaller, more compact parts to keep them as small as possible for both weight and durability. The shocks were mounted on a sled so I can't tell you how much more they weighed comparative to a standard shock. My guess would be an additional 1/4lb per shock when it's all said and done plus wiring and button. He said actual product should be available to the public after the 1st of the year. I forgot to ask about the details of how they are powering the system.
