Each wheel on your car gets a 2 oz. air pump permanently installed, and a strong magnet is mounted so that the pump passes by on each rotation. A tiny bellows inside the pump gets compressed as it passes the magnet. If the air pressure inside the tire is low (or high,) the air in the bellows gets pumped into the tire, else it gets vented.
Each rotation can only add about .02 cc of compressed air, but that's plenty to handle slow air leaks, and maintain air pressure. Since there's no contact required, there are no expensive rotating seals as with hummers.
Yes... it IS patented. The patent owner is working with all the auto companies and with after-market vendors. As I understand it, it isn't adjustable; the pump pressure is fixed at design time.
.02cc is a tiny amount of air, but, at 60 MPH, it's about a quart of compressed air volume per hour.
