First Claim
Patent Images
1. An adaptive support system, comprising:
- a payload;
a coarse suspension device coupled to the payload and adapted to maintain a position of the payload within a first range of distance;
a fine suspension device coupled to the payload, the fine suspension device being adaptively programmed via a control signal to dampen movement of the payload within the first range of distance; and
a weight information device adapted to provide weight information relating to the payload, wherein a damper resistance of the fine suspension device is adjusted in response to the weight information.

Abstract
A method and apparatus for an adaptive, multi-axis suspension support system providing both coarse and fine suspension to a payload. Coarse suspension control is provided to maintain the payload within a coarse range of position. Fine suspension control is provided by monitoring and analyzing vibration characteristics in both time and frequency domains to determine the required amount of damper resistance to be exerted by a magnetorheological (MR) device.
