1. An active support system, comprising:
- at least one forward looking sensor for generating output signals;
a support device for supporting a passenger;
a controller, coupled to said support device and said at least one forward looking sensor, wherein said controller adjusts forces in said support device in response to said output signals generated by said at least one forward looking sensor; and
a feedback unit, coupled to said controller, wherein said controller further controls said support device in response to control signals generated from said feedback unit, andwherein the at least one forward looking sensor is a wave sensor.

Abstract
An active suspension system is used to control the motion of a passenger seat in a high speed watercraft. A forward looking wave sensor is used in connection with a feed-forward wave impact shock predictor to determine characteristics of impending dynamic forces applied via the impact of the watercraft on waves. Information concerning the impending dynamic forces is used by a passenger seat suspension and control system to attenuate the shock effects on passengers, where such effects are characterized by large-amplitude, short-duration accelerations recurring at a low frequency and/or irregularly.
