Abstract:
A structural system comprising:an outer housing including an inner active member within the outer housing; a control member for maintaining the inner active member at a predetermined position within the outer housing; an isolation subsystem that connects the outer housing with a surface, wherein the isolation subsystem is softer than the outer housing and substantially limits structural communication from the outer housing to the surface and from the inner active member to the surface; an array of interconnected outer housings, each outer housing of the array of interconnected outer housings including an inner active member; and wherein a control member within each outer housing of the array of interconnected outer housings determines a specific vector force to apply to a respective inner active member for maintaining the respective inner active member at a predetermined position within its respective outer housing based upon a formula as follows: y/u=âˆ’&Sgr;YRy+&Sgr;YHy, wherein y represents a velocity of displacement between the outer housing and the inner active member, u represents a specific force vector, &Sgr;YRy represents a sum of inner active member transfer functions at respective degrees of freedom, and &Sgr;YHy represents a sum of outer housing transfer functions at respective degrees of freedom.
