lesser number of springs with varying polar orientations may be employed for discrete definitions while retaining the benefits of the invention the springs may be connected between the nodes and the struts in any suitable manner allowing the spring to maintain the aforementioned functions as illustrated in fig8 the inner end of the spring 50 of the connector module 51 may be retained in a counterbore 53 in the node 52 the outer end of the spring is connected with telescoping tubes 55 of a strut 54 however other mechanical adhesive or otherwise connective means may also be employed for the connections the struts function as a spacing member between the respective nodes and springs as illustrated the struts are tubular and coaxially connected with the springs however the struts may provide for relative translation and articulation actuated or accommodated with non coaxial alignment therebetween or with respect to the springs as illustrated the struts are tubular having a longitudinal axis coaxial with the springs solid and non cylindrical components may also be used as the connecting structure between the node sites in the illustrated cylindrical form or with interior passages defined in the components various control actuating and utility functions may be incorporated within the system for ancillary purposes or for effecting movement of the node sites for instance as shown in fig1 a rotary or linear actuator 80 may.
