Abstract

A mounting system is described having a frame structure and an elastic structure adapted to mount a suspended object with the elastic structure having a critical configuration point close to which its stiffness in a desired direction approaches zero. The mounting system is particular useful for suspending small objects, such as camera lenses actuated by a piezoelectric actuator.
