Active isolation elements

high-force piezoelectric actuators that receive signal
from a high-voltage amplifier with an output of up to 800 VDC

Passive isolation element

single stiff elastomer (no compressed air supply required)

Vibration sensor elements

downward facing geophone type inertial sensors
that measure floor vibration below the isolator
and deliver voltage proportional to the velocity of vibration motion

Active feedback control loop

Floor vibration is measured, processed
and attenuated below the spring
supporting the isolated surface
