Although standard vibration-isolation techniques use passive damping to reduce disturbances transmitted through the floor — vibrations from footsteps, passing trucks and heavy equipment in the ...

SEM-Base VI will allow more laboratories and facilities to obtain the level of floor vibration needed to fulfill the specifications of the tool manufacturer. SEM-Base VI utilizes a special ...

STACIS cancels vibration in real-time by continuously measuring floor activity, then expanding and contracting piezoelectric actuators to filter out floor motion. The all-new STACIS 4 is built upon ...

three or four Minus K ® SM-1 negative-stiffness vibration isolators, a large platform, outriggers that link the isolators to the platform, ballast weights, and isolator floor and jack screw plates ...
