Self-protecting signs
Storms often beat the heck out of billboards. After a good storm, outdoor
advertising companies must send out crews to repair damaged installations. The
cost of such repairs gets passed on to advertisers and, finally, to the users of
the advertised products.
To prevent such damage, a controller mounted on the billboard monitors sensors to determine wind direction and intensity. When winds reach dangerous levels, the billboard "weathervanes," rotating to minimize its exposure to the wind. As wind intensity decreases, the undamaged billboard rotates back to its home, or "display", position.

Self-aligning gearhead
Until now, precision gearheads for servo and stepper motors required precision installation. No more.
A clamp-on pinion gear, pre-installed in the rear housing of all ServoMount™ gearheads, ensures fast and error-free installation. The user simply slides the motor shaft into the pinion, then tightens four bolts and a set screw.
Available in standard ratios from 3:1 to 100:1, with torques to 20,000 lb-inches, ServoMount gearheads include planetary and right-angle planetary configurations.
