Free-Flex(reg) Pivot frictionless, precision cross-spring bearing is for use wherever limited angular rotation bearings are required for angular travel up to ±30 degrees. The bearings require no lubrication or maintenance, are dirt insensitive, and eliminate the inaccuracies of friction, stiction, wear, radical clearances, and backlash. The pivot has a high radial and axial stiffness to maintain repeatability to ±0.000001 inch in one plane of motion, with low hysteresis, center shift, and thermal drift.

The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
