Gerwah zero-backlash couplings are available in safety, metal bellows, and servo insert designs to provide servo-quality machine and drive protection for industrial machine applications. All lines are available with multiple clamping styles. Safety couplings feature a pre-stressed Bellville spring to disengage highly dynamic servomotors within 2 to 4 msec. Metal bellows couplings feature high torsional stiffness and low inertia. Electrically insulated servo insert couplings are available to increase dampening without deformation.

Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
