The DSPH Series of 12- to 16-bit, 25 VA, reference-powered digital-to-synchro converters require a (plusMinus)5V dc input power and have internal transformer-isolated outputs even at 60 Hz. The series will accept up to 16-bit natural binary input and convert it to 90V 3-wire synchro signal from 60 to 400 Hz with an accuracy of up to (plusMinus)2 minutes of arc. The output is short-circuit-proof and current-limited with transient protection and thermal cutoff. A kick circuit frees the torque receiver rotor to prevent hangups. The unit is packaged in a 5.09 x 7.4 x 2.60-inch bulkhead-mounting metal case.

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.
