Single module two-speed synchro to digital converters feature 16-bit resolution and ±0.005 degrees of accuracy hs. The devices convert two-speed synchro or resolver inputs of 11.8 or 26V or 90V 400 Hz or 90V 60Hz into 16-bit parallel binary outputs representing angle. Speed ratios of 1 x 10, 16, 18, 32, 36, 64, or 128 are available. The converters can track rates up to 1,000 degrees/sec and also have a dc velocity output and built-in test digital indication of correct operation.

Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
