National Institute of Standards and Technology (NIST) researchers have developed a dc and ac Josephson voltage standard system that produces output voltages of up to 0.25V, making possible far more precise measurements and comparisons with existing power-detection-based ac voltage standards. Currently, the team is striving to achieve output voltages of 0.5 to 1V, which would reduce uncertainties in ac voltage measurements by three to four orders of magnitude, similar to today's dc volt standards that are based on quantum effects.
The transformative nature of designing and making things was the overarching, common theme at separate conferences held in Boston by two giants in the PLM space: Autodesk, with its Accelerate 2015, and Siemens’s Industry Analyst Conference 2015.
