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.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
