In 2015, Steinway & Sons launched a line of Grand pianos that, with the help of an iPad, allowed owners to tap into an archive of performances by some of the world’s top players, and have the piano play them back. Now the iconic maker has introduced the next generation of this piano – the Spirio | r – which can record a musician’s own live performance and play it back, while also allowing for tweaking and sharing through a companion app.
 How to Fast-Charge Your SupercapacitorSponsored by Maxim Integrated Supercapacitors (or ultracapacitors) are suited for short charge and discharge cycles. They require high currents for fast charge as well as a high voltage with a high number in series as shown in two usage cases: an automatic pallet shuttle and a fail-safe backup system. In these and many other cases, the fast charge is provided by a flexible, high-efficiency, high-voltage, and high-current charger based on a synchronous, step-down, supercapacitor charger controller. |
