Qi wireless charging power transfer system explained

This is an interesting article about how mobile phones and other devices use the wireless charging system called Qi. New chips developed allow up to 50 W of power transfer and have safety circuits to prevent overheating foreign objects that might come between the energy source and the load.


Processor power efficiency, beyond Moores Law

This article focuses on improving processor power efficiency by a process of heterogeneous multicore design that switches off transistors that are not being used, and assigining individual specialised cores of a multicore processor to work at specific kinds of tasks so the unneeded functions at any specific time can be switched off so they aren’t using power.
