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.
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.
The Commonwealth Treasury (Treasury) is undertaking this assessment and public consultation on behalf of the Commonwealth, states and territories. This Consultation Regulation Impact Statement (RIS) provides an overview of the current product safety system, explains identified problems and outlines some potential reform options for feedback, including options for a GSP.

Measuring human exposure to 5G:
“IEC TC 106 is playing a key role with the recent publication of a new IEC Technical Report on evaluating human exposure to radio frequency fields in the vicinity of base stations…
IEC 62232 provides methods for determining the radio-frequency field strength near radio-communication base stations with the intention of evaluating human exposure. It takes into account the mmWave frequencies to be used for 5G networks.”
The new EESS website now stands alone to support regulatory activities across multiple states. The safety of household electrical equipment in Queensland, Victoria, Western Australia and Tasmania is regulated using the Electrical Equipment Safety System (EESS), which now has a new online presence at: http://www.EESS.gov.au.
EESS.gov.au removes functions previously found on the Electrical Regulatory Authorities Council (ERAC) website and presents them with enhanced and improved layout and structure, based on feedback from industry.
TGA is proposing to treat software as a medical device in its own right. Presently it’s only regulated as part of another medical device used to treat patients if it could cause harm to patients. The new reforms would treat the software as a medical device directly if it’s used by medical practitioners to diagnose patient conditions (different levels for critical outcomes diagnosis or just screening). The new proposed regulations are based on
International Medical Devices Regulators Forum (IMDRF) guidelines.

Communications Alliance has published two draft standards for public comment on their web site, which now incorporate the principles of the new hazards-based standard: AS/NZS 62368.1:2018 (IEC 62368-1 2nd ed [MOD]). There is also an explanatory background paper. Public commenting closes on 24 May 2019. The standards are:
DR AS/CA S008:2019 Requirements for customer cabling products, and
DR AS/CA S009:2019 Installation requirements for customer cabling (Wiring rules)
Background Paper: DR S008 & DR S009 public comment background paper
