>>35185209They is a type of defibrillator meant to be used by the general public in health emergencies. The idea is that you'd have these in e.g. airports and if someone has a heart attack, the machine talks you throught how to use it - which is mostly connecting the electrodes and letting it do the rest of the work. This foundation is about spreading both the defibrillators themselves as well as public awareness of them.
