To mitigate Electromagnetic Fields (EMF) human exposure from base stations, international standards bodies define EMF emission requirements that can be translated into limits on the "actual" Equivalent Isotropic Radiated Power (EIRP), i.e., averaged

When performing a radio frequency (RF) electromagnetic field (EMF) exposure assessment of a base station as described in the international standard IEC 62232, the actual maximum approach provides an assessment method based on the actual exposure leve

The development of a capnometry wristband is of great interest for monitoring patients at home. We consider a new architecture in which a non-dispersive infrared (NDIR) optical measurement is located close to the skin surface and is combined with an
