Since most contaminants (e.g., metal, glass, bone) are denser than food, they absorb more energy and therefore they show up ...

Researchers repurposed an experiment originally intended to detect gravity, which involved a floating magnet in a ...

The operating area of a coil pair is limited by the existence of a magnetic null in its coupling profile. For circular charging pads, employing a symmetrical Archimedean spiral, a magnetic null occurs ...
