Abstract
A contactless power supply and system is provided that comprises an inductive coil disposed within a seatback tray of a mobile platform, e.g. a commercial aircraft, and a receptor disposed within a computing device, wherein the computing device is placed on the seatback tray and the inductive coil is energized, thereby providing electrical current to power the computing device. The contactless power supply further comprises a shielding member that is installed in the computing device to protect components of the personal computer from any detrimental effects of magnetic fields produced by the inductive coil.
