Abstract
An apparatus includes a hermetically sealed housing formed of conductive material. The hermetically sealed housing contains a circuit that includes a power supply and a power using element. The power supply has a power receiving element within the hermetically sealed housing for receiving electromagnetic radiation having a frequency low enough to penetrate through the conductive material. The power supply is connected to provide electrical energy derived from the electromagnetic radiation for powering the power using element.
Claims33
