    Abstract: Disclosed is an implantable medical device and methods of using the medical device. The medical device may include a guided surface wave receive structure configured to receive a guided surface wave transmitted by a guided surface waveguide probe. The guided surface wave receive structure in the medical device generates an alternating current signal when the guided surface wave is received. The medical device includes a power circuit that is coupled to the guided surface wave receive structure. The power circuit includes a power storage circuit to store the power signal. The medical device includes a medical circuit that comprises a stimulus circuit, a monitoring circuit, and potentially other components. The stimulus circuit provides a stimulus to a human body. The monitoring circuit measures a characteristic of the human body.

    Abstract: Disclosed are various embodiments for fixing a navigational position using guided surface waves launched from guided surface wave waveguide probes at various ground stations. A navigation unit may fix its position by determining the travel time of guided surface waves from the ground stations to the navigation unit. In another embodiment, the navigation unit may also fix its position by determining the change in intensity of the guided surface waves after travelling from the ground stations to the navigation unit. In other embodiments, the navigation unit may also fix its position by determining the difference in phases of phase-locked guided surface waves as they travel from the ground stations to the navigation unit.
