Abstract: A method for wirelessly coupling respective transducers of an automated motion platform and a sub-surface sensor node through a skin of a limited-access structure for the purpose of wireless power and data transfer. Coordinates of an as-designed position of the transducer of the sensor node in a local coordinate system of the limited-access structure are retrieved from a non-transitory tangible computer-readable storage medium. Then coordinates of a target position on an external surface of the skin of the limited-access structure are estimated. The target position is calculated to be aligned with the as-designed position of the transducer of the sensor node. The motion platform is moved under computer control so that the transducer onboard the motion platform moves toward the target position. Movement ceases when the transducer onboard the motion platform is at the target position. Then wave energy is transferred between the aligned transducers.

Based on determining that the human tissue is present within the near field, the UE determines an amount of radio frequency exposure associated with the human tissue. Based on determining that the amount of radio frequency exposure exceeds a maximum permissible exposure, the UE reduces the amount of radio frequency exposure associated with the human tissue.
