The electromagnetic energy transfer device includes a first resonator structure receiving energy from an external power supply. The first resonator structure has a first Q-factor. A second resonator structure is positioned distal from the first resonator structure, and supplies useful working power to an external load. The second resonator structure has a second Q-factor. The distance between the two resonators can be larger than the characteristic size of each resonator. Non-radiative energy transfer between the first resonator structure and the second resonator structure is mediated through coupling of their resonant-field evanescent tails.

Sender communications for wireless power transfer
A signal generator generates an electrical signal that is sent to an amplifier, which increases the power of the signal using power from a power source. The amplified signal is fed to a sender transducer to generate ultrasonic waves that can be focused and sent to a receiver. The receiver transducer converts the ultrasonic waves back into electrical energy and stores it in an energy storage device, such as a battery, or uses the electrical energy to power a device. In this way, a device can be remotely charged or powered without having to be tethered to an electrical outlet.

System to automatically recharge vehicles with batteries
A plug-in hybrid electric vehicle (PHEV) is an automobile which can use either electricity or gasoline. With high gasoline prices, electricity is becoming a promising alternative to power next generation automobiles. One advantage of the PHEV and the BEV (battery electric vehicle) is that charging can be done at home. However, the small battery capacity of PHEV's may require recharging the batteries almost daily. It would be convenient for an owner of a car with batteries to not have to plug in the battery each and every day that charging is required. Our invention is a system that plugs the power automatically into the vehicle with minimal human intervention using an automated docking system. The system is composed of a robotic manipulator with a camera and a processing unit. The system uses the camera and vision processing to identify the vehicle's position, and consequently, the location of the vehicle's charging receptacle. The robotic manipulator then directs the charging cord's plug into the receptacle of the vehicle. Once charging is complete, the robotic manipulator removes the plug from the vehicle.
