Abstract
A wireless data and energy transfer system includes transmitting and receiving devices. The transmitting device includes a transmitting device controller and an RF transceiver, a proximity sensor, and a memory module each connected to the transmitting device controller, and a transmitting antenna connected to the RF transceiver and having a diagonal dimension, D. The receiving device includes a receiving device controller, an RF memory module connected to the receiving device controller, and a memory antenna connected to the RF memory module. The transmitting device controller is configured to simultaneously transfer data from the memory module to the RF memory module and RF energy from the transmitting antenna to the memory antenna when the proximity sensor senses the receiving device within a distance less than or equal to the distance D from the transmitting device.
