  • Multi-device charging using floating transmitter coil
    Patent number: 11831188
    Abstract: A cart to store a plurality of mobile computing devices includes a plurality of slots defined by opposed plates. Each of the slots is configured to accept a corresponding mobile computing device. A first slot is defined by first and second plates, and a second slot is defined by the second plate and a third plate. The second plate includes a first transmit coil for wirelessly transmitting power to a first receive coil in a first mobile computing device within the first slot, and to a second receive coil in a second mobile computing device within the second slot.
