  • Automatically-aligning magnetic field system
    Patent number: 12272967
    Abstract: A wireless power transfer system includes a wireless power transfer device. The wireless power transfer device includes a first transmitting coil oriented along a first axis; a second transmitting coil on the first transmitting coil and oriented along a second axis different from the first axis; and a nonmagnetic material magnetically decoupling the first transmitting coil from the second transmitting coil in an area of overlap between the first and second transmitting coils.
    Type: Grant
    Filed: March 7, 2023
    Date of Patent: April 8, 2025
    Assignee: The Alfred E. Mann Foundation for Scientific Research
    Inventors: Leslie G. Farkas, Brian R. Dearden, Justin Cheng-Tsu Loo
  • AUTOMATICALLY-ALIGNING MAGNETIC FIELD SYSTEM
    Publication number: 20240204582
    Abstract: A wireless power transfer device includes a first transmitting coil oriented along a first axis; a second transmitting coil on the first transmitting coil and oriented along a second axis different from the first axis; a nonmagnetic material magnetically decoupling the first transmitting coil from the second transmitting coil in an area of overlap between the first and second transmitting coils; and a driver configured to separately provide first and second currents to the first and second transmitting coils, respectively, to generate a magnetic field.
