  • System and method for determining at least one characteristic of a transmitting coil
    Patent number: 11397222
    Abstract: A system for determining at least one characteristic of a transmitting coil generating a magnetic field may include a first measurement coil being wound in a first direction, a second measurement coil being wound in a second direction, a voltage measuring device, and at least one processor in communication with the voltage measuring device. The first measurement coil and the second measurement coil may be adjacent to one another. The voltage measuring device may be configured to measure a first voltage of the first measurement coil and a second voltage of the second measurement coil in response to the magnetic field generated by the transmitting coil. The at least one processor may be configured to determine the at least one characteristic of the transmitting coil based on a ratio between the first voltage and the second voltage at a predetermined frequency.
