  • TERMINAL AND ELECTRODE DEFECT DETECTION METHOD
    Publication number: 20240354932
    Abstract: A terminal can include a display and a processor configured to generate a reconstructed image based on a plurality of X-ray images of a battery, and rotate the reconstructed image by a predetermined angle to generate a tilting image. Also, the processor can generate an electrode detection image based on the tilting image, the electrode detection image including a positive electrode of the battery and a negative electrode of the battery in which the positive electrode and the negative electrode are separated from each other, and detect whether the battery is defective based on the electrode detection image.

  • Coil structure for inductive and resonant wireless charging transmitter and integral control method for the same
    Patent number: 10461564
    Abstract: Provided is a wireless power transmitter including a first coil disposed to transmit wireless power, a second coil disposed outside of the first coil to transmit wireless power, and a controller configured to determine whether to operate the wireless power transmitter in a magnetic induction mode or a magnetic resonance mode, control the first coil to operate in the magnetic induction mode and prevent the second coil from operating in the magnetic induction mode in response to the determination to operate the wireless power transmitter in the magnetic induction mode, and control the first coil and the second coil to operate integrally in the magnetic resonance mode in response to the determination to operate the wireless power transmitter in the magnetic resonance mode.
