A display panel of a liquid crystal display device includes a first substrate including a display area having a plurality of pixel portions, and a peripheral area surrounding the display area. The electronic circuit comprises: a first inductive partner element for canceling out said second resonant frequency, said partner element having a quality coefficient QI having a first value in a predetermined frequency band and a second value outside said frequency band; a second capacitive partner element for adjusting tuning of said resonator to said first frequency. The retainer body has a generally arcuate shape that defines an arc between the opposite ends thereof. Data is collected, recorded, and analyzed to enable changes to be made to the ground travel system components in real time automatically by intelligent software or manually by a system operator or at a later time to ensure optimum operation of the system.
