A terrestrially deployed flexible antenna is disclosed. The pixel structure includes a data line, a scan line, at least one active device, a pixel electrode, and a metal line. The electronic control unit determines that the electrical heating catalyzer has a failure when a variation width of the insulation resistance is smaller than or equal to a set value in a historical variation in the insulation resistance measured by the measuring device. Consequently, even in a low-temperature environment, the heating operation keeps ink in a desired condition suitable for printing. The sealing element has a first radial region with a first stiffness or rigidity and a second radial region with a second stiffness or rigidity, wherein the first stiffness and the second stiffness are different from one another, and the sealing element is configured as segmented in the peripheral direction of the turbomachine. , a complementary punctured pair convolutional code.
