  • Publication number: 20250116568
    Abstract: A sensor cleaning system includes an air tank connected to a compressor through a first connector and to be filled with high-pressure air by the compressor. The system also has a roof module and a rear bumper module. The system includes an air flow path connected to the air tank and branched by a second connector to a first branched air flow path and a second branched air flow path. The first branched air flow path is connected through a third connector to the roof module and the second branched air flow path is connected through a fourth connector to the rear bumper module. The system also includes a pressure sensor installed on each of the air tank, the roof module, and the rear bumper module to detect pressures thereof. The system also includes a controller configured to determine connection states of the first connector, the second connector, the third connector, and the fourth connector through a difference in pressures.

  • Patent number: 8404408
    Abstract: A mask for sequential lateral solidification (SLS) which is capable of preventing an overlapping region and a diagonal stain based on a crystallization pattern of an active layer. The mask for SLS, which moves in a first direction and selectively transmits a laser beam emitted by a laser emitting device, includes slits which are formed such that the width of a slit in the first direction is smaller than the width of the slit in a second direction, which is perpendicular to the first direction. Each of the slits is tilted by a predetermined angle with respect to the first direction.
