  • Patent number: 10916143
    Abstract: Provided are a system and method for intersection collision prevention. The intersection collision prevention system may include a collision determination unit configured to calculate a first space between a preceding vehicle running in the same direction as a host vehicle and at least one of a yellow center line and an oncoming vehicle located in the opposite lane with respect to the host vehicle and compare the first space to a predetermined second space to determine a danger of a collision; and a control unit configured to adjust a collision danger warning time point according to a determination result of the collision determination unit.

  • Patent number: 10832578
    Abstract: A system for collision prevention of a host vehicle includes a camera sensor and/or a radar sensor mounted to the host vehicle and having a field of view outside of the host vehicle. A controller communicatively connected to the camera or radar sensor is configured to determine a first lateral distance between a preceding vehicle running in a same direction as the host vehicle and one of a roadway center line or an oncoming vehicle located in the opposite lane with respect to the host vehicle. The controller compares the first lateral distance to a second lateral distance to determine a danger of collision, and controls a danger warning device to generating a warning signal according to a result of the comparison. A method for collision prevention is also provided.

  • Patent number: 7537673
    Abstract: Disclosed herein is a plasma processing apparatus, which generates plasma within a vacuum chamber to process semiconductor substrates using the plasma. The apparatus comprises a substrate mounting table, an outer lifting bar, and a baffle. The outer lifting bar comprises a driving shaft, and a substrate supporting member coupled perpendicular to an upper end of the driving shaft. The baffle comprises a baffle plate coupled to the upper end of the driving shaft, and a shielding portion coupled to a lower surface of the baffle plate. The substrate supporting member is a foldable substrate supporting member. The baffle and the substrate supporting member are driven up and down at the same time by the driving shaft. As a result, it is possible to protect the substrate supporting member from plasma, and to prevent interference between the baffle and the outer lifting bar during operation of the plasma processing apparatus.
