A vacuum cleaner includes a suction body to draw in dust along with air from a surface to be cleaned; a cleaner body having a suction motor; and a cyclone dust collecting apparatus detachably coupled in the cleaner body. The cyclone dust collecting apparatus includes a cyclone unit to form a first current turning in a first direction to separate the dust and the air drawn therein from each other and having a dust outlet to discharge the dust separated from the air; and a dust collecting unit to collect the dust discharged from the dust outlet. The dust outlet has a side formed adjacent to an inner wall of the dust collecting unit to form a second current turning in a second direction opposite to the first direction to allow the dust discharged through the dust outlet to whirl along the inner wall of the dust collecting unit.

A robotic surgical system includes a master manipulator, slave robotic units having a surgical instrument for performing a Minimal Invasive Surgery (MIS), and a control system for electrically associating the master manipulator with the slave robotic units. The slave robotic unit includes the driving mechanisms which are more compact than those of the conventional MIS system. In use, the existing surgical instruments used in the conventional MIS procedure can be applied to the slave robotic unit. Moreover, by using the pivotal mechanism of the driving mechanisms, a pivot point of the surgical instrument is allowed to be shifted with respect to an incision of a patient. So, the patient's tissues surrounding the surgical instrument are not excessively affected by the surgical instrument during the procedure.

The hand-held cleaner includes a body, and a cyclone dust collecting apparatus detachably mounted in the body. The cyclone dust collecting apparatus includes a pre-motor filter unit having a filter grill and a filter member, a dust collecting bin having one end to which the pre-motor filter unit is coupled and the other end opposite to the one end in which an cyclone inlet is formed, and a cyclone bin disposed in the dust collecting bin and having a spiral flow path-guide member integrally formed therein. A moving path of air drawn into the cyclone inlet is maintained in the same direction until the air is discharged through the pre-motor filter unit via the cyclone bin.

Provided are a method and apparatus for processing an image. The method includes receiving a first luminance image of an image including airlight, which is a type of light that occurs in a foggy environment, and generating an airtight map based on a ratio between an average luminance of the first luminance image, and a standard deviation; and removing the airtight by subtracting the airtight map from the first luminance image and outputting a second luminance image. According to the present invention, airlight components may be effectively removed.

Nonvolatile memory cells having a split gate structure and methods of fabricating the same are provided. The nonvolatile memory cells include active regions defined at a predetermined region of a semiconductor substrate. A portion of each of the active regions is etched to form a cell trench region. Insulated floating gates are disposed on a pair of sidewalls parallel with the direction that crosses the active region. A source region is disposed at a bottom surface of the cell trench region. A gap region between the floating gates is filled with a common source line electrically connected to the source region. The common source line is extended along the direction that crosses the active regions. The active regions, which are adjacent to the floating gates, are covered with word lines parallel with the common source line. Drain regions are disposed in the active regions adjacent to the word lines. The drain regions are electrically connected to bit lines that cross over the word lines.
