Abstract: Embodiments disclosed herein provide a wireless controller which shows a voice, motion, or an image complying with or not complying with a user's command and controls an external device in accordance with the user's command. According to an embodiment, a wireless controller includes a main body provided in a shape of a flowerpot, and includes a voice recognition unit, a control unit generating a signal for controlling an object to be controlled, which is designated by a voice recognized in the voice recognition unit, in accordance with the voice, and a communication unit outputting the control signal generated in the control unit to the object to be controlled; and an indicator provided at the main body in a shape of at least one of a stem, a leaf, a flower, and a tree, and showing a motion corresponding to the voice recognized in the voice recognition unit.

Abstract: Modules with various functions may be mounted on a robot cleaner, such that the robot cleaner can perform various additional functions other than cleaning while moving. The robot cleaner cleans a floor surface while moving on the floor surface. At the robot cleaner, a module mounting unit on which at least one module capable of performing a function other than cleaning is able to be mounted is disposed.

Abstract: The present invention provides a method for improving the tolerance of a plant to an abiotic stress and a method for promoting growing of a plant, comprising a nucleotide sequence encoding the AtSRP (Arabidopsis thaliana stress related protein) of a plant. The present nucleotide sequence is involved in abiotic stress tolerance such as drought, low-temperature and salt stresses of plants. Therefore, the overexpressing transgenic plants have excellent tolerances to these abiotic stresses, whereby they may be useful as novel functional crops which are affected by climates and environments of the cultivated areas. In addition, where the plants are transformed with the present nucleotide sequence, the growth abilities of the transgenic plants are remarkably enhanced, whereby they may effectively used for cultivating the plants with novel function of rapid growing, and biomass.

Abstract: A brush assembly for a vacuum cleaner includes a brush body having a suction inlet; a main brush which is rotatably coupled to the brush body through the suction inlet to face a surface being cleaned; and a secondary brush which is rotatably mounted on the brush body to rotate between at least two positions including a first position, in which the secondary brush contacts the surface being cleaned, and a second position, in which the secondary brush does not contact the surface being cleaned.

Abstract: A suction brush for a vacuum cleaner is provided. The suction brush a vacuum cleaner includes a brush main body connected to a cleaner main body and having a dust suction port provided on a bottom surface of the brush main body, first and second wheels rotatably engaged with both sides of the brush main body, and at least one hair removing unit, arranged in front of the suction port of the brush main body, for receiving rotation drive forces from the first and second wheels and raking up hair existing on a surface to be cleaned toward the dust suction port.

Abstract: An upright vacuum cleaner has a cleaner body; a suction port assembly hinged to the cleaner body with a drum brush mounted on a front lower surface thereof; and a height adjusting apparatus set to an active mode or an inactive mode. In the active mode, the height adjusting apparatus raises the rear portion of the suction port assembly from an initial height, with the drum brush spaced from a surface, to bring the drum brush into contact with the surface when the cleaner body tilts from an upright position towards the rear of the suction port assembly. In the inactive mode, the rear portion of the suction port assembly remains at the initial height when the cleaner body tilts from the upright position towards the rear of the suction port assembly.

Abstract: An upright vacuum cleaner that includes a suction assembly, a cleaner body, a supporting member, and mounting parts. The cleaner body has a dust collecting unit which is in communication with the suction assembly. The supporting member is formed as a single frame with a lower end hinged to the suction assembly. The cleaner body is detachable from a front surface of the supporting member. A width of the supporting member is narrower than the cleaner body. The mounting parts are formed on a rear surface of the supporting member and are provided in a longitudinal direction with respect to the supporting member. The mounting parts are also shaped to mount accessories.

Abstract: A multi-cyclone dust-collecting apparatus for a vacuum cleaner mounted in a main cleaner body to separate dust from air flowing from a suction port body and collect the dust separated from the air, the apparatus including a dust-separating unit including a primary cyclone unit to separate large dust particles contained in the air flowing from the suction port body, and a secondary cyclone unit that is disposed inside the primary cyclone unit and that tapers downwards; and a dust-collecting unit detachably mounted in a lower portion of the dust-separating unit, the dust-collecting unit including a first dust-collecting chamber to collect the large dust particles discharged from the primary cyclone unit, and a second dust-collecting chamber disposed inside the first dust-collecting chamber to collect fine dust particles discharged from the secondary cyclone unit. The first dust-collecting chamber may be greater in volume than the second dust-collecting chamber.
