Abstract:
A robot cleaner including a suction hole to suction dust, a blower to generate a suction force to suction the dust, a dust collector to receive the dust suctioned by said suction force through the suction hole, and a rotating brush to sweep up and collect the dust into the dust collector through the suction hole by a drive force of the rotating brush. The dust collector includes a backflow preventing member movable between an open position and a closed position. The backflow preventing member is pivotably rotatable in an air suction direction by the suction force of the blower to the open position and is adapted to return to the closed position to prevent the dust in the dust collector from being discharged through the suction hole upon stoppage of the blower.
Abstract:
A wavelength-converted light emitting diode (LED) chip is provided. The wavelength-converted LED chip includes an LED chip and a wavelength-converted layer. The LED chip emits light in a predetermined wavelength region. The wavelength-converted layer is formed of a resin containing phosphor bodies of at least one kind which convert a portion of the light emitted from the LED chip into light in a different wavelength region. The wavelength-converted layer is formed on an upper surface of the LED chip, and has a convex meniscus-shaped upper surface.
Abstract:
Embodiments of a spindle motor are provided. A spindle motor can include a base in contact with a bearing housing, a bearing installed in the bearing housing, a rotational shaft rotatably supported by the bearing, a stator disposed around the bearing housing and having a coil, a rotor including a rotor yoke fixed on the rotational shaft and a magnet fixed on the rotor yoke, a turntable provided above the rotor yoke and rotating together with the rotational shaft, and a plurality of balls provided in a space defined by the rotor yoke and the turntable.
Abstract:
An antenna ground structure of a mobile terminal is disclosed. The antenna ground structure of a mobile terminal is arranged to provide the ground pattern on a Printed Circuit Board (PCB) adjacent to the antenna and to electrically connect the ground pattern to the ground unit of the antenna, so that the area of the ground of the antenna may be expanded to improve Specific Absorption Rate (SAR) and communication performance.
Abstract:
A home appliance and home appliance system are provided which enable a portable terminal not to recognize an acoustic signal sound corresponding to product information output by the home appliance as noise. Thus, the acoustic signal corresponding to product information output by the home appliance may be transmitted to a service center through the portable terminal. The home appliance may include a controller that sets a dead time at a predetermined interval of time with respect to a signal corresponding to product information to avoid a noise detection section of a portable terminal, a converter that converts the signal into an acoustic signal of a predetermined band, and a sound output device that outputs the acoustic signal as sound.
Abstract:
A portable personal self-operating life tube is disclosed, in which when a user is drowned in water due to a marine disaster or a fire and sinking of a ship, it automatically operates, so the user can save his life by just wearing the tube, and the tube is able to keep a user's a body temperature until a rescue comes after the tube is expanded along with the above features, and a life tube can be easily used without a particular care by improving the problems found in a conventional art in which a user feels bad when wearing a life tube since a conventional life equipment is not customized, and it is not portable and is not easy to use.
Abstract:
Embodiments of a profile motor are provided. A spindle motor can include a base in contact with a bearing housing, a bearing installed in the bearing housing, a rotational shaft rotatably supported by the bearing, a stator disposed around the bearing housing and having a coil, a rotor including a rotor yoke fixed on the rotational shaft and a magnet fixed on the rotor yoke, a turntable provided above the rotor yoke and rotating together with the rotational shaft, and a plurality of balls provided in a space defined by the rotor yoke and the turntable.
Abstract:
An apparatus for providing duplicated shelf managers in an ATCA system is provided. The apparatus for providing duplicated shelf managers includes a hub/switch in a control backplane to allow a manager to access the duplicated shelf managers all the time from an external network while maintaining the switch configuration defined of the ATCA specification. The hub/switch connects Ethernet ports of the duplicated two shelf managers and Ethernet ports of the two switches at the same time, and connects the two shelf managers and the two switches to the Internet.
