An apparatus and method that stabilizes an output sequence of a real random number generator by adjusting the input voltage of the random number generator or the comparative voltage of a comparator. The apparatus for stabilizing an output sequence of a real random number generator includes a verification unit for performing a monobit test on random number values sampled by and output from a comparison unit, and calculating an impact value. An adjustment unit adjusts a voltage of any one of a random number generation unit and the comparison unit using resulting values of the monobit test and the impact value output from the verification unit.

A portable terminal is provided. The portable terminal includes a main housing, a sub housing, a mainboard, and an electric connector. The main housing has a first antenna radiator. The sub housing is separable from the main housing and has a second antenna radiator. The mainboard is disposed in the main housing and processes a radio signal. The electric connector is disposed in the main housing. When the sub housing and the main housing are separated from each other, the electric connector electrically connects the mainboard with the first antenna radiator of the main housing. When the sub housing and the main housing are coupled, the electric connector electrically connects the mainboard with the second antenna radiator of the sub housing.

A vacuum cleaner having a dust removing apparatus includes a main body in which a dust collecting unit is disposed, a filter disposed inside the dust collecting unit, the dust removing apparatus to dust off the filter, a rotating handle that allows the dust removing apparatus to be rotated, the rotating handle disposed in an outer surface of the dust collecting unit, and a body cover in which a rotating-handle exposing hole is formed for the rotating handle to be exposed outside in a state that the dust collecting unit is disposed in the main body, the body cover rotatably disposed at the main body. The vacuum cleaner can remove dust from filter regardless whether the dust collecting unit is disposed in or separated from the main body. The vacuum cleaner also can remove dust from the filter while the vacuum cleaner operates.

Vacuum cleaner provided with dust-removing device

Disclosed is a vibration module for a portable terminal that includes a housing, a magnetic moving part movable in a first direction within the housing; an elastic member supported between the opposite ends of the magnetic moving part and inner walls of the housing, and a solenoid coil provided in the housing. The vibration module is positioned at one end of the moving section by the magnetic force of the magnetic moving part and an object around the magnetic moving part, allowing the vibration module to provide a user with a feeling similar to a click feeling via the acceleration produced at a stopping instant. In addition, when vibrating, the vibration module generates sufficient vibration power through acceleration at the instant of changing moving direction at the ends of the moving section, to provide an alarm function, such as an incoming call notification.

A filter assembly for a vacuum cleaner is provided, and the filter assembly comprises a discharge grill formed on a discharge passage, a filter member mounted on the discharge grill, and a gasket member that is detachably connected between the discharge grill and the filter member and seals a space between the discharge grill and the filter member.

Filter assembly for vacuum cleaner

A cyclone dust-separating apparatus includes a cyclone unit having air inflow and air outflow parts that separate dust or dirt from air, the cyclone unit being installed such that a longitudinal axis thereof is substantially horizontally arranged; a dust bin joined to a bottom end of the cyclone unit that collects the dust or dirt separated by the cyclone unit, the dust bin installed in such a manner that a longitudinal axis thereof is substantially perpendicular to the longitudinal axis of the cyclone unit; a nonporous envelope detachably disposed in the dust bin that stores the dust or dirt collected into the dust bin; and a pressure difference-generating passage to communicate an outlet of the air outflow part and the dust bin with each other so as to allow the nonporous envelope to come in contact with an inner surface of the dust bin by a pressure difference between the dust bin and the air outflow part.

Cyclone dust-separating apparatus of vacuum cleaner

A power cord cooling apparatus disposed in a cord reel chamber formed inside a main body of the vacuum cleaner to cool a power cord wound around a cord reel, wherein the power cord cooling apparatus allows outside air to enter the cord reel chamber, to contact the power cord wound around the cord reel, and to be discharged outside the cord reel chamber via a center space in the cord reel.
