Abstract: A multilayer electronic component including: a body including a dielectric layer and internal electrodes; and external electrodes disposed outside the body and connected to the internal electrodes, wherein 1.5?Hfs/Hfc?5.0 when the internal electrode includes hafnium (Hf), Hfc indicates an average Hf content (at %) in a center of the internal electrode, and Hfs indicates an average Hf content (at %) in the internal electrode, measured from the center of the internal electrode to an interface thereof in contact with the dielectric layer.

Abstract: An electric appliance and a control method thereof are disclosed. The electric appliance includes a communication device connected with a smart grid net to recognize electric power information including power-rate information for each time period, a sensing device configured to sense a predetermined operation mode and an operation state according to the operation mode, and a control device configured to implement power-saving operation based on the received electric power information and the state information sensed by the sensing device.

Abstract: Disclosed is a control apparatus and method of a clothes treating machine. Power consumption can be expected or detected when an operation of the clothes treating apparatus is determined, and greenhouse gas emissions to an energy source or electricity prices according can be expected on the basis of power consumption. In addition, reasonable operations can be determined on the basis of recommended operation conditions provided by the clothes treating apparatus, and power consumption of the clothes treating machine, greenhouse gas emissions to an energy source or electricity prices can be easily calculated without providing an additional complicated power detection circuit.

Abstract: A fan apparatus and an air conditioner employing such a fan apparatus are provided to reduce noise and enhance efficiency. The fan apparatus may be driven by a BLDC motor that stably drives the fan and increases an air flow rate. Heat exchange efficiency of an outdoor unit of a front suction/discharge type air conditioner may be improved by such a fan apparatus driven by such a BLDC motor.

Abstract: The present invention provides a fan apparatus which can reduce noise and enhance fan efficiency by employing a BLDC motor that can make stable drive of the fan and increase an air flow rate, and an outdoor unit of a front suction/discharge type in an air conditioner that can enhance heat exchange efficiency by employing the same.

Abstract: Fan apparatus including a fan, a shaft coupled to the fan for transmission of driving force from a motor to the fan, a rotor bushing of an insulating material joined to a rear end portion of the shaft, a rotor joined to the rotor bushing for transmission of the driving force to the shaft through the rotor bushing, and a stator mounted so as to be positioned on an inside of the rotor to form a BLDC motor together with the rotor, thereby reducing noise and enhancing fan efficiency by employing the BLDG motor which can make stable operation of the fan and increase an air flow rate.

Abstract: Apparatus and method for determining the condition of the floor to be cleaned by a cleaning robot. The apparatus comprises an ultrasonic wave signal transmitting circuit for transmitting an ultrasonic wave signal to an ultrasonic wave signal transmitter under the control of a microcomputer, a receiving amplifying unit for amplifying the ultrasonic wave signal transmitted from the ultrasonic wave signal transmitter and received in a ultrasonic wave signal receiver, a receiving demodulating unit for smoothing the output signal from the receiving amplifying unit to demodulate it and then apply it to the microcomputer. According to the control of the microcomputer, the ultrasonic wave signal is transmitted for a predetermined period. The period from the time when the ultrasonic wave signal is transmitted to the time when the ultrasonic wave signal is received in the ultrasonic wave signal receiver is measured.
