Abstract: This disclosure includes magnetic field correction devices and methods for using the same. Some magnetic field correction devices include an arch-shaped body configured to be worn inside or outside of a user's mouth such that the arch-shaped body follows the contour of the user's teeth or face, where the arch-shaped body has one or more sidewalls and where the sidewalls are configured to receive a plurality of ferromagnetic or magnetic members. Some of the present methods include performing magnetic resonance imaging (MRI) on a user having one or more magnets coupled to an apparatus disposed inside or outside and adjacent to the user's mouth. Others of the present methods include coupling a plurality of magnets to an arch-shaped body configured to be worn by a user, where the magnets are configured to reduce artifacts caused by non-biological materials within the user's mouth during MRI.

Abstract: A microwave oven includes a tray rotatably installed inside a cooking compartment, a temperature measuring apparatus comprising a driving unit configured to generate a rotation force, and a sensing unit configured to measure the temperatures of a plurality of temperature measurement points by having a temperature measurement angle changed by the rotation force of the driving unit; and a control unit configured to control the temperature measuring apparatus to measure the plurality of temperature measurement points provided at the upper side of the tray according to a predetermined temperature measurement pattern that provides a different pattern for successive rotation periods of the tray.

Abstract: A refrigerator including an icemaker and an ice bucket provided at a door, a feeding unit to feed ice cubes stored in the ice bucket, a driving motor provided at a main body to drive the feeding unit, and a coupling device to transmit driving force from the driving motor to the feeding unit. When the door is closed, the driving motor is connected to the feeding unit. When the door is opened, the driving motor is disconnected from the feeding unit. Accordingly, the door has a simple structure, the ice bucket has an increased capacity, repair or replacement of the driving motor is easily achieved. The coupling device includes a first coupling unit and a second coupling unit which is engaged with the first coupling unit to receive driving force. The coupling device is configured to hide the coupling units when the door is opened.

Abstract: A washing machine having an improved structure which increases washing capacity without increasing the size of the washing machine. The washing machine includes a cabinet including an outer part and a cylindrical inner part connected to the outer part, a spin basket rotatably disposed in the inner part and including a bottom and a side wall extending from the bottom, a pulsator rotatably disposed in the spin basket, a motor provided under the spin basket, a clutch to selectively transmit power of the motor to the spin basket or the pulsator, a base plate to fix the clutch and the motor, and suspension members connecting the base plate to the upper portion of the cabinet. Wash water is stored within the spin basket and is not stored outside the spin basket during a washing cycle.

Abstract: A method for measuring the amount of electric power consumption of a refrigerator comprises the steps of: measuring the amount of electric power consumption and a time of a defrosting cycle in a refrigerator during operation of a defrosting heater after starting a measurement of the amount of electric power consumption and during two cycles of operating a compressor after operating the defrosting heater; measuring the average of electric power consumption per cycle and the average of operating time per cycle in the refrigerator during performance of refrigerating cycles after the defrosting cycle; and calculating the total amount of electric power consumption of the refrigerator using the amount of electric power consumption during the performance of the defrosting cycle, the average amount of electric power consumption of the refrigerator during the performance of the refrigerating cycle, the time for performing the defrosting cycle, and the average time for performing the refrigerating cycle.

Abstract: A power consumption prediction method and apparatus for a refrigerator having a defrosting heater is provided. In the power consumption prediction method, a defrosting timer cycle expressed as a cumulative value of an operation time of a compressor is set. The defrosting heater is activated to perform forced defrosting. The compressor is activated so that cooling cycles are completed several times. A defrosting time, a pause time and an operation time of the compressor and the energy consumed during each time are respectively detected. Based on the detected results, a unit run cycle of the refrigerator corresponding to the defrosting timer cycle is estimated. The energy consumption for a predetermined interval of time is estimated. Accordingly, the test time for power consumption prediction for the refrigerator can be shortened.

Abstract: A refrigerator which has a device for opening/closing cool air discharge ports is disclosed. The device includes plates for opening/closing the ports, and a driving device for driving the plates. The heat exchange between an evaporator and the outside warm air is prevented during the defrosting operation when a door is open. Hence the cooling efficiency is enhanced and the frost caused by the outside warm air is not generated on the evaporater.
