A refrigerator including: an inner case defining a storage compartment and including a plurality of plates respectively formed by injection molding; an outer case coupled to an outer side of the inner case; and an insulation material interposed between the inner case and the outer case. A first plate among the plurality of plates includes a first front flange defining a part of a front surface of the inner case, and a second plate among the plurality of plates includes a second front flange defining another part of the front surface of the inner case and coupled to the first front flange.

Refrigerator

A wireless power transmission device can include a plurality of transmission coil units, in which each of the plurality of transmission coil units includes a plurality of antenna coils arranged on different three-dimensional planes, and the plurality of antenna coils are configured to generate a magnetic field passing through at least one or more of the different three-dimensional planes to transfer transmission power to a wireless power reception device.

Wireless power transmission device

A wireless power transmission device comprises a plurality of transmission coils having different inductances and a controller. The controller wirelessly transmits a first transmission power to the electronic apparatus through a first transmission coil among the plurality of transmission coils, obtains whether it is an under-coupling mode or an over-coupling mode, when receiving power shortage information from the electronic apparatus, changes from the first transmission coil to a second transmission coil according to the obtained mode, and wirelessly transmits a second transmission power to the electronic apparatus through the changed second transmission coil. The second transmission coil is one of the remaining transmission coils except for the first transmission coil among the plurality of transmission coils.

Wireless power transmission device and electronic apparatus

According to an embodiment, an electronic device comprises a memory, a communication module, a first speaker including at least one vibration component, at least one first microphone, and a processor configured to output a first sound having a predetermined frequency via the first speaker when a closed space is formed with the electronic device mounted on a cradle, obtain a third sound, which is a reflection of the first sound in the closed space, via the at least one first microphone, obtain a fourth sound, which is a reflection of a second sound in the closed space, via the at least one first microphone, the second sound output from a second speaker included in an external electronic device located in the closed space, and identify whether the performance of the first speaker, the at least one first microphone, and the second speaker is normal, based on the third sound and the fourth sound.

Electronic device for outputting sound and method for operating the same

A refrigerator including a cabinet including an insulator provided between an inner case and an outer case, a cold air duct embedded in the insulator to circulate cold air through the storage compartment, a cooling module mounting unit provided at a lower portion of the cabinet, and a cooling module including a module body in which an evaporator, a condenser, a compressor, and a cooling fan are installed and having an accommodating portion to accommodate the evaporator in a lying state, the cooling module being provided with a connection opening communicating with the cold air duct when mounted on the cooling module mounting unit.

An apparatus and method for measuring a temperature in an electronic device. An amount of light of an optical signal reflected off of an object is measured, and a size of a temperature measurement expectation area on the object based is determined based on the measured amount of light. A temperature measurement guide message is output based on a result of comparing the determined size and a reference area.

Apparatus and method for measuring temperature in electronic device

A data storage system and a data storing method for the data storage system are provided. The data storage system includes a host unit, a storage unit, and a first input/output bus functioning as an interface between the host unit and the storage unit. The storage unit includes a non-volatile memory buffer unit and a flash memory unit. The non-volatile memory buffer unit includes a plurality of buffers arranged in parallel. The flash memory unit includes a plurality of data storage devices arranged in parallel to input and output data using a parallel method. In the method, a writing request is first classified into one of a plurality of grades according to a writing request frequency when there is a writing request and the writing requested data is stored in one of the non-volatile memory buffer unit and the flash memory unit according to the writing request frequency.
