Abstract: An aspect of the present disclosure is to provide a refrigerator and a method of controlling the same that protects privacy by designating a user in each storage chamber and allowing only the designated user to use the storage chamber in order to protect the privacy of each user and preventing mishandling of items stored in the refrigerator in advance when the plurality of users share a refrigerator, and prevents mishandling of stored items by prohibiting the use of the storage chamber other than the designated storage chamber. The refrigerator includes a display; a storage chamber configured to allow use only by authorized users; and a controller configured to display information of the storage chamber through the display in response to the completion of user authentication of the storage chamber.

Abstract: A communication apparatus to interconnect a plurality of devices using multiple protocols includes a protocol layer having a plurality of protocol objects obtained by objectifying the protocols used by the devices, and a control layer to check a protocol used for data transmission if data is transmitted, to convert a protocol object corresponding to the checked protocol into a preset control object, to convert the preset control object into another protocol object, and to transmit the data to a device connected to the converted other protocol object. Since operatively coupled control is allowed between devices using different protocols, extensibility and flexibility may be achieved. Besides, since an abstraction layer is divided into a control layer and a protocol layer, an interface may not be changed even when protocols are added, protocol conversion may be easily performed, and routing between multiple protocols may be performed using, for example, a logic editor.

Abstract: A method and apparatus for displaying a User Interface (UI) in a portable electronic device through a sub device is provided. The method includes sensing, by the portable electronic device, an input corresponding to displaying of a popup menu, which is provided by an application, on the sub device, transmitting UI configuration information corresponding to the popup menu to the sub device, receiving, from the sub device, user input data corresponding to a user input sensed on the popup menu that is displayed on the sub device, and controlling execution of the application in response to the received user input data.

Abstract: A group recording method for an electronic device is provided. The method includes establishing a connection between the electronic device and at least one other electronic device through wireless communication, acquiring a first image created by photographing a target subject, acquiring a second image created by photographing the target subject from the another electronic device, and concurrently recording by the electronic device the first image and the second image and displaying the first image and the second image together on a display screen, in which a second viewpoint corresponding to the second image is different from a first viewpoint corresponding to the first image.

Abstract: An electric device includes a communication unit to communicate with at least one of a gateway and a plurality of other electric devices, and a controller to broadcast a request signal for searching for a gateway, communicate with the gateway on the basis of a search response signal after transmission of the gateway response signal from at least one of the gateway and the plurality of other electric devices, and transmit a registration request signal to a power management unit through the gateway. Thus, the electric device can be automatically registered/re-registered in the electric device or be deleted from the electric device, a power management system and electric devices can be easily managed. If the user moves the electric device from a current position to another position, the power management system recognizes the movement and informs the user of the recognition result.

Abstract: A protocol conversion apparatus and a protocol conversion method. The protocol conversion apparatus includes a first control to analyze first protocol data received through a first channel, a protocol mapper to determine whether protocol conversion is required for the first protocol data, and a second control to create second protocol data associated with the first protocol data based on a result of the determination, and to transfer the second protocol to a second channel.

Abstract: An electronic device and method of mirroring screen data is disclosed. The method includes communicatively coupling with an external display device, mirroring screen data displayed on a display of the electronic device by transmitting the screen data to the external display device for display, and in response to detection of a preset event, removing a subset of the screen data associated with the preset event, so that the subset is not displayed on the external display device.
