Abstract:
The present invention discloses an apparatus for supercooling and a method of operating the same which can solve supercooling release of a supercooled space and prevent external exposure of energy such as an electric field. The apparatus for supercooling includes a space cooled by cool air, for maintaining an inside object in a supercooled state by supply of energy preventing the object from being converted into a solid phase, a sensing unit for sensing supercooling release of the space or the object, and a heater engaged with the sensing unit, for applying heat to the space or the object.
Abstract:
A refrigerator is provided having a user avatar display function which can store avatars of each user, identify users, and display the avatars corresponding to the identified users. The refrigerator includes a photographing device that photographs images of users, a storing device that stores user information for identifying the users and avatar information having avatars corresponding to the users and/or user information, a display that displays the avatars, and a controller that reads the user information, compares the user information with the images of the users photographed by the photographing device, reads the avatar information according to the comparison result, and displays the avatars of the users included in the read avatar information on the display.
Abstract:
The present invention discloses an ice maker including an ice tray (51) for containing water and making ice, and at least one energy generator (54) disposed to supply energy to at least one of the water contained in the ice tray and the ice made in the ice tray, and a method of making ice.
Abstract:
A service handover control apparatus and a method using the apparatus are provided. The service handover control apparatus includes a service handover management unit collecting information associated with a transmitting terminal and a wireless access network, which operate based on an Internet Protocol multimedia subsystem (IMS), and outputting a control signal which controls service handovers of the transmitting terminal and the receiving terminal based on the collected information; and a service handover controller providing the service handover management unit with the information associated with the transmitting terminal and the receiving terminal, and controlling the service handovers of the transmitting terminal and the receiving terminal based on the control signal.
Abstract:
A method and apparatus for registering a Media Independent Handover (MIH) is provided. An MIH registration method includes transmitting, by a serving network, an MIH registration request of the serving network to at least one candidate network when an MIH registration request is received from a mobile terminal, the at least one candidate network corresponding to the serving network, receiving, by the serving network, a response to the MIH registration request of the serving network from each of the at least one candidate network, and transmitting, by the serving network, a response to the MIH registration request of the mobile terminal to the mobile terminal.
Abstract:
A method of providing a handover service to a mobile communication terminal supporting multi-modal communications, and a mobile communication terminal for performing the method are provided. More particularly, a method of eliminating an interruption of a data transmission service occurring during a handover between different communication networks, and a terminal for performing the method are provided. A method of providing a handover service of a mobile communication terminal supporting multi-modal communications can include: transmitting and receiving data to/from a corresponding node via a first access network and a second access network while simultaneously maintaining an association with the first access network and the second access network, determining a point in time of completing a handover registration, and releasing an association with the first access network after the point in time of completing the handover registration.
Abstract:
A refrigerator includes a valve assembly located at a refrigerant path from a condenser to at least one expansion valve for controlling flow of a refrigerant from the condenser to the at least one expansion valve. The valve assembly includes a valve chamber, wherein the refrigerant drawn from the condenser is held in the valve chamber; at least one outlet hole through which the refrigerant held in the valve chamber is discharged to a corresponding outlet path connected to the at least one expansion valve; and a valve body for selectively opening and closing the at least one outlet hole as the valve body rotates, such that the refrigerant held in the valve chamber is selectively discharged to the corresponding outlet path.
Abstract:
The present invention discloses a refrigerator which can perform direct cooling of circulating cool air by natural convection in a freezing chamber (F) and a refrigerating chamber (R), and which can selectively perform indirect cooling of circulating cool air by forcible convection in the refrigerating chamber. It is like that, frost or condensed water formed in the refrigerating chamber (R) of the direct cooling type refrigerator does not Influence the inside of the refrigerating chamber. In addition, the refrigerator efficiently performs a defrosting operation of the refrigerating chamber (R), sanitarily performs a cooling operation, and maintains uniform cooling performance.
Abstract:
A system and method for reserving resources for a Mobile Node (MN) having a plurality of wireless network interfaces in a mobile network under a multi-homed environment are provided, wherein the MN transmits query messages requesting a path be setup to a plurality of Access Routers (ARs) accessible through the wireless network interfaces, a Crossover Router Node (CRN), shared by a plurality of paths running to a CN via the ARs, selects an optimal path from among the plurality of paths using the path information set in the query messages propagated through the plurality of paths, the CRN transmits the resource reserve message through the selected optimal path, and the routers existing in the optimal path reserve resources according to the resource reserve message.
Abstract:
The present invention relates to an apparatus for forming polymer by DC plasma polymerization wherein a substrate is used as an electrode by applying a power to the substrate and an opposite electrode in a deposition chamber is positioned to both the surfaces of the substrate to be deposited. In addition, the present invention can acquire safety during the polymerization by insulating a main body from a substrate to which voltage is applied.
