A refrigerator of this embodiment includes a housing that includes a storeroom, a door that is rotatably provided in the housing through a hinge portion and opens or closes an opening of the storeroom by the rotation, a connection line that is led out to the vicinity of the hinge portion, and a wireless communication apparatus that includes a wireless communication unit and is connected to the connection line.

A feedback-based device for nucleation control is provided. A supercooling tray is sized to hold an object. Field generators include at least one magnet or transducer positioned with respect to the supercooling tray and a pair of electrodes located on opposite sides of the supercooling tray. One or more feedback sensors are configured to determine characteristics of the object at one or more spatial locations at multiple time points and each feedback sensor includes one of a reflectivity, electrical, acoustic, or hyperspectral sensor. A controller is configured to determine supercooling parameters based on the characteristics determined at the multiple time points and to control application of a field directed at the object by the field generators based on the supercooling parameter.

In a refrigerator and control method thereof according to the present disclosure, when a load operation is terminated and a normal storage operation is performed, a re-input prevention control is performed to prevent the load operation from being performed even if an operation start condition of the load operation is satisfied. During the re-input prevention control, when a re-input prevention stop condition is satisfied, the re-input prevention control is controlled to be stopped. In this way, it is possible to prevent over-cooling of a first storage compartment, which may be caused by continuous input of the load operation, and respond smoothly to the corresponding load when a large load is input.

Disclosed is a method of storing food in an artificial intelligent refrigerator including obtaining an image of a storage chamber through a camera installed in the storage chamber of the refrigerator; transmitting the obtained image to a server; receiving a recognition result of food newly stored in the storage chamber through AI image processing in the server from the server; and displaying notifying information related to the food in a display unit of the refrigerator based on the received result.

A refrigerator is provided having at least one internal refrigerated compartment in which a plurality of refrigeration zones are provided, wherein an environment in each refrigeration zone may be independently controlled using a user interface configured to receive a zone selection input from a user indicating one of the plurality of refrigeration zones in which the user desires to adjust the environment; a plurality of lights provided in the internal refrigerated compartment and disposed proximate to each of the plurality of refrigeration zones, wherein groups of the plurality of lights may be separately controlled for visually identifying each of the refrigeration zones; and a controller configured to receive a zone selection input from the user interface, identify a group of the plurality of lights that are disposed proximate the selected refrigeration zone, and control the identified group of the plurality of lights to visually confirm the selected refrigeration zone.

A refrigerator is provided. The refrigerator may include a main body having a storage compartment, a first door rotatably installed at a first side of the main body to open and close a first portion of the storage compartment, and a second door rotatably installed at a second side of the main body to open and close a second portion of the storage compartment. A first camera may be installed at the first door to take a picture of an interior of the first storage compartment during rotation of the first door, and a second camera may be installed at the second door to take a picture of the interior of the first storage compartment during rotation of the second door. A controller may combine plural pictures taken by the first camera and the second camera into a single corrected image of a region of the first compartment spanning from the first door to the second door.

The present disclosure relates to a cryocooling system and method. The system includes a sample well and a sample chamber, each of which having an interior that is sized and shaped to hold a cryocooling gas at cryogenic temperatures and a pressure below 1 atm. The sample chamber is also sized and shaped to hold a sample substance to be cryocooled. An impedance tube connects the interior of the sample well to the interior of the sample chamber to allow cryocooling gas to move from the sample well to the sample chamber. A vacuum tube is connected to the interior of the sample chamber on one side and to a vacuum pump via a vacuum port on the other. The vacuum tube is sized and shaped to allow cryocooling gas within the sample chamber to be pumped out of the sample chamber by the vacuum pump.

A cooler assembly includes an insulted main container and a pump assembly configured to pump contents of the main container through a tube to a spigot. An electronic control board includes a pressure-sensing switch that senses pressure differentials or fluid movement when the spigot is opened and closed, causing a triggering event. Triggering events are used to activate and deactivate the pump to dispense fluid from the main container.
