Abstract: Disclosed herein is a refrigerator. The refrigerator includes a body; a fresh food compartment provided in an upper portion of the body, a freezer compartment provided in a lower portion of the body, an upper door configured to open or close the fresh food compartment, a lower door configured to open or close the freezer compartment, a first dispenser provided in the upper door and configured to provide water, and a second dispenser provided in the lower door and configured to provide ice.

Abstract: Disclosed herein are a refrigerator and method of controlling the same. A refrigerator includes an interface unit configured to receive a command for supplying at least one of water and ice from a user; a weight sensor configured to measure a weight of a container placed on a container supporter; and a controller configured to control a supply of the at least one of water and ice based on a change in weight of the container based on the measured weight of the container.

Abstract: A transducer is provided.

Abstract: A water pocket with an open top side is filled with water, mounted in a regular position on a supporting frame, and tilts to supply the water stored in the water pocket to an ice making tray, thereby easily supplying a required amount of water to the ice making tray. A refrigerator includes an ice making tray provided to linearly move with rotation when ice of the ice making tray is separated, or includes a holding preventing member which prevents the ice from being caught by a lower ice making tray, thereby improving a forward-and-backward width of an ice maker. It is possible to easily withdraw ice stored in an ice bucket by pushing an ice discharge button in a state in which the ice bucket is not separated.

Abstract: Disclosed herein are a food storage apparatus with improved security performance due to performing of a lock/unlock function from far away and a method of controlling the same. Also, provided are a food storage apparatus which allows a user far away to take appropriate measures by reporting approach of an unauthorized person, opening of a door, etc. or to check a thief or stolen food and a method of controlling the same. The food storage apparatus includes a body in which a storage space for storing food is formed, a door installed on the body to be openable, a locking unit which locks the door, a communication unit which communicates with an external terminal to receive a locking command, and a control unit which controls the locking unit to lock the door when the locking command is received from the terminal.

Abstract: Disclosed herein are a refrigerator of sensing a degree of rancidity of fermented liquor to transmit state information of the fermented liquor to a remote user, and a method of controlling the refrigerator. The refrigerator may include a storage space configured to store fermented liquor; a cooling unit configured to cool inside air of the storage space; a rancidity sensor configured to sense a degree of rancidity of the fermented liquor; and a communication unit configured to transmit state information of the fermented liquor created based on the degree of rancidity to a predetermined external device.

Abstract: A cover for an electronic device with a stand function is provided. The cover is detachable from the electronic device. The cover includes a frame that is detachably coupled to the electronic device at least one of a side surface and a rear surface of the electronic device, a cover member that is rotatably connected to one side of the frame and bendable on at least one bending line included therein, and a protrusion portion that protrudes from the frame, wherein the cover member supports the electronic device at an incline, when the cover member is bent along the at least one bending line and the protrusion portion rests on an edge of the cover member.

Abstract: A refrigerant recovery operation method for use in a refrigerator in which a freezing chamber and a refrigerating chamber are independently cooled is disclosed. The refrigerator and the method for controlling the same guarantee a sufficiently long refrigerant recovery operation time by performing the refrigerant recovery operation not only when the compressor starts operation but also before the compressor stops operation, resulting in implementation of the highest operation efficiency of a refrigerating chamber. The refrigerator guarantees high reliability of the compressor by increasing the refrigerant recovery amount within a predetermined pressure range in which the compressor can operate, and maintains an optimum refrigerant amount by variably controlling the refrigerant recovery operation time according to the outdoor air temperature, resulting in improvement of energy efficiency.

Abstract: The aim of the present invention is to provide a waveguide capable of transmitting shear waves in a desired pattern to a bulk-type medium, a vibrator, and a method of transmitting shear waves by using the vibrator. To this end, the present invention provides a waveguide including a vibrating portion that is vibrated by a vibrating unit, a transmitting portion that transmits shear waves generated by the vibrating unit to a bulk-type medium and is thicker than the vibrating portion, and a connecting portion that contacts both the vibrating portion and the transmitting portion and has a thickness varying from a portion contacting the vibrating portion to a portion contacting the transmitting portion. Also, the present invention provides a vibrator using the waveguide and a method of transmitting shear waves by using the vibrator.
