Abstract:
An apparatus, system and method for implementing a video call between a first caller and a second caller are provided. The apparatus includes: an image sensor which captures an image of the first caller; a display which displays an image of the second caller; a microphone which captures an audio input by the first caller; a speaker which outputs an audio input by the second caller; a detector which is configured to determine a location of the first caller; and a controller which controls the detector to determine the location of the first caller as corresponding to an original location, wherein in response to the first caller changing a location from the original location to a new location, the controller controls the detector to determine the location of the first caller as being the new location, and controls the microphone to adjust a configuration of the microphone based on the new location of the first caller.
Abstract:
Disclosed herein are a door guard assembly and a refrigerator having the same. In the door guard assembly, one side of a storage space of the door guard where food is stored is formed of a wooden material so that humidity of the storage space is adjusted.
Abstract:
A bendable flexible flat membrane module includes: a membrane facing each other and constituting both outer surfaces; a support member made of a flexible material and embedded inside the membrane constituting the both outer surfaces; and a plurality of point bonding portions formed by pressing and bonding the both outer surfaces facing each other at a predetermined point.
Abstract:
Provided are an apparatus, system and method for facilitating a video call between a first caller and a second caller, the apparatus including: an image sensor which captures an image of the first caller; a display which displays an image of the second caller; a microphone which captures audio input by the first caller; a speaker which plays audio input by the second caller; a detector which is operable to determine a location of the first caller; and a controller which controls the detector to determine the location as corresponding to an original location, wherein if the first caller changes from the original location to a new location, the controller controls the detector to determine the location as being the new location and controls the microphone to readjust based on the determined new location of the first caller.
Abstract:
Disclosed herein is an apparatus for forming a hole in a spongelike bone. The apparatus includes a catheter tube, an expansible structure coupled to a front end of the catheter tube, a hub having a fitting coupled to a rear end of the catheter tube, and a probe. The catheter tube includes the probe and one lumen surrounding the probe, both of which are disposed inside the catheter tube. The probe is fixed to the hub or a rear cap of the hub at a rear end thereof and comes into contact with an inner front end of the expansible structure at a front end thereof.

Abstract:
A refrigerator has a variable shelf which may include a first partition shelf mounted to be pivotable about a rear end thereof, and a second partition shelf mounted to move relative to the first partition shelf and therefore protrude to a front of the first partition shelf. When the fist and second partition shelves are rotated about the rear end of the first partition shelf in a state where the second partition shelf is disposed at a lower part of the first partition shelf, it may be guaranteed a storage space even for item(s) higher than an interval between the shelves and wider than a front-to-rear width of the second partition shelf.
Abstract:
The refrigerator includes a main body provided with a first storage compartment and a second storage compartment, vertically divided from each other. a first storage compartment door and a second storage compartment door are vertically disposed so as to open and close the first storage compartment and the second storage compartment of the main body. an illumination unit is provided at least one of the lower end portion of the first storage compartment door and the upper portion of the second storage compartment. Also an input unit is provided to input operation data of the illumination unit.
Abstract:
A fast adaptive channel converting method and apparatus, and a computer readable recording medium having recorded thereon a program to execute the fast adaptive channel converting method. The fast adaptive channel converting method includes generating adjacent channel data by pre-signal processing an adjacent channel signal of a reference channel, receiving a channel change request from a user, searching for channel data corresponding to a changed channel in the adjacent channel data, and reproducing the searched channel data. Unlike a conventional technology, the fast adaptive channel changing apparatus and method prevents a screen blank time that may occur while changing a channel in a digital broadcast receiving apparatus, and thus boredom or inconvenience of a user can be removed. Also, when a channel is changed by using a preferred channel list, a channel search time can be remarkably reduced, and the user can easily watch a program of a preferred channel.
Abstract:
An amplitude-type Fresnel zone plate for focusing incident X-rays is formed in a single-crystal layer. For incident X-rays that are above a threshold energy level and that are directed at the zone plate at a specified angle, Bragg reflection occurs from crystallographic planes within the elements of the zone plate even when the layer is exceedingly thin. Accordingly, zone plates with extremely narrow elements may be fabricated. In turn, this allows the realization of zone plates capable of focusing X-rays to very small spot sizes.
