Abstract:
An operation method of a first communication node may comprise: receiving one or more polarized radio signals transmitted from a second communication node included in the communication system through one or more receive polarized antennas included in the first communication node; performing a receive polarized antenna alignment state adjustment operation so that a detection result for a magnitude of an electric field excited by the one or more polarized radio signals is maximized; and receiving a first polarized signal transmitted from the second communication node through at least part of the one or more receive polarized antennas based on a result of the receive polarized antenna alignment state adjustment operation.
Abstract:
A cost-cognitive base station apparatus, a cost-cognitive user terminal, and a cost-cognitive network method, in which by recognizing costs based on network congestion, a user may select and receive appropriate network services, thereby reducing telecommunication expenses and inducing the user to a less congested network, which leads to improved network management efficiency.
Abstract:
The present invention relates to smart glasses, and the smart glasses include: a frame mounted with lens; a pair of temples extended in one direction from both side ends of the frame so as to face each other; a rear camera mounted at an end of the temple and configured to photograph a rear image of a wearer; a display unit installed at one side of the lens and configured to display the rear image photographed by the rear camera; and a control device configured to control an operation of each of the constituent elements, thereby enabling a user to check a situation in the rear view without turning his/her head.
Abstract:
An apparatus and a method for converting an upstream radio frequency (RF) signal to a digital signal and transmitting the digital signal via an Internet protocol (IP) packet based on an optical network in a cable broadcasting network is provided. The apparatus for transmitting an upstream RF signal includes a detector configured to detect an upstream RF signal, and a transmitter configured to digitize the detected upstream RF signal and transmit the digitized RF signal to a headend via an IP packet.
Abstract:
Disclosed is a terminal including: a social group creating unit which creates a social group on a social network service; a communication unit which transmits a search message to target terminals, configures communication connection with the target terminal by receiving a search response message which corresponds to the search message and includes a target social identifier from the target terminals, transmits an invitation message including a source social identifier and an access code to at least one target terminal which transmits the search response message among the target terminals, and receives an invitation response message corresponding to the invitation message from at least one target terminal; and a control unit which adds at least one target terminal to the social group based on the invitation response message.
Abstract:
A method performed in an apparatus based on touch screen may comprise grouping Korean consonants into at least one consonant-group and Korean vowels into at least one vowel-group and determining a delegate consonant for each of the at least one consonant-group and a delegate vowel for each of the at least one vowel-group; allocating the delegate consonant and the delegate vowel to independent keys in a predetermined order, and displaying the keys; and displaying at least one key corresponding to at least one family consonant belonging to a same group with the delegate consonant to a key selected among the displayed keys. Therefore, all Korean consonants and vowels can be inputted by using a restricted number of keys, and inputted quickly and easily without any learning or training.
Abstract:
An apparatus and a method for providing a surveillance image based on a depth image. The apparatus according to the present invention includes: a first camera capturing a depth image for a subject in a predetermined capturing region; a second camera capturing a color image for the subject in the predetermined capturing region; a subject identification unit identifying a subject in the capturing region; an image processing unit extracting the color image corresponding to a region of the identified subject from the color image and synthesizing the extracted color image with a position corresponding to the depth image to generate a synthesized image; and a control unit providing the depth image when the subject is not identified by the subject identification unit and providing the synthesized image only when the subject is identified by the subject identification unit.
