Abstract:
Disclosed herein are a method of transmitting data and a method of receiving data. In the method of transmitting data, a management frame including data to be transmitted is configured, and the configured management frame is transmitted. In the method of receiving data, a management frame is received and then data is read from the received management frame.
Abstract:
An apparatus for receiving data in a communication system includes: a detection unit configured to calculate power values of a data packet and a ratio of the power values by using a preamble of the data packet in a received signal, and detect the data packet through the calculated ratio of the power values; a control unit configured to calculate a gain compensation value of the detected data packet, and perform an automatic gain control (AGC) on the detected data packet by using the gain compensation value; a compensation unit configured to calculate a DC offset in the received signal, and remove the DC offset from the received signal; and a demodulator configured to demodulate the AGCed data packet.
Abstract:
A flat panel display device and a method of manufacturing the same. The method of manufacturing the flat panel display device includes: forming a display on a substrate; preparing an organic layer mask comprising a first mask body, a regulator extending from the first mask body and contacting the organic layer, and a tunnel having a space between the first mask body and the regulator; forming an organic layer covering the display in a region divided by the regulator of the organic layer mask, and condensing a part of the organic layer permeating through the tunnel; preparing an inorganic layer mask; and forming an inorganic layer covering the organic layers formed in the region divided by the regulator through the inorganic layer mask and in the tunnel.
Abstract:
Provided is a symbol timing estimating apparatus and method that may generate at least one sampled preamble signal by sampling a preamble signal with changing a phase of the preamble signal based on a symbol speed, calculate a power value of each of the at least one sampled preamble signal, and estimate a symbol timing of a sampled preamble signal having a maximum power value by comparing each power value among the at least one sampled preamble signal.
Abstract:
A magnetodielectric substrate includes a first dielectric layer, a second dielectric layer, conductive patterns, and a plurality of air vias. The first dielectric layer has a predetermined height, and the second dielectric layer is stacked on the first dielectric layer. Conductive patterns are coated on an upper surface and a lower surface of one of the first and second dielectric layers. A plurality of air vias is formed with a predetermined diameter and a predetermined interval such that they pass through up to the conductive patterns of the upper and lower surfaces from the dielectric layer on which the conductive patterns are coated.
Abstract:
Disclosed is a metal pattern composition including a conductive metal or a conductive metal precursor compound, and a carboxylic acid-amine base ion pair salt.
Abstract:
A golf bag for preventing golf clubs from being misplaced and/or the heads of the golf clubs from being damaged is provided. The golf bag includes a body which can store golf clubs inside and which has a number attachment and detachment areas so that one or more golf club number tags can be attached and detached, multiple golf club number tags that are marked with golf club numbers that can be attached to and detached from the number tag attachment and detachment area, multiple club head covers that cover golf club heads and multiple head cover connectors to connect the golf club number tags to the club head covers. By enabling number tags to be attached to and detached from the golf clubs stored in the golf bag and by connecting the golf club number tags and club head covers, the golf bag can prevent golf clubs from being misplaced as well as protects golf club heads
Abstract:
An apparatus and method for antenna matching according to a position and an angle of a portable terminal is provided. Operations of the portable terminal include, when at least one of a position and an angle of the portable terminal is changed, determining an optimal Tunable Matching Network (TMN) set value corresponding to the position and the angle, and performing antenna matching according to the optimal TMN set value.
Abstract:
A multiband built-in antenna of a portable terminal is provided. The multiband built-in antenna includes a main board having a ground area and a non-ground area on a front surface and an opposite surface, and an antenna radiator having a specific pattern directly formed on the non-ground area of the main board, wherein the antenna radiator comprises a first antenna radiator of which one end is branched off into two parts on the front surface of the main board so that one part is used for feeding and the other part is electrically connected to the ground area, and of which the other end is extended by a specific length in a widthwise direction of the terminal, and a second antenna radiator which protrudes towards the opposite surface of the main board from the other end of the first antenna radiator and is formed in a specific pattern in the non-ground area on the opposite surface of the main board.
Abstract:
A speaker device for a portable terminal is provided. The device includes a case frame forming an exterior of the portable terminal, a speaker installation space provided at an inner surface of the case frame to install a speaker therein, a barrier wall formed to provide a resonance space near the speaker installation space, and a cover installed to seal the resonance space.
