Abstract: A display apparatus, a power supply apparatus and a power supply method are provided. The display apparatus display apparatus includes: a signal receiving unit which receives an image signal; a signal processing unit which processes the image signal; a display unit which displays an image based on the image signal processed by the signal processing unit; and a power supply unit which receives AC power and supplies operation power to the display unit. The power supply unit includes a discharging circuit part which includes a discharging element which discharges the power supply unit to remove a residual voltage from the power supply unit when the AC power is suspended, the discharging circuit part preventing the discharging element from consuming power when the AC power is input. It is possible to minimize wasteful power consumption caused by a discharging element provided to guarantee user's safety against a residual voltage.

Abstract: Disclosed is an electrochemical device comprising a cathode having a complex formed between a surface of a cathode active material and an aliphatic di-nitrile compound; and a non-aqueous electrolyte containing 1-10 wt % of a compound of Formula 1 or its decomposition product based on the weight of the electrolyte.

Abstract: Provided is a terminal and an access point in an active mode for multi-user transmission opportunity (TXOP) power saving that may decrease power consumption by changing an operation state of the terminal from an awake state to a sleep state if there is no stream of data to be transmitted during a TXOP duration.

Abstract: Provided is a communication system using a space division multi-user multiple input multiple output (SD-MIMO) communication method. A transmission apparatus may transmit, to each of terminals included within a coverage, common control information commonly transmitted to the terminals and individual control information individually transmitted to each of the terminals. The transmission apparatus does not precode the common control information and transmits the non-precoded common control information. The transmission apparatus precodes the individual control information and transmits the precoded individual control information.

Abstract: A display apparatus is provided. The display apparatus includes a display panel which displays an image, a LED module which provides backlight to the display panel, a LED driving unit which selectively uses current of an inductor to apply driving voltage to the LED module, a sensing unit which senses a current value of the inductor, and a switching control unit which adjusts the driving voltage according to sensing result by the sensing unit.

Abstract: A radiation imaging device capable of matter-element information acquisition and image based selection comprises: a radiation source generating radiation; at least one scattering device receiving radiation which includes radiation transmitting a subject and scattered radiation and scattering the received radiation; and an imaging device receiving the radiation which includes the radiation transmitting the subject and the scattered radiation to measure energy and positional information so as to calculate a two-dimensional image.

Abstract: Disclosed is an electrochemical device comprising a cathode having a complex formed between a surface of a cathode active material and an aliphatic di-nitrile compound; and a non-aqueous electrolyte containing 1-10 wt % of a compound of Formula 1 or its decomposition product based on the weight of the electrolyte.

Abstract: Disclosed is a system for reducing a heating value of natural gas. The system includes a heat exchanger to liquefy a portion of components having high heating values, a gas-liquid separator to separate the liquefied component, and a nitrogen adding mechanism to add nitrogen to remaining non-liquefied components. The system includes an additional heat exchanger to cool and liquefy the remaining non-liquefied components after the gas-liquid separator separates the liquefied component from the natural gas. The heat exchangers employ cold heat generated upon regasification of LNG. The system can reduce the heating value of natural gas composed of a variety of hydrocarbon components according to requirements of a place of demand by separating the component with the higher heating value from the natural gas to allow the separated component to be used as fuel, thereby reducing an overall size and operating costs of the system.

Abstract: A flexible sleeve includes a first flexible sheet of a first hardness. The first flexible sheet has a first perimeter including a first lip edge and a first pocket edge. The flexible sleeve also includes a second flexible sheet of a second hardness, different than the first hardness. The second flexible sheet has a second perimeter including a second lip edge and a second pocket edge. The second pocket edge is joined to the first pocket edge, and the second lip edge is free from the first lip edge so that the first flexible sheet and the second flexible sheet collectively form a pocket having a mouth defined by the first lip edge and the second lip edge. The flexible sleeve further includes a connector joined to the mouth and configured to mate the mouth to a head of a device while the pocket substantially covers a tail of the device.

Abstract: An apparatus and method for transmitting packets in a communication system. The packet transmission method for the communication system includes the steps of a) receiving Quality of Service (QoS) information and data rate information from an upper layer, b) receiving channel status information of wireless stations from a lower layer, and c) creating an aggregation packet according to the received information, and transmitting the created aggregation packet to a Media Access Control (MAC) layer.

Abstract: Provided is a communication method of a reception apparatus and a transmission apparatus that may decrease consumption of power by changing an operation state of a corresponding reception apparatus from an awake state to a sleep state when a stream to be transmitted is absent during all or a portion of a transmission opportunity (TXOP).

Abstract: A home appliance and a home appliance system are provided. The home appliance receives input of a sound including update information, and updates a product operating program. The home appliance system receives a sound including product information from the home appliance, judges whether to update the product operating program of the home appliance, and transmits update information.

Abstract: In the data transmission method, a MAC layer receives data from an upper layer, classifies the data according to destination addresses and traffic identifiers, aggregates the data by destination address and traffic identifier as a first transmission unit, aggregates the first transmission units having the identical destination address as a second transmission unit, and transmits the second transmission units having different destination addresses in a single frame. The data transmission method allows packets transferred from the upper layer to be hierarchically aggregated by DAs and TIDs and then packaged into a data unit for each destination such that it is possible to transmit the data at an optimal data rate for each destination terminal.
