Abstract: Operating an NFC device to communicate with an NFC tag may include converting the NFC device between operating in a standby mode or an active mode, based on whether communication between the NFC device and an NFC tag is failed while the NFC device is operating in an active mode, detecting an NFC tag based on a tag detection sensitivity associated with the NFC device operating in the standby mode, converting the NFC device to operating in the active mode when an NFC tag is detected in the standby mode and adaptively controlling the tag detection sensitivity based on one or more user environment parameters associated with the NFC device. Power consumption and the tag detection sensitivity may be optimized based on adaptively controlling the tag detection sensitivity based on the one or more user environment parameters.

Abstract: A device that may implement a video encoder may include generating a video display that includes groups of encoded pictures selected based on comparisons between different groups of encoded pictures that are generated according to separate, independent encoding schemes. Input pictures may include multiple subgroups of one or more input pictures. Each subgroup of pictures may be encoded multiple times, according to separate, independent encoding schemes to generate multiple candidate encoded groups associated with each subgroup. For each subgroup, one candidate encoded group may be selected as encoded pictures associated with the subgroup. The selected encoded pictures may be used to generate a video display that includes the encoded pictures associated with the plurality of subgroups.

Abstract: A washing machine may include a washing tub that is capable of improving washing effect. The washing machine includes: a casing; a washing tub installed in the casing; a plurality of concave sides formed to be recessed into an inner side surface of the washing tub; and a plurality of protrusions that protrude in an inward direction of the washing tub and include a plurality of first protrusions formed on the plurality of concave sides. A frictional force with laundry is generated using a washing tub including the plurality of protrusions and the plurality of concave sides so that a washing force can be enhanced and a flow of washing water can be guided.

Abstract: The inconvenience associated with using a lower basket of a dish washing machine is reduced or eliminated by a dish washing machine which includes a washing tub with an open front, a basket configured to be inserted in or drawn out from the washing tub through the open front of the washing tub, a door which opens or closes the open front of the washing tub, at least one guide rail for mounting the basket on the door when the basket is drawn out from the washing tub while the door is open, and a lifting device which guides the guide rail to move between a raised position and a lowered position of the guide rail.

Abstract: An apparatus for growing a silicon single crystal according to embodiments includes a chamber including a crucible accommodating silicon melt; a support shaft rotating and lifting the crucible while supporting the crucible; a main heater part for applying heat to the crucible side, the heater disposed beside the crucible; an upper heat insulation member located over the crucible; and upper heater parts located at a lower end portion of the upper heat insulation member, wherein the upper heater parts have diameters different from each other with respect to a center of the crucible, and include a plurality of ring-shaped heaters which are spaced apart from each other. Due to the individually controllable upper heater parts, a uniform thermal environment can be provided for silicon melt accommodated in a crucible, and localized solidification of the silicon melt can be prevented so that the quality of a silicon single crystal and the ingot pulling speed can be readily controlled.

Abstract: Provided is a coupling structure for easy installation and separation of a faucet. The coupling structure includes a connection body which is connected to a water supply pipe at one side and has a coupler at an opposite side. A connection pipe formed in the faucet is fitted to the coupler such that the faucet is coupled to the connection body to allow the faucet to be supplied with water and to discharge the water. A grab ring is formed in the coupler, and an actuation ring is installed in the connection pipe so as to be moved forward and backward. When the actuation ring is moved forward, the actuation ring expands the grab ring to allow the connection pipe to be separated from the coupler. Easy installation of the faucet enhances convenience in construction. Easy separation of the faucet, when necessary, enhances convenience in maintenance.

Abstract: Disclosed herein is a washing machine that includes a tub disposed in a main body of the washing machine to store water. A circulation apparatus includes a circulation pump operable to circulate the water in and out of the tub. A detergent supply apparatus is coupled to the circulation apparatus to discharge detergent to the circulation apparatus so that operation of the circulation pump causes the discharged detergent to be supplied to the tub.

Abstract: An organic light emitting diode includes an anode; a cathode facing the anode; a first emitting material layer between the anode and the cathode and including a first host material, the first host material having a first triplet energy; and a hole transporting layer between the first emitting material layer and the anode, a material of the hole transporting layer having a second triplet energy being larger than the first triplet energy.

Abstract: A washing machine includes a cabinet having an opening, a door to open and close the opening, and a locking unit to selectively restrict an operation of the door when the door is closed. A position of the door is adjusted through this configuration to stably close the opening and to prevent the door from being undesirably opened, and thus it is possible to improve washing efficiency. Further, a front structure of the opening may be improved, and thus laundry may be easily put in or taken out.

Abstract: A door hinge apparatus having a coupling structure between a door and a cabinet, and a drum-type washing machine having the same. The drum type washing machine includes an inlet formed through the cabinet to allow laundry to be inserted or withdrawn therethrough, a door coupled to the cabinet to open and close the inlet, and a hinge between the door and the cabinet. The hinge includes a cabinet bracket coupled to a front surface of the cabinet, a door bracket coupled to the door, a first moving unit coupled to the door bracket to allow the door to be pivoted with respect to the cabinet, and a second moving unit coupled to the cabinet bracket to allow the door to protrude forward from the cabinet and be substantially parallel and spaced from the cabinet.
