    • Disclosed is a dehumidifying cooling device for district heating which comprises; a case having a first partition to divide the interior of the case into a wet channel and a dry channel and a second partition to divided the wet channel into a first wet channel and a second wet channel, a sensible heat exchanger to heat exchange the outside air in the first wet channel with the outside air in the second wet channel, a heating coil for raising the temperature of the outside air in the second wet channel, a rotatable de humidifying wheel for adsorbing and removing moisture contained in the circulated air within the dry channel, and a regenerative-evaporative cooler for cooling the circulated air in the dry channel. With this configuration, the device can carry out an air cooling operation by use of hot water supplied by district heating systems and gas or oil boilers installed in individual households, thereby achieving a reduced device size via the implementation of the cooling operation under the atmospheric pressure state and reducing manufacturing costs by virtue of a simplified system configuration.

    • A memory device has a global input/output line pair configured for data transfer. The memory device includes a sense amplifier, a detecting unit and a detect control signal generating unit. The sense amplifier is coupled to the global input/output line pair. The detecting unit detects a potential difference between the global input/output line pair. The detect control signal generating unit disables an operation of the sense amplifier and precharges the global input/output line pair to a predetermined voltage. A precharge operation of a memory device may be performed at a higher speed so that a high speed operation of the memory device may be achieved. In addition, the operating time of the sense amplifier may be decreased so that the power consumption of the memory device may be reduced.

    • A method of controlling a Forward Error Correction (FEC) operation including: configuring a FEC frame to be transmitted between an OLT and an ONU comprising a FEC frame identifier indicating whether FEC should be performed, data, a first flag indicating that FEC should be performed, and a second flag indicating that the FEC frame is to be FEC encoded; initializing the OLT by disabling a FEC function; determining whether the ONU requires FEC to be performed based on a FEC frame identifier received from the ONU; IPG stretching the FEC frame when the ONU requires to FEC to be performed; and transmitting the FEC frame to the ONU after FEC encoding based on the second flag of an input frame to a PCS sublayer from an upper layer. The method controls an effective operation of a FEC of an ONU and an OLT without changing a Round Trip Time (RTT) according to optical link quality in an EPON. Accordingly, FEC is used only if necessary, thereby simplifying the managing of a link, and preventing an excessive 35% reduction of throughput caused by use of unnecessary FEC.
    • 一种控制前向纠错(FEC)操作的方法,包括:配置要在OLT和ONU之间传输的FEC帧,包括指示是否应执行FEC的FEC帧标识符,数据,指示应执行FEC的第一标志 以及指示FEC帧要被FEC编码的第二标志; 通过禁用FEC功能来初始化OLT; 基于从ONU接收到的FEC帧标识来确定ONU是否需要执行FEC; 当ONU需要执行FEC时,IPG扩展FEC帧; 并且基于来自上层的PCS子层的基于输入帧的第二标志的FEC编码之后将FEC帧发送到ONU。 该方法根据EPON中的光链路质量来控制ONU和OLT的FEC的有效操作,而不改变往返时间(RTT)。 因此,仅在必要时使用FEC,从而简化链路的管理,并且防止由于使用不必要的FEC导致的吞吐量的过度的35%的降低。
