    • A system and method for processing postal work using Radio Frequency Identification (RFID) apparatus. With RFID applied to the postal work, the system includes a structure for managing postal devices used in postal registration center and postal delivery center such as embedded controllers for controlling monitors, audio alarms, alarm lamps and PDAs. The system also includes middleware for managing RFID readers and message repeater adopting Java Messaging Service (JMS) . This allows exchanging data received from the RFID reader by JMS transfer method, ensuring stable asynchronous exchange of information and effective monitoring of data transferred in an entire process of postal work. This also decreases the load of the middleware in a work environment where a large amount of data is received in a short period of time such as postal work process.
    • 一种使用射频识别(RFID)设备处理邮政工作的系统和方法。 随着RFID应用于邮政工作,该系统包括用于管理在邮政注册中心和邮政递送中心使用的邮政设备的结构,例如用于控制监视器,音频警报,报警灯和PDA的嵌入式控制器。 该系统还包括管理RFID阅读器的中间件和采用Java消息服务(JMS)的消息中继器。 这样可以通过JMS传输方式交换从RFID阅读器接收到的数据,确保信息的稳定的异步交换和对整个邮政工作过程中传输的数据的有效监控。 这也减少了在诸如邮政工作过程的短时间内接收到大量数据的工作环境中的中间件的负载。

    • Disclosed is an apparatus and method for preventing liquid refrigerant accumulation in an accumulator of an outdoor unit of an air conditioner. The method includes the steps of: determining a state of a compressor; if the compressor is in standby mode or off state, turning on a four-way valve; determining whether the state of the compressor in standby mode or off state continues longer than a predetermined amount of time; and if the state of the compressor continues longer than the predetermined amount of time, closing an expansion valve. Particularly, high-pressure refrigerant flows in the closed expansion valve while low-pressure refrigerant flows in a check valve through the four-way valve. The apparatus includes a suction pipe connected to spray oil of the accumulator to the compressor; a liquid recovery pipe with one end being connected to the suction pipe and the other end being connected to the accumulator; and a liquid recovery valve for controlling opening/closing of the liquid recovery pipe, in which a compressor of the air conditioner in cooling or heating mode is operated and a liquid recovery valve for controlling a liquid recovery pipe connected to the compressor and an accumulator is opened to reduce oil in the accumulator. According to the present invention, when the compressor is off, it is possible to prevent liquid refrigerant accumulation by changing refrigerant flow line to the accumulator and the refrigerant at the lower end of the accumulator can be recovered.
    • 公开了一种用于防止液体制冷剂积聚在空调的室外机的蓄能器中的装置和方法。 该方法包括以下步骤:确定压缩机的状态; 如果压缩机处于待机模式或关闭状态,打开四通阀; 确定压缩机的状态是否处于待机模式或关闭状态持续时间超过预定时间量; 并且如果压缩机的状态继续长于预定时间量,则关闭膨胀阀。 特别地,高压制冷剂在闭合膨胀阀中流动,而低压制冷剂通过四通阀在止回阀中流动。 该设备包括一个连接到压缩机上的蓄能器喷油的抽吸管; 液体回收管,其一端连接到吸入管,另一端连接到蓄能器; 以及用于控制液体回收管的打开/关闭的液体回收阀,其中操作冷却或加热模式的空调的压缩机和用于控制连接到压缩机和蓄液器的液体回收管的液体回收阀 打开以减少蓄能器中的油。 根据本发明,当压缩机关闭时,可以通过改变制冷剂流向蓄能器的流线来防止液体制冷剂的积聚,并且能够回收蓄能器的下端的制冷剂​​。

    • A color reproduction correcting system and method, and a video display device and method can reproduce original color by considering signal source and display device. Each signal source information and each display device information can be stored. The signal source and the display device, which are currently used (e.g., corrected), can be determined, for example, by a user selection. In one embodiment, the signal provided from a transmission side can be inverse gamma-corrected based on a corresponding signal source, and a colorimetric error of the inverse gamma-corrected signal is preferably corrected using corresponding signal source information and display device information. The corrected colorimetric error signal can be gamma-corrected based on a corresponding display device and then can be displayed on the corresponding display device.
