    • PURPOSE: An apparatus and a method for optimizing a DC/DC converter using a genetic algorithm are provided to maximize the efficiency by selecting an efficient element under a predetermined operation condition. CONSTITUTION: An apparatus for optimizing a DC/DC converter using a genetic algorithm includes an optimization unit and a time calculation unit. The optimization unit(10) changes a predetermined value of a DC/DC converter by using a period of time and the genetic algorithm. In addition, the optimization unit outputs a changed value. The time calculation unit(20) receives the changed value from the optimization unit, calculates an expectation time, and the calculated result to the optimization unit.
    • 目的:提供使用遗传算法优化DC / DC转换器的装置和方法,以通过在预定操作条件下选择有效元件来最大化效率。 构成:使用遗传算法优化DC / DC转换器的装置包括优化单元和时间计算单元。 优化单元(10)通过使用一段时间和遗传算法来改变DC / DC转换器的预定值。 此外,优化单元输出改变的值。 时间计算单元(20)从优化单元接收改变的值,计算期望时间,并将计算结果计算到优化单元。

    • PURPOSE: An apparatus and method for interfacing a home gateway with a TV are provided to use the TV as a display device of the home gateway without an additional terminal. CONSTITUTION: An apparatus for interfacing a home gateway with a TV includes a wireless keyboard(10), a home gateway(20), and a TV(30). The wireless keyboard receives a key signal from a user, encodes the key signal and modulates the encoded signal into an infrared signal through an infrared port. The home gateway receives the infrared signal from the wireless keyboard through an asynchronous transceiver to decode the signal, encodes the decoded signal to match the signal with a control signal of the TV, and output the signal through the asynchronous transceiver. The TV receives the infrared signal from the home gateway to convert its mode and displays a composite video signal and audio signal output from a video output unit and an audio output unit of the home gateway.
    • 目的:提供一种用于将家庭网关与电视接口连接的设备和方法,以将电视用作家庭网关的显示设备而无需额外的终端。 用于连接家庭网关与电视的装置包括无线键盘(10),家庭网关(20)和电视机(30)。 无线键盘接收来自用户的键信号,对键信号进行编码并通过红外端口将编码信号调制成红外信号。 家庭网关通过异步收发器接收来自无线键盘的红外信号,对信号进行解码,对解码后的信号进行编码,使信号与电视机的控制信号相匹配,并通过异步收发器输出。 电视接收来自家庭网关的红外信号以转换其模式,并显示从家庭网关的视频输出单元和音频输出单元输出的复合视频信号和音频信号。
