    • An automatic feedback adjustment device for a digital antenna includes a digital antenna unit, a trafficator, a tuner, a demodulator, an antenna direction driver unit, a secondary controller, and a primary controller. The digital antenna unit is a digital video/broadcasting antenna system. The trafficator is connected to the digital antenna unit to retrieve direction data associated with the actual elevation angle and direction. The tuner is connected to the digital antenna unit and the demodulator is connected to the tuner in order to receive and convert a transmission signal from a transmission terminal into the video data and a received-signal quality signal. The antenna direction driver unit is connected to the digital antenna unit in order to drive adjustment of direction and elevation angle of the antenna. The secondary controller is connected to the trafficator, the demodulator and the antenna direction driver unit to receive the data of the actual antenna direction, the video data, and the received-signal quality signal and supplies an antenna drive signal. The primary controller is connected to the Internet, the storage device and secondary controller to retrieve and store the optimum direction and elevation angle for the antenna to receive signals and analyze and calculate data of the optimum signal receiving direction for the secondary controller and the secondary controller drives the antenna direction drive unit to control the digital antenna unit to automatically adjust to the optimum receiving direction.

    • A power-on error detection system and method applicable in an electronic device having a motherboard is proposed, wherein the motherboard is provided with a memory for storing a BIOS program and a signal outputting unit. The power-on error detection system and method are used to indicate an operation state of the electronic device while the electronic device reads the BIOS program at power-on and performs a POST (Power-on self-test) process. A first warning signal output command is set in the a segment of the BIOS program. The first warning signal output command drives the signal outputting unit to output a first warning signal after the electronic device is turned on and executes the POST process according to the BIOS program stored in the memory.
    • 提出了一种适用于具有主板的电子设备的上电错误检测系统和方法,其中主板设置有用于存储BIOS程序和信号输出单元的存储器。 上电错误检测系统和方法用于指示电子设备的操作状态,同时电子设备在通电时读取BIOS程序并执行POST(开机自检)过程。 在BIOS程序的一个段中设置第一个警告信号输出命令。 第一警告信号输出命令驱动信号输出单元在电子设备接通之后输出第一警告信号,并根据存储在存储器中的BIOS程序执行POST处理。
