    • A wide image scanner which can scan the image of a large scale original using only a regular image sensor is provided. The invention includes a sliding shaft, an image reading device, a number of paper width sensors, a paper edge sensor, and a control module. Whenever the paper edge sensor detects the presence of an end edge of the original, it will send a vertical control signal to the control module to control the rotation direction of the rollers. On the other hand, the paper width sensors detect the width of the original and send the horizontal control signals to the control module. From the horizontal control signals, the control module can determine the number of horizontal displacement positions and control the horizontal displacement each time for the image reading device after the paper edge sensor detects the end edge of the original. The procedure continues until the image reading device has been moved to the final displacement position predetermined by the horizontal control signal. Consequently, the entire image of the origin can automatically be read portion by portion without manual operation.
    • 提供了可以仅使用常规图像传感器来扫描大尺寸原稿的图像的宽幅图像扫描仪。 本发明包括滑动轴,图像读取装置,多个纸张宽度传感器,纸张边缘传感器和控制模块。 每当纸张边缘传感器检测到原稿的端部边缘时,它将向控制模块发送垂直控制信号,以控制滚轮的旋转方向。 另一方面,纸张宽度传感器检测原稿的宽度,并将水平控制信号发送到控制模块。 从水平控制信号,控制模块可以确定水平位移位置的数量,并且在纸张边缘传感器检测到原稿的端边缘之后,每次对图像读取装置控制水平位移。 该过程继续,直到图像读取装置已经移动到由水平控制信号预定的最终位移位置。 因此,原点的整个图像可以自动地逐个读取,而无需手动操作。

    • A wireless local area network (WLAN) transceiving integrated circuit includes a WLAN interface, an input buffer, an input buffer controller, and a processor. The WLAN transceiving integrated circuit may also include an output buffer, an output buffer controller, a transcoder, and/or an audio Coder-Decoder (CODEC). The WLAN transceiving integrated circuit is installed in a WLAN device that services voice communications. The input buffer receives packetized audio data from the WLAN interface. When the input buffer satisfies a buffer vacancy threshold, the processor and the input buffer controller cooperatively operate to fill at least a portion of the input buffer with packetized audio data. The processor copies packetized audio data from the input buffer and fills the input buffer with the copied packetized audio data to maintain an audio pattern in the input buffer. The input buffer controller fills the input buffer when the processor is available and after copying/filling is no longer effective. The processor operates to maintain the audio pattern when additional packetized audio data is received by the WLAN interface. These operations are also performed for the output buffer, which receives packetized audio data from the transcoder and writes the packetized audio data to the WLAN interface.
    • 无线局域网(WLAN)收发集成电路包括WLAN接口,输入缓冲器,输入缓冲器控制器和处理器。 WLAN收发集成电路还可以包括输出缓冲器,输出缓冲器控制器,代码转换器和/或音频编解码器(CODEC)。 WLAN收发集成电路安装在服务语音通信的WLAN设备中。 输入缓冲区从WLAN接口接收分组化音频数据。 当输入缓冲器满足缓冲空缺阈值时,处理器和输入缓冲器控制器协同工作,以便用分组化音频数据填充输入缓冲器的至少一部分。 处理器从输入缓冲器复制分组化的音频数据,并用复制的分组化音频数据填充输入缓冲器,以保持输入缓冲器中的音频模式。 当处理器可用并且复制/填充不再有效之后,输入缓冲器控制器填充输入缓冲器。 当附加的分组化音频数据被WLAN接口接收时,处理器操作以维持音频模式。 这些操作也对输出缓冲器执行,输出缓冲器从代码转换器接收打包的音频数据,并将打包的音频数据写入WLAN接口。
