    • A scanner includes a first illuminant device having a first power associated therewith, and a second illuminant device having a second power associated therewith. The first power is greater than the second power, and each of the first illuminant device and the second illuminant device is configured to selectively scan a document. The scanner is configured to select one of the first illuminant device and the second illuminant device based, at least in part on, a level of power supplied to the scanner via a power source, and perform a single scan of the document using only the selected one of the first illuminant device and the second illuminant device.

    • In accordance with the present invention, a method and a system for promoting scanning speed are provided. The method comprises steps of determining a transmission rate of a transit interface, adjusting system clock responsive to the transmission rate of the transit interface to change a data generated rate, and scanning an original to generate data at the rate controlled by the system clock. The key aspect of the present invention is by adjusting system clock to change the data generated rate corresponding to the transmission rate of the transit interface. Therefore, in response to the transmission rate of the transit interface, the system clock is adjusted to produce the data at a rate that can reduce the possibility of memory buffer full leading to the reduction in the time wasting on start-stop processes and therefore promote the scanning speed without requiring the increase in size of a memory buffer.
    • 根据本发明,提供了一种用于促进扫描速度的方法和系统。 该方法包括以下步骤:确定传输接口的传输速率,响应于传输接口的传输速率调整系统时钟以改变数据产生速率,以及扫描原件以由系统时钟控制的速率生成数据。 本发明的关键方面是通过调整系统时钟来改变与传输接口的传输速率相对应的数据产生速率。 因此,响应于传输接口的传输速率,系统时钟被调整以产生数据,其速率可以降低存储缓冲器的可能性,从而导致在启动停止处理上浪费的时间减少,从而促进 扫描速度,而不需要增加存储器缓冲器的大小。

    • An injection-locked frequency divider (ILFD) including a signal injector, an oscillator (OSC), and a buffer stage is provided. The signal injector is configured for receiving an injection signal. The OSC is configured for dividing the frequency of the injection signal, so as to generate a first divided frequency signal, where there is an integral-multiple relation between the frequency of the first divided frequency signal and that of the injection signal. The buffer stage is configured for receiving and boosting the first divided frequency signal, and performing a push-push process on the first divided frequency signal, so as to output a second divided frequency signal, where there is a fractional-multiple relation between the frequency of the second divided frequency signal and that of the injection signal.
    • 提供了包括信号注入器,振荡器(OSC)和缓冲器级的注入锁定分频器(ILFD)。 信号注射器被配置为接收注入信号。 OSC被配置为用于分割喷射信号的频率,以便产生第一分频信号,其中在第一分频信号的频率与喷射信号的频率之间存在整数倍关系。 缓冲级被配置为接收和升压第一分频信号,并且对第一分频信号执行推推处理,以便输出第二分频信号,其中频率之间存在小数倍关系 的第二分频信号和注入信号的信号。
