    • A digital hand stamp that can print multiple images on a supporting surface. The digital hand stamp includes a frame member, an ink jet printing head, a non-volatile memory, an image selection button, a display area, and a printing control circuit. The frame member has a cavity. The ink jet printing head has one or more nozzles. The ink jet printing head can be activated to slide inside the cavity of the frame member when the digital hand stamp is pressed against the supporting surface. The non-volatile memory can store a plurality of images. The image selection button can select an image from the plurality of images stored in the non-volatile memory. The display area can display the image selected by the selection button. The printing control circuit controls the nozzles on the ink jet printing head to project an ink pattern on the supporting surface when the ink jet printing head slides inside the cavity of the frame member. The ink pattern on the supporting surface represents the image selected by the image selection button.
    • 可在支撑面上打印多张图像的数码手印。 数字手印包括框架构件,喷墨打印头,非易失性存储器,图像选择按钮,显示区域和打印控制电路。 框架构件具有空腔。 喷墨打印头具有一个或多个喷嘴。 当数字手印压在支撑表面上时,喷墨打印头可被启动以在框架构件的空腔内滑动。 非易失性存储器可以存储多个图像。 图像选择按钮可以从存储在非易失性存储器中的多个图像中选择图像。 显示区域可以显示通过选择按钮选择的图像。 当喷墨打印头在框架构件的空腔内滑动时,打印控制电路控制喷墨打印头上的喷嘴以在支撑表面上突出墨图案。 支撑表面上的墨水图案表示由图像选择按钮选择的图像。

    • A method and an apparatus for calculating packet arrival time interval are provided by the present invention. In the above-mentioned method, when the current packet arrives, system current time T2 is read from a timer, and the arrival time T1, recorded in an external RAM, of previous packet of the flow to which the current packet belongs is read (301), wherein the timer implements a cycle timing with a period of preset time period Tmax, the preset time period Tmax is larger than or equal to the time for filling the maximum depth of the token bucket of the flow at the minimum token injection rate; a current flag bit, recorded in an internal RAM, of the flow to which the current packet belongs is read (303), wherein the current flag bit is used for indicating the number of cycles of the timer between the system current time T2 and the arrival time T1 of previous packet; and the arrival time interval of the present packet is calculated according to the system current time T2, the arrival time T1 of previous packet and the current flag bit (305). Application of the present invention can reduce the consumption of the internal RAM and improve the operability for realizing by the hardware chips.
    • 本发明提供一种用于计算分组到达时间间隔的方法和装置。 在上述方法中,当当前分组到达时,从定时器读取系统当前时间T2,读取当前分组所属的流的先前分组的记录在外部RAM中的到达时间T1( 301),其中定时器以预设时间段Tmax的周期执行周期定时,预设时间段Tmax大于或等于以最小令牌注入速率填充流的令牌桶的最大深度的时间 ; 读取当前分组所属的流的记录在内部RAM中的当前标志位(303),其中当前标志位用于指示系统当前时间T2和系统当前时间T2之间的定时器的周期数 前一包的到达时间T1; 并根据系统当前时间T2,先前分组的到达时间T1和当前标志位(305)来计算当前分组的到达时间间隔。 本发明的应用可以减少内部RAM的消耗,并提高硬件芯片实现的可操作性。
