  • Publication number: 20090315923
    Abstract: A display method of images in electronic paper panel includes: set the resolution for display; add a new event which indicates and drives the new image display; trim the new image to fit in with the resolution; compress the image when it needs to be stored, only reserve the mean values of pixels within each column and each row, as the character of the image; compare the next image with the present image and get the correlation coefficient of the two images; according to the correlation coefficient, set a proper display mode; enhance the image based on human visual character, and then display image. This invention extends the application of electronic paper to intelligent operating system areas, and it is easy to be ported to different advanced intelligent operating systems. It can significantly eliminate the ghosting and flicker on the electronic paper panel, and it also reduces the power consumption of the electronic paper systems and reduces the response time for display.

  • Publication number: 20090315901
    Abstract: A updating method of images in electronic paper panel includes: divide the screen and image into (N*N) areas and build indexes for them; compare the present image on the display screen with the next image and compute the different areas; according to the computing result, find the uppermost, undermost, leftmost and rightmost different areas and compute the area of the smallest rectangle which includes the different areas; compare the result with the configured threshold and according to this compared result, set up the updating method to display the image. This method effectively reduces the data of updating images and save the power of the electronic paper, especially the power of the electronic paper panel. It can also improve the response time of the electronic paper panel. At the same time, it is easy to be ported to other advanced embedded operating systems. Thus, it could provide an effective method for the products related to the electronic paper.

  • Publication number: 20020133613
    Abstract: A customer premises gateway including a traffic analyzer with usage tracking to detect fraud such as in the case of masquerading by a router attached to the gateway, and a head-end server including fraud detection and a billing system for providing a maximum bandwidth specifier to the gateway. In the case of Internet Protocol, the traffic and fraud analysis may utilize the address:port combination and also the traffic type specifier to detect fraud and masquerading and to control bandwidth.
