  • Patent number: 11635359
    Abstract: An instrument and method for mechanical properties in situ testing of materials under a high temperature and complex mechanical loads are provided. The instrument includes: a support frame module used to provide a stable support and an effective vibration isolation for each functional module of the instrument; a high-frequency fatigue load applying module used to apply a high-frequency fatigue load on a tested sample; a static-dynamic mechanical load applying module used to apply a combination of static-dynamic tension/compression/bending loads on the tested sample; a high/low temperature applying module used to apply a variable temperature environment from a low temperature to a high temperature on the tested sample; and an in-situ monitoring module that may integrate a surface deformation damage measurement assembly, a three-dimensional strain measurement assembly, a microstructure measurement assembly, and an internal damage detection assembly according to a practical testing requirement.

  • 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: 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.
