  • Patent number: 8884869
    Abstract: A court border module using a display apparatus is disclosed, which uses piezoelectric elements to drive the display apparatus. When a ball hits a court border, which is defined by the display apparatus, a force is applied to the piezoelectric elements which then generate power to drive the corresponding part of the display apparatus. The color of the part of the display apparatus hit by the ball is switched. Therefore the change in the color of the court border can be observed by officials and others to instantly and objectively determine whether the ball has hit the court border.

  • Publication number: 20140254193
    Abstract: An optical substrate having a structured light output surface that comprises rows of laterally arranged snaking, wavy or meandering longitudinal prism structures. The prism structures at the light output surface may be viewed as comprising rows of laterally meandering longitudinal prisms and/or sections of curved segments coupled end-to-end to form the overall meandering longitudinal prism structures. The laterally meandering rows of longitudinal prism structures are arranged in parallel laterally (side-by-side), defining parallel peaks and valleys (a facet is defined between each adjacent peak and valley). In one embodiment, the lateral waviness is regular with a constant or variable wavelength and/or wave amplitude (or extent of lateral deformation). The lateral waviness may generally follow a sinusoidal profile, or other curved profile.
