  • Patent number: 8213090
    Abstract: An electrowetting pixel structure includes a substrate, a hydrophobic dielectric layer, a non-polar liquid, a polar liquid, at least one electrode, and at least one contact hole. The hydrophobic dielectric layer is formed on the substrate, the non-polar liquid covers one surface of the hydrophobic dielectric layer, and the polar liquid is provided on the hydrophobic dielectric layer where the non-polar liquid and the polar liquid are immiscible. The electrode is formed on the substrate and divides the substrate into an electrode section and a non-electrode section. When a voltage is applied to the electrowetting pixel structure, the non-polar liquid contracts on the hydrophobic dielectric layer and is confined to an area substantially overlapping the non-electrode section. The contact hole is formed on the substrate at a position away from the non-electrode section of the electrowetting pixel structure.

    Abstract: Various embodiments of the present invention are directed to external, electronically controllable modulators. In one embodiment, a modulating device (100,400) includes a first electrode (104,404), a second electrode (106,406), and an active region (102,402). The active region is configured so that at least a portion of the active region is disposed between the first electrode and the second electrode. Applying a voltage of an appropriate magnitude and polarity to the electrodes changes the conductivity of the active region which in turn shifts the phase and/or amplitude of electromagnetic radiation transmitted through the active region.

  • Publication number: 20120151002
    Abstract: The present invention is to provide a system including at least one storage device for storing at least one file each having a file name, a home gateway having a routing identification code and connected to the storage device, and a server connected to the home gateway via the Internet for receiving the routing identification code and the file name uploaded by the home gateway. The server stores a user's registration information corresponding to the routing identification code. When a terminal device connected to the server via the Internet uses the registration information to pass the server's verification and thus log in the server, the server transmits the file name to the terminal device and, when receiving a request instruction from the terminal device, then retrieves the file from the storage device by way of the home gateway and then sends the file to the terminal device as requested.
