  • 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.

  • Publication number: 20060140293
    Abstract: A method for detecting signal and estimating symbol timing is provided. The method is applicable to the receiver in an OFDM system. The method uses the autocorrelation of the short preamble of input signals to detect signals, and performs the coarse frequency offset compensation at the same time. Then, the end of the short preamble for the input signals is detected by the signal detection. The compensated signals are cross-correlated with the portion of the long preamble or that of guard interval together with the long preamble. In addition, the method uses the information for the end of the short preamble to find out a range of the sliding window for estimating symbol timing. In such a manner, the method can make sure of the accuracy for the symbol timing.
