  • Patent number: 8265575
    Abstract: A communication apparatus is provided. A power amplifier is coupled to an antenna and switched on or off according to a control signal. A baseband processing module is coupled to the power amplifier and a radio transceiver module, receives a bit stream comprising information indicating corresponding transmitting time and sub-carrier frequencies of up-link messages via the radio transceiver module, processes the bit stream to obtain a map profiling allocations of the up-link messages, prepares the up-link messages to be transmitted according to the map, and generates the control signal according to the map. Within a data frame period, when there is no up-link message to be transmitted during a up-link time interval, the power amplifier is switched off in response to the control signal during the up-link time interval.

  • 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.
