  • Patent number: 10083710
    Abstract: A voice control system including a voice receiving unit, an image capturing unit, a storage unit and a control unit is disclosed. The voice receiving unit receives a voice. The image capturing unit captures a video image stream including several human face images. The storage unit stores the voice and the video image stream. The control unit is electrically connected to the voice receiving unit, the image capturing unit and the storage unit. The control unit detects a feature of a human face from the human face images, defines a mouth motion detection region from the feature of the human face, and generates a control signal according to a variation of the mouth motion detection region and a variation of the voice over time. A voice control method, a computer program product and a computer readable medium are also disclosed.

  • Patent number: 9578604
    Abstract: A power-allocation method for scalable video transmission over MIMO system includes: encoding a video sequence into L layers; performing MCSs to the layers and estimating bit error rate or symbol error rate respectively for each of the layers after MCSs procedure based on channel quality feedbacks from the receiver side; performing power allocations of L sub-problems and obtaining candidate power allocation solution of each of the sub-problems respectively based on bit error rate or symbol error rate of each of the layers and derivative of bit error rate or symbol error rate of each of the layers; and choosing one of the candidate power allocation solution with the largest quality of experiences as the power allocation of the scalable video transmission over MIMO system. This invention considers transmission-error-rate of PHY layer and video coding structure of APP layer and optimizes quality of experiences at user end with cross-layer design.

  • Patent number: 9118362
    Abstract: A system for selecting a transmission mode under the multi-input multi-output (MIMO) architecture based on a scheduling number and a method thereof are provided. A modulation coding of the spatial diversity (SD) mode and the spatial multiplexing (SM) mode according to channel state information sent from client ends is determined, respectively. The SD mode or the SM mode is selected in accordance with a scheduling number of using the SD mode and a scheduling number of using the SM mode, respectively. The transmission mode is selected based on the spectrum utilization and the scheduling rate, which achieves improving the spectrum utilization on the premise of the scheduling rate.

  • Patent number: 8971177
    Abstract: An event trigger and management system for providing automatic repeat requests (ARQs) by a single timer and a method thereof are provided. Various type timers for providing an ARQ are integrated into a single timer. Through a data structure of a timer node of automatic repeat requests time series, the automatic repeat request time series can be managed only by a single timer. Therefore, the efficiency of controlling and managing a timer associated with Worldwide Interoperability for Microwave Access (WiMAX) may be achieved.

  • Publication number: 20090233002
    Abstract: A method of an anti-glare surface treatment including following steps is provided. First, a resin layer is formed on a substrate. Next, the substrate is placed in a chamber that is filled with a water steam. A number of micro cavities are formed on a surface of the resin layer on the substrate by means of collision of the water steam. The resin layer on the substrate is then cured. The above-mentioned method of the anti-glare surface treatment is easy in process, low in cost and good in quality control.
