  • Publication number: 20240068124
    Abstract: An apparatus for producing silicon carbide crystal is provided and includes a composite structure formed by a plurality of graphite layers and silicon carbide seed crystals, wherein a density or thickness of each layer of graphite is gradually adjusted to reduce a difference of a thermal expansion coefficient and Young's modulus between the graphite layers and silicon carbide. The composite structure can be stabilized on a top portion or an upper cover of a crucible made of graphite, thereby preventing the silicon carbide crystal from falling off.

  • Patent number: 9246380
    Abstract: A control circuit module for a power factor corrector is provided to convert the operation mode of the inductor current from the boundary conduction mode (BCM) to the discontinuous conduction mode (DCM) when a transistor element is operated under the valley inductor current, thus reducing the switching frequency and increasing system efficiency, also to maintain the operation mode of the inductor current in the BCM when the transistor element is operated under the peak inductor current, thus maintaining system efficiency.

  • Patent number: 9116549
    Abstract: An electronic device having an input control application is disclosed. The input control application is used for enabling the electronic device to execute the following actions: obtaining a member group comprising members lined up orderly and a member as a selection member; pressing a key to generate a first signal for excluding members after the selection member, then determining if only one member left in the member group, if “No”, determining the member of the member group in the middle as the new selection member, if “Yes”, executing the input operation; pressing another key to generate a second signal for excluding the members before the current selection member, then determining if only one last member in the current member group, if No”, determining the member of the member group in the middle as the new selection member, if “Yes”, executing the input operation.

  • Publication number: 20120287229
    Abstract: A method for generating a video output signal that may receive a plurality of input video signals from a number of participants. The input video signals may have a plurality of input frames. The video output signal may comprise a plurality of output frames. A first of the output frames generally has at least a first slice having (a) a first coded portion carrying the image from a first of the participants and (b) a first unencoded portion for the image from a second of the participants. A second of the output frames generally has at least a second slice having (a) a second coded portion carrying the image from the second participant and (b) a second unencoded portion for the image from the first participant. The frames of the video output signal are generated as soon as one of the frames of the video input signal are received.

  • Patent number: 8164618
    Abstract: A method for generating a video output signal. The method may include receiving a plurality of input video signals from each of the participants. Each of the input video signals may have a plurality of input frames. Each of the input frames may have a source slice carrying an image. Each of the input frames may be encoded using the respective reference frame at an encoding time. The method may include a step for generating the video output signal for transmission to the participants. The video output signal may comprise a plurality of output frames. A first of the output frames generally has at least a first slice having (a) a first coded portion carrying the image from a first of the participants and (b) a first unencoded portion for the image from a second of the participants. A second of the output frames generally has at least a second slice having (a) a second coded portion carrying the image from the second participant and (b) a second unencoded portion for the image from the first participant.
