  • Patent number: 8207973
    Abstract: An electronic device is disclosed. The electronic device comprises a transmitter, a converter, and a receiver. The transmitter transmits data and a control signal. The converter receives the control signal from the transmitter and converts the control signal. The receiver receives the data from the transmitter via a data bus isolated from the converter and receives the converted control signal from the converter. The data transmitted from the transmitter is directly electrically connected to the receiver.

  • Patent number: 8194146
    Abstract: An apparatus for capturing and storing real-time images is provided. A camera module records frames corresponding to sensed light, outputs pixel data of the frames on a data bus, and generates synchronization control signals to control the synchronized transmission of the frames. An interrupt controller receives the synchronization control signals and correspondingly generates interrupt signals. A processing unit receives the interrupt signals, fetches the pixel data of the frames on the data bus according to at least one of the interrupt signals, and stores the fetched pixel data in a memory device.

  • Patent number: 8117202
    Abstract: A facility for identifying users that have an interest in a selected subject is described. For each of a number of actual users, the facility establishes a user behavior record describing the behavior of the actual user. The facility also establishes a user behavior record describing behavior of a virtual user. The behavior described by the user behavior record for the virtual user is made up of actions each tending to indicate an interest in the selected subject. The facility identifies a proper subset of the actual users whose user behavior records are most similar to the user behavior record of the virtual user as interested in the selected subject.

  • Patent number: 8107754
    Abstract: An embodiment of a method for encoding a source image comprising multiple data units, performed by an image encoding unit, comprises the following steps. A quantized DC coefficient and multiple AC coefficients of a data unit are generated. A value at the (0,0) element of the first data unit is determined according to the quantized DC coefficient. A variable length coding (VLC) stream of the data unit is generated by encoding the determined value and the AC coefficients. An encoded bitstream comprising a restart mark followed by the VLC stream of the data unit is generated. An offset pointing to the beginning of the restart mark of the encoded bitstream is stored in a random access table. A compression image comprising the encoded bitstream and the random access table is generated.
