  • Publication number: 20140024944
    Abstract: Systems and methods for measuring flow velocities, including ultrasound systems, are provided. A Doppler angle between a direction of ultrasound signals and an axis of a flow may be estimated to improve the accuracy of the flow velocity estimation that is based on Doppler effects. A sensor may be mounted on or in an ultrasound probe to obtain a reference orientation of the ultrasound probe and an orientation of the ultrasound probe relative to the reference orientation when the ultrasound probe is moved to other positions. The Doppler angle may be estimated based on the orientation of the ultrasound probe.

  • Patent number: 8416855
    Abstract: A coding mode selection method for selecting a coding mode for motion vector estimation is disclosed. The method includes the following steps. First, a first coding mode is selected to perform motion vector estimation for a macroblock having M sub-blocks. M motion vectors corresponding to the M sub-blocks are separately calculated. It is determined whether correlations for the M motion vectors match to a predetermined condition. If not, the first coding mode is selected and the M motion vectors are utilized to perform a motion vector estimation; and if so, a second coding mode is selected and the N motion vectors corresponding to the second coding mode are utilized to perform the motion vector estimation, wherein the N motion vectors are generated by using the M motion vectors and 1?N<M.

    Abstract: An apparatus for analyzing a physical signal representing a physical phenomenon is provided. The apparatus comprises an analog-to-digital converter, a slope calculator, a local extrema identifier, a residual signal constructor and an intrinsic mode function (IMF) extractor. The analog-to-digital converter is used to convert the physical signal into a plurality of data points. The slope calculator is used to calculate slope of each data point. The local extrema identifier is used to identify a plurality of local extrema of the slopes. The residual signal constructor is used to construct a residual signal of the physical signal from the data points corresponding to the local extrema of slopes. An IMF extractor is used to extract an intrinsic mode function indicative of an intrinsic oscillatory mode in the physical phenomenon by subtracting the residual signal from the physical signal. A method for analyzing a physical signal representing a physical phenomenon is provided.

  • Patent number: 7383585
    Abstract: A method controls the access times of an optical disc end discs of the same. The method includes the following steps. First, an optical disc drive obtains the addresses of a life flag and a medium key block (MKB) by reading a private flag of an optical disc. The life flag and the MKB are used to control the access times of the optical disc. After confirming the addresses of the life flag and the MKB, the optical disc drive obtains an optical power signal to determine the power that should be used to read the MKB. When the optical disc drive uses the appropriate reading power to access the MKB, the recognizable number of access times in the 4KB data is reduced, and the medium key signal is extracted to be confirmed if it is recognizable to restate the main data.
