  • Publication number: 20200295664
    Abstract: A method for controlling a DC-DC conversion system having power conversion modules, input sensors, an output sensor and a controller, in which each of the power conversion modules has one or more conversion units. The output sensor detects an output signal of the DC-DC conversion system. The input sensors detect input voltage signals located at series-connected first sides of one or more conversion units respectively. The controller receives the output signal and the input voltage signals. The controller generates a first control signal according to the output signal and an output reference signal. The controller generates second control signals according to the input voltage signals and input reference voltage signals. The controller outputs a modulation signal corresponding to a corresponding one of the second control signals according to the first control signal and the corresponding second control signal, to control switches of a corresponding conversion unit.

  • Patent number: 10761867
    Abstract: Various embodiments include nested emulation for a source application and source emulator. Duplicate source ISA libraries redirect the source emulator library calls to a target library, thereby forcing the native emulator through proper emulation channels between first and second ISAs. Other embodiments concern accelerating dynamic linking by determining certain function calls that, rather than being processed through emulation of PLT code, are instead directly called without the need for PLT code translation. Some embodiments address both nested emulation and accelerated dynamic linking but other embodiments include one of nested emulation and accelerated dynamic linking. Other embodiments are described herein.

  • Patent number: 10735710
    Abstract: A stereo vision image calibration method is applied to an image capturing device having a first camera, a second camera and an image rectifying function. The first camera and the second camera are arranged along a first direction. The first camera and the second camera are respectively utilized to acquire a first image and a second image. The image rectifying function rectifies the first image and the second image by a stereo vision parameter. The stereo image calibration method includes selecting the rectified first image and the rectified second image to compute a global disparity vector between the adjust image and the reference image, and if a vector component of the global disparity vector along a second direction which is different from the first direction has non-zero value, processing a stereo vision calibration according to the vector component.
