  • Optical distance detection system
    Patent number: 8743348
    Abstract: There is provided an optical distance detection system which includes a light source and a detection device. The light source is configured to illuminate a surface of an object. The detection device is configured to receive a reflected light from the surface of the object and to output a distance of the object according to the reflected light. The detection device includes a sensing module and a calculation module. The sensing module is configured to receive the reflected light to accordingly generate an image. The calculation module is for outputting the distance according to a light spot position and a light spot size of the reflected light forming on the image.

  • ELECTRONIC DATA PROCESSING DEVICE WITH DUAL-CPU
    Publication number: 20070234007
    Abstract: The present invention discloses an electronic data processing device with dual-CPU, comprising: the first CPU and the second CPU, wherein the first CPU is connected to the second CPU. The first CPU being low power type executes the first process which needs long time to execute. The second CPU with stronger computing ability in calculating than the first CPU executes the second process which requires quick arithmetic. The first CPU may output an interrupt to the second CPU in order to command the second CPU to execute the second process. The second CPU also can output an interrupt to the first CPU, thus to command the first CPU to transfer the data worked by executing the first process.
