  • Patent number: 9739414
    Abstract: A multi-axis carrying device includes a base, first and second main moving units mounted to the base, a first platform connected to the first and second main moving units, and first and second driving units. The first driving unit has a first output structure coupled to the first main moving unit. The second driving unit has a second output structure coupled to the second main moving unit. When the first and second output structures move in a moving direction, the first and second main moving units are driven to move two opposite sides of the first platform in another direction perpendicular to the moving direction.

  • Patent number: 8401286
    Abstract: An image detecting device receives a video signal stream including at least one frame. Each frame includes rows of data, and each row of data has a plurality of pixels. The frame has an image portion and a blank portion. The image detecting device includes a characterizing unit and a searcher. The characterizing unit receives the pixels and determines pixel characterization values thereof. The searcher includes an image comparator and a blank comparator. The image comparator and the blank comparator evaluate the pixel characterization value of a current pixel to determine whether the current pixel belongs to the image portion or the blank portion. The searcher derives a position of the image portion based on determined results of the image comparator and the blank comparator. An image detecting method is also disclosed.
