  • Publication number: 20140005475
    Abstract: An image tracking system and an image tracking method. The image tracking system includes image capture module, detection module and processing module. The image capture module captures real-time image. The detection module analyzes the real-time image, and detects whether positions of a plurality of instruments are disposed in the real-time image. The processing module defines buffer zone in the real-time image, and analyses whether the instruments are disposed in the buffer zone based on the positions of the instruments, and determines whether spacing distance between the instruments is small than preset distance. When the spacing distance is smaller than the preset distance or the instruments are disposed outside the buffer zone, the processing module emits controlling signal to control the image capture module to move to capture position. As a result, the present invention may achieve image tracking real time and provide stable image.

  • Patent number: 7788767
    Abstract: An automatic door shutter includes a stationary plate and a pressing plate pivotally combined together and with a resilient body located therebetween. Additionally, a pivot of the stationary plate has a sliding notch accepting an S-shaped resilient sheet abutting the pressing plate. By attaching the stationary plate and the sliding base to a door frame and a door respectively, the resilient body pushes the pressing plate to shut the door automatically. When the door is pushing to fully open, the pressing plate pivots to the stationary plate, and the S-shaped resilient sheet slides in the sliding recess and is compressed to deform to become U-shape. Until the door is fully open, the resilient sheet which is U-shaped causes an outward pushing force to the pressing plate to keep the door open constantly.

Additionally, a pivot of the stationary plate has a sliding notch accepting an S-shaped resilient sheet abutting the pressing plate. By attaching the stationary plate and sliding base to a door frame and a door board respectively, the resilient body pushes the pressing plate to shut the door board automatically. When the door board is pushing to fully open, the pressing plate pivots to the stationary plate and then the S-shaped resilient sheet slides in the sliding recess and is compressed to deform to become U-shaped one. Until the door board is fully open, the U-shaped resilient sheet causes an outward pushing force to the pressing plate to keep the door board open constantly.
