  • Publication number: 20170295471
    Abstract: An access point in a geographic routing system and a controlling method thereof are provided. The controlling method of the access point in the geographic routing includes the following steps. A traffic event packet is received by the access point. A back-off timer of the access point is set to be a first back-off time value. The first back-off time value is less than a second back-off time value of any on board unit (OBU) which receives the traffic event packet. The traffic event packet is broadcasted by the access point when the back-off timer is counted down to be zero.

  • Publication number: 20160310852
    Abstract: A game recording apparatus includes a video processing module, a video buffering module, an information converting module, a subtitle buffering module, and a video integrating module. The video processing module is coupled between a game console and video buffering module. The information converting module is coupled between a game controller and subtitle buffering module. The video processing module receives a video signal from game console and codes it, and coded video signal is stored in video buffering module. The information converting module receives an operation information from game controller and converts operation information into a subtitle information and saves it into subtitle buffering module. The video integrating module integrates coded video signal and subtitle information into a game video information with a specific video format. Therefore, requirements of time constraint and computing power can be reduced and operation load and cost of game recording apparatus can be lowered.

  • Patent number: 9400435
    Abstract: A method of correcting an overlay error includes the following steps. First, an overlay mark disposed on a substrate is captured so as to generate overlay mark information. The overlay mark includes at least a pair of first mark patterns and at least a second mark pattern above the first mark patterns. Then, the overlay mark information is calculated to generate an offset value between two first mark patterns and to generate a shift value between the second mark pattern and one of the first mark patterns. Finally, the offset value is used to compensate the shift value so as to generate an amended shift value.
