  • Publication number: 20100054541
    Abstract: A driving support system with plural dimension processing units (DPUs) for indicating a condition of a surrounding area is disclosed. The driving support system of a vehicle includes plural image capturing devices disposed around the vehicle; at least a dimension processing unit (DPU) connected with the plural image capturing devices for receiving images from the plural image capturing devices and then producing plural related depth maps; a controller connected with the DPU for receiving the plural related depth maps and then producing an indicating data; and a display device connected with the controller for displaying the indicating data around the vehicle in a vertical view.

  • Publication number: 20100017439
    Abstract: A multimedia data streaming system and a method thereof are disclosed. The multimedia data streaming system is used for transmitting multimedia data to a receiver by means of a streaming server through a dynamic streaming process. The multimedia data streaming system includes a converting module and a scheduler module. The scheduler module is used to obtain the bandwidth condition between the streaming server and the receiver dynamically, it can then request the converting module to convert the original data into streaming chunks with the optimal bit rates in accordance with the bandwidth condition detected; the streaming chunks can then be transmitted to the receiver by means of the streaming server.

  • Patent number: 7129989
    Abstract: This invention presented a universal de-interlacing method and system by the motion detection, the motion adaptive interpolation, the directional edge interpolation, the 3:2 pull-downed detection and the 3:2 Pull-Downed recovery. Four-field motion detection can detect the motion area and the still area. By cooperating with the motion adaptive interpolation and the directional edge interpolation the picture possesses the very clear quality, high contrast, and high resolution. The 3:2 pull-downed detection and the 3:2 Pull-Downed recovery can detect the 3:2 Pull-Downed movie sequence and recover the interlaced fields into a progressive frames universally without too much overhead of computational power.

  • Publication number: 20050194198
    Abstract: A theft-proof device, in which a main machine and a receiver are provided on a car to cooperate with an emitter carried on an owner of the car, so that the main machine of the car activates a theft-proof mechanism when the emitter on the owner exceeds the distance for receiving signals and activates an alarm for asking rescue when the car is driven after being stolen or robbed with the ignition lock being turned on, and the ignition lock then is turned off to prevent the car from initiating, the theft-proof devices can thus develop the function of robbery-proofing and asking rescue.
