  • Publication number: 20220169203
    Abstract: A vehicle monitoring system adapted to manage and monitor vehicles includes a management platform and a control device connected thereto and installed in each vehicle. The control device includes a processor where predetermined conditions set as standards of safe driving are stored, a camera lens set adapted to capture actual images, a storage unit adapted to store the captured images, and a reminding unit connected to the processor. The processor compares the captured images with the predetermined conditions, and a comparison result of each vehicle is sent to the management platform for recording and monitoring. If the captured images do not fulfill the predetermined conditions, an abnormal state is shown, and the reminding unit reminds the vehicle driver to reduce the incidence of traffic accidents. The management platform monitors the driving state of vehicles proactively according to the comparison result to enhance occupational safety and emergency response capability.

  • Publication number: 20150310812
    Abstract: A source driver includes an output unit and a pre-charge unit. The output unit includes a first output amplifier to output a first output voltage and a second output amplifier to output a second output voltage. A polarity of the second output voltage is opposite to a polarity of the first output voltage. The pre-charge unit pre-charges an input of the first output amplifier and an input of the second output amplifier during a first period, upon a polarity change of the output unit.

  • Patent number: 8090019
    Abstract: An intra prediction circuit device applied to the H.264 video coding standard is provided. The intra prediction device uses a method of decreasing the repeated operations of the shared terms of the video pixel data to reduce the circuit computation and simplify the hardware architecture. In the intra prediction scheme, the computational complexity can be lessened by implementing not only the adder based method but also decomposition technique to simplify the algorithm of the intra prediction.

  • Publication number: 20080219350
    Abstract: Different algorithms are used in H.264/AVC intra coding to form three coding levels. Algorithms used in two of the three coding levels reduce calculation complexities and power consumptions. The basic level is an exception, which fully keeps an original picture quality. Thus, various needs can be met by coding in the various levels with the various algorithms.
