  • Patent number: 8204955
    Abstract: A method and system are provided for remotely analyzing multimedia content, in particular video, and extracting information from such multimedia content. The system analyses, e.g. a video file by way of an FTP, file upload or streaming data etc., and configuration settings specified in one embodiment by a separate entity at one of multiple server entities. The system also comprises one or more remote server entities utilizing data storage and data processing capabilities. In one embodiment the client sends a video source and configuration settings over a network, the remote server accepts the video source, generates configuration settings, and a data processing module analyzes the video content to extract data from the video.

  • Publication number: 20110254703
    Abstract: Techniques are generally described related to a pedestrian safety system. One example pedestrian safety system may include a sound collector configured to collect an audio signal in an environment of a pedestrian; a processor configured to analyze the collected audio signal to determine whether the audio signal is associated with a vehicle and a distance between the vehicle and the pedestrian; and a notification device configured to notify the pedestrian when the processor determines that the audio signal is associated with the vehicle and the distance is less than a predetermined distance.

  • Publication number: 20100041563
    Abstract: The invention provides a method for identification of alleles. In this method, genomic DNA is used as target. Multiple allele-specific PCR amplification are carried out with a group of primers comprising one or more allele-specific primers for a target gene, a universal primer, and a common primer; and a DNA polymerase without 5? to 3? exonuclease activity. The PCR products are hybridized with tag probes immobilized on a DNA chip. Results are determined based on the signal intensity and the position of the probe immobilized on the array. Each allele-specific primer comprises a unique tag sequence at the 5? end. Each tag probe immobilized on the DNA chip comprises a sequence identical to its corresponding tag sequence; and each tag probe hybridizes only with the complementary sequence in the PCR amplification product.
