  • Patent number: 10572735
    Abstract: A solution is provided for detecting in real time video highlights in a sports video at a mobile computing device. A highlight detection module of the mobile computing device extracts visual features from each video frame of the sports video using a trained feature model and detects a highlight in the video frame based on the extracted visual features of the video frame using a trained detection model. The feature model and detection model are trained with a convolutional neural network on a large corpus of videos to generate category level and pair-wise frame feature vectors. Based on the detection, the highlight detection module generates a highlight score for each video frame of the sports video and presents the highlight scores to users of the computing device. The feature model and detection model are dynamically updated based on the real time highlight detection data collected by the mobile computing device.

  • Patent number: 9965297
    Abstract: Controlling assistance information comprises determining a user mode based on computer input signals generated by a user. If the user is in a passive mode and assistance information is detected, the assistance information is disabled in response to detecting a hidden signal. The assistance information is then enabled if later a reset signal is detected. If the user is in passive mode and assistance information is not detected, the assistance information is enabled in response to detecting a trigger signal. If the user is in an active mode and assistance information is detected, the assistance information is disabled.

  • Patent number: 9568791
    Abstract: Disclosed are a liquid crystal display device and a testing method thereof. The liquid crystal display device includes a plurality of scan lines, and a plurality of data line sets crossing the scan lines, where each data line set includes a first data line, a second data line, and a third data line. The device also includes a shorting bar for the data lines, a first data switch control line and a second data switch control line. Through holes are not used to connect the data lines and the shorting bar, thus disadvantages of display devices caused by defects in through holes is eliminated. Additionally, the area for testing structures is decreased, so that a small-sized liquid crystal display devices can be produced.

  • Publication number: 20120322043
    Abstract: An adaptively-spaced repetition learning system and method facilitate the learning of material over time through the presentation of the material at ever-increasing intervals. Embodiments of the system and method present a stimulus-response pair to a student to obtain a binary response that is either correct or incorrect. The token is next presented to the student based on the student's response. If the response is correct, then the token is presented to the student based on the initial repetition interval without modification. If the response is incorrect, then the learnedness value is reset and the progression through the repetition intervals is restarted. In some embodiments, the initial repetition intervals are dynamically adjusted based on the student's response to obtain revised repetition intervals. This is achieved by manipulating the exponent of the mathematical term representing the curve of the repetition intervals.
