  • Patent number: 10538890
    Abstract: A hydraulic ship lift, including: a mechanical synchronizing system; a stabilizing and equalizing hydraulic driving system; and a self-feedback stabilizing system. The stabilizing and equalizing hydraulic driving system includes first resistance equalizing members arranged at corners of branch water pipes or/and second resistance equalizing members arranged at bifurcated pipes, circular forced ventilating mechanisms arranged at front of water delivery valves of a water delivery main pipe, and pressure-stabilizing and vibration-reducing boxes arranged behind the water delivery valves. The self-feedback stabilizing system includes a plurality of guide wheels; each guide wheel of the self-feedback stabilizing system is fixed on a ship reception chamber through a supporting mechanism.

  • Patent number: 10497396
    Abstract: A method, system and computer program product for improving the recording of classroom lectures or other such presentations. A video frame containing a whiteboard image is converted into a black and white image for the detection of boundaries. These boundaries are classified as horizontal or vertical lines. Quadrangles are then formed using spatial arrangements of these lines. The quadrangles that are most likely to spatially coincide with the boundaries of the whiteboard image are identified. The quadrangles are then sorted (ranked) based on specific characteristics, such as size and position. The area corresponding to the identified quadrangle in the video frame is then cropped. Furthermore, the speaker in the video frame can be removed based on detecting changes that are characteristic of movements of a speaker. In this manner, the visual and educational experience involved in the recording of classroom lectures or other such presentation is improved.
