  • Publication number: 20200129080
    Abstract: A biometric authentication system and method are provided that are based on PPG signals acquired using non-invasive methods, such as pulse oximeter, for example. Compared to the other biometric authentication approaches, PPG signals are relatively easy to acquire, relatively difficult to duplicate, and can be adaptively updated, which are qualities that make them well suited for biometric authentication. However, PPG signals are often corrupted by motion artifacts (MAs) due to the unique measurement technique, i.e., placement of a sensor close to the skin. The system and method employ an MA removal algorithm to remove or mitigate MAs to provide a PPG-based biometric authentication solution that is robust and that can be implemented relatively easily and cost effectively.

  • Patent number: 10539820
    Abstract: A touch-panel liquid-crystal display device in one embodiment includes a metal line formed on a thin-film transistor array substrate, a gap column spacer and a push column spacer on a portion of a color filter array substrate that corresponds to an intersection of gate and data lines of the thin-film transistor array substrate, and a liquid-crystal layer between the thin-film transistor array substrate and the color filter array substrate. The gap column spacer and the push column spacer have the same height and the gap column spacer is located on the metal line, which facilitates an exposure process, minimizes generation of foreign substances when printing an alignment layer, and enables adjustment of the optimum amount of liquid crystals when liquid-crystal dotting is performed. The push column spacer is located on the metal line when the device can be pushed or bent by external force, and thus increases panel rigidity.
