  • Patent number: 12130220
    Abstract: A biosensor using an exceptional point is disclosed. A biosensor according to one embodiment of the present disclosure includes: a biosensing unit configured to output wavelength-separated optical signals from destruction of an exceptional point resulting from attachment of biomolecules; a detection unit configured to convert the wavelength-separated optical signals into wavelength-separated electrical signals; an analysis unit configured to measure a beat frequency resulting from the wavelength-separated electrical signals; and a determination unit configured to determine a wavelength difference resulting from the beat frequency, thereby determining the amount of the biomolecules therefrom.
    Type: Grant
    Filed: March 19, 2020
    Date of Patent: October 29, 2024

  • Publication number: 20220293930
    Abstract: The present disclosure relates to a positive electrode for a lithium secondary battery, including a first positive electrode active material layer including a nickel-rich first positive electrode active material and a second positive electrode active material layer including a solid electrolyte and a second positive electrode active material. The positive electrode for a lithium secondary battery shows improved life characteristics and heat stability by virtue of the introduction of the second positive electrode active material layer.

  • Patent number: 10152895
    Abstract: Disclosed is an automatic climbing and gliding method of a high altitude unmanned aerial vehicle (UAV). The disclosed method includes setting a cylindrical virtual flight region so that the high altitude UAV climbs and glides, setting a first target point on an end of a first flight radius which is vertically arranged to form the virtual flight region, setting second to Nth target points at arbitrary second to Nth flight radii sequentially arranged above or below the first flight radius, having the target points have a predetermined plane slope angle, and allowing the UAV to climb along a straight path line sequentially connecting each of the target points.

  • Publication number: 20160216602
    Abstract: A mask including: a transparent substrate and a light blocking layer thereon. The transparent substrate includes a first transmitting portion and a second transmitting portion each configured to pass light, and a light blocking portion configured to block light. The first transmitting portion includes a first transmitting region configured to pass light and a first light blocking region configured to block light, and area centers of the first transmitting region and the first light blocking region substantially coincide. The second transmitting portion includes a second transmitting region configured to pass light and a second light blocking region configured to block light, and area centers of the second transmitting region and the second light blocking region substantially coincide, so that the first transmitting portion is configured to pass light of a greater intensity and the second transmitting portion is configured to pass light of a lesser intensity.
