  • Patent number: 11497764
    Abstract: Disclosed herein are fully synthetic polymer-based lung surfactant materials, for the first time, as next generation SRT. In vitro studies on these polymer lung surfactants show that the candidate materials effectively mimic the surface tension controlling properties of currently marketed natural lung surfactants. Further, the polymer lung surfactants have strong protein resistance, which makes this class of materials promising also for potential use in Acute Respiratory Distress Syndrome (ARDS) treatment.

  • Patent number: 11454770
    Abstract: Provided are an apparatus and method for adjusting an optical axis. In the apparatus, an iris diaphragm and a quadrant photodiode (QPD) are used to align optical axes of an optical system of the apparatus so that optical transmission efficiency between an optical transmitter and an optical receiver can be increased. Since a hole of the iris diaphragm can be adjusted to be small, a beam larger than a light-receiving area of the QPD can be included in the light-receiving area, and optical axis alignment is facilitated accordingly. When the QPD and the iris diaphragm are applied to the apparatus, it is possible to simultaneously perform data transmission, tracking, and optical axis alignment. An optical fiber end surface and optical axes of lenses arranged in parallel are aligned in the apparatus so that alignment between two terminals can be easy and reception efficiency can be increased.
