Abstract: Methods and systems are disclosed related to determining whether there is a proper fit between a user interface and a face of a user. The methods and systems involve generating seal information associated with a seal region between a face of a user and a current user interface donned on the face of the user. The methods and systems are further related to analyzing the seal information to determine whether a leak exists in the seal region. If the leak exists, the systems and methods include analyzing the seal information to determine a location of the leak within the seal region. The systems and methods further include determining a new user interface to replace the current user interface based on the current user interface and the location of the leak.

Abstract: A method for determining a degree of degradation of a user interface worn by an individual during one or more uses of a respiratory therapy system includes receiving data associated with the user interface. The method further includes determining, based at least in part on the received data, a value of at least one degradation indicator associated with the user interface. The method further includes determining the degree of degradation of the user interface based at least in part on the value of the at least one degradation indicator.

Abstract: Disclosed is a context-aware real-time spatial intelligence provision system that estimates the locations of persons or things captured in a video by extracting objects representative of the persons and the things from the video captured by viewing a real space and placing the extracted objects in a virtual space to which a digital twin technique is applied. The disclosed context-aware real-time spatial intelligence provision system allows people to keep the distance between each other indoors, thereby preventing the spread of an infectious disease such as COVID-19.

Abstract: Disclosed are an open-porous metal foam and a method for manufacturing the same. An open-porous metal foam according to an exemplary embodiment of the present invention is made of an iron-based alloy including 15 wt % or more of chrome and 5 wt % or more of aluminum. The open-porous metal foam is a semi-product that is formed of iron or the iron-based alloy that does not include chrome and aluminum or includes a smaller amount of chrome and aluminum in the powder when manufacturing, and the surface and the open pore thereof are uniformly coated with the powder of the iron-chrome-aluminum alloy and the organic binding agent. When heat treatment is performed under a reduction atmosphere, sintering is performed.
