Abstract: Systems, apparatus, and methods for detecting air breathed by a user and/or one or more gases are provided herein. In some embodiments, an apparatus may include a test material adapted to reduce in size when exposed to one or more stimuli. In some embodiments, one or more chemicals may be disposed on the test material and, when exposed to the air breathed by the user, the one or more chemicals are adapted to transform from a first color to a second color. In some embodiments, when the test material reduces in size an intensity of the second color increases. The apparatus may further include a face mask. In this regard, the test material may be removably attached to the face mask. The apparatus may further include a spectrophotometer configured to determine if the one or more chemicals have transformed from the first color to the second color.

Abstract: A fault detection method for a rotating machine based on sparse time synchronous averaging is disclosed, and the method includes: collecting a vibration signal and a rotating frequency or rotating frequency pulse signal of the rotating machine and performing analog-to-digital conversion to obtain the vibration signal and rotating speed information by a sensor; according to the type and number of detection components in the rotating machine, constructing a component-aware comb vector g based on the vibration signal and rotating speed information, wherein the type includes the gear, rotor and bearing; constructing a quasi-time synchronous average vector w based on the component-aware comb vector g; constructing a sparse time synchronous averaging model F by using the quasi-time synchronous average vector w; solving the sparse time synchronous averaging model F with an optimization solution algorithm to obtain a sparse spectrum and a reconstruction time signal.

Abstract: A chemical reaction hazard analysis method is disclosed. Safety data and preventive measures of a chemical reaction are obtained through analysis of material stability, reaction process hazards and reaction runaway. The method can shorten a distance from laboratory to industrialization and realize an organic combination and application of technology, safety and engineer. The data obtain by the method can provide underlying basic data for process design, engineer amplification and the like, and lay a foundation for realizing process safety, improving quality and increasing efficiency.

Abstract: A cryoablation temperature control method, system and computer-readable storage medium.

Abstract: The invention discloses a video rendering method and a video rendering device, said method comprising registering a trigger operation of a video node after parsing it on a webpage, creating a video component corresponding to said target video node and using said video component to render said target video node only upon detection of said trigger operation oriented towards said target video node. The video rendering method disclosed by this invention can create the corresponding video component according to a user's playing demands and prevent the system resource waste arising from the system's automatic allocation of a video component to the video node on the webpage and the lack of system memory and poor user experience incurred thereby.

Abstract: Provided are a photomask and a method of manufacturing a color filter substrate. This belongs to the field of display technologies, and can be used to simplify manufacturing process of the color filter substrate and improve manufacturing efficiency of the color filter substrate.

Abstract: A webpage update method and apparatus includes setting a dynamic area according to a visible area of a browser, then using an area, corresponding to the dynamic area, in a target webpage as an area to be rendered, storing webpage update content generated in the area to be rendered in a first preset storage area, so as to read, at one time, the webpage update content in the first preset storage area, to complete rendering of the area to be rendered, thereby ensuring that the content currently displayed in the visible area is updated content. Meanwhile, webpage update content generated in an area other than the area to be rendered is stored in a second preset storage area, and rendering of the corresponding area is temporarily not performed, so that a working amount of a rendering operation can be reduced.
