  • Patent number: 11795285
    Abstract: Embodiments in accordance with the present invention encompass compositions encompassing a latent organo-ruthenium compound, a photosensitizer, one or more monomers which undergo ring open metathesis polymerization (ROMP) and at least two distinct types of UV blockers, where when said composition is exposed to suitable actinic radiation forms a substantially transparent film or a three dimensional object. Surprisingly, the compositions are very stable at ambient conditions to temperatures up to 80° C. for several weeks and undergo mass polymerization only when subjected to actinic radiation under inert atmosphere such as for example a blanket of nitrogen. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as 3D printing materials, coatings, encapsulants, fillers, leveling agents, among others.

  • Patent number: 11682213
    Abstract: The present disclosure provides a method and a device for training a neural network model for use in analyzing captured images, and an intelligent image capturing apparatus employing the same. The neural network model can be trained by performing the image reconstruction and the image classification using based on image data received from a plurality of image capturing devices installed in the monitoring area, calculating at least one loss function based on data processed by the neural network model or the neural network model training device, and determining parameters minimizing the loss function. In addition, the neural network model can be updated through the re-training taking into account the newly acquired image data. Accordingly, the image analysis neural network model can operate with high precision and accuracy.

  • Patent number: 11384949
    Abstract: Disclosed herein are an air conditioner system and a controlling method thereof. In a situation that air-conditioning systems such as air conditioners and refrigerators are installed and operated in a site, real-time operation data are acquired and the air conditioning and efficiency are calculated at the site. By comparing performance data provided by a device manufacturer and the real-time operation data, device performance is corrected for the site's installation environment. By using corrected device performance, it is possible to save building facility energy by providing optimal operation number control suitable for the installation environment.
