  • Publication number: 20250017489
    Abstract: A method for counting coughs is provided. The method includes determining a plurality of time points in the sound signal, extracting a plurality of cropped signals from the sound signal by cropping portions of the sound signal, wherein each of the cropped portions corresponds to a signal with a predetermined time length from each of the determined time points in the sound signal, transforming each of the plurality of cropped signals into a spectrogram image, thereby forming a plurality of spectrogram images, determining whether each of the plurality of spectrogram images represents a cough by inputting each of the plurality of spectrogram images into a cough determination model, wherein the cough determination model is a classification model trained to classify the inputted spectrogram image into a cough or non-cough, determining a plurality of tags according to results determined by the cough determination model.

  • Patent number: 11867936
    Abstract: A laminate film comprising a retardation layer exhibiting blocking characteristics against specific ultraviolet rays even in a state where the retardation layer does not include any ultraviolet absorber or light stabilizer. The laminate film which can be used alone or in combination with an appropriate sunscreen or a light stabilizer as needed to selectively block ultraviolet rays in a region requiring blocking, without affecting display performance, such as color senses and image quality, of a display device. The laminate film can also be formed with a lower thickness without requiring a separate ultraviolet blocking layer, and also has excellent durability, because the laminate film exhibits a certain ultraviolet blocking property even in the absence of an ultraviolet absorber or light stabilizer.

  • Patent number: 11614660
    Abstract: A transmittance-variable film and a use thereof, where the transmittance-variable film can control pretilt of a liquid crystal interface by applying a liquid crystal alignment film containing splay oriented liquid crystal molecules, and can vertically and horizontally orient a liquid crystal layer or a liquid crystal interface according to an average tilt angle of the liquid crystal alignment film to ensure uniformity of driving and fast response speed. In addition, by applying a liquid crystal alignment film, the transmittance-variable film can be implemented in various modes with a simple coating-drying-curing method excluding the rubbing process by controlling an arrangement of liquid crystal molecules in a liquid crystal alignment film other than the pretilt control method using the conventional rubbing method.
