  • Publication number: 20240115158
    Abstract: A method for counting coughs is provided. The method includes acquiring a plurality of onset signals from the sound signal, wherein the onset signal has a predetermined time length; acquiring a plurality of spectrograms corresponding to each of the plurality of onset signals; determining whether each of the acquired plurality of spectrograms represents a cough using a cough determination model; and calculating a number of coughs included in the sound signal based on a time point of a cough signal. The cough signal is an onset signal corresponding to one spectrogram determined to represent the cough. When a time interval between a first time point of a first cough signal and a second time point of a second cough is within a reference time interval, the first cough signal and the second cough signal are regarded as one cough signal at the first time point.

  • 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.

  • Publication number: 20200009275
    Abstract: The present invention relates to a pigment-coupled mannosyl serum albumin complex and a lymph node-probing composition comprising the same. More particularly, when administered to mice, a pigment-coupled mannosyl serum albumin complex can be observed with the naked eye to exist in a condense state for a long period of time in the inguinal lymph node. Thus, the complex and a composition comprising the same can be useful for probing lymph nodes.

  • Patent number: 10495797
    Abstract: The present application relates to a liquid crystal composition, a polarizing element and a use of the polarizing element. Since the polarizing element may be prepared by a simple coating process, the guest host type liquid crystal composition of the present application allows not only for reducing the manufacturing cost and lightweight thinning of the polarizing element, but also for manufacturing the polarizing element showing an excellent heat resistant stability without changes of absorption spectrum to transmission spectrum even in a severe condition such as high temperature environment. Such a polarizing element can be applied to various display devices such as liquid crystal display devices, EL display devices, field emission display devices, display devices using electronic papers, projection display devices or piezoelectric ceramic display devices.
