  • Patent number: 12210977
    Abstract: Disclosed are an ultra-high sensitivity target signal detection method based on analysis of a noise signal of a sensor using deep learning based anomaly detection and a system using the same. More particularly, disclosed are a method and apparatus for receiving a noise signal from a sensor and inputting data to an artificial neural network trained with a normal noise signal to determine whether or not a target signal is present. The target signal detection method is capable of detecting a target signal having a very low concentration that can be detected by a conventional sensor, whereby the target signal detection method is useful in developing an ultra-high sensitivity sensor.

  • Publication number: 20250000142
    Abstract: Provided herein is an aerosol-generating article with enhanced vapor production. The aerosol-generating article according to some embodiments of the present disclosure includes a medium portion, a support structure which is disposed downstream of the medium portion and includes a first tubular structure having a first hollow formed therein, a cooling structure which is disposed downstream of the support structure and includes a second tubular structure having a second hollow formed therein, and a mouthpiece portion which is disposed downstream of the cooling structure. Here, an upstream end of the second tubular structure may abut a downstream end of the first tubular structure, and an average cross-sectional area of the second hollow may be larger than an average cross-sectional area of the first hollow. The cross-sectional area difference enhances an air flow diffusion effect, thereby eventually improving vapor production of the aerosol-generating article.

  • Publication number: 20210095385
    Abstract: A method of fabricating a working electrode adapted for reduction of carbon dioxide comprises layering a gold film (Au) over a shrinkable polymer to create a layered structure, heating the layered structure to cause shrinking, for instance, at a temperature of about 130° C., and removing the shrinkable polymer layer. The heating creates a contracted, wrinkled Au film surface owing to a difference in thermal coefficient between the Au film and the underlaying polymer prior to removal of the polymer, and the wrinkled film contains c-shaped wrinkles containing confined spaces in which a local elevated pH level is attained.
