  • Publication number: 20050060926
    Abstract: Disclosed is a mosquito attracting and killing apparatus with an air cleaning function. The mosquito attracting and killing apparatus attracts mosquitoes using a UV lamp and the mosquitoes are sucked into a collecting net by operation of a fan. The contiuous operation of the fan prevents the mosquitoes from escaping out of the collecting net and kills them. In addition, the mosquito attracting and killing apparatus employs a hopper having a tapered shape to easily clean the inside of the apparatus and efficiently reflect UV light emitted from the UV lamp.

  • Publication number: 20040181997
    Abstract: Disclosed is a mosquito repelling apparatus with an air filtering function. The mosquito repelling apparatus includes: a collecting container having an inlet, an outlet and a vacant space therein; an ultraviolet ray pylorus lamp installed at the inlet of the collecting container, for trepanning a mosquito; a collecting net installed at the outlet of collecting container; a fan installed within the collecting container such that the mosquito trepanned and killed by the ultraviolet ray pylorus lamp, is sucked into the collecting net during operation thereof; and an optical catalyst-coated layer coated on at least one surface of the collecting container. The mosquito can be killed only with the operation of the fan. The apparatus kills viruses having the mosquito as the mediator and drifting in the air, so that infection of person and domestic animal due to the viruses can be prevented.

  • Publication number: 20030200084
    Abstract: Disclosed is a noise reduction system comprising: a speech separator for receiving environmental noise to generate virtual noise, and subtracting the virtual noise from an externally input sound source to generate virtual speech; a digital filter for using a weight coefficient to filter the virtual noise and generate filtered speech; a subtracter for subtracting the filtered speech generated by the digital filter from the virtual speech to calculate an error; and a weight coefficient generator for using the error and the virtual speech to update the weight coefficient so as to reduce the error. Here, the weight coefficient generator updates weight coefficients in real-time using the steepest descent method so as to minimize a mean square value of the error.
