Publication number: 20050060926Abstract: 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.Type: ApplicationFiled: November 8, 2004Publication date: March 24, 2005Inventors: Kyeong-Won Lee, Youn-Hwan Kim

Publication number: 20030200084Abstract: 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.Type: ApplicationFiled: April 16, 2003Publication date: October 23, 2003Inventors: Youn-Hwan Kim, Chun-Mo Kang
