Latest Patents
Yong Hun Cho's latest patents include a "Method and apparatus for pulse width modulation in a switching amplifier." This invention provides a method for output pulse width modulation in a digital amplifier, which involves determining the sign of a resulting value by adding or subtracting a predetermined offset from an input audio signal. The process includes a switching step that outputs the audio signal based on the determined sign and an adjusting step that adds a predetermined switching time to the output signals. Finally, the modulating step performs pulse width modulation on the adjusted audio signals, resulting in a first and second modulation signal.
Another significant patent is the "Scroll-type compressor having improved pressure equalizing passage." This invention features a scroll plate with first and second pressure equalizing passages designed to maintain effective functioning during the crescent-shaped pocket's movement. The design ensures that the pressure in the interior space does not overwhelm the back pressure pocket, thus enhancing the compressor's efficiency.
