Latest Patents

One of Hyeong-keon An's latest patents is a digital storage system that adopts semiconductor memory devices. This innovative system eliminates the need for moving mechanical components, enhancing reliability and extending the useful life of digital data storage. It minimizes costs, complexity, and size compared to traditional systems like CD players and DAT devices. The system includes a ROM, a system control microcomputer, a digital signal processor (DSP), and a D/A converter. In playback mode, the DSP reads and decodes digital audio data stored in the ROM, while the D/A converter transforms this data into an analog output signal. In record/playback mode, an A/D converter and EEPROM facilitate the recording of digital data.

Another notable patent is for a noise canceler that applies a pilot-canceling signal to eliminate noise. This system uses a subtracter and MOS transistors to cancel out noise signals present in the composite input. The noise canceler can digitally convert external noise and store inverted noise patterns in memory. When noise is detected, the system outputs inverted data to cancel out unwanted sounds from various sources, including electrical appliances and vehicles.
