Latest Patents
One of Sangmoon Lee's latest patents is a "Signal processing apparatus and method for removing reflected wave generated by robot platform." This invention includes a transfer function measuring unit that measures an inter-channel transfer function (IcTF) from signals of multiple channels. It also features an impulse response obtaining unit that derives an inter-channel impulse response (IcIR) from the measured IcTF. The reflected wave removing unit differentiates between a direct wave generated by a sound source and the reflected wave with a time delay, effectively removing unwanted echoes.
Another significant patent is the "Artificial ear and method for detecting the direction of a sound source using the same." This invention comprises a plurality of microphones and structures positioned between them. The design allows for different amplitudes of output signals based on the direction of the sound source. The method for detecting sound direction involves analyzing these signals to determine the front-back discrimination and the angle corresponding to the sound source's position.
