Title: Method for eliminating a modulation noise in digital audio device
Inventor: ON SUN GI
IPC: H04H40/36
Filed: 2001-09-24
Abstract: PURPOSE: A method for eliminating a noise when modulating a signal in a digital audio device is provided to eliminate a harmonic noise generated by a switching frequency for converting an audio signal of an AM(Amplitude Modulation) radio broadcasting channel into PWM(Pulse Width Modulation) audio data. CONSTITUTION: A control unit sets a current operation mode as a radio receiving mode according to the key input of a user(S10). The control unit confirms whether a frequency tuning band of a radio broadcasting channel set by the user corresponds to a band of an AM radio broadcasting channel(S12). If the frequency tuning band of the radio broadcasting channel corresponds to the band of the AM radio broadcasting channel, the control unit controls the operation of a frequency converting unit and down-converts a switching frequency provided to a digital audio signal processing unit from 384KHz to 196KHz(S13). If the frequency tuning band of the radio broadcasting channel corresponds to an RF(Radio Frequency) band corresponding to an FM(Frequency Modulation) radio broadcasting channel, the control unit maintains the switching frequency as predetermined 384KHz(S14). The digital audio signal processing unit modulates PCM(Pulse Code Modulation) audio data converted in a PCM modulating unit into PWM audio data using the switching frequency(S15), and processes the modulated PWM audio data(S16). Audio data with an audible band filtered through an LPF(Low Pass Filter) are amplified and outputted as a sound through an amplifying unit and a speaker(S17).

Title: 미끄럼방지용 급제동 장치
Inventor: KIM BONG HYUN
Filed: 2001-10-23
Abstract: 자동차의 제동에 관한 것으로 주행중인 자동차가 급제동 등으로 일정한 제동거리를 확보하지 못한 경우, 사고로 이어질 수 밖에 없는데, 이 안전거리는 다분히 운전자가 노면의 상태, 타이어의 상태,본인의 신체적 여건을 고려해서 운행해야 함에도 현실은 많은 차량과 경주하듯이 밀려 다녀야 하기 때문에, 순간 어떤 사항이 닥칠지 모르며 감속의 정도와 제동의 작용이 운전자의 호흡과도 같이 무 의식적으로 한치의 오차없이 일어나야 한다. 
     그러나 예기치도 못한 우중의 운전이나 산길을 돌아 결빙 상태의 길을 만나기도 하고, 병행 차선의 돌발적 상황으로 감속과 제동을 하여야 하는데도 운전자가 평소 느끼던 속도감이 아닌 미끄럼이 일어날 경우, 운전자가 당황하게 되고 속수무책으로 사고와 연결되는 것을 보게 된다. 
     이러한 불가항력적인 상황에서 단 1m만 제동 거리를 단축할 수 있어도 그 기여는 만족 할 수 있을 것이다. 
     제동의 원리는 타이어의 구름을 정지시켜 노면과의 마찰력을 최대로 얻는데 있다. 
     즉, 제동이 우수한 타이어의 개발이나 기계적 순간 연속 제동으로 마찰면의 변화를 주어 제동 거리를 단축시키는 방법등 본 고안과는 다른 것으로 이러한 장치들을 통한 감속을 받고도 운전자로서는 속수 무책인 경우에 결정적인 정지을 확인하기 위한 운전자로서의 마지막 수단을 제공한다. 
     다시 말하면, 급제동시에는 자체의 중량과 달려온 속도등에 의한 제동 거리는 타이어 제동만으로는 그 한계를 벗어날 수 없고, 특히 빗길,눈길 ,비탈길등의 미끄럼이 일어나 마찰 계수가 현저히 떨어진 경우는 타이어에 의한 제동에는 속수 무책일 수 있다. 
     본 발명은 현재 차량의 브레이크 시스템을 아무리 보강 하여도 넘을 수 없는 제동한계 거리을 차량에 별도로 장착한 급제동 장치로 마지막 1m의 단축을 목표로 사고를 방지 하자는 것이다. 
     본 장치는 일회 혹은 2∼3 회 사용할 수 있는 보조 브레이크 장치이다.
