Title: Mobile terminal apparatus having emergency receipt service function and communication system, service method thereof
Inventor: YU SEUNG RYOL
IPC: H04B1/40
Filed: 2006-02-24
Abstract: A communication terminal having an emergency reception function, a communication system having the same, and a service method thereof are provided to enable people within a home to quickly grasp an emergency situation by turning home appliances such as a TV on and controlling volume of the home appliances so as to have a level higher than a pre-set level, when an emergency reception signal is received. A communication terminal having an emergency reception function comprises a baseband processing part(105), a modulation/demodulation part(107), a control part(109), and an IR signal transmitting part(117). The baseband processing part(105) converts a signal inputted through a reception signal processing part(103) into a digital signal. Also the baseband processing part(105) converts a digital signal inputted from the outside into an analog signal and outputs it to a transmission signal processing part(121). The modulation/demodulation part(107) demodulates and outputs a digital signal inputted from the baseband processing part(105), and modulates and outputs a signal to the baseband processing part(105). The control part(109) judges whether a value demodulated by the modulation/demodulation part(107) is a CID value. In case the demodulated value is a CID value, the control part(109) judges whether the CID value is an emergency reception number. If the CID value is an emergency reception number, the control part(109) creates and outputs an electronic device operation control signal according to the emergency situation alarm information received together with the emergency reception number. The IR signal transmitting part(117) converts the electronic device operation control signal into an IR signal and transmits it.

Abstract: 본 발명은 다양한 성상의 남은음식물류 쓰레기로부터 발생하는 고형물과 탈리액을 독립적이며 동시에 자원화하기 위한 처리공정을 구성함에 있어 햄머밀 방식의 자동분쇄선별기와 원심식 고형물회수기의 조합과 화학적 응집반응기의 설비를 연속공정으로 구성하여 유기성 고형물을 필요로 하는 양만큼 임의 조절하여 분리하고 그로부터 남는 고농도의 액상탈리액을 각 단계별마다 독립된 저장조에 의해 부상스컴의 회수 및 여액의 효소반응을 거치도록 하여 혐기성 소화에 의해 안정적으로 바이오가스를 생산하도록 하는 자원화 설비의 구성과 운전방식에 관한 것이다. 
     이때, 발생되는 탈수고형물은 퇴비화, 건사료화 또는 탄화 등의 자원화가 가능하고 액상탈리액은 바이오가스를 생산하는 동시에 혐기성소화 처리된 배출수는 활성오니법과 연계하여 방류기준에 적합한 수질을 확보하도록 함으로서 종합적이며 효과적인 음식물류쓰레기를 자원화하는 공정구성에 관한 것이다. 
     본 발명은 음식물류쓰레기를 자원화하기 위해 고액분리 시 발생되는 탈리액은 고농도의 유기물 또는 무기물이 함유되어 있어 이를 처리해야 하는 경우 고농도의 배출수가 다량으로 발생되어 약품비용이 과다하게 소요되므로 운영비에 부담을 갖는 상황이며 약품처리에 앞서 호기성 미생물에 의한 효소가수분해 전처리공정을 거치게 하여 약품소요량을 줄이고 고형물 분리 및 탈수에 필요한 기계구성을 간단히 하는 등 문제점을 해결하기 위한 공정의 구성이다. 
     특히, 성상이 다른 어떠한 음식물류 쓰레기일지라도 음식물류를 이물질로 부 터 자동으로 분리하고 고형물의 입자를 죽 상태로 분쇄한 후 고액분리기에 의해 분리된 고형물은 이미 알려진 퇴비화, 사료화 및 탄화 등 적정의 처리공정에 의해 필요에 따른 최종산물로 전환시키고, 동시에 쓰레기의 80％ 이상을 차지하는 고농도의 액상물질을 에너지 자원인 바이오가스로 전환시키는데 있어 최종 자원화목적에 따라 고형물과 탈리액의 회수비율을 자유로이 조절할 수 있도록 하는 공정 운영상의 특징을 갖는다. 
     이를 위해 원심분리식 고액분리장비를 햄머방식의 자동분쇄선별기와 직렬로 구성하고 발생된 탈리액을 응집반응에 앞서 다단식 저장조을 이용하여 부유성 스컴을 회수하고 저장조마다 호기성 미생물효소에 의해 가수분해하여 응집효율을 저해하는 물질을 저감함으로서 고액분리에 소요되는 약품투입량을 최소화하여 약품비용을 절감하고 탈수고형물 처리효율과 바이오가스의 회수량을 극대화하는 것을 특징으로 한다. 
     특히, 본 발명은 고형물을 분리할 때 액상물질 중에 포함되어 있는 다양한 이물질과 혐기성 소화에 의한 처리가 극히 어려운 비분해성 또는 난분해성인 조대 고형물들이 효과적으로 제거되도록 함으로서 혐기성소화에 의한 바이오가스 생산시 비정상적 공정운영상의 문제를 유발시킨 주요 원인을 해결한 공정으로 지금까지 고형물의 자원화에 집중된 남은음식물류쓰레기의 자원화시설 구성 시 고형물 회수물의 처리와 동시에 고농도의 유기물을 함유한 탈리액을 바이오가스로 전환시키는 혐기성 처리공정이 안정적이고 고효율로 진행되도록 전처리장치를 구성한 것을 주요 공정구성으로 한다. 
     본 발명은 음식물류 쓰레기 자원화공정의 하나인 바이오가스 에너지화 위한 처리공정뿐만 아니라 액비화공정 또는 하수병합처리 시 산발효를 위한 전처리 그리고 퇴비 및 탄화공정 그리고 그 밖의 자원화를 위한 모든 공정에 적용될 수 있도록 하며, 지금까지 많은 공간을 차지하고 인력에 의존하여 불연속적으로 운영되어온 기존의 전처리 공정을 간소화 하였으며 탈리액 처리에 과다하게 소요된 약품비용이나 연료 및 전력비용을 절감하도록 하였다.

Abstract: An electroluminescent display device and a driving method thereof are provided to detect contacted position in a touch screen by extracting varied current through output current. An electroluminescent display device includes LEDs, capacitors(Cst), driving thin film transistors(DT), switching units(ST), voltage amplifiers(202), and variable resistors(Rc). The LEDs(Light Emitting Diode) are illuminated by output current. The capacitors store data signals received from data lines.

The switching units, which are connected between the capacitor and data lines, deliver the data signals using scan signals received from scan lines. The voltage amplifiers amplify voltages as much as initial output current by detecting the output current varied by external pressure signals. The variable resistors, which are connected between the LEDs and driving thin film transistors, vary the initial output current in response to amplified signals from the voltage amplifiers.
