Abstract:
The present invention relates to a method for estimating the number of persons in a room based on carbon dioxide concentration using a dynamic neural network. The method comprises: a measurement step for measuring the concentration of carbon dioxide contained in the indoor air; a storage step for storing the concentration of carbon dioxide measured in the measurement step in real time; a neural network configuration step for configuring at least one dynamic neural network part in order to estimate the number of residual persons positioned in a room using the concentration of carbon dioxide stored in the storage step; a neural network learning step for comparing the number of residual persons estimated from the dynamic neural network part configured in the neural network configuration step with a reference value previously input for the number of residual persons, comparing an error between the number of residual persons and the reference value with a predetermined threshold, and adjusting a weighted value and a deflection value of a transfer function which configures the dynamic neural network part in a direction along which the error of the reference value decreases; and an estimation step for estimating the number of residual persons through the dynamic neural network part adjusted in the neural network learning step, and proposes a technique of efficiently grasping persons in a room of a building. Thus, installation and maintenance costs can be cheaper than those of a conventional method for checking the number of persons in a room using video cameras or motion recognition sensors, and reliability can be improved by removing a dead zone.

본 발명은 탄화 폴리머가 표면에 코팅된 다공성 금속 폼으로 이루지는 흡착수단; 상기 흡착수단을 내부에 포함하는 튜브; 및 상기 튜브의 외면에 권선된 열선을 구비하는 가스분석 시스템용 마이크로 전농축기에 관한 것이다. 본 발명은 다공성 금속 폼을 사용하여 흡착수단의 표면적을 극대화하고 압력강하를 최소화할 수 있다. 이러한 다공성 금속 폼을 사용하여 넓은 표면적을 가지므로 분석가스의 높은 농축비를 보이며, 압력강하가 적어 휴대화에 용이하다. 또한 다공성 금속 폼은 열전도성이 우수하므로, 외부 열선을 통한 가열에 의한 분석가스의 신속한 탈착이 가능하다.

PURPOSE: An exhaust and suction grill for natural ventilation is provided to reduce the energy by performing the ventilation without excessively using a suction fan or an exhaust fan. CONSTITUTION: An exhaust and suction grill for natural ventilation comprises the intake wing(110), a cover(120), and a suction grill(100). The cover is installed at the upper of the intake wing. The wind blowing from every direction strikes against the intake wing and flows into a suction pipe(30). The suction grill is installed at the entrance of the suction pipe. An exhaust pipe is connected to the center of the ventilation passage of an exhaust grill. The width of the center of the ventilation passage of the exhaust air grill is narrow and becomes wider as the distance from the center is far. A damper(150) controlling the aperture ratio is installed at the back end of the intake wing.

Abstract:
PURPOSE: A modulated chamber for a hydrodynamic focusing operation is provided to prevent the leakage phenomenon of sample solutions or buffer solutions by fixing micro channels to a desired position in a micro chamber. CONSTITUTION: A modulated chamber includes a focusing module main body(10), a inlet side cover(20), and an outlet side cover(30). The focusing module main body includes a first channel and a second channel. A sample solution flows through the first channel. A buffer solution flows through the second channel. The inlet side cover is detachably arranged at the upper side of the inlet of the first channel. The outlet side cover is detachably arranged at the upper side of the outlet side of the first channel. The inlet side cover and the outlet side cover are combined with the focusing module main body to be in connection with the first channel and the second channel.
