摘要： Disclosed herein is a direct current (DC) uninterruptible power supply system. The DC uninterruptible power supply system is connected to a DC power conversion system converting prevailing alternating current (AC) power into DC power, supplies the DC power to a load, charges an internal auxiliary power supply device with the DC power, and continuously supplies power to the load from the auxiliary power supply device while cutting off an electric connection with the DC power conversion system when the DC power conversion system short-circuits due to a leakage current or damage thereof or is disconnected.

摘要： A semiconductor device stabilizes an operation of an input buffer. A semiconductor device includes an input potential detection unit, an input buffer, and a current sink unit. The input potential detection unit outputs a detection signal in response to a level of an input signal. The input buffer buffers the input signal by differentially amplifying the input signal through a first current sink unit. The current sink unit receives the detection signal, and in response to the detection signal, performs an auxiliary differential amplifying operation with respect to the input signal buffered by the input buffer.

摘要： The present invention relates to a drowsiness detection method. A heartbeat signal and a breathing signal are detected by exploiting together a scheme and an optical system scheme. The detected signals are applied to respective amplification units, noise signals are eliminated from the detected signals, and noise-free signals are amplified. The amplified signals are applied to a central processing unit, signal processing is processed on the signals, and processed signals are combined. The combined signal is counted, and a warning sound, voice message or vibration is output in a case where a value, obtained by subtracting a counted output value monitored one minute before a current time, from a counted output value monitored two minutes before the current time, falls within a detection range and where, with a passage of time, the value falling within the detection range is successively detected from two to ten times.
