Abstract:
PURPOSE: A bio-signal transmission device, a vehicle control device, a vehicle automatic control system using the same, and a method thereof are provided to control driving of a vehicle by handling emergency situation happening during driving. CONSTITUTION: A bio-signal transmission device(100) comprises a bio-signal measurement unit(110), a signal processing unit(120), and a transmission unit(130). The bio-signal measurement unit measures a bio-signal of a driver. The signal processing unit filters the bio-signal measured in the bio-signal measurement unit and removes noise. The signal processing unit amplifies the bio-signal in which the noise is removed and converts the amplified bio-signal into a digital signal for output. The transmission unit wirelessly transmits the digital signal. [Reference numerals] (110) Bio-signal measurement unit; (120) Signal processing unit; (130) Transmission unit
Abstract:
Disclosed is a light source output device capable of increasing the output of a light source. The light source output device includes a pulse generator which generates a plurality of optical pulses; a pulse distributor which distributes the optical pulses generated by the pulse generator on a time domain; and an optical coupler which makes the distributed optical pulses to progress in one path. Also, the light source output device further includes an optical amplifier which amplifies the output amplitude of the optical pulses outputted from the optical coupler; a pulse separator which separates the optical pulses amplified by the optical amplifier by corresponding wavelength; and a time delay unit which delays each of the optical pulses separated by wavelength to reach a coupling point at the same point of time. The pulse coupler generates a strengthened optical output by combining the optical pulses which reach the coupling point at the same point of time.

PURPOSE: A bio-signal transmitting device, a bio-signal monitoring system using the same, and a method thereof are provided to offer the information of a user about a physical state, degree of urgency, and location. CONSTITUTION: A bio-signal monitoring system (100) includes a bio-signal transmitting device (1100), receiving device (1200), and monitoring server (1300). The bio-signal transmitting system measures and analyzes a big-signal and transmits the analyzed bio-signal and first identification data. The receiving device includes at least one receiver, and each receiver transmits the data sent by the bio-signal transmitting device and second identification data. The monitoring server analyzes the data received by each receiver, and identifies the location and physical state of a user. The first identification data includes a user identification and a bio-signal identification. The second identification data includes a receiver identification.
