Abstract: Provided is a curvature-adjustable endotracheal tube. The curvature-adjustable endotracheal tube includes: a hollow cylindrical tube body configured to maintain a patient's airway; and a curvature-adjusting wire configured to allow an operator to freely adjust the curvature of the tube body to correspond to the curvature of the patient's airway into which the tube body is inserted. Both ends of the curvature-adjusting wire are respectively fixed to a distal portion and a proximal portion of the tube body such that the distal portion is pulled and bent when the proximal portion is bent by the operator.

Abstract: A method of removing noise from a two-channel signal includes receiving channel signals constituting the two-channel signal; obtaining a noise signal for each channel by removing a target signal from each channel signal by subtracting another channel signal multiplied by a weighted value from each channel signal; estimating a power spectral density (PSD) of diffuse noise from each channel signal; obtaining a target signal including an interference signal for each channel by removing the diffuse noise from each channel signal using the estimated PSD of the diffuse noise; obtaining the interference signal for each channel by removing the diffuse noise from the noise signal for each channel using the estimated PSD of the diffuse noise; and removing the interference signal from the target signal and the interference signal for each channel.

Abstract: A calibration apparatus for a wheelchair dynamometer include a body, a motor, a sensor, a wheel and a controller. The motor may be installed at the body to generate a torque. The sensor may be configured to measure a torque or a revolution per minute (RPM) generated from the motor. The wheel may be rotated by the torque. The controller may be configured to control the torque or the RPM generated from the motor and display a torque or a RPM measured by the sensor.

Abstract: An eyeball cooling module includes a cooling device and a heat dissipation unit. The cooling device generates a cooling stimulation to human eyeballs by absorbing heat from a first side in which the human eyeballs are disposed and dissipating heat to a second side opposed to the first side. The heat dissipation unit is disposed at the second side of the cooling device, and dissipates heat from the second side of the cooling device externally. Accordingly, cooling stimulation to eyeballs of a human may be generated to human eyeballs, fatigue of eyes and eyeballs may be relieved at home and eyeball fever may be reduced at hospitals.

Abstract: A speech signal processing apparatus and a speech signal processing method for enhancing speech intelligibility are provided. The speech signal processing apparatus includes an input signal gain determiner to determine a gain of an input signal based on a harmonic characteristic of a voiced speech, a voiced speech output unit to output a voiced speech in which a harmonic component is preserved by applying the gain to the input signal, a linear predictive coefficient determiner to determine a linear predictive coefficient based on the voiced speech, and an unvoiced speech preserver to preserve an unvoiced speech of the input signal based on the linear predictive coefficient.

Abstract: Disclosed is an apparatus for measuring a shearing force upon sitting in a seat in a vehicle. The apparatus includes a shearing force sensor, a signal processor, and a monitoring device. The shearing force sensor is disposed in a compartment in a seat and senses the shearing force generated upon sitting on the seat. The signal processor filters and amplifies a signal from the shearing force sensor 10, and converts an amplified analog signal into a digital signal. The monitoring device analyzes the signal converted by the signal processor and displays the signal. As a result, the apparatus measures all directions of shearing forces generated upon sitting.
