Abstract: PURPOSE: A human body's balancing function diagnostic system and a method thereof are provided to quantitatively estimate the balance maintaining capabilities of the human body of a diagnostic subject by using the rate of change in the individual value of a normal person and an abnormal person. CONSTITUTION: A disturbance driving unit(10) sanctions a fixed level of disturbance to a diagnostic subject in an upright position. A sensor(20) acquires the changing data on angles by detecting a variation in the angles of human joints for coping with disturbances and maintaining balance. A balancing function output unit(30) produces the balancing function of a diagnosis subject based on the size of a disturbance and the data on angles detected from the sensor. The disturbance driving unit comprises a platform(11), a platform driver(13), and a ground reaction force(15). A diagnosis subject is positioned on the platform in an upright position. The platform driver drives the platform to the fixed level of disturbance. The ground reaction force transfers a drive torque to the balancing function output unit by measuring the drive torque of the platform.

Abstract: A method for measuring a gain of a VCO(Voltage Controlled Oscillator) and a frequency synthesizer are provided to decrease power consumption of the frequency synthesizer by stopping the operation of a measuring loop and a calibration unit at a normal mode. A frequency synthesizer includes an oscillator(240), a main loop(210), and a measuring loop(220). The oscillator generates an oscillation signal having a frequency corresponding to a magnitude of a control signal. The main loop is activated at a normal mode, and receives the oscillation signal. The main loop compares the oscillation signal with a first reference signal, generates the control signal according to the compared result, and provides the control signal to the oscillator. The measuring loop is activated at a measuring mode, and receives the oscillation signal. The measuring loop sequentially changes the frequency of the oscillation signal by a predetermined amount and provides the control signal to the oscillator according to the frequency of the oscillation signal.

A folding mirror(60) is disposed in the advancing direction of another splitted beam. A piezo-electric driver(52) is connected to the reference mirror for the micro control of a distance between the reference mirror and the beam splitter. The beam reflected to the folding mirror is incident to an optical axis(z) of the second lens fixed to the base. Another folding mirror is disposed to a bottom surface of the second lens for obtaining a beam reflected from a detection surface. A CCD camera(70) is disposed around the beam splitter for photographing the interference pattern of the beams coming from the reference and folding mirrors.

Abstract: An apparatus and a method for transceiving an MPEG4 object using an MPEG2 TS are provided to remove a PMT(Program Map Table) and time decoding in each transmitted stream, thereby managing an AU efficiently in all streams. An apparatus for transmitting an MPEG4(Moving Picture Experts Group4) object using an MPEG2 TS(Transport Stream) comprises an AU(Access Unit) composition unit(3-2), a synchronization unit(3-4), a segment unit(3-9), and a TS multiplexing unit(3-6). The AU composition unit synthesizes plural multimedia Aus and BIFS(Binary Format for Scenes) simultaneously received. The synchronization unit adds an SL(Sync Layer) header to an AUC(Composite Access Unit) to generate an SL packet. The segment unit segments the SL packet. The TS multiplexing unit multiplexes the segmented SL packet with IOD/OD(Initial Object Descriptor/Object Descriptor) and PSI(Program Specific Information) to generate a TS packet. The TS packet includes a TS header. The TS header includes packet type information indicating which is included to the TS packet out of the segmented SL packet, the IOD/OD, and the PSI.
