Abstract: A method and a system for recognizing a position using a sound source of a multiple frequency are provided to measure a 3D position by attaching three or more transmitters on the same plane. A synchronizing signal is generated in a plurality of ultrasonic wave satellites(200-a~200-n). Each satellite transmits an ultrasonic wave of a different frequency at the same time. A receiver of a moving body(100-a~100-n) receives the ultrasonic wave, classifies a frequency, and calculates a distance from each ultrasonic wave satellite. A present position of the moving body is calculated based on the calculated distance.

Abstract: An apparatus and a method for constituting a character by a teeth-clenching are provided to allow the serious disabled to communicate with information terminal such as a cell phone and a computer through a message by inputting the character through left and right clenching operations. In an apparatus for constituting a character by a teeth-clenching, an electromyogram signal obtaining unit(10) has an electromyogram sensor(100) which is placed at both sides and generates an electromyogram signal according to an activation of muscle during a clenching operation to clench teeth and a ground electrode(110) which supplies a standard voltage by being contacted with a human body. An electromyogram signal processing unit(20) outputs the relative characters generated through a selective input of the characters by recognizing a teeth-clenching pattern of each block, corresponding to the teeth-clenching operation including a teeth-clenching position, a teeth-clenching duration, and a teeth-clenching continual operation with respect to the electromyogram signal which is transmitted from the electromyogram signal obtaining unit(10).

Abstract: PURPOSE: A brain bio-feedback system and a controlling method thereof are provided to extract pure brain wave elements and display a measured value by separating elements of stability from brain wave signals. CONSTITUTION: A brain wave sensing unit(10) measures brain waves of four channels by using an electrode sensor of a head band and converts the brain waves to electric signals. A brain wave element extraction unit(20) separates the brain wave signals of four channels into four independent elements. A signal processing unit(22) produces an alpha wave spectrum of a pure brain wave from the independent elements. A display(26) outputs a measuring result of a brain wave according to an alpha wave spectrum ratio to graphics or data values. An auditory driving unit(28) provides an auditory stimulus to a testee. A microprocessor(24) is used for perform a control operation for outputting the measured result to the display and operating the auditory driving unit according to the measured result.
