Abstract: Chest motion associated with breathing is detected to obtain a breathing motion signal representing the chest motion in the form of an electrical signal; then, the times at which specific points occur in the waveform of the breathing motion signal are detected and, when the time interval between the specific points is within a predetermined range, the presence of a human body is detected in a vehicle.

Abstract: A device for and a method of measuring a blood flow of a living body having blood vessels that emit bio-photons and through which blood flows, the device including a detector positioned adjacent to a predetermined portion of the living body for measuring a bio-photon emission from the living body and a processor for analyzing and displaying the blood flow of the living body based on a value of the bio-photon emission.

Abstract: An apparatus for diagnosing sleep apnea, which detects a temporary cessation of breathing during sleep by applying light to a part of a subject's body and processing light output therefrom, includes a light source unit for sequentially generating light of at least two different wavelengths according to a control signal, a photodetecting unit for detecting the light, which are generated by the light source unit and applied to the body part, and for converting the detected light signals into electric signals, a diagnosis unit for substantially removing a time delay between the electric signals output from the photodetecting unit, for calculating a ratio between the electric signals, and for comparing the ratio with a predetermined reference value to diagnose sleep apnea, and a controller for outputting the control signal to the light source unit to generate the light signals, and for providing the predetermined reference value to the diagnosis unit.

Abstract: Provided are an apparatus and a method for recognizing positive/negative intention using a fine change of gamma wave of a brainwave comprising the steps of detecting the brainwave from a head of a user, receiving and amplifying the brainwave detected from the step of detecting the brainwave, converting the amplified analog brainwave to one of a digital type, and recognizing the positive/negative intention of the user by detecting the fine change of the gamma wave of the brainwave in the digital type, which is transmitted from the A/D converting portion, whereby it is possible to implement an application of a real time interface and minimizes inconvenience for the user, and it requires no separate user practice.
