Abstract: A health care apparatus and method are provided. The apparatus includes: a motion sensing unit; a bio-electric potential sensing unit sensing an electric potential signal of the health examinee corresponding to the sensed result; and an analysis unit analyzing the sensed result. By recognizing a current motion of the examinee and sensing an electric potential signal corresponding to the recognized current motion from the examinee, a more reliable health index of the examinee can be calculated. Even when information on the current motion of the health examinee is not given, the current motion can be recognized by the apparatus and method. Furthermore, since the health examinee is notified of the calculated health index in real time, the health examinee can be informed immediately if the physical condition is in an emergency state. As a result, the examinee can respond quickly to the emergency situation.

Abstract: An analyzing method and system includes projecting light onto a specimen, detecting an optical spectrum from the specimen, dividing the detected optical spectrum by a predetermined time interval, applying a weighting vector and a gain and offset vector to the divided spectra to generate a resolution vector, quantizing an analog signal of the resolution vector to a digital signal, and applying a synthesis vector to the quantized spectra to restore the quantized spectra to a size of the optical spectrum. A spectrum having a large amplitude difference is temporally divided and is analyzed by applying different resolutions to individual time intervals. Spectral portions of the spectrum having relatively small peak amplitudes are selected as a region of interest (ROI) to be modified.
