20090015839 | Living body optical measurement system - To make the peak value of the driving current of light source smaller than the conventional one and to make the peak value of the light receiving level of light-sensitive elements smaller than the conventional one in order to save power consumption of the device and to improve the precision of measurement, codes of which the bits of the Hadamard codes are shifted by the same bit for each code series having the same bit cycle, or codes of which the bits of a PN code are shifted are used as different codes. | 01-15-2009 |
20090054789 | Head-coupled holder for living body optical measurement - A head-coupled holder for living body optical measurement that securely brings a light irradiation module and a light detection module in close contact with a scalp, and gives the person to be examined no excessive pressure feeling. Each of the light irradiation module and the light detection module includes a contactor having a contact portion that comes in contact with a scalp of the person to be examined at a leading end thereof, and exposes a leading end of a light guide to the contact portion to form the light guide, and a package having a lower portion to which the contactor is attached. The contactor is fixed to the lower portion of the package through an elastic body, and the package is fixed to an inner upper wall of the insertion hole with a series structure of the elastic body and the viscoelastic body. | 02-26-2009 |
20090088616 | Ultrasonic Diagnostic Apparatus - There is provided an optical bioinstrumentation device, with which measurement data reflect more correctly the information inside the living body with less noise even the subject moves when the information inside the living body is measured by using the light. | 04-02-2009 |
20120245443 | BIOLOGICAL LIGHT MEASUREMENT DEVICE - The mental state, such as mood or emotion, of an individual can be apprehended by a method using non-invasive biological light measurement technology. A biological light measurement device, which has an irradiation section, presents different tasks (at least a first task and a second task) to a subject, hemoglobin signals based on changes in the concentration of oxygenated hemoglobin and deoxygenated hemoglobin in the subject are calculated from the strength of light detected by a detection section, and a relative value using the hemoglobin signal at a predetermined measurement channel with respect to the first task, and the hemoglobin signal at a different predetermined measurement channel with respect to the second task is calculated. | 09-27-2012 |
20130102907 | BIOLOGICAL PHOTOMETRIC DEVICE AND BIOLOGICAL PHOTOMETRY METHOD USING SAME - The present invention is capable of separating/removing the influence of skin blood flow contained in near infrared spectroscopy (NIRS) signals and extracting a brain- or brain cortex-origin signal. Moreover, the present invention enables versatile separation of brain-origin and skin-origin signals in view of differences among individuals. A biological photometric device, wherein light transmitters and light receivers are located in such a manner that measurement can be conducted at a plurality of source-detector (SD) distances and light received by the individual light-receivers can pass through the gray matter to thereby separate a brain-origin signal and a skin-origin signal. Individual component analysis (ICA) is conducted on data obtained at the individual measurement points. Then, it is determined whether each individual component originates in the brain or in the skin with the use of the SD distance-dependency of the weighted value of each of the separated components. | 04-25-2013 |
