According to the method of the present invention for plotting a fluctuation waveform as coordinate points on a four-quadrant coordinate system on the basis of the predetermined standard, change in the fluctuation waveform of the ultra-low-frequency band can be expanded or highlighted and thus perceived, and therefore the present invention is adapted for more accurately perceiving change in a person's status. | 12-18-2014 |
20140339878 | BASE NET AND SEAT STRUCTURE - A base net for a back is formed from a three-dimensional stereoscopic knit, and has a configuration in which seams for bringing a pair of ground knitted fabrics thereof to close to each other in a thickness direction are partially provided, predetermined preliminary compression is applied in the thickness direction by the seams, and thereby residual stress is generated in a surface direction (stretching direction). Therefore, stiffness is partially increased by partial improvement in residual stress, and consequently a human body with extreme roughness is supported by nearly uniform pressure. Thus, in spite of a simple configuration in which the seams are provided in desired regions, posture supportiveness and body pressure dispersiveness can be improved. Further, by arbitrarily adjusting the formation positions of the seams, the pressure distribution is adjusted, thereby making it possible to easily control the vibration mode to desired setting, and easily improve vibration absorbency. | 11-20-2014 |
20140317931 | MANUFACTURING METHOD FOR SEAT FRAME STRUCTURE - A predetermined component such as a recliner is attached to a long member in advance, and thereafter by bending the long member, a pair of side frames and an upper frame are integrally formed. Therefore, the recliner can be attached to the long member not bent yet and thus in a substantially flat state, and in addition, the pair of side frames and the upper frame can be integrally formed, which does not require labor and contributes to a reduction in manufacturing cost. Moreover, by adjusting a position where the bending is performed, it is possible to manufacture seat frame structures different in dimension even if the long members not bent yet have the same length, and from this viewpoint as well, it is possible to reduce labor and manufacturing cost. | 10-30-2014 |
20140300123 | UPPER FRAME POSITION HOLDING STRUCTURE AND AMBULANCE VIBRATION-PROOF RACK HAVING UPPER FRAME POSITION HOLDING STRUCTURE - An upper frame swingable between an inclined posture and a substantially horizontal posture along a trajectory of movement of a four-bar linkage is held in the substantially horizontal posture by a simple operation when necessary. A front link mechanism control gives an external force for pushing down an operation member to thereby control a front link mechanism so as to displace the upper frame rearward while lowering a front side of the upper frame. Since a displacement direction for bringing the upper frame into the substantially horizontal posture and an operation direction for locking the front link mechanism or a rear link mechanism by the operation of the operation member are substantially the same direction, it is possible to perform two movements, the displacement movements to the substantially horizontal posture and the locking movements, only by operating the operation member in a predetermined direction. | 10-09-2014 |

The technique determines a time-series waveform of a frequency from a time-series waveform of a biological signal acquired from an upper body of a human being, and determines time-series waveforms of a frequency slope and frequency variation to analyze these frequencies. Upon analyzing the frequencies, it determines power spectrums of frequencies corresponding to a preset functional adjustment signal, fatigue reception signal, and activity adjustment signal, and then determines a state of the human being from a time-series change in each power spectrum. Dominant degrees of the functional adjustment signal and activity adjustment signal are compared as distribution rates thereof, in addition to a degree of progress of fatigue, to determine a state of the human being, for example a relaxed state, fatigued state, prominent state of sympathetic nervous, prominent state of parasympathetic nervous. | 08-29-2013 |

The technology is provided with means for acquiring a time-series waveform of a frequency from a time-series waveform of a biological signal sampled from the upper body of a human being and for further acquiring a time-series waveform of frequency slope and a time-series waveform of frequency fluctuation and for applying frequency analysis to them. In the frequency analysis, a power spectrum of each frequency corresponding to a functional adjustment signal, a fatigue reception signal, and an activity adjustment signal, respectively, determined in advance is acquired. Then, a state of a human being is determined from a time-series change of each power spectrum. The fatigue reception signal indicates a degree of progress of fatigue in a usual active state and thus, by comparing it with degrees of predominance of the functional adjustment signal and the activity adjustment signal as their distribution rates, a state of a human being (relaxed state, fatigued state, state in which sympathetic nerve is predominant, a state in which parasympathetic nerve is predominant and the like) can be determined more accurately. | 01-31-2013 |
20120259181 | BIOLOGICAL STATE ESTIMATION DEVICE, BIOLOGICAL STATE ESTIMATION SYSTEM, AND COMPUTER PROGRAM - A biological body state estimation device configured such that a homeostatic function level is sorted and acquired in plural stages by using a biological signal obtained from an upper body of a person and each stage of the homeostatic function level is plotted in time series in accordance with a time axis indicated on the lateral axis and displayed as a graph by a display. A highest part on the vertical axis of the graph can be displayed as a highly active state and a lowest part as a function decline state. Therefore, a state of fluctuation due to autonomous nerves as an attempt to maintain homeostasis, progress of a feeling of fatigue, and a state stimulated by activation of the brain can be captured as a periodic function.

Thereby, the structure can easily deflect in the right-and-left direction. Therefore, since an impact load larger than a predetermined level inputted in the front-and-rear direction due to front-and-rear/pitching vibration or a rear collision and the like becomes a force of deflecting the back frame in the right-and-left direction, the vibration/impact energy is consumed by that, and moreover, rearward displacement of the back frame consumes vibration/impact energy. Thus, absorbing performances of the vibration/impact energy are higher than before. | 08-30-2012 |

By comparing changes of two waveforms with each other in a waveform determining device, a state change of a person can be captured with timing closer to consciousness of the person. A sleep-onset point can be specified clearly based upon the case where a fluctuation waveform steep gradient portion indicating a steep gradient change emerges in the frequency fluctuation waveform, and amplitude and a base line position of the frequency fluctuation waveform or the frequency slope waveform are in predetermined ranges. Further, when a mean slope line of the fluctuation waveform steep gradient portion is approximately parallel to a mean slope line of the slope waveform steep gradient portion in the frequency slope waveform before emergence of the fluctuation waveform steep gradient portion, a sleepiness waveform is determined, so that a sleepiness state leading to sleep onset can be detected. | 04-26-2012 |
