摘要： PROBLEM TO BE SOLVED: To obtain the degree of fatigue closer to a sensory evaluation value by considering compensation by a sympathetic nerve activity. SOLUTION: The device is provided with a correction power value calculating means 222 for adding into compensation by the sympathetic nerve activity as a correction element of the power value instead of using a power value as it is which is obtained by biological signal data sampled by a photoplethysmogram pulse wave meter 11 and, after the correction power value is obtained, the correction power value is used to obtain the degree of fatigue. Thus, in comparison with the degree of fatigue measured by a conventional procedure using the power value, mental fatigue compensated by the sympathetic nerve activity is considered as well, so that the degree of fatigue to be obtained is closer to the sensory evaluation value, that is, closer to a real sense of fatigue.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for evaluating a comfort level for appropriately evaluating a human body supporting structure by quantifying a comfortable feeling and by a combination of the comfortable feeling and a feeling of fatigue. SOLUTION: Time series waveforms of a slope of heart beat fluctuations are acquired by a time series waveform calculating means 21 based on biological signals collected by a biological signal measuring device 10, and are subjected to a frequency analysis by a frequency slope calculating means 22. A slope to frequencies of spectra is calculated by extracting frequency components belonging to a VLF (very low-frequency) band containing a peak value of muscle fatigue signals or a ULF (ultralow-frequency) band containing a peak value of signals of signs of initiating sleep and by displaying the spectra in double logarithm. A comfort level determining means 23 quantifies the slope as the comfort level depending on whether the slope is closer to 1/f 0 , 1/f, or 1/f 2 . The mental and physical state of a person (a person who is supported) supported by the human body supporting structure is minutely and accurately determined by catching the transitions of the slopes of the fatigue level and the comfort level.

摘要： PROBLEM TO BE SOLVED: To provide an art for further accurately acquire the state of a person.
SOLUTION: This biological state estimation apparatus includes a means for acquiring a time-series waveform of a frequency from a time-series waveform of a biological signal collected from the upper body of a person and finding a time-series waveform of the frequency gradient and a time-series waveform of the frequency variation to perform frequency analysis thereof. In the frequency analysis, this apparatus acquires power spectra of the respective frequencies corresponding to a predetermined function adjustment signal, fatigue reception signal and activity adjustment signal. The state of the person is thus determined from the time-series changes in the respective power spectra. The fatigue reception signal indicates a progressing degree of the fatigue in an ordinary active state and, in conjunction therewith, priority degrees of the function adjustment signal and the activity adjustment signal are compared as their distribution rates, so as to accurately determine the state of the person (a relaxed state, a fatigue state, a sympathetic-nerve predominant state, a parasympathetic nerve predominant state, or the like).

摘要： PROBLEM TO BE SOLVED: To provide a muscle fatigue evaluation system suitable for evaluation of fatigue of accumulated work such as driving by evaluating myogenic potentials of muscles whose glycolytic ability is low. SOLUTION: The device has a data processing/judging means 20 which processes signal data obtained from a myogenic potential detection sensor 10 and which generates a fluctuation waveform of the signal data. It is difficult to obtain myogenic potential data having significant difference between a case of muscle fatigue and the other cases from the muscle whose glycolytic ability is low. However, the data processing/judging means 20 generates the fluctuation waveform in which the obtained signal data are emphasized, so that the occurrence of the muscle fatigue of the muscles whose glycolytic ability is low can be detected. As the result, the muscle fatigue evaluation device is suitable for the evaluation of fatigue of accumulated work such as driving. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To restore a driver to wakefulness as certain as possible, on detecting a transitional signal to hypnagogic state. SOLUTION: A seat system for a driver's seat comprises a driving-watching device 1 which watches the driver's biomedical state and a wakefulness-restoring device 30 which works by receiving the transitional signal to hypnagogic state while energy metabolism changes from an active state to a sleep state from the driving-watching device 1 to restore the driver to wakefulness. The wakefulness-restoring device 30 generates shearing stresses by tilting the seat back of the driver's seat forward or backward in order to stimulate driver's baresthesia. Consequently, the driver can be stimulated and restored to wakefulness more certainly without regard to reactivity to an alarm. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide more precise decision of a transitional signal to hypnagogic state while energy metabolism in vivo changes from an active state to a sleep state. SOLUTION: In a living body evaluation system 1, a living body signal analyzer 20 is equipped with a peak value detector of living body signal 23 which detects a peak value in each period of original waveform in living body signal data and with a power value calculator 24 which calculates difference between the maximum and minimum peak values every range of predetermined time from each peak value obtained by the peak value detector of the living body signal 23 and which sets the difference as a power value. The living body evaluation system 1 compositionally decides the transitional signal to hypnagogic state while energy metabolism in vivo changes from an active state to a sleep state, on the basis of change in time series of the power value. A new living body evaluation system other than conventional living body evaluations of which the indicator is only the Lyapunov index can be provided, wherein an active state in an anergy-generating system in vivo is perceived.

摘要： PROBLEM TO BE SOLVED: To achieve weight reduction and improve various functions such as shock absorption and vibration absorption.
SOLUTION: The seat is provided with a torsion bar 15 placed along in the cross direction, and an arm 16 connected to the torsion bar 15 and energized for a backward tilting direction, at the back of seat section 10. A cushion member 20 is stretched between a support frame 12 supported by the arm 16 and a front frame 13 provided in the front part of seat section with a front end rim 13a arranged so as to be turned up and down. By this structure, shock absorption function by means of moment of rotation around a hipbone node under heavy load can be attained more effectively, and the fitting of cushion member at the user's posture in which rump bone is in contact with the seat is improved. When the user is operating a pedal or is getting up, the front end rim 13a of the front frame 13 is forced to move in lower direction by the leg part, and a buttock support part of the cushion member is raised relatively. Accordingly, supporting power for lifting the buttocks is attained.
