摘要： PROBLEM TO BE SOLVED: To provide a sleep support device, a program, and a recording medium which support sleep itself without using a large-scale apparatus such as a sleep polygraph. SOLUTION: At step 110, the pulse wave is measured for one minute. The fluctuation component at around 0.3 Hz of the pulse intervals is calculated, and the obtained value becomes the initial value HF0 of the fluctuation component. At step 120, the pulse wave is measured sequentially at intervals of one minute. The fluctuation component HF at around 0.3 Hz of the pulse intervals is calculated from the measured pulse wave, and the ratio of the change to the initial value (or the rate of increase in the amount of activity of the parasympathetic nerves) HF/HF0 is displayed on a user interface 9. At step 130, whether HF/HF0 is greater than a prescribed value is determined. At step 150, since the state is presumed suitable for going to bed, the device urges a user to go to bed by displaying the state on the user interface 9. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a spygmographic sensor which can stably give a sphygmo gram and detect with high sensibility. SOLUTION: The pulse wave sensor 1 has a detecting section 2 and a sensor body 3 and both are respectively fixed to the back side of the wrist by means of belt 10 and 14 to be exclusively used. As a result, the mispositioning of the detecting section may be made small and the influence of the body movement may be made small and therefore a good signal-to-noise ratio may be assured. A light transmission plate 8 of the detecting section 2 is composed of a concavely curved surface on a front surface side which comes into contact with the human skin. As a result, the degree of the tight adhesion of the light transmission plate 7 to the skin surface is improved and therefore the infiltration of the reflected light quantity from the skin surface and the noise light, such as disturbance light, may be prevented. The pulse wave sensor of the high detection probability may be consequently realized. Further, sponge or buffer material 15 of a gelatinous type is inserted between a sensor body 3 arranged in superposition on the upper part of the detecting section 2 and the detecting section 2. As a result, the transfer of the force acting on the sensor body 3 and the movement of the sensor body 3 to the detecting section is made difficult.

摘要： PROBLEM TO BE SOLVED: To substantially precisely detect the information (peak interval of speed pulse wave) corresponding to the RR interval of an electrocardiogram from pulse waves by differentiating the pulse wave continuously measured for an optional fixed time to calculate a speed pulse wave, and setting the peak interval of the speed pulse wave to the pulse wave RR interval corresponding to the RR interval of the electrocardiogram. SOLUTION: A pulse wave sensor 2 to be mounted on the finger 1 of a human body comprises a light emitting element 3 and a light receiving element 4. The quantity of hemoglobin in a capillary 1a is changed in wave motion form by the wave motion of the blood, and the light absorbed by hemoglobin is also changed in wave motion form. Namely, since the light receiving quantity reflected by the capillary 1a and detected by the light receiving element 4 is changed, the change of the light receiving quantity is outputted to a pulse wave analyzing device as pulse wave information, wherein the pulse wave measured for a fixed time is differentiated to determine a speed pulse wave. The peak of the speed pulse wave to the pulse every beat is determined, the interval between the adjacent peaks is also determined, and a value of the threshold determined from the average value of each peak interval or more is set as the pulse wave interval.

摘要： PROBLEM TO BE SOLVED: To provide a ring-shaped pulse wave sensor to be used by closely attaching the detecting part to a finger without regard to the size of the finger and capable of preventing the detecting part from slipping. SOLUTION: A pulse wave sensor 1 is shaped in a ring and consists of a sensor main body 3 with a built-in circuit part 2, a detecting part 4 for detecting pulse wave data of a subject, a belt 5 for fixing the sensor main body 3 to a finger, etc. The sensor main body 3 and the detecting part 4 are flexibly connected to each other with a flexible printed circuit board 8. Therefore, since movement of the sensor main body 3 is hardly transmitted to the detecting part 4 and slipping of the detecting part 4 corresponding to movement of the body of the subject can be controlled, the movement-resisting pulse wave sensor 1 can be achieved. In addition, the sensor main body 3 can be fixed to a finger with the detecting part 4 pressed on the surface of the finger by adjusting the length of the belt 5, the pulse wave sensor 1 can be used with the detecting part 4 always closely attached to the finger without regard to the size of the finger.

摘要： PROBLEM TO BE SOLVED: To provide a pulse wave sensor capable of reducing noise light and enhancing detection probability. SOLUTION: For this pulse wave sensor 1, a light shielding member 6 is arranged between a light emitting element 3 and a light receiving element 4 housed in a package 2. Sometimes a part of light irradiated from the light emitting element 3 is reflected on the boundary of the surface of a light transmitting plate 5 and the skin surface of a finger F and returns to the light transmitting plate 5. For that, since the light shielding member 6 is arranged between the light emitting element 3 and the light receiving element 4 for the pulse wave sensor 1, the light reflected on the boundary among the light irradiated from the light emitting element 3 is blocked from entering the side of the light receiving element 4 from the light shielding member 6. As a result, the light reflected on the boundary is not directly made incident on the light receiving element 4 and the influence of reflected light is eliminated in the measurement of pulse waves.

摘要： PROBLEM TO BE SOLVED: To prevent the effect of noise light through a simple arrangement in a structure comprising an optical window member having noise light scattering characteristics. SOLUTION: An infrared image sensor 9 detects the temperature distribution of a predetermined region in a vehicle focused through a condenser lens 15. A signal detecting/processing circuit 19 generates a thermal image data based on the temperature distribution thus detected. A control circuit 23 for various systems operates various systems based on the heat image data thus generated. Although the condenser lens 15 has characteristics for scattering/cutting noise light, e.g. visible light, a scattering visible light may enter into the infrared image sensor 9. When the temperature detected by all thermal detection elements constituting the infrared image sensor 9 rises substantially uniformly, the signal detecting/processing circuit 19 makes a decision that a scattering visible light entered into the sensor 9 and invalidates an acquired data.

摘要： PROBLEM TO BE SOLVED: To securely detect the presence or absence and the position of a crew in a configuration for detecting the crew in a vehicle. SOLUTION: An infrared area sensor 3 detects the temperature distribution of a specific region in a vehicle room whose image is formed by a lens 4. A signal detection/processing circuit 8 creates thermal image data, based on the temperature distribution that is detected by the infrared area sensor 3. Then each kind of system control circuit 12 detects the position and skin temperature of a human body, based on the thermal image data that are created by the signal detection/processing circuit 8, thus appropriately operating an air bag system, an air-conditioning system, a security system, and the like. In this case, each kind of system control circuit 12 judges a crew with the environment outside the vehicle as a background due to the opening of a door, thus securing judging the crew even if the background temperature inside the vehicle room is close to the crew temperature.
