A technique may be provided to determine, as a target breathing rhythm used to change a mental and physical state of a target person to a target mental and physical state, not only an exhalation period for exhaling and an inhalation period for inhaling, but also a grace period between the exhalation period and the inhalation period. The grace period is a switching period between the exhalation period and the inhalation period. The grace period is a period in which exhalation, or inhalation, or both exhalation and inhalation are enabled to be performed.

A device for measuring concentration of a constituent in blood includes: an irradiation unit for irradiating light toward a living body, the light having a wavelength disposed in a light absorption band of the constituent in the blood; a light receiving unit for receiving light, which is reflected in the living body or transmitted through the living body; and a concentration measurement unit for measuring the concentration of the constituent in the blood based on variation of light intensity of light received by the light receiving unit, the variation attributed to a pulse wave of the living body.

Device for measuring concentration of constituent in blood and measuring method

When a driver of a vehicle brings his/her detection part close to a case, a sensor detects a pulse of the driver at the detection part with an optical method, and takes an image of the detection part. An individual certification means determines whether the driver of the vehicle is an authorized person or not based on the image of the detection part taken by the sensor. An alcohol concentration determiner calculates an index value of a blood alcohol concentration of the driver based on the pulse detected at the detection part by the sensor, and determines whether the index value exceeds a criterial value of a drinking assessment. When it is determined that the driver of the vehicle is an authorized person and the index value does not exceed the criterial value of the drinking assessment, a permission means permits the driver to start an engine of the vehicle.

A blood constituent concentration detector includes: a detection portion having an optical window for measuring a blood constituent concentration of a part of a living body in an optical manner when the part of the living body is pressed on the detection portion; a load determination element for determining whether a load to the detection portion is equal to or larger than a first threshold, and smaller than a second threshold, wherein the second threshold is larger than the first threshold; and a measurement element for measuring the blood constituent concentration when the load determination element determines that the load to the detection portion is equal to or larger than the first threshold, and smaller than the second threshold.

A particulate concentration detector including a detection mechanism having a light emission unit and light reception unit. The particulate concentration detector detects the concentration of particulates suspended in a liquid from the light amount detected by the detection mechanism. The detection mechanism includes a first light guide, a second light guide, a liquid chamber, and a third light guide. The first light guide is arranged at a location facing toward a light emission surface of the light emission unit. The second light guide is arranged at a location facing toward a light reception surface of the light reception unit. The liquid chamber is formed between the first light guide and second light guide and allows the liquid to flow therein. The third light guide is arranged in an oscillatable manner in the liquid chamber so as to face toward the first light guide and the second light guide.

It is an object of the present invention to provide a fuel property detection apparatus that excels in durability and reliability and is capable of accurately detecting the biofuel concentration in a mixture of hydrocarbon fuel and biofuel with a compact and simple configuration. A fuel property sensorincludes a light-emitting deviceand a light-receiving device, which detect the optical transmittance of a fuel in a fuel path; and a light-emitting deviceand a position sensitive device, which detect the refractive index of the fuel. As the optical transmittance correlates with the RME concentration of the fuel, the RME concentration can be calculated from the detected optical transmittance. As the refractive index correlates with the cetane number of the fuel, the cetane number can be calculated from the detected refractive index. The optical transmittance is detected through the use of light within a wavelength range of 640 nm to 680 nm.

Fuel property detection apparatus

A device for controlling an internal combustion engine which uses, as the fuel, a heavy fuel, a light fuel, an alcohol fuel and a mixture thereof, comprising a heavy fuel/light fuel ratio detectorcapable of detecting the ratio of the heavy fuel and the light fuel, and an air-fuel ratio detectorfor detecting the air-fuel ratio of the exhaust gas, wherein the amount of fuel injection is calculated based on the heavy fuel/light fuel ratio detector so that the air-fuel ratio becomes a target air-fuel ratio. The heavy fuel/light fuel ratio detector is diagnosed if it is in an abnormal condition based on a difference between the target air-fuel ratio and the air-fuel ratio detected by the air-fuel ratio detector while the engine temperature is in a particular temperature region. The heavy fuel/light fuel ratio detector can be correctly diagnosed if it is in an abnormal condition even when an alcohol-mixed fuel is used.

A fuel property sensor is provided with three bypass passages and a measure passage. The measure passage is located inside of a closed loop which is comprised of common tangential lines of adjacent bypass passages and a part of profile line of each bypass passage in a cross section perpendicular to the measure passage. Even if the fuel property sensor is rotated around the axis of a fuel pipe in assembling the fuel property sensor to the fuel pipe, at least one of two bypass passages is always located above the measure passage in a vertical direction. Hence, bubbles included in the fuel are restricted from flowing into the measure passage. The fuel property sensor can detect the concentration of ethanol contained in the fuel with high accuracy.

An apparatus for detecting the concentration of particles in a liquid includes a light-emitting portion for emitting examination light which is totally reflected-by a boundary surface contiguous to the liquid to be examined, a photosensor for receiving the totally-reflected light, a reference sensor for directly receiving the examination light, and a judgment portion for finding the reflectance from outputs of the two sensors to compute the particle concentration. In case that the liquid to be examined is lubricating oil of an engine, the concentration of carbon particles is calculated, thereby judging the deterioration of the lubricating oil.
