  • Publication number: 20180199839
    Abstract: An intraoral pressure signal is associated with a pulse wave signal along a time axis. As a calibration coefficient, a ratio of a variation in an amount of change in an amplitude of the pulse wave signal from a preset second reference value to a variation in an amount of change in the intraoral pressure represented by the intraoral pressure signal from a preset first reference value is calculated based on the acquired pulse wave signal and the acquired intraoral pressure signal. An absolute value of an intrathoracic pressure of the subject is calculated by multiplying an estimated intrathoracic pressure, which is a relative value of the intrathoracic pressure estimated based on the pulse wave signal, by the calibration coefficient.

  • Patent number: 8469134
    Abstract: 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.

  • Patent number: 7764360
    Abstract: 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.
