  • Publication number: 20190307336
    Abstract: A pulse wave measurement device includes: a belt to be attached around a measurement site; first and second pulse wave sensors which are mounted on the belt in a state of being spaced apart from each other in a width direction of the belt and detect pulse waves at portions of an artery passing through the measurement site, the portions individually facing the first and second pulse wave sensors; and a pressing member capable of pressing the first and second pulse wave sensors against the measurement site while varying a pressing force. First and second pulse wave signals which the first and second pulse wave sensors output respectively in a time series are acquired, and a cross-correlation coefficient between waveforms of the first and second pulse wave signals is calculated.

  • Publication number: 20190307340
    Abstract: A belt to be mounted around a measurement site; first pulse wave sensor and second pulse wave sensor mounted on the belt, separated from each other, configured to detect pulse waves in an artery passing through the measurement site; and pressing member mounted on the belt, capable of pressing first pulse wave sensor and second pulse wave sensor against the measurement site while varying pressing force. Time difference between first and second pulse wave signals is acquired as pulse transit time. Blood pressure is calculated based on the pulse transit time acquired by the measurement processing unit by using a predetermined correspondence equation between pulse transit time and blood pressure. Pulse transit time is acquired with the measurement processing unit while pressing force by pressing member is changed in resting state, and corresponding equation is calibrated based on plurality of pulse transit times corresponding to plurality of respective pressing forces.

  • Publication number: 20190301917
    Abstract: First to eighth laser measurement sections (30a) to (30h) of a laser measurement unit (30) measures a height of a surface of powder resins (15) in a coil insertion range CA for every angular degree in a circumferential direction of a stator core (2). A control unit (18) computes the number of points where the height of the surface is lower than a predetermined height among measurement results at multiple points measured by the first to eighth laser measurement sections (30a) to (30h), where the number of points is defined as an index value indicative of a dispersion of the measurement results. When it has been determined that the index value exceeds a first predetermined value, a notification is issued by outputting from a speaker (32) a sound indicative of the fact that the index value that has been computed exceeds the first predetermined value.

  • Publication number: 20190265618
    Abstract: An image forming apparatus connected to a charging device includes an image forming unit, a fixing unit, a charge processor, a controller, and a printed sheet counter. The charge processor charges a fee for printing. The controller selects an energy saving mode, upon deciding that a balance of a deposited amount in the charging device is less than a threshold amount. The printed sheet counter counts the number of sheets of the recording medium printed by the image forming unit in one single printing job. The controller selects the energy saving mode for the next printing job, upon deciding that the number of sheets printed in one single printing job is less than a predetermined threshold number of sheets, when the deposit balance is remaining in the charging device.

  • Patent number: 10385752
    Abstract: An amount of reducing agent adsorbed on a NOx catalyst when a reducing agent supply device is normal and a corresponding detected value may be estimated. The corresponding detected value may be detected by a NOx sensor, and the detected value may correspond to an amount of reducing agent adsorbed on the NOx catalyst. When the estimated amount of adsorption is larger than or equal to a first amount and is smaller than or equal to a second amount, a diagnosis of the NOx catalyst based on the detected value of the NOx sensor may be prevented. The first amount may be an amount of adsorbed reducing agent corresponding to a minimum value of the corresponding detected value. The second amount may be an amount of adsorbed reducing agent corresponding to the corresponding detected value when the amount of adsorbed reducing agent is zero and larger than the first amount.
