  • Patent number: 10898135
    Abstract: A biometric information measurement device intermittently measures biometric information from a living body. The device includes an attachment and detachment determining section which determines whether the device is in an attached state where the device is attached to the living body or an unattached state where the device is detached from the living body, a personal identifying section which, in the attached state, determines whether a user attached with the device is a registered user who is registered in advance and stores a result of the determination, and a storage controller which, when a determination result indicating that the user is the registered user is stored, stores information indicating the registered user while being associated with the measured biometric information. The personal identifying section deletes the determination result when a time period in which the device is determined to be in the unattached state exceeds a predetermined time period.

  • Patent number: 10823035
    Abstract: An exhaust purification device includes a PM filter and a differential pressure sensor for the PM filter, and calculates a first estimated amount PMf based on the operating state of the internal combustion engine and a second estimated amount PMc based on the differential pressure. The exhaust purification device performs an anomaly determination of the differential pressure sensor based on the state of the differential pressure sensor from stopping of the internal combustion engine to a startup thereof, and corrects the first estimated amount PMf based on the second estimated amount PMc when starting the internal combustion engine. The exhaust purification device calculates, as the PM deposition amount Pr, the larger value of the first and second estimated amounts, and starts a filter regeneration control of the PM filter when the PM deposition amount Pr is equal to or more than a first predetermined amount.

  • Patent number: 10791940
    Abstract: A diagnosis assistance apparatus acquires a predetermined period's worth of biological information measured from a living body every heartbeat, from a storage unit storing the biological information, divides the biological information into multiple segments, generates fluctuating state information indicating the fluctuating state of the biological information in each segment, and displays a graph indicating the fluctuating state information of each segment on a display unit. Furthermore, if a certain piece of fluctuating state information is selected in the graph displayed on the display unit, the diagnosis assistance apparatus displays a graph indicating the biological information belonging to the segment corresponding to the selected piece of fluctuating state information on the display unit.
