  • Publication number: 20210108549
    Abstract: A vehicle includes a battery and a CO2 recovery device using electric power of the battery to recover CO2 contained in inflowing gas. A control device mounted in the vehicle controls the CO2 recovery device. The control device permits operation of the CO2 recovery device in the case where a high efficiency recovery condition, at which it is predicted that the efficiency of recovery of CO2, showing a ratio of the amount of recovery of CO2 in the CO2 recovery device with respect to the electric power consumed by the battery, will become equal to or greater than a preset predetermined efficiency, is satisfied, and prohibits operation of the CO2 recovery device in the case where the high efficiency recovery condition is not satisfied.

  • Patent number: 10426371
    Abstract: An object of the present disclosure is to provide a muscle condition measurement sheet that can quantitatively detect the amplitude and latency of an evoked electromyogram EMG or an evoked mechanomyogram MMG and correctly evaluate the state of activity of a muscle. A pair of stimulating electrodes and all myoelectric detection electrodes come into intimate contact with a body surface of a muscle, appearing on a back surface of an insulating sheet spaced at predetermined intervals; accordingly, the relative position between an electrical stimulation position and the myoelectric detection electrode is fixed and the amplitude and latency of the evoked electromyogram EMG can be quantitatively detected without depending on the stimulation position of an electrical stimulation signal.
