  • Publication number: 20170153638
    Abstract: An acquirer of an autonomous mobile device acquires a value of level difference between a datum level and the device.

  • Patent number: 9018959
    Abstract: An insulating state detection unit is configured to perform failure detection for switches, which connect a flying capacitor to a sample hold circuit for acquiring a charge voltage and a ground potential, by using a failure determination threshold value according to a variable value. That is to say, the insulating state detection unit is configured to decide the failure determination threshold value by taking, as a reference, a charge voltage of a capacitor of the sample hold circuit charged with electric charge amount corresponding to a charge voltage of the flying capacitor when the flying capacitor is charged with electric charge amount corresponding to an output voltage of a DC power supply.

  • Patent number: 9000772
    Abstract: If a charge voltage of a read capacitor Ca measured by a microcomputer 15 is zero, the microcomputer 15 measures a charge voltage of the read capacitor Ca after the read capacitor Ca is discharged and is charged by a charge supply circuit 17 to predetermined potential, measures the same when the read capacitor Ca is isolated thereafter from a discharger of a flying capacitor C1, and measures the same when the read capacitor Ca is charged thereafter with a discharge voltage of the flying capacitor C1 just after the start of discharge of the flying capacitor C1. Based on a pattern of the charge voltage values of the read capacitor Ca measured at the respective time points, a fault location of the insulated condition detector 10 is identified.
