  • Patent number: 11970827
    Abstract: A sheet-shaped magnetic marker (1) to be laid on a road surface so as to be able to be detected by a magnetic sensor attached to a vehicle to achieve assist for driving operation of the vehicle by a driver or control on a vehicle side to achieve automatic driving independently from operation of the driver is divided into a plurality of regions in a matrix shape by a cut line (1C) cutting a magnet sheet (11) and a nonskid layer (181), with an adhesive layer being left. Thus, if peeling partially occurs, a region including the peeled part can be isolated, and expansion of peeling can be prevented.

  • Publication number: 20230146550
    Abstract: An adjustment system causes a target power supply device to execute first processing and second processing while causing at least one adjacent power supply device to perform a regular power supply operation. The first processing is processing for measuring a first voltage value while a power supply circuit of the target power supply device does not output an alternating current. The second processing is processing for measuring a second voltage value while the power supply circuit of the target power supply device outputs an alternating current. The adjustment system obtains a feeder circuit reactance of a feeder circuit based on the difference between the first voltage value and the second value, and executes adjustment processing for adjusting circuit characteristics with use of an adjustment unit in accordance with the obtained feeder circuit reactance in such a manner that the feeder circuit impedance is a predetermined impedance.
