  • Patent number: 11232942
    Abstract: A method for treating a substrate is provided. The method includes supplying a first treating liquid to a treating target surface of the substrate while the substrate is rotating, and subsequently, supplying a second treating liquid having a surface tension lower than a surface tension of the first treating liquid to the substrate while an evaporation inhibiting agent in a vapor state is present around the first treating liquid supplied to the substrate, such that the first treating liquid on the substrate is substituted with the second treating liquid. Thus, a vapor atmosphere may be formed around a cleaning liquid applied to the substrate. Thus, a liquid-film destroying phenomenon may be prevented in a procedure in which the cleaning liquid is replaced with an organic solvent.

  • Patent number: 11173880
    Abstract: A vehicle washing system and a method for operating such a vehicle washing system in which a vehicle is scanned in a longitudinal direction by a sensor device. Measurement data are captured so that position data for the positions of vehicle wheels are determined based on an evaluation of the measurement data. The determined position data of the positions of the wheels are subjected to a confidence check, so that a confidence measure is determined. If the determined confidence measure is greater than or equal to a confidence threshold value, a treatment of the wheels is carried out in a first mode at the positions associated with the position data, and, if the determined confidence measure is smaller than the confidence threshold value, a treatment of the wheels is not carried out, or is carried out in a second mode at the positions associated with the position data.
