  • Patent number: 11933606
    Abstract: A vehicle wheel alignment system has a plurality of cameras, each camera for viewing a respective target disposed at a respective wheel of the vehicle and capturing image data of the target as the wheel and target are continuously rotated a number of degrees of rotation without a pause. The image data is used to calculate a minimum number of poses of the target of at least one pose for every five degrees of rotation as the wheel and target are continuously rotated the number of degrees of rotation without a pause. At least one of the cameras comprises a data processor for performing the steps of preprocessing the image data, and calculating an alignment parameter for the vehicle based on the preprocessed image data.

  • Publication number: 20230008997
    Abstract: A system and method for reducing a vapor temperature in a packed distillation column. Liquid is collected from a packed section of the packed distillation column in a liquid collector disposed below the packed section. A super-heated vapor is distributed from a vapor feed disposed below the packed section such that the super-heated vapor contacts the liquid of the liquid collector and reduces a temperature of the super-heated vapor.
