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.

Abstract: A disclosed tool coupling may include a clamp configured to hold a stirring tool and a shank connected to the clamp, the shank and the clamp sharing an axis of rotation, the clamp including a clamp housing defining an open interior region configured to receive the stirring tool and at least one adjustable fastener operably connected to the clamp housing, the fastener being configured to retain the stirring tool within the interior region.
