Patent 7804604 was granted and assigned to Boston Scientific on September, 2010 by the United States Patent and Trademark Office.
A system measures a location of a drop delivered by, for example, an ink-jet type applicator. An image of the drop is captured from two directions, resulting in two drop images. Only one image capturing apparatus is needed to capture the drop images. The location in three-dimensional space is determined by using the two images but only one image capturing device. The position or location information can then be used to calibrate a coating apparatus.
