Patent ID: 7692174

Claim:
A method comprising: providing a substrate with a preformatted structure, with structural elements arranged in a matrix, wherein the matrix extends in an X-direction and a Y-direction, the structural elements having boundaries, providing a processing head, providing a camera that is connected with the processing head and that comprises at least one series of sensors arranged along a main line, using the camera to scan the substrate, thereby providing at least one one-dimensional camera signal, wherein, for real-time determination of at least the X-position and the Y-position of the structure with respect to the camera, said main line includes an angle with the X-direction and with the Y-direction, wherein the angle is chosen such that the camera signal comprises X-position information and Y-position information regarding the structural element boundaries, and determining the X-position and the Y-position of the preformatted structure relative to the camera through signal processing of the camera signal.
