  • Patent number: 7397014
    Abstract: The present invention relates to an apparatus and a method for marking an object, particularly a vehicle, by disrupting the material of the interior or surface of the object. The system comprises a laser emitter (102), a laser beam delivery means (104) which can be flexible, and a marking heading (105) which is light enough to be carried by an operator.

  • Patent number: 6815637
    Abstract: The present invention provides a method and apparatus for marking vehicles using a laser. In order to allow any part of the vehicle to be marked using a simple, strong laser beam delivery conduit, the laser is mounted on a structure 101 which extends over a vehicle station 102. The structure defines at least three laser mounting positions and preferably four laser mounting positions A, B, C, D, spaced apart from one another in two dimensions for mounting at least one laser apparatus 107. The laser apparatus 107 comprises a laser emitter 108 for producing a laser beam adapted to mark a part of the vehicle and laser beam delivery means 110 for delivering a laser beam from the laser emitter 108 to a selectable point of the vehicle station 102. The laser apparatus 107 is movable between at least two and preferably all four of the laser mounting positions A, B, C, and D.
