Latest Patents
One of Hunter's latest patents is titled "Laser machining of a workpiece through adjacent mask by optical elements." This invention involves a laser machining system that utilizes a perforated proximity mask placed on or near a generally planar workpiece surface. The holes in the mask define a pattern of holes or marks on the workpiece, which are formed by laser beam pulses passing through the mask. The system employs rotatable mirrors to direct the laser beam to various holes in the mask, ensuring precision in the machining process. The optical elements used in this system convert the beams into parallel beams that strike the workpiece surface normally, while also focusing each beam effectively.
Another significant patent by Hunter is the "Character imaging system." This system allows for the optical projection of selected characters onto a working surface without the need to move the mask or the working surface. The system can burn impressions into a workpiece, spelling out words and sentences using laser light. The innovation lies in the ability to sequentially select different characters in the mask while maintaining the desired location of the projected beam on the workpiece.
