Title: J James Stone: Innovator in Thermal Verification and Laser Marking Technologies
Introduction
J James Stone is a notable inventor based in Northbrook, Illinois, recognized for his contributions to thermal verification and laser marking technologies. With a total of four patents to his name, Stone has made significant advancements in the field of printing and imaging.
Latest Patents
One of his latest patents is a system and method of thermally verifying freshly printed images. This innovative system detects a latent image formed with invisible ink by utilizing a mechanism, such as a heater, to create a temperature differential between the ink and the substrate. An ink delivery system, like an ink jet printer, applies the ink to the substrate, forming a latent image. A heat-sensitive scanning device then scans the substrate, outputting an electrical signal that corresponds to the temperature differential before thermal equilibrium is reached. This signal contains information representative of the image, which can be displayed, recorded, or processed to verify the printed image.
Another significant patent is the laser marker system, designed for marking indicia onto a substrate. This system includes an exit lens with a specific focal length and a single laser source. The substrate is positioned at the focal plane of the lens, and the laser source's energy output beams are oriented in a parallel relationship. The system features segmented reflecting means that generate multiple output energy beams, creating a column of spots on the substrate with higher resolution. A device is included to move the mirror segments between lasing and non-lasing positions, allowing for variation in the number of output energy beams and spots.
