Disclosed are a method and/or a system for real-time analysis and marking of a target surface using a digital camera coupled marking device. In one embodiment, a master controller receives a real-time digital camera signal from the digital camera of a marking device communicatively coupled to the master controller. The master controller analyzes the digital camera signal using an image recognition algorithm, a machine vision algorithm, and a database and archives a visual state and an object design parameter of an object. The master controller compares the visual state of an object with a library of known visual states in the database to extract an associated marking pattern and a desired marking location of the object. The master controller generates and sends a marking command to a pin marker of the marking device. The pin marker engraves the marking pattern onto the object in real time.

Method and system of real-time analysis and marking of a target surface using a digital camera coupled marking device

Disclosed are methods, systems, and/or apparatus for the collective marking of a surface by two or more laser beams generated by a laser controller. A method includes receiving one or more input signals from a controller of the laser system. The method also includes adjusting a first mirror through a first galvanometer scanner, a second minor through a second galvanometer scanner, a third mirror through a third galvanometer scanner, and a fourth mirror through a fourth galvanometer scanner based on the one or more input signals. The method further includes steering, through the first mirror and the second mirror, a first laser beam generated by the controller and transmitted to a marking head through a beam delivery vessel; and steering, through the third mirror and the fourth minor, a second laser beam generated by the controller and transmitted to the marking head through another beam delivery vessel.

Collective marking of a surface by steering multiple laser beams generated by a laser controller

A method, an apparatus and/or a system of laser marking of an interior cavity of a securing means of a substance container is disclosed. In one embodiment, a solid-state laser marking system to mark a securing means of a substance container includes a semiconductor laser to emit a pumping laser beam. The solid-state laser marking system also includes a resonator to create the laser beam that is then focused through a lens to mark the securing means of the substance container having a maximum diameter of 5 cm. Further, the solid-state laser marking system includes a solid-state laser crystal doped with a rare-earth element, to produce a laser beam in response to being pumped by the pumping laser beam and a laser resonator. The laser resonator is configured to focus the laser beam of a spot size of less than 150 microns and a beam quality of Mless than 1.3.

A laser safety system providing a system for checking the presence, focus and integrity of a laser beam focusing lens is disclosed. The laser safety system checks the focusing lens properties by capturing an image of a target by viewing the target through the focusing lens from along the laser beam path. An initial, known good, image is compared to an image captured immediately before enablement of the laser beam source to determine if the focusing lens is present, focused and is not damaged. The system may also utilize a mask projected onto the target as well as a low-power visible light laser directed along the path of the processing laser to determine the focusing lens properties. The system can also provide target recognition.

Laser safety system

A flexible laser safety curtain is disclosed that utilizes a plurality of columns flexibly attached to one another along their longitudinal edges in such a manner as to create a curtain of columns. The base of each column contains a cavity within which at least one moveable element, columnar in form, may be located and protrude from the cavity. The moveable element, when pressed against a work surface, is forced into the cavity. A biasing element within the cavity provides an opposite force on the moveable elements to both keep the moveable element in contact with the work surface, and to return the moveable element to its original position when the inward force is removed. The curtain's edge follows the contours of an uneven work surface and thereby the curtain provides a complete barrier to laser radiation.
