Evolution of Industrial Lasers: Persistence of Marshall Jones leads to revolutionary changes in additive manufacturing

The innovative work of Jones that led to his induction into the National Inventors Hall of Fame is on display in U.S. Patent No. 4676586, titled Apparatus and Method for Performing Laser Material Processing Through a Fiber Optic. Issued on June 30th, 1987, the patent protected an improved method of delivering laser energy to perform metal processing by generating a near infrared or visible wavelength pulsed laser beam, providing a single fiber optic with a quartz core having a diameter of less than 1,000 micrometers as well as cladding and protective shielding for the core end, focusing the laser beam onto the end of the core on a small spot with a diameter less than the core diameter at an including angle of less than 24°, coupling the beam into the fiber optic through air-core and core-cladding zones to transmit energy with a peak power in the kilowatt range, and then focusing the laser beam emerging from the fiber optic onto a workpiece at a power density sufficient for metal processing. The invention resulted in a laser beam delivery system with minimal optical losses and improved freedom of laser beam manipulation capable of being robotically controlled.

Tech Round-Up: Anonymous Takes on ISIL, Square IPO Beats Estimates and a Freeze Ray

From tech developers trying to take a stand against tech-savvy terrorists to a pair of highly anticipated initial public offerings of stock for tech start-ups, there’s been plenty of news to cover in recent days. We also take a little time to explore research at an American university which has led to the world’s first-ever “freeze ray” laser technology.

How Thanksgiving Leftovers Lead to the Invention of LASIK

Sitting at the dinner table with his family on Thanksgiving in 1981, Srinivasan looked at his turkey dinner and a brilliant thought occurred to him: a leftover bone with cartilage would provide the perfect test subject. The cartilage and other tissues attached to the turkey bone could approximate the physical structure of human tissue, and the smoothness and rigidity of the cartilage would make it easier to read the results of the experiment. On November 27, 1981, the team operated an argon fluoride (ArF) excimer laser to create a clean etching on the turkey’s cartilage that could be viewed when placed under an optical microscope. Further tests on the cartilage helped the team understand how many laser pulses were required to make a cut, the amount of energy delivered via the laser beam and the impacts of the laser on adjacent tissues.

Intel Innovation: Live Music Performance, Pool Cleaners, Adaptive Facial Recognition System, Offline Advertising

Live music performance broadcast across Internet channels is the focus of today’s featured patent application here at IPWatchdog. Intel is hoping to protect a system that builds off of previous systems of networked music performances to better incorporate audience reactions and build a more inclusive entertainment experience. We’ve also picked up on a couple of user recognition systems, one for improving gesture-based user interfaces and another that enhances facial recognition software for computer security by registering genuine human facial reactions. Today’s issued patents protect some novel innovations related to the way a computer system can interact with an individual, instead of the other way around. One patent protects a system that can provide advertising content to device users who are offline, while another protects a second facial recognition for computer security technology, this one capable of identifying unknown faces by accessing an image database. We also have some interesting Internet TV technologies that are assigned to Intel today, but may quickly be moving to Verizon.

Invention to Patent: The Pitfalls, Perils and Process

There are a number of things that you need to know about the invention and patent process that can help you focus your efforts and know what obstacles lay in front of you. Once you conceive (idea + game plan) you will need to be diligent and not let any grass grow under your feet as you move forward toward defining and experimenting with your invention. Generally speaking, conception without diligence can cause the first person who invents to lose the right to the invention assuming someone else invents after you but files their patent application first. So, the moral of the story is once you have your idea and the game plan move swiftly. The law realizes that so-called “garage inventors” cannot quit their day job, but the law will also require proof that you are consistently moving forward and not shelving the invention for periods of time in favor of other endeavors.
