The Battle Over Vanishing Spray

We talk a lot about patent disputes in today’s high-tech world. Whether it’s Wi-Fi, 3D printing, or progress bars, patent disputes can quickly become big money—for lawyers and litigants alike.

Where we see less of this, typically, is the world of sports. And yet, a recent football innovation has seen plenty of conflict in this very area. This is the controversial story of vanishing spray.

Patently Absurd

You might have played football (soccer) as a child, and if that’s the case, you probably don’t remember vanishing spray as a key part of the sport. Indeed, it’s a relatively modern innovation, which came into play in international matches from 2013. The spray allowed referees to mark a line with a sort of disappearing foam, which could then be used to enforce the 10-yard distance between opposing players and the ball during a free kick.

The product is a fairly simple aerosol—the cans contain water, butane, a surfactant, vegetable oil, and some other minor constituents. When the aerosol nozzle is pressed, the liquified butane expands into a gas, creating a foam with the water and surfactant content. This creates an obvious white line that then disappears in just a few minutes.

The spray was created by Brazilian inventor Heine Allemagne in 2000, and was originally given the name Spuni.  He filed a patent in 2000, which was then granted in 2002. It was being used in professional games by 2001, and quickly adopted in the mainstream Brazilian professional competition.

The future looked bright for Allemagne and his invention, with the Brazilian meeting with FIFA in 2012 to explore its use at the highest level of international football. In 2013, FIFA adopted the use of the vanishing spray for the Club World Cup. It appeared again in the 2014 World Cup, and many competitions since. By this time, it had been renamed “9.15 Fair Play,” referring to the metric equivalent of the 10-yard (9.15 meter) distance for free kicks.

The controversy came later. Allemagne would go on to publicly claim that the global sporting body had refused to pay him the agreed price for his patent. He would go on to tell the press he’d knocked back an initial offer of $500,000, with FIFA later agreeing to pay $40 million for the invention. Only, the organization never actually paid up, and started encouraging the manufacture of copycat products from other manufacturers. In 2017, the matter went to court, with a Brazilian ruling acknowledging Allemagne’s patent. It also ordered FIFA to stop using the spray, or else face the risk of fines. However, as is often the way, FIFA repeatedly attempted to appeal the decision, raising questions about the validity of Allemagne’s patent.

The case has languished in the legal system for years since. In 2020, one court found against Allemagne, stating he hadn’t proven that FIFA had infringed his products or that he had suffered any real damages. By 2022, that had been overturned on appeal to a higher court, which found that FIFA had to pay material damages for their use of vanishing spray, and for the loss of profits suffered by Allemagne. The latest development occurred earlier this year, with the Superior Court of Justice ruling that FIFA must compensate Allemagne for his invention. In May, CNN reported that he expected to receive $40 million as a result of the case, with all five ministers on the Superior Court ruling in his favor.

Ultimately, vanishing spray is yet another case of authorities implementing ever-greater control over the world of football. It’s also another sad case of an inventor having to fight to receive their due compensation for an innovative idea. What seems like an open-and-shut case nevertheless took years to untangle in the courts. It’s a shame, because what should be a simple and tidy addition to the world of football has become a mess of litigation that cost time, money, and a great deal of strife. It was ever thus.

Robotic Basketball Hoop V2

A few weeks ago, [Shane Wighton] created a basketball backboard which made it impossible to miss a shot even remotely close to the hoop. As a passive device, though, the backboard had its limits. Shots with tremendous velocity wouldn’t go in, and (like most backboards) it was missing facial recognition software. So he got to work on a second version which solves those issues, and takes a more active role in the game.

This version is flat, and looks largely unassuming until a game begins. The flat backboard is mechanized and includes a camera, so incoming shots can be analyzed in real-time while the backboard is moved into a position to direct the ball into the net. Or, since it does include facial recognition, the backboard can always send the ball away from the hoop, ensuring that [Shane] always wins basketball games no matter how many shots his opponent takes.

If you didn’t get a chance to see the original, we featured that a while back, and it’s truly a wonder when you learn about how much analysis went into creating the shape. The new version is even more impressive, doing all of that math in real time, and we can’t wait to see what [Shane] comes up with next.

Scorigami Bot Charts NFL History In The Making

NFL Football is a curious game to those who live beyond the borders of the continental United States. Its rules are many and complex, and its scoring system is built on arcane magic. This system means that there are many possible final game scores that have never actually happened in practice. For fans keen to hear of any first-time scores as they happen, Scorigami bot is here to help.

Charting and researching these is the practice of Scorigami, an idea first posited by Jon Bois, and is explored in this SB Nation video. It covers the many impossible scores in NFL, such as 1-0 and 1-1, as well as the possible-but-extremely-unlikely, like 6-1. To keep track of the state of Scorigami means following every score of every NFL game as its played. The ‘bot makes this easier; scraping the NFL livescores page with some nifty Javascript, it tracks each game live for potential first-time scores; the most recent as of writing being the Chiefs beating the Texans 51-31. Not only that, but the ‘bot estimates the most likely possible scorigami scores of games in progress, keeping fans on tenterhooks until the final whistle is blown. Or is it a siren in NFL? Inquiring minds need to know.

Code is naturally available on Github if you want to independently audit the Twitter feed; obviously the sanctity of scorigami results is absolutely paramount, and ensuring as such is a community responsibility. We’ve seen other live-score projects before, like this glowing Super Bowl football.

Hackaday Prize Entry: TooWheels, The Open Source Wheelchair

The Assistive Technology challenge of the Hackaday Prize received a large number of projects addressing many socially relevant problems. Mobility and transportation needs are a big challenge for those with limb disabilities. Not every country has proper, state-subsidised health care systems, and for many people in third world countries, devices such as wheel chairs are just not affordable. [Alessio Fabrizio] and his team developed TooWheels — an Open Source DIY wheelchair which can be customized and built using low-cost, local materials around the world and is one of the winners of the Assistive Technologies challenge round.

Originally conceived as a sport wheelchair, it has now evolved to answer different needs, due to feedback from the users and the community involved in the project. [Alessio] designed the project to be built from materials and resources easily available to any DIY maker at today’s Fab Labs and Makerspaces. The team have provided a detailed BOM to help procure all the required materials, instruction manual and drawings for assembly, and all the CAD files with customization instructions. Already, teams in Ecuador, India and Italy have replicated and built their own version of the TooWheel wheelchair. This confirms that the project is well documented and allows anyone around the world to download the plans and follow instructions to build their own wheelchair.

The wheelchair is built from CNC cut plywood sheets, aluminum pipes and bicycle parts and wheels. This makes it substantially cheaper compared to commercial wheelchairs, making it especially relevant for people in third world areas or where health care is not subsidised. The ease of customization allows fabrication of different wheelchair designs for sports, off-road or city use. The team is looking to bring this low-cost design to people around the world and are keen to collaborate with teams around the world to make it happen.
