These LED Crosswalks Adapt to Whoever Is Crossing

Crosswalks are an often-neglected part of urban design; they’re usually just white stripes on dark asphalt. But recently, they’re getting more exciting—and safer—makeovers. In the Netherlands, there is a glow-in-the-dark crosswalk. In western India, there is a 3D crosswalk. And now, in London, there’s an interactive LED crosswalk that changes its configuration based on the situation, as Fast Company reports.

Created by the London-based design studio Umbrellium, the Starling Crossing (short for the much more tongue-twisting STigmergic Adaptive Responsive LearnING Crossing) changes its layout, size, configuration, and other design factors based on who’s waiting to cross and where they’re going.

“The Starling Crossing is a pedestrian crossing, built on today’s technology, that puts people first, enabling them to cross safely the way they want to cross, rather than one that tells them they can only cross in one place or a fixed way,” the company writes. That means that the system—which relies on cameras and artificial intelligence to monitor both pedestrian and vehicle traffic—adapts based on road conditions and where it thinks a pedestrian is going to go.

If a bike is coming down the street, for example, it will project a place for the cyclist to wait for the light in the crosswalk. If the person is veering left like they’re going to cross diagonally, it will move the light-up crosswalk that way. During rush hour, when there are more pedestrians trying to get across the street, it will widen to accommodate them. It can also detect wet or dark conditions, making the crosswalk path wider to give pedestrians more of a buffer zone. Though the neural network can calculate people’s trajectories and velocity, it can also trigger a pattern of warning lights to alert people that they’re about to walk right into an oncoming bike or other unexpected hazard.

All this is to say that the system adapts to the reality of the road and traffic patterns, rather than forcing pedestrians to stay within the confines of a crosswalk system that was designed for car traffic.

The prototype is currently installed on a TV studio set in London, not a real road, and it still has plenty of safety testing to go through before it will appear on a road near you. But hopefully this is the kind of road infrastructure we’ll soon be able to see out in the real world.

The ChopBox Smart Cutting Board Has a Food Scale, Timer, and Knife Sharper Built Right Into It

When it comes to furnishing your kitchen with all of the appliances necessary to cook night in and night out, you’ll probably find yourself running out of counter space in a hurry. The ChopBox, which is available on Indiegogo and dubs itself “The World’s First Smart Cutting Board,” looks to fix that by cramming a bunch of kitchen necessities right into one cutting board.

In addition to giving you a knife-resistant bamboo surface to slice and dice on, the ChopBox features a built-in digital scale that weighs up to 6.6 pounds of food, a nine-hour kitchen timer, and two knife sharpeners. It also sports a groove on its surface to catch any liquid runoff that may be produced by the food and has a second pull-out cutting board that doubles as a serving tray.

There’s a 254nm UVC light featured on the board, which the company says “is guaranteed to kill 99.99% of germs and bacteria" after a minute of exposure. If you’re more of a traditionalist when it comes to cleanliness, the ChopBox is completely waterproof (but not dishwasher-safe) so you can wash and scrub to your heart’s content without worry. 

According to the company, a single one-hour charge will give you 30 days of battery life, and can be recharged through a Micro USB port.

The ChopBox reached its $10,000 crowdfunding goal just 10 minutes after launching its campaign, but you can still contribute at different tiers. Once it’s officially released, the ChopBox will retail for $200, but you can get one for $100 if you pledge now. You can purchase the ChopBox on Indiegogo here.

Mental Floss has affiliate relationships with certain retailers and may receive a small percentage of any sale. But we choose all products independently and only get commission on items you buy and don't return, so we're only happy if you're happy. Thanks for helping us pay the bills!

Remembering Sara Little Turnbull, Whose Bra Cup Design Became the N95 Mask

The coronavirus pandemic has made something of a celebrity out of the N95 mask, a particle-filtering face covering that’s long been used to protect wearers from inhaling or exhaling pathogens. (The “95” refers to the fact it can block 95 percent of airborne particles.)

Like most nondescript and pervasive products, not many people stop to think about where it came from. Now, owing to the attention placed on it as a key tool in the health care professional’s fight against coronavirus, the woman behind the mask has come to the forefront. Her name is Sara Little Turnbull, and she designed what would become the N95 based on the shape of a bra cup.

A design consultant, Turnbull was working with the 3M company in 1958 in their gift wrap and fabric division when she was exposed to Shapeen, a non-woven material made of polymers and used for decorative ribbons. Turnbull was fascinated by the molded version of Shapeen and devised the first-ever pre-made bows for gift wrap.

Turnbull didn’t stop there. She saw endless possibilities in Shapeen and assembled an audience of 3M executives to present a number of ideas she had for products—more than 100 in all—using the material. At the presentation, which she titled “Why,” she impressed 3M with the scope of Shapeen's potential. The company quickly enlisted her to work on a design for a molded bra cup.

But Turnbull had another, arguably more important notion. At the time, she was taking care of three ailing family members who were under the care of doctors. Turnbull was often in a medical setting and noticed health care workers were constantly adjusting thin masks that tied in the back. She returned to 3M with the idea of using that same molded material to make a mask that would fit more comfortably on the face.

Again, 3M saw potential in Turnbull’s idea. By 1961, they introduced a non-woven lightweight medical mask based on her concept, with elastic bands instead of strings, an aluminum nose clip, and a form-fitting "bubble" shape. (The bra patent was approved in 1962.) Though innovative, the mask couldn't block pathogens for medical use and was marketed for dust filtration instead. An improved respirator hit the market in 1972 that was suitable for other industrial purposes. As the mask’s filtration evolved, so did its usefulness. In 1995, the N95 respirator was introduced in the health care field, fulfilling Turnbull's original ambition.

Though Turnbull had been relegated to a nondescript part of 3M, she had an extensive background in design, graduating from the Parsons School of Design in 1939 and later becoming the decorating editor of House Beautiful magazine. After Turnbull wrote an article taking companies to task for not designing products suitable for the end user, she was hired by 3M. As a consultant, she also collaborated with Corning, Revlon, General Mills, and Ford, among others.

After Turnbull died in 2015, the Sara Little Turnbull Center for Design Institute was formed, which offers information to the public on the value of design and supports the efforts of disadvantaged women's design education. Turnbull's vast archive of material is available to view by appointment. A foundation in her name also provides educational grants. The “Little,” incidentally, was in acknowledgment of her height. At 4 feet, 11 inches tall, Turnbull wasn’t terribly physically imposing. But her contributions were gigantic.
