Experts praise the black dots on automobile windshields as a technical marvel that are crucial to overall performance while being frequently ignored. These dots are a component of the frit band, a textured enamel paint strip that surrounds the edge of the windshield. This band is essential for improving the grip of the adhesive and glass, which guarantees the windshield is securely attached to the vehicle.
In addition to serving as structural elements, the black dots cover the glue from UV rays that could be harmful. This protection stops extended sun exposure from degrading the adhesive bond over time.
The dot matrix, which is made up of ever smaller dots, helps to ensure that the temperature is distributed evenly across the windshield during the production process. By taking this proactive step, optical distortion or “lensing” is avoided, guaranteeing that straight lines on the glass stay true.
The slow fading of the black dot matrix is responsible for the visually pleasant transition from the transparent glass to the black frit border. Furthermore, by strengthening the windshield’s structural integrity, this design decision reduces the likelihood of damage.
Essentially, those seemingly insignificant black spots on your windshield have a multitude of functions and are essential to the complex machinery of your car.
Mom of rare twins with Down syndrome shuts down critics with photo showing how beautiful they are
While the chances of giving birth to twins increased 72 percent between 1980 and 2018, it’s still pretty rare. About 33 out of every 1,000 births are twins.
And what are the chances of identical twins? Approximately every three or four births out of every 1,000 are identical twins. So again, relatively rare.
When 23-year-old Savannah Combs found out she was pregnant with twins, she was thrilled. And then she learned another rarity, they both had Down syndrome.
Of course, it was emotional news. Savannah and her husband, Justin Ackerman, knew that some people would judge her and her babies because of their condition.
But to Savannah, that’s what makes them incredibly precious.
“It’s very rare what they have, but they’ve been my little gems,” she told News4JAX.
Savannah, who is from Middleburg, Florida, shared her post-pregnancy journey with her daughters Kennadi Rue and Mckenli Ackerman, on TikTok where they quickly gained a following.
In one of her videos, Savannah said she was told to abort her babies because they would not make it.
She decided to keep them and give them a fighting chance.
”Every [prenatal] appointment they were alive was a blessing to me,” Savannah explained.
When she learned they both had Down syndrome, her husband was away at boot camp.
Savannah was 29 weeks pregnant when she was admitted to the hospital, and delivered her daughters. The identical twin girls, Kennadi Rue and Mckenli Ackerman, were born on May 12, 2021.
The twins arrived two months before their due date, so they had to spend several weeks in the NICU before they came home.
They’re called mono di twins, meaning that they had their own sacs, but they shared the same placenta, meaning that they were going to be identical,” she said.
“Mo di twins as it is, it’s like very rare. And then you throw Down syndrome on top of it, it’s like one in 2 million.”
Despite their rare condition, Savannah said they are just like any other child.
“They have feelings. They have a beating heart. They know how to talk. They know how to do things you do. They will get there,” she said.
“Like I said, it may be a step behind but they’re going to do it. I’ve learned these kids are feisty little things and happy little things.”
