Technology is constantly evolving, and often times, it makes things more convenient.Charley Sullivan uses smart technology a lot, specifically her Amazon Echo.The Echo’s virtual assistant, Alexa, will read Charley’s emails aloud to her, check the weather and more.She thought it’d be a great gift for her husband, Bobby, but he knew she’d enjoy it more.“I knew how much she was going to use that thing,” he says. “I mean, she uses it to read her bible listened to radio programs; she plays games on it.” Amazon’s Alexa has brought convenience to homes everywhere, by playing music, checking the news, ordering groceries and more. But it’s especially helpful when you can't see.Both Charley and Bobby are blind.“Well, it's so wonderful,” Charley says of the device. “And when I was a child, we had braille, and we had books on records.”Now, the two are using Alexa, along cell phones and an Apple watch to make life easier.While they wish the technology could do even more, the two are grateful.“If you are going to be blind, this is the time, the day and time to be blind, with all the technology that there is out there today,” Charley says. 1155

TAMPA, Fla. -- As parents across the country grow more concerned every morning when they send their kids to school, more and more are turning to bulletproof backpacks.“After Sandy Hook, people couldn’t wrap their minds around a bulletproof backpack but now they think it’s something that they need," said Yasir Sheikh, the president of Guard Dog Security.The Sandy Hook shooting inspired Sheikh to create a backpack out of bulletproof materials. It doesn’t seem like much. The backpack has just a thin layer of kevlar, but it is certified to withstand handgun rounds.“Ideally, we think with the way things are going this should become mandatory, common for all students," said Skeikh. "It’s a sad reality, it’s become a new normal."Others feel the same. Just three days after the deadly school shooting in South Florida his company saw a 150 percent increase in the number of bags they shipped.But do they actually work?Ryan Hart is a certified firearm instructor for defense training company Ground Ready International Training, or G.R.I.T Ready. He also teaches active shooter survival courses.Hart put a barrel with sand behind the backpack to simulate a body and took aim with his Glock 19.“The rounds definitely penetrated the front of the bag here," said Hart inspecting the shot-up bag, "But if we flip it over there’s no penetration past the armor itself."Next up: the AR-15.In the last decade, this style of gun has been used in six of the 10 deadliest mass shootings throughout the country, including the Parkland school shooting.“It went right through the soft armor," Hart said after spraying the backpack with bullets from the AR-15.It's what Hart expected, as the Guard Dog Security backpack is not certified to withstand assault-style weapons. To stop bullets from a similar weapon, the backpack would need to be equipped with steel plates like those installed in military vests. However, that would make the backpack fairly heavy to carry.“I would recommend (the backpack), yes," Hart said. "While it did not stop a direct shot from an assault rifle it can still stop bullet fragments, ricochets, glass flying through the air.”Then we posed this question to Skeikh: "What do you think it says about our society that we are resorting to items like this?"The backpacks cost between 0-200. Fifty percent of the proceeds from sales of the backpacks right now will go to the victim's families of the Parkland shooting.Guard Dog Security is also looking into possibly making backpack, that would have the ability to stop assault-style weapons. 2664

Tesla on Thursday recalled about 123,000 Model S sedans, asking customers with cars built before April of 2016 to have their power steering bolts replaced.A Tesla spokesperson said the company has observed "excessive corrosion" of the part in some cold climates where a certain type of road salt is used.No injuries or accidents have been reported in connection with the issue, the spokesperson said.A Tesla spokesperson said that if the bolts fail, the driver should still be able to control the vehicle. The issue can make the car more difficult to steer at low speeds and to parallel park, and it should "not materially affect control at high speed."The company sent out emails to Model S owners who have cars included in the recall.The Model S has been lauded for its safety ratings, but news of this recall comes at a rough time for Tesla.Its stock price has plunged more than 25% over the past month. Investors are worried about the startup's ability to deliver on its first mass-market car, the Model 3, which has been plagued by manufacturing woes.Tesla's stock sank nearly 4% during after-hours trading Thursday after news broke about the Model S recall.The-CNN-Wire 1183

Statistics released by the U.S. Consumer Product Safety Commission on Friday claimed that 10,000 Americans were injured from firework mishaps in 2019, resulting in 12 fatalities.The agency says that 73% of the incidents occurred between June 21 and July 21. While seemingly more harmless than other fireworks, sparklers accounted for a plurality of the injuries, resulting in 900 injuries, half of those were from children under the age of 5.The CSPC said that fireworks killed at least 12 Americans in 2019, several of the deaths happened when victims held and ignited fireworks.With many local firework shows canceled or postponed this summer, there is concern over even more mishaps occurring this summer."Many Americans will not get to see the grand, professional fireworks displays this 4th of July given the cancellations of public celebrations and stay-at-home orders across the country. As an alternative, people are purchasing their own fireworks in an effort to recreate that tradition at home," said CPSC Commissioner Dana Baiocco. "The need for safety awareness regarding fireworks is greater than ever," she said, "and anyone who plans to use consumer fireworks this year should review and follow CPSC's simple safety tips to prevent injuries and incidents."The CSPC issued the following tips for a safe celebration:Never allow young children to play with, or ignite, fireworks, including sparklers. Sparklers burn at temperatures of about 2,000 degrees Fahrenheit—hot enough to melt some metals.Keep a bucket of water or a garden hose handy, in case of fire or other mishap.Light fireworks one at a time, then move away quickly.Never try to relight or handle malfunctioning fireworks. Soak them with water and throw them away.Never place any part of your body directly over a fireworks device when lighting the fuse. Move to a safe distance immediately after lighting fireworks.Never point or throw fireworks (including sparklers) at anyone.After fireworks complete their burning, douse the spent device with plenty of water from a bucket or hose before discarding the device to prevent a trash fire.Make sure fireworks are legal in your area, and only purchase fireworks that are labeled for consumer (not professional) use.For more fireworks safety tips, visit www.cpsc.gov/fireworks. 2308
