LAS VEGAS, Nevada — More changes could be coming to the "free drink" system in Las Vegas casinos.There is special technology on table-top machines, such as video poker, that monitors when you earn a comped drink. Now, gamblers may see it on slot machines, too.Ardent Progressive Systems and Games has already installed its technology on about 90 slot machines at The Riverside Resort in Laughlin.It's considered a trial run for a couple months to see how it goes."The hope now is, the trial down in Laughlin will be successful and then we've got several properties that are waiting to see the results of that and possibly implementing it in the near future up here in Las Vegas," said Albert Tabola with Ardent Progressive Systems and Games.The technology is a strip of LED lights that faces you while you play. Red means you're not ready for a drink. Green means you are ready for a drink. Yellow means you're getting close to qualifying for a drink. Orange means you're playing too slowly and falling off track."You will know as you play whether you qualify for a complimentary drink or not, as will the cocktail waitress," Tabola said.Players do not have to play max bet to qualify for a drink. They ust need to consistently play."The qualification levels on there are very, very low so this should not affect anybody that plays for the most part, at all," he said. "Ideally, the only person that will be grumbling about this will be the person that wants to get that free drink before they go into a show by just sitting down at the machine and maybe playing a penny or wherever they can get away with."Casinos in Las Vegas will be keeping an eye on the trial run in Laughlin right now before making a decision as to whether they should implement it on slot machines here in the city. 1811

LAKESIDE, Calif. (KGTV) - A woman in Lakeside has set up a cabinet full of "Goodies to Share" for homeless people living near Cactus Park.Barbara DeYoung says she got the idea from the "Little Free Libraries" she sees in her neighbors' yards."You just go very freely and get something. It's just people sharing with you," she says. "It's a very nice feeling, and I thought for sure they would love that."She set up the cabinet near the San Vincente Creek that runs behind Cactus Park, an area where several homeless people have set up encampments."I felt these are wonderful human beings. But they have problems. They have situations they can't control," DeYoung explains. "But they can read a book in the evening. They can play games, whatever they need to do."Rather than filling the cabinet with food, DeYoung stocks it with comfort items like books, blankets, wipes, playing cards, and other things that aren't usually available to homeless people at shelters or service offices.DeYoung says it's about feeding their souls and showing them respect and love, rather than just handing them food.The cabinet has already become a hit. DeYoung had to restock it just a few days after she first set it up. And just a few minutes after she refilled the cabinet, our cameras caught a man coming up from the creek bed to grab some wipes out of it.He asked not to be identified but says it feels good to know that people care.Meanwhile, DeYoung doesn't believe it will attract more homeless people to the area, but it will make life more bearable for the ones already there."I don't think boxes of raisins are going to bring armies of people here," she says. "But the people that are here, I think they could have a little respect from us. A little love, a little care." 1772

LA JOLLA, Calif. (KGTV) - Researchers at UC San Diego have found a way to improve radar technology that can make self-driving cars safer."Our vision is to make self-driving cars much more safer than how we humans drive," says Dinesh Bharadia, an Assistant Professor of Electrical and Computer Engineering at UC San Diego.Bharadia led a team of researchers working on ways to help autonomous vehicles see in bad weather.Currently, he says, self-driving cars rely on LiDAR, a light-based radar system. But it's performance is limited because it uses a low frequency that reflects in bad weather.Bharadia says his team tested wireless radar, which has a higher frequency wavelength and found it can rain and fog.However, the wireless radar's sight range is limited. So Bharadia's team built a system where five wireless radars work together to create a more full "view" of the road."From each radar's vantage point, you see something different," says Bharadia. "Those different things, observed from five different radars, gives you much more detailed aspect ratio of another car (on the road)."Bharadia says the combination of all five radars helps create a 3-D image of other objects on the road. That helps the car's self-driving system figure out how to avoid them."You need to know the exact aspect ratio of the other cars on the road," he says. "Only then can you drive around them if you need to."Bharadia says carmakers like Toyota and Honda have been helping with the research and development. He thinks this new technology could be on the road within 2-3 years."Radars are already out there," he says. "We just need to plug in our software to make the cars more autonomous..."It's a simple technology that can be widely deployed and used to make our roads safer for everyone."Bharadia and his team will present their findings at the Sensys Conference this week. For more information about the technology, see the full news release here. 1951
