SAN DIEGO (KGTV) - Imagine having the power to change your body’s temperature at any time, regardless of how hot or cold it actually is. UC San Diego engineers are on they’re way to doing just that, with a wearable patch.Like a thermostat, it can be changed to a specific temperature, warming or cooling the body, using far less energy than an air conditioning system. “Cooling is a really important issue faced by society today. If you look at news reports there are extreme weather conditions, for example in India, peak temperature could be over 50 degrees Celsius in July," said Renkun Chen, a Professor of Mechanical and Aerospace Engineering at UC San Diego.The patch is made up of thermoelectric alloys - materials that use electricity to create a temperature difference and vice versa - sandwiched between stretchy elastomer sheets. The device physically cools or heats the skin to a temperature that the wearer chooses. The patch is powered by a flexible battery pack. It is made of an array of coin cells all connected by spring-shaped copper wires and embedded in a stretchable material. The system also includes a stretchable circuit board.By regulating the temperature around an individual person, rather than a large room, the smart fabric could potentially cut the energy use of buildings and homes by at least 15 percent.The technology could also be used for people who work in extreme environments, like firefighters or miners. Eventually, Chen and his team want to integrate the technology into clothing. They hope to sell it commercially in the next few years, along with developing a mobile app to control the temperature. The research was funded with a .6 million grant from the U.S. Department of Energy. 1736

SAN DIEGO (KGTV) -- Leonardo Hurtado Ibarra is being remembered as a family man with a complex and troubled life.“He’d always keep a smile on his face regardless of whatever he was going through," Abril Huerta told ABC 10News.Ibarra, 25, was shot and killed after allegedly pointing a revolver at a San Diego Police Department officer in Downtown San Diego on Saturday night.According to police, officers recognized Ibarra from a wanted poster in connection with a robbery that happened last week. Police said officers tried to talk with Ibarra but he walked away.Ibarra then dropped some items from his arms and "reached into his waistband," according to police. That's when officers, fearing for their lives, opened fire, police said.RELATED: SDPD release surveillance video, body cam footage from officer-involved shooting in Downtown San DiegoABC 10News asked Huerta if Ibarra was known to carry a weapon. She said Ibarra "wasn’t a saint" and that he had a "complicated background."Ibarra was sentenced to three years in prison stemming from a domestic abuse case in 2013, according to court records obtained by ABC 10News.Huerta, who said she was the love of Ibarra’s life, told ABC 10News that he leaves behind three children.“He loved his family," Huerta told 10News in a statement. "He was the most loyal individual you could ever meet and he’d give you the shirt off his back if you were in need."“He only wanted to defend himself from any harm that were to come his way,” she said. The police department has not released the names of the officers involved in the shooting. The case will be reviewed by the county District Attorney's Office to determine if the officers are subject to any criminal liability, according to police.San Diego Police could not comment further while the investigation is ongoing. 1824

SAN DIEGO (KGTV) - Last month, investigators arrested a 72-year-old man suspected of being the Golden State Killer. It could be the dramatic end of a four decades old search for the suspect.Which got us thinking, whatever happened to the cold case of the “Geezer Bandit” who may not even be a senior citizen anyway? And, could advanced technology ever help find him?He was the most elusive senior citizen during a two-year crime spree. The bank robber the FBI nicknamed the “Geezer Bandit” because of his geriatric appearance.The “Geezer”, who may have been a much younger person using a professional grade prosthetic mask, robbed 16 banks from San Diego to San Luis Obispo from 2009 to 2011. 11 of those robberies happened in San Diego County. “Profiling as you understand now is a pretty big spectrum,” says Jack Hamlin.Hamlin is a Professor at National University and professional criminal profiler. We asked him how this person, seven years later, has become the modern-day D.B. Cooper and why he, or she, would simply vanish.“We have an expression in law enforcement, we only catch the dumb ones,” says Hamlin.The “Geezer” was one of the best. Performing almost mistake free and seemingly very sophisticated. The mask may not have been his only disguise, and he was said to wear gloves, there was no known getaway vehicle, the robberies were during off-peak hours and with little security. And five of his robberies were on a Friday, payday. So, we asked the question, ‘Is it possible this person had some law enforcement training?’“It’s certainly somebody that understands how things work,” added Hamlin.  “These robberies weren’t random. He’s figured out a time when security is low; he’s figured out a time when there’s going to be plenty of cash, Friday.”The “Geezer developed a cult following with thousands of followers on Facebook. T-shirts are still available celebrating ‘Geezer Bandit for President.’ But his last robbery was December of 2011. That's the only time a dye pack was used, exploding and making the money useless, and possibly his disguise too. We haven’t heard from the “Geezer” since.“I don’t see this person suddenly having an epiphany and saying, ‘It’s over with. I don’t need to do it anymore,’” says a skeptical Hamlin.Hamlin says people like this need the rush and rarely just quit. But the one mistake the “Geezer” made on that final robbery was dropping a day-planner which he carried as part of his disguise. If it holds his DNA, Hamlin says there may be an option to use a genealogy website like investigators did to catch the person they believe is the Golden State Killer.“Now you’ve got this public DNA base, and if there is some way they can tap into that, um, the skies the limit on some of these cases,” says Hamlin.UPDATE: The FBI tells 10News there has been no change in this case since the last attempted robbery in 2011. However, the field office in San Diego is always willing to work with the community if there is new information that might lead to an arrest of the person known as the "Geezer Bandit."

SAN DIEGO (KGTV) -- Looking around Barrio Logan, you can't miss the shopping carts, tents and camps belonging to the homeless. Residents of the San Diego neighborhood say the city is turning their community into a "homeless ghetto" - and it's time for it to stop. Tuesday night a group gathered outside the Our Lady of Guadalupe Church, calling on the city to provide "fair distribution of homeless services across San Diego.""It's unbelievable what the mayor and the City Council are doing to this area," said Father John Auther. The priest pointed to a map, asking why a nearly 370 square mile city is putting most of the homeless services in a one-quarter square mile. Father Auther says the concentration of services goes beyond the residents of Barrio Logan. It's bad for the homeless community, too. The area was hit hard by the hepatitis A outbreak.RELATED: Health officials reminding San Diegans about hepatitis A shot "Many of the homeless as we know suffer from addiction problems, alcoholism, mental illness, and what the city has decided to do is put all of them together," Father Auther said. "How will anyone get well?"Right now, city crews are working on a transitional homeless facility in the neighborhood. The facility is going up just 15 feet away from a school playground. A playground closed because of the homeless issue. "We can no longer feel comfortable, feel safe with our students down here on this playground," said Noel Bishop, principal of Our Lady's School San Diego.10News asked a few people in the homeless community two questions: 1. Will the new facility help you? All said yes. 1651
