ATLANTA, Ga. – Former President Jimmy Carter was released from Emory University Hospital in Atlanta on Wednesday morning after spending more than two weeks there following a 186

Boeing unveiled an overhaul Wednesday to a software system and the pilot training of its signature 737 MAX plane, marking its most direct attempt to fix an element of the plane's original design that investigators believe led to two recent crashes.At the company's plant in Renton, Washington, where the plane is assembled, Boeing pilots ran through scenarios on a flight simulator that was transmitted live into a conference room where regulators and some 200 pilots from client airlines were gathered, according to Mike Sinnett, Boeing's vice president for product strategy. The guests were able to request test simulations."We're working with customers and regulators around the world to restore faith in our industry and also to reaffirm our commitment to safety and to earning the trust of the flying public," Sinnett said. "The rigor and thoroughness in the design and testing that went into the MAX gives us complete confidence that the changes we're making will address any of these accidents."The gathering came at a 1038

B. Don Russell wasn’t thinking about preventing a wildfire when he developed a tool to detect power line problems before blackouts and bigger disasters.The electrical engineering professor at Texas A&M University figured he might save a life if his creation could prevent someone from being electrocuted by a downed live wire.But fire prevention may be his product’s biggest selling point in California and other places that have experienced devastating wildland blazes blamed on electrical equipment.“If we can find things when they start to fail, if we can find things that are in the process of degrading before a catastrophic event occurs, such as a downed line that might electrocute someone or a fire starting or even an outage for their customers, that’s kind of the Holy Grail,” Russell said.The technology he bills as a one-of-a kind diagnostic tool called Distribution Fault Anticipation is now in use in Texas and being tested in California by Pacific Gas & Electric Co. and Southern California Edison. The utilities have been blamed for some of the most destructive and deadliest fires in California.Texas A&M said the technology will also be tested in New Zealand and Australia, which is currently reeling from destructive wildfires.The tool detects variations in electrical currents caused by deteriorating conditions or equipment and notifies utility operators so they can send a crew to fix the problems, Russell said.It can anticipate many problems in their early stages — sometimes years before they cause an outage or present a greater hazard during high winds when utilities are now pre-emptively shutting off power to prevent sparking wildfires.Before the technology was developed, electric companies often didn’t know they had a problem until there was a failure or a customer called to report sparks on power lines or a loss of electricity.“The assumption the utility has to make today is it’s healthy until we get a call that says somebody’s lights (are) out,” Russell said. “By then the fire’s started or the outage has happened or the person’s electrocuted.”Pedernales Electric Cooperative Inc. that serves about 330,000 customers outside San Antonio and Austin, Texas, began implementing the system after successful tests that began in 2015. The utility serves areas so rural that before the technology was installed, electricity powering a pump on a well could have been off for days before being detected by a farmer.The devices installed at substations are now trouble-shooting all kinds of problems, said Robert Peterson, principal engineer for the utility.“We’ve found tree branches on the line. Failing arrestors. Failing capacitors. Failing connections,” Peterson said. “It’s pretty amazing.”In California, the testing process has just begun and there are no results yet, according to PG&E and SoCal Edison.In Southern California, the software is running on just 60 of Edison’s 1,100 circuits in the utility’s high-risk fire zone, which accounts for about a quarter of its total circuits.It’s just one of several tools the utility is testing to continue to modernize its system.“There is no silver bullet,” said Bill Chiu, managing director of grid modernization and resiliency at SoCal Edison. “This is really more of a preventive measure. ... The important point is this will be one of the suite of technology that will help us better assess the condition of the grid.”Chiu said the technology was not at the point where it could be used to determine where to shut off power when dangerous winds are forecast during dry conditions. He also said it won’t pinpoint problems but can help dispatch crews closer to the source of equipment that needs to be fixed, saving time that would be wasted patrolling miles of power lines.One question is whether the technology is economically feasible to deploy across tens of thousands of miles of power lines, Chiu said.At an expense estimated between ,000 to ,000 per circuit, it could cost the utility million in its high-risk fire area and that doesn’t include installation, operation and maintenance costs.That’s a fraction of what a moderate wildfire sparked by a utility could cost, Russell said.PG&E, which is testing the technology on nine circuits, was driven into bankruptcy protection this year while facing at least billion in losses from a series of deadly and destructive wildfires in 2017 and 2018.SoCal Edison recently agreed to pay 0 million to local governments to settle lawsuits over deadly wildfires sparked by its equipment during the last two years. That figure doesn’t include lawsuits by thousands who lost their homes in those fires or family members of 21 people killed when a mudslide tore down a fire-scarred mountain. Two other people were never found.Bluebonnet Electric Cooperative found the cost was feasible and has installed it on about a sixth of its circuits for the utility that has about 100,000 customers in Central Texas, said Eric Kocian, chief engineer and system operations officer.While the system has helped proactively diagnose problems and detect the cause of outages, the university team that developed it can often find problems the utility’s control room operators don’t detect.Pedernales Coop is working with an analytics company to streamline the analysis of the myriad information the software evaluates to find and fix problems in a day, Peterson said.Russell said he never had a hint the device his research team created 15 years ago would have fire prevention applications until a series of bad wildfires in Texas in 2011. They were focused on keeping power systems safe and the lights on.“It’s obvious now in today’s context of the drought that we’ve had in California and other places,” Russell said. “Serendipitously, that’s where we find ourselves today.” 5838

AURORA, Colo. – Twenty-four years after he was sentenced to life in prison without parole on a murder charge, a Colorado man has gotten a second chance at life and he’s making it count.Jeff Johnson, 41, was convicted in 1994 of killing John Leonardelli in a carjacking incident. But after the man who was convicted alongside him in Leonardelli’s death confessed and the U.S. Supreme Court changed its stance on juvenile sentences, Johnson was released from prison in November 2018. Johnson was 17 years old when he and Jonathan Jordan, then 19, were arrested for stabbing to death Leonardelli – a father of six – in an Aurora parking garage. Johnson said he saw Jordan stab Leonardelli but instead of helping the dying man, he instead jumped into Leonardelli’s Jaguar along with Jordan and left the scene.Both were convicted, but Jordan at one point admitted to killing Leonardelli. Johnson himself got into drugs while in prison but decided to turn his life around.Johnson started a program in prison to help other inmates and got involved in restorative justice programs to try and help mediate between criminals and their victims.“I came up with a motto for my life,” Johnson said. “A better life is a choice of way. I joined programs like Victim Impact, Victim Awareness, Restorative Justice. For me, that’s what gives my life purpose, and meaning. Being a mirror for them so they could see what you’re able to see.”Johnson met the woman who would change his life forever.“My name is Jenny Johnson, and I’m the wife of a juvenile lifer,” Jenny said. “I worked as a counselor, that’s how we crossed paths. They crossed for a reason. As for Jeff, it’s turning trauma into triumph, on all sides.”After Jordan confessed in a letter to Johnson, the U.S. Supreme Court ruled that automatic life sentences for juveniles were unconstitutional. Colorado passed a law eliminating juvenile life sentences, though they were not made retroactive.But the state looked at 48 cases involving prisoners who received such sentences as teenagers and, after hearing from one of Leonardelli’s sons and others, Johnson was resentenced on Oct. 23. And on Nov. 2, 2018, he walked out of the Fremont Correctional Facility a free man.Johnson ended up marrying Jenny, and the two of them gave birth to twins a few months ago. The couple stays in contact with Leonardelli’s family, who are close friends.“This is what they gave me,” Johnson said, holding a watch. “This is Leonardelli’s watch. I keep it and always remember what time it is, to make sure I’m living the best life I can live and make the best choices I can make.”“No words are going to express how bad I feel about everything happening. There’s absolutely nothing I can do to make it better or give back,” Johnson said. “I made several poor choices that night and I take full responsibility for those actions.”But now on the outside, Johnson is continuing the work he started in prison to try and prevent other teens from ending up in similar circumstances that he did.“When you’re involved with somebody losing their life, I feel like it’s my duty and gives my life purpose or meaning in life to come out here, take my story and help all these other kids,” he said. “We’re going to pick the best life we want over the choices that we make. The choices that we make define the character that we have.” 3354
