    Days After A Fiery Crash, a Tesla's Battery Keeps Reigniting
    An anonymous reader quotes the Mercury News Six days after a fiery crash on Highway 101 involving a Tesla Model X took the life of a 38-year-old San Mateo man, the car's high-voltage lithium-ion battery re-ignited while sitting in a tow yard, according to the Mountain View Fire Department... The battery reignited twice in the storage yard within a day of the accident and again six days later on March 29. Two weeks later, in an effort to avoid more fires, the NTSB and Tesla performed a battery draw down to fully de-energize it... On the company website, Tesla wrote "the reason this crash was so severe is that the crash attenuator, a highway safety barrier which is designed to reduce the impact into a concrete lane divider, had either been removed or crushed in a prior accident without being replaced. We have never seen this level of damage to a Model X in any other crash"... Tesla also reported that the vehicle's autopilot function was active at the time of the crash... The National Transportation Safety Board is investigating the Highway 101 crash and three other accidents also involving Teslas, including a fiery 2014 Model S crash Tuesday in Florida that killed two teenagers. Also under investigation: A Model S crashed into a fire truck near Culver City in January, and the driver reportedly said Autopilot was engaged at the time. And it is looking into a battery fire of a Model X that drove into a home's garage in Lake Forest in August. Two hours after that story was published, a Tesla smashed into a Starbucks in Los Gatos, California.

    'Father of GPS' Receives the IEEE Medal of Honor
    "A former paperboy from Wisconsin passionate about maps led the team in the Air Force responsible for designing the navigation system we use everyday," writes Slashdot reader dkatana. IoT Times reports: At the IEEE honors ceremony today in San Francisco, Bradford Parkinson, a retired Air Force colonel who spent his life between maps and navigation systems, will be awarded the 2018 IEEE Medal of Honor, "For fundamental contributions to and leadership in developing the design and driving the early applications of the Global Positioning System." The current Global Positioning System (GPS) did not exist until 1995, just 22 years ago, and the engineer who led the project for the U.S. Department of Defense (DOD) was Mr. Parkinson. Parkinson, whose first job was delivering newspapers, had a passion for maps. He used those maps when canoeing to navigate the lakes and streams of Minnesota, aided by a hand compass. When he graduated from the U.S. Naval Academy in 1957 with a Bachelor of Science in Engineering, he joined the Air Force to study navigation systems. In 1960, when his superiors saw his engineering potential, they sent him to the Massachusetts Institute of Technology to pursue graduate studies. He became a protegee of Charles Stark (Doc) Draper, the father of inertial navigation, who was teaching at MIT at the time. Draper was the lead engineer developing the computer systems for NASA's Apollo program. [...] It was in 1972 when his path on inertial navigation collided with satellite systems. He had been recently promoted to colonel when he received a call from another colonel who was part of the Air Force inertial guidance "mafia." He moved to Los Angeles and joined the group, a bunch of Air Force engineers from MIT. Then Parkinson asked to work on the Air Force 621B program, the genesis of GPS.
