SAN FRANCISCO (AP) — Schools across the United States are facing shortages and long delays in getting laptops and other equipment needed for online learning. They are this year’s most crucial back-to-school accessories. Part of the reason is high demand and disruptions of supply chains that have jammed production of laptops and Chromebooks made by Dell, HP, Lenovo and other brands. Schools say another critical reason is the Trump administration’s recent sanctions on Chinese companies that have exacerbated massive backlogs. Educators nationwide worry that computer shortfalls will compound inequities. They also warn of headaches for students, families and teachers. 679

SAN ONOFRE (CNS) - Authorities Thursday were searching for a hit-and-run motorist who struck and killed a pedestrian on Interstate 5 in the far northern reaches of San Diego County.Dispatchers received a call shortly before 6:40 a.m. from a person who reported seeing a body off of southbound Interstate 5 just south of Cristianitos Road, California Highway Patrol Officer Kevin Smale said.Officers responded to the area and found a pedestrian lying near the highway, Smale said, adding that the victim was pronounced dead at the scene.No details about the victim or the vehicle involved were immediately available.Officers shut down the onramp from Cristianitos Road to southbound I-5 and the right two lanes of southbound I-5 north of Basilone Road to investigate the circumstances leading up to the crash.Anyone with information regarding the crash was asked to call the Oceanside CHP office at (760) 643-4300. 921

SAN FRANCISCO (AP) — The robotic car company created by Google is poised to attempt a major technological leap in California, where its vehicles will hit the roads without a human on hand to take control in emergencies.The regulatory approval announced Tuesday allows Waymo's driverless cars to cruise through California at speeds up to 65 miles per hour.The self-driving cars have traveled millions of miles on the state's roads since Waymo began as a secretive project within Google nearly a decade ago. But a backup driver had been required to be behind the wheel until new regulations in April set the stage for the transition to true autonomy.RELATED: 2018 could be a pivotal year for driverless carsWaymo is the first among dozens of companies testing self-driving cars in California to persuade state regulators its technology is safe enough to permit them on the roads without a safety driver in them. An engineer still must monitor the fully autonomous cars from a remote location and be able to steer and stop the vehicles if something goes wrong.California, however, won't be the first state to have Waymo's fully autonomous cars on its streets. Waymo has been giving rides to a group of volunteer passengers in Arizona in driverless cars since last year. It has pledged to deploy its fleet of fully autonomous vans in Arizona in a ride-hailing service open to all comers in the Phoenix area by the end of this year.But California has a much larger population and far more congestion than Arizona, making it even more challenging place for robotic cars to get around.RELATED: NTSB report: Uber self-driving SUV saw pedestrian in Arizona but didn't brakeWaymo is moving into its next phase in California cautiously. To start, the fully autonomous cars will only give rides to Waymo's employees and confine their routes to roads in its home town of Mountain View, California, and four neighboring Silicon Valley cities — Sunnyvale, Los Altos, Los Altos Hills, and Palo Alto.If all goes well, Waymo will then seek volunteers who want to be transported in fully autonomous vehicles, similar to its early rider program in Arizona . That then could lead to a ride-hailing service like the one Waymo envisions in Arizona.But Waymo's critics are not convinced there is enough evidence that the fully autonomous cars can be trusted to be driving through neighborhoods without humans behind the wheel.RELATED: Potential "game changer" could make commutes more relaxing"This will allow Waymo to test its robotic cars using people as human guinea pigs," said John Simpson, privacy and technology project director for Consumer Watchdog, a group that has repeatedly raised doubts about the safety of self-driving cars.Those concerns escalated in March after fatal collision involving a self-driving car being tested by the leading ride-hailing service, Uber. In that incident, an Uber self-driving car with a human safety driver struck and killed a pedestrian crossing a darkened street in a Phoenix suburb.Waymo's cars with safety drivers have been involved in dozens of accidents in California, but those have mostly been minor fender benders at low speeds.RELATED: Waymo self-driving car crashes in ArizonaAll told, Waymo says its self-driving cars have collectively logged more than 10 million miles in 25 cities in a handful of states while in autonomous mode, although most of those trips have occurred with safety drivers.Waymo contends its robotic vehicles will save lives because so many crashes are caused by human motorists who are intoxicated, distracted or just bad drivers."If a Waymo vehicle comes across a situation it doesn't understand, it does what any good driver would do: comes to a safe stop until it does understand how to proceed," the company said Tuesday. 3827

SAN FRANCISCO (AP) — The University of California has accepted a record number of freshmen and transfer students that includes the most ever from California for the 2019-20 academic year.The university system said Monday its nine undergraduate campuses accepted 71,655 California freshmen and 26,700 students who will transfer from California community colleges. That's more than 3,200 California students than last year.UC schools have been under pressure to accept California residents so they can have a cheaper way to complete a four-year degree at the state's top public universities.Nearly 218,000 prospective undergraduates applied for at least one UC school for fall 2019 during the application period that ended Nov. 30, according to figures released by the university system. They include about 177,000 applications to become freshmen. 853

SCRIPPS RANCH (KGTV): The "shake table" at UC San Diego will soon be able to move just like a real earthquake, thanks to a grant from the National Science Foundation.Researchers at UC San Diego received .3 million for upgrades to the machine."This would become one of the very best centers for earthquake engineering worldwide," says Professor Joel Conte, who teaches in the school's Department of Structural Engineering.Researchers say, right now, the shake table only moves back and forth, rocking large structures placed on top of it. With the grant, they'll be able to change the hydraulics on the machine. Once completed, it will shake back and forth, left and right, up and down and will also pitch, roll and yaw."We'll be able to reproduce real earthquake ground motions much more realistically, much more accurately, and much more completely," says Conte.Building designers and researchers use the shake table to test how structures will react to an earthquake, what kind of damage they'd sustain and whether or not they'd be usable immediately afterward.The shake table can hold multi-story buildings, bridge columns, wind turbines and more. The first structure scheduled to be tested after the upgrade is a 10-story building made from cross-laminated timber.According to the school, the money from the grant will add "new hydraulic pumps, a cooling tower and very large accumulator banks for the facility’s hydraulic-powered system. It will cover the costs of reconfiguring the existing two horizontal actuators, adding another two horizontal actuators, and powering the six vertical actuators to generate table motion."Researchers say it will be the most modern, functional shake table in the world."As soon as it can move in several directions, we will be able to serve all these needs," says Conte. "In the past, the industry in California often had to go to Japan, to China, to Korea. That will not be the case anymore."Construction on the upgrades will start in February of 2020 and be complete by July of 2021. 2042
