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.

LAS VEGAS — Neighbors in the southwest part of Las Vegas are fed up over the wild scenes playing out in their area which have included flame throwers, rocket launchers, strippers and buses full of people as the Strip's night and day clubs remain closed.For weeks, Las Vegas police have been dealing with a sharp rise in complaints regarding "party houses," some of which have been the scenes for shootings and murders.Neighbors near one home on Sunset Road and Jones Boulevard say they are living next to a nightmare."It's a party going madhouse out here," Tony Grant said.Grant and his wife Nanette, who is battling breast cancer, say the for past six months, people have been arriving to their neighborhood by bus, car and rideshares.Videos shows dozens, if not hundreds, of people at the home, which at times includes laser light shows, loud music and nearly-naked women.Online, the venue is billed as a day and nightclub available for gatherings and parties for ,500 a day."There's fire-based entertainment, including flamethrowers, and rocket launchers that are being set off within obviously 10- to 15-feet of 50-foot pine trees and homes," Hadas Grant said.Online records show Las Vegas police have taken more than a half dozen reports for "disturbing the peace" in the 5800 block of Patrick Lane since April 2020.Records obtained by Clark County show authorities have placed administrative actions on the home, and fines have totaled 0.The Grants say the gatherings have continued."On the day the citation was placed on the door, that Tuesday night was one of the largest gatherings or events that they've ever had, they're laughing in the face of code enforcement," Tony Grant said.Interview requests to the group promoting the gatherings were not returned. But the home and the California-based owner are all over the county's radar with an active investigation, according to authorities."The girls that we see walking in and out, a lot of them are dressed in a G string and a top," Nanette Grant said.The Grants are fed up and fear it may only be a matter of time before one of the parties get really out of control, and someone gets hurt.Las Vegas police recently announced that at least 15 shootings and three other homicides at short-term rentals have occurred during recent months.This story was originally published by Joe Bartels on KTNV in Las Vegas. 2381
LA MESA, Calif. (KGTV) — La Mesa Police Department released body camera footage on Wednesday showing the events that led up to an arrest video that surfaced last week.About 30 seconds of the video provide by police starts without any sound. LMPD Chief Walt Vasquez said the beginning of the video is muted because of the way the body camera is activated. (See the video above and below.)Raw footage of bodycam footage would be released for four officers involved in the arrest of Amaurie Johnson on May 27, according to La Mesa Mayor Mark Arapostathis.Last week, video surfaced showing an argument between Johnson and an officer escalate at the Grossmont Trolley Station. The officer is seen pushing Johnson into a sitting position onto a bench during the video. Eventually, Johnson is handcuffed and told he is being charged with assaulting an officer.Vasquez added that the officer involved in the video has been an officer for about three years. He added that while Johnson was initially stopped for smoking in a trolley area, he wasn't charged with that when he was arrested.Johnson also denied in a separate press conference after city officials spoke that he was smoking. (Press conference below.)“For that situation to escalate the way it did, and for the cop, you know, to stand firm in his beliefs that I should be detained or taken in with no prior evidence or reasoning, I think that should be seen by the people,” Johnson told Team 10 investigator Adam Racusin.He said he was waiting for his friend at the trolley stop, near a building where that friend lives. He added that the officer started questioning him and that he gave the officer the information that he wanted.Johnson adds that he didn't resist or assault anyone."I feel as though people that look like me, um, feel the same way I do and we're tired of it. We're tired of having to deal with stuff like that,” Johnson said.The video prompted the city to begin a special investigation into the incident and LMPD to place the officer involved on administrative leave pending the investigation. 2072
Leaders of the world’s most powerful nations wrapped up the Group of 20 summit on Sunday, vowing to spare no effort to protect lives and ensure affordable access to COVID-19 vaccines for all people.The two-day summit of heads of state was held virtually due to the coronavirus pandemic, which has killed at least 1.38 million people globally, with the world’s highest death tolls recorded in seven of the G-20 countries. The virus has wiped out hundreds of millions of jobs globally and plunged millions into extreme poverty.The virus “revealed vulnerabilities in our preparedness and response and underscored our common challenges,” the G-20 said in a final statement that focused heavily on battling the coronavirus, enhancing environmental protections and supporting the global economy.The group vowed “to spare no effort to protect lives.”The G-20, which includes the U.S., India, China, the U.K., France, Germany, Japan and others, also stressed the importance of global access to COVID-19 vaccines, drugs and tests.“We will spare no effort to ensure their affordable and equitable access for all people, consistent with members’ commitments to incentivize innovation,” the statement said.The G-20 expressed support for efforts like COVAX, an international initiative to distribute COVID-19 vaccines to countries worldwide. The U.S., however, has declined to join under President Donald Trump.German Chancellor Angela Merkel told reporters Sunday in Berlin after the virtual summit that Germany had given financial support to the COVAX initiative, but that more money was needed.The G-20 statement did not directly address an urgent appeal by U.N. Secretary-General Antonio Guterres, who said billion in additional investment is needed for mass manufacturing, procurement and delivery of new COVID-19 vaccines around the world, including billion immediately.There is also concern that countries such as Britain, the U.S., France and Germany have directly negotiated deals with pharmaceutical companies, meaning that the vast majority of the world’s vaccine supply next year is already reserved.“Fortunately, there’s now hope for vaccines,” Merkel said, adding that “it is important that not only Europe secures vaccines, as the European Union is doing now, but ... that it is important for the entire world” to have access to vaccines.She said it is important that COVAX starts negotiating with the producers of potential vaccines based on the money it already has, but that she was somewhat worried those negotiations had not happened yet.Saudi Arabia’s King Salman rounded out the summit, saying the G-20′s final statement “succeeded in sending out a message of hope and reassurance to our citizens and all people around the world.”“This is what the world has been expecting from us. This achievement today is a culmination of our joint efforts throughout this challenge-fraught year,” the Saudi monarch said.Saudi Arabia presided over the G-20 this year and was host of the virtual summit, which was originally intended to be held in-person in Riyadh before the pandemic. During the Saudi king’s speech, small video squares showed the leaders of Germany, France, the U.K., Canada, South Korea, China, India and South Africa watching the final remarks. Trump participated in the summit with prerecorded speeches, but was not in attendance for the virtual summit’s conclusion.It appeared all G-20 countries agreed to the full content of the final statement, with the exception of Turkey, which was due to give a press conference later Sunday explaining further.Delegates from the G-20 had convened virtually throughout the year to discuss the coronavirus, agreeing to suspend debt payments for the world’s poorest nations until mid-2021 to allow those countries to focus their spending on health care and social support programs. The G-20 called on private lenders to join the effort.Already, 46 countries have requested to benefit from the debt suspension initiative, amounting to .7 billion in debt referral. The U.N. secretary general, however, has called on the G-20 to extend debt repayments through the end of 2021 and expand the scope to middle-income countries in need.G-20 countries are allowing low-income countries with unsustainable debts to apply for permanent debt relief on a case-by-case basis.In final remarks at the summit, Italian Premier Giuseppe Conte laid out his country’s objectives for the G-20 next year as it assumes the rotating presidency from Saudi Arabia.“The existential threat, represented by climate change, soil degradation and by the decline of global biodiversity, has brought us to a crossroads, which will determine if we are able to save our planet and construct a sustainable future,” Conte said.Conte said the pandemic will continue to be at the top of the group’s agenda and reiterated his support for universal access to vaccines.___Associated Press writers Kirsten Grieshaber in Berlin and Frances D’Emilio in Rome contributed to this report. 5010
