Whether you live in a city of somewhere more rural, there are always things in the air, invisible to the naked eye that could make you sneeze or cause major illness. Detecting these microscopic materials such as pollen, mold and pollutants could be time consuming and costly. A lab at the University of California, Los Angeles is trying to solve that problem by developing a handheld allergen detector for consumers. VOA’s Elizabeth Lee has the details.

The Circus Maximus Experience, opened in Rome this week and offers visitors the chance to relive the ancient splendors of chariot racing in the Imperial period of Rome through augmented and virtual reality. The innovative project implements interactive display technologies never before used in such a large outdoor area.

“Now you find yourself in front of the Arch of Titus, which was possibly built in the place of a more ancient arch and dedicated in the year 81 After Christ by the Roman Senate and people to Emperor Flavius”.

This is just an example of what modern-day visitors will be listening to in their headsets, while at the same time through special visors see a virtual rendering of the majestic 20-meter Arch of Titus in Rome’s Circus Maximus.

Thanks to a ground-breaking project using interactive display technology never before used in such an extended outdoor area, visitors are able to re-live the life in one of Rome’s undisputed landmarks.

Visitors immerse themselves in history for with overlapping images from the past and those of the reality of today. They are able to visualize architectural and landscape reconstructions of what life was like during all of the historical stages of the Circus Maximus.

They can see the ancient Murcia Valley enriched with buildings and walk around in the Circus among the shops of the time. They can visualize the Circus during Imperial times, the Middle Ages and in a more modern age.

The full itinerary involves eight stops including: the valley and the origins of the Circus, the Circus from Julius Caesar to Trajan, the Circus during the Imperial age, the cavea or tiered seating arena, the Arch of Titus, the tabernae or shops, the Circus during the Middle Ages and modern age, and lastly “A Day at the Circus” for an experience of the exciting chariot race of the quadrigas with the screams of incitement of the public and the overturning of wagons.

Visitors are able to enjoy similar experiences in Rome at the Baths of Caracalla, the Ara Pacis and the Domus Aurea.

In a building a few miles from Google and Facebook’s plush campuses is the Pentagon’s sparse outpost in Silicon Valley.

Here, military personnel and civilians look for commercial technology that can help the armed services solve problems they face in the field.

That could be working with a local commercial rocket company to deploy satellites faster. Or finding an up-and-coming firm that has created a novel communication system that works in some of the harshest conditions.

Defense Innovation Unit

Founded four years ago, the Defense Innovation Unit has a sense of urgency now more than ever, says its director, Michael Brown, formerly chief executive of Symantec, the cyber security firm, and of Quantum, a computer storage firm.

Because of the new so-called Tech Cold War, tensions are surging between the U.S. and China over emergent technologies, such as 5G mobile phone networks, artificial intelligence and autonomous driving.

“The Defense Innovation Unit’s mission has never been more critical, given the tech race that we’re in with China, than it is today,” Brown said.

Chinese investors and companies also are here, for many of the same reasons — to find the breakthroughs that will help their nascent and growing tech industry. But they’re presence is under increasing scrutiny, fueled by a concern that Chinese investors and companies are part of a system of transferring technology out of the U.S. and into the hands of an adversary, the Chinese government.

Raising alarms

Brown is the co-author of a report that shed light on the growing presence of Chinese firms and investors in Silicon Valley and raised alarms over whether the U.S. was in danger of losing key technology to the Chinese. 

The U.S. government has expanded its restrictions on Chinese companies buying firms deemed to hold key technology. And Chinese investors are finding it harder to be part of funding rounds of U.S. startups.

“Investors have become much more sensitive to the issue,” said Rebecca Fannin, author of “Tech Titans of China.” “They’re more cautious about investing.”

​Mixed reception

Some in the tech industry are skeptical of working for either the Pentagon or Chinese companies and the Chinese government. Employees at Google this year pushed back on projects involving both.

Brown’s job is two-fold. With his deep ties in the tech industry, he helps find technology that might help the military. He is also an ambassador of sorts for the Pentagon in Silicon Valley, building a bridge to tech firms large and small.

“For areas like artificial intelligence or cyber, we need those companies more than they need us,” he said. “But when we’re talking about smaller companies that are trying to get off the ground, get to their first $100 million in revenue, they’re interested in large customers. So, we have found no reluctance at all, in fact, enthusiastic response that they participate in our solicitations.”

American tech companies have long argued for the same access to China’s market that Chinese companies have here, for a “level playing field.” That hasn’t happened yet, but some are skeptical that disengaging from the Chinese economy is the right approach.

Vigilance, engagement

At a recent event by the Asia Society Northern California, investors, former tech executives and intellectual property experts discussed the conflict with China. Engagement with China has worked, argued Andy Rothman, an investment strategist at Matthews Asia, an investment firm, even if there is still a lot China hasn’t done that it said it would do.“The level of personal freedom that the Chinese people have today is dramatically better than it was 30 or 40 years ago and part of that is due to engagement with the rest of the world,” Rothman said.

For Brown, the issue isn’t how far China has come. It’s about the U.S. maintaining its technology edge and getting tech firms to think twice about working with the Chinese, even though the country represents a huge, largely untapped market.

“We do not share the same values as the Chinese Communist Party,” he said. “We need to be aware of that as we’re looking to make the next dollar. There’s other things at stake.”

However the trade war is settled, the ongoing tensions over whether there will be one or two tech super powers likely will remain.

British and Japanese mobile phone companies said Wednesday they’re putting on hold plans to sell new devices from Huawei, in the latest fallout from U.S. tech restrictions aimed at the Chinese company.

Britain’s EE and Vodafone and Japan’s KDDI and Y! Mobile said they are pausing the launch of Huawei smartphones, including some that can be used on next generation mobile networks, amid uncertainty about devices from the world’s No. 2 smartphone maker.

The U.S. government last week restricted technology sales to Chinese telecom gear suppliers because of alleged security risks, though telecom carriers got a 90-day grace period to let them find other suppliers. The sales ban is part of a broader trade war between Washington and Beijing.

British mobile chip designer Arm said separately it was complying with the U.S. rules, after the BBC reported it was suspending business with Huawei — a move that could hobble the Chinese tech company’s ability to produce chips for new devices.

Vodafone said in a statement that it’s “pausing pre-orders” for the Mate 20X, Huawei’s first phone for 5G networks, as “a temporary measure while uncertainty exists regarding new Huawei 5G devices.”

EE CEO Marc Allera said sales would not resume until it gets “the information and confidence and the long-term security” that customers will be supported over the device’s lifetime. The company was also set to sell the Mate 20X followed by Huawei’s Mate X folding handset.

EE said it’s working with Huawei and Google, which makes the Android mobile operating systems to make sure it “can carry out the right level of testing and quality assurance.”  

The Trump administration’s order last week cuts Huawei’s access to American chips and Google, which makes the Android operating system and services for its smartphones.

Y! Mobile, owned by Japanese technology company Softbank, said sales of the Huawei P30 lite, set for May 24, have been delayed, and advance orders were canceled.

SoftBank spokesman Hiroyuki Mizukami said the company wants its “customers to feel safe using our products.”

KDDI also indefinitely delayed its sales, initially set for late May.

It’s unclear when, or if, the companies will lift the sales freezes.

British carriers plan this year to roll out 5G services while Japan will follow in 2020. Fifth generation mobile networks will enable superfast downloads and pave the way for new innovations like connected cars and remote medicine.

Arm, which is also owned by Softbank and designs mobile microprocessors that power most of the world’s smartphones and tablets, said it “is complying with all of the latest regulations set forth by the U.S. government.”

The company told employees to halt all business deals with Huawei, the BBC reported, citing a company memo that said its designs contained “U.S. origin technology.”

In response to the report on Arm, Huawei said it recognizes that some of its partners are under pressure as a result of “politically motivated decisions” but that it’s “confident this regrettable situation can be resolved.”

The giant U.S. internet search engine Google said Monday it is restricting China’s Huawei from access to its Android operating system in compliance with the Trump administration’s blacklisting of the world’s second biggest smartphone maker as a national security threat.

Google said it is “reviewing the implications” of last week’s order requiring export licenses for technology sales to Huawei.

The U.S. and Chinese companies said millions of Huawei phones already in use around the world would continue to have access to such popular Google services as Gmail, YouTube and maps.

But last week’s U.S. order would curb the future transfer of hardware, software and services to Huawei, possibly limiting the Chinese company’s expansion globally and its efforts to overtake South Korea’s Samsung as the world’s biggest smart phone manufacturer.

Google services were already banned in China, so analysts say the impact of the curb on technology sales could mostly affect Huawei’s international sales, making its phones less attractive to customers if they do not have Google features. Last year, Huawei sold nearly half of its production of 208 million smart phones overseas and the rest in China.

“Huawei will continue to provide security updates and after-sales services to all existing Huawei and Honor smartphone and tablet products, covering those that have been sold and that are still in stock globally,” a Huawei spokesman said.

The Chinese firm is at the center of ongoing trade disputes between Washington and Beijing. The U.S. contends that Huawei’s technology could be used to spy on Americans, allegations Huawei has repeatedly denied.

China and the U.S. are in the midst of months-long trade talks with the world’s two biggest economies engaging in tit-for-tat tariff increases on hundreds of billions of dollars worth of each other’s exports.
