Interestingly, ordinary Wi-Fi can easily identify weapons, bombs and explosive chemicals in bags just anywhere, be it a crowded stadium, or museums, theme parks, schools and other public spaces, a new study reveals.
The researchers’ suspicious detection object is easy to set up, reduces security screening costs and avoids invading privacy such as when screeners open and inspect bags, backpacks and luggage. Traditional screening generally requires high staffing levels and costlier specialized equipment.
“This could have a great impact in protecting the public from dangerous objects. There’s a growing need for that now”, said study author, Yingying Chen.
The study reveals that Wi-Fi, or wireless, signals in most public places can penetrate bags to get the dimensions of dangerous metal objects and detect them, including weapons, aluminium cans, laptops and batteries for bombs. Wi-Fi can also be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosives.
This low-cost system requires a Wi-Fi device with two to three antennas and can be integrated into existing Wi-Fi networks. The system analyzes what happens when wireless signals penetrate and bounce off objects and materials.
Experiments were done with 15 types of objects and six types of bags demonstrating detection accuracy rates of 99 percent for dangerous objects, 98 percent for metal and 95 percent for liquid. For typical backpacks, the accuracy rate exceeds 95 percent and drops to about 90 percent when objects inside bags are wrapped.
“In large public areas, it’s hard to set up expensive screening infrastructure like what’s in airports. Manpower is always needed to check bags and we wanted to develop a complementary method to try to reduce manpower,” concluded Chen.
Next steps include trying to boost accuracy in detecting objects by imaging their shapes and estimating liquid volumes.
The study was performed at Rutgers University, New Brunswick. It also received the best paper award at the 2018 IEEE Conference on Communications and Network Security on cybersecurity. (IANS)
As the Omicron variant threat looms, Google is reconsidering its plans to ask full-time employees to return to offices by January 10. According to an email from Google VP Chris Rackow, seen by CNBC, Google will not be requiring its employees to return to offices on January 10 as expected after all. The company has changed its return to work plans several times as the pandemic evolved.
In August, when the delta variant was a top concern, Google had announced plans for hybrid return-to-work till January 10, 2022. Rackow said in the email that full-time employees will wait until the new year to assess when US offices can safely return to a "stable, long-term working environment. "None of the US locations will adopt the hybrid working mandate on January 10 as planned," he added. Rackow said that Google will allow specific locations to decide their timelines for returning their respective local workforces to the office.
Apple is reportedly asking employees to return to offices starting February 1 as part of a hybrid work pilot who will be able to work remotely for four weeks a year. After the first US case of the Omicron Covid-19 variant was reported in California, the federal government was set to announce a bunch of measures to help counter the virus, including campaigns to increase vaccinations and booster shots, additional testing requirements for travellers entering the country from abroad and plans to make rapid at-home coronavirus testing free for more people. International travellers coming to the US will have to test within a day of departure, regardless of vaccination status, rather than the 72 hours currently required for vaccinated travellers, under new protocols early next week. The new testing rules will apply both to US citizens and foreign nationals entering the country. (IANS/ MBI)

Life was moving at a fast pace for most of us and then the pandemic hit. The pace definitely slowed down and gave us an opportunity to look back at our lifestyle, routine and our most cherished old memories. 'Looking back' through your old photos on a phone versus flipping through a glossy photo album and reliving each memory? Getting teary eyed at some, and straight up howling with laughter at some others.
Today, advancement in technologies has opened up an ocean of possibilities. So how does one hold on these closest moments and memories in a thoroughly tangible way? Sachin Kataria, CEO, Zoomin shares all the minute details to make festive season personal.
Moving from gifts to personal stories: Gifts are no longer just confined to material items of a certain 'price tag'. Gifting someone is now seen as a chance to create a unique experience and splash of emotions that the receiver can enjoy for years to come. It's a fact that preserving memories is now a lot easier with delivery partners that can convert digital memories into actual personalised frames, albums and a host of memorabilia. And this makes it so much easier and quicker for you to hold meaningful memories close to your heart.

Reframing moments of joy: It isn't always possible to create a photo album or a photo frame of all your special moments or even gift them all the time. This is where new age personalized gifting platforms are a boon. It is now possible to add a touch of personalization to any gift item making it that much more special and meaningful for both the giver and the receiver. One can choose from functional items such as coffee mugs or calendars to more stylized gifts like Canvas Prints and Photo décor and add a favorite memory to make the gift item personal and more valuable.
