In this second installment of a two-part series on the Galaxy Z Flip’s Hideaway Hinge, we will take a look at another key innovation, which helps to protect the device from dust and dirt – the sweeper technology.
Keeping internal components clean is essential for maintaining the performance of a smartphone. The challenge of keeping dust and dirt out is even greater for foldable devices, as their designs include microscopic gaps between the body and the hinge.
In designing the Galaxy Z Flip’s hinge, Samsung engineers not only had to account for the spaces between the body and the hinge, but also meet three specific conditions: Elasticity (to account for shifts in the gap size); long-lasting flexibility (the hinge is tested to withstand 200,000 folds1); and slimness (to keep the device’s sleek form factor).
Finding a solution that protected against particles and met those conditions meant dozens and dozens of failed prototypes. But then, one of Samsung’s top engineers noticed that the way fibers were used in vacuum cleaners was similar to what was required for the Hideaway Hinge. The sweeper fibers were not only pliable enough to cover all the gaps as the smartphone folds and unfolds, they also remained flexible after long-term usage.
Now let’s take a look at how Samsung engineers overcame all those challenges and what the outcome of their efforts looks like.
As Nigeria’s aviation industry prepares for the resumption of domestic flights amid the COVID-19 pandemic, the Nnamdi Azikiwe International Airport in Abuja has acquired two robots with artificial intelligence (AI) features to improve passenger safety
A demo flight between Abuja and Lagos was conducted on Saturday by the airport as it observed compliance with safety measures put in place to reduce the spread of the coronavirus.
The News Agency of Nigeria (NAN) reported that hand wash and sanitisers were provided, temperature checks were conducted, and the rules of physical distancing were enforced.
At the departure lounge, the seats have been rearranged to increase spacing and instructions are placed to discourage passengers from using certain seats to urge them to maintain physical distance from others.
NAN also reports that two newly acquired machines, for the purpose of identifying passengers, had been stationed at the airport.
One of the highlights of the dry run test was the introduction of AI robots by Aerokeys Nigeria, an aviation service company, which successfully performed facial recognition.
The robots will also be used to reduce human contacts by performing repetitive tasks such as measuring body temperature, screening passengers, managing and sharing flight information, and generally enhancing compliance with the new airport protocols.
If they observe passengers with high temperatures attempting to board a plane, they will sound an alarm and identify the persons, the chief executive officer of Aerokeys Nigeria, Satumari Kudla told journalists.
“What we are trying to do is make our contribution to the fight against COVID-19 by bringing these robots to facilitate repetitive tasks in the airport environment,” he said.
Musa Nuhu, director-general of the Nigerian Civil Aviation Authority (NCAA), said on Thursday at the press briefing of the Presidential Task Force on COVID-19 that a new date for the resumption of flights will be announced following the Saturday demonstration. Monday, June 21, was initially fixed as a possible date but the NCAA said on Thursday, June 18, that it was no longer feasible.
Ethiopia’s communications regulator said on Friday it received twelve bids for the two telecom licences it plans to award to multinational mobile companies, breaking the state monopoly.
Nine bidders are telecom operators and two non-telecom operators, and one submission was incomplete, the regulator said.
Bidders include Etisalat, Axian, MTN, Orange, Saudi Telecom Company, Telkom SA, Liquid Telecom, Snail Mobile and Global Partnership for Ethiopia, a consortium of telecom operators made of Vodafone, Vodacom, and Safaricom. The two non-telecom operators are Kandu Global Telecommunications and Electromecha International Projects.
The issuing of licences will open up one of the world’s last major closed telecoms markets in the country of around 110 million.
The Ethiopian Communications Authority said the licenses will be awarded through a “competitive bidding process,” but did not clarify a deadline for it.
“This is the initial stage. We will soon have...the second stage,” said Balch Reba, director-general of the Ethiopian Communication Authority.
