U.S. Researchers Develop A Vacuum-Assisted Toilet for Flight Passengers

They added additional pipe to increase the distance between the toilet bowl and the flush valve and made the pipe attachment at the bowl more of a gradual bend as opposed to a sharp 90-degree angle.

Airplane toilets are loud. For kids, they could be downright terrifying. Now, a team of US researchers has invented a vacuum-assisted toilet that is about half as loud as the regular airplane commode.

“People have told us they don’t want their kids to be scared to use the bathroom on a flight,” said lead researcher Kent Gee, Professor at the Brigham Young University. “We’ve used good physics to solve the problem.”

It’s been a really hard problem to solve because getting airplane toilets to flush with very little water requires a partial vacuum, which at 38,000 feet, pulls air at nearly half the speed of sound.

According to the research, conducted in a lab, an air-water mix in vacuum-assisted toilets travels more than 300 miles per hour.

When things move at that speed, any disturbance at all to the flow — like the bend of a pipe or a valve — generates significant noise.

Now that airplanes come with much quieter interiors, toilet flushes reverberate more throughout the cabin.

However, tests of the new contraption show aeroacoustically-generated noise declined 16 decibels during the flush valve opening and about 5-10 decibels when the valve is fully opened, the researchers reported in the Proceedings of Meetings on Acoustics journal.

To solve the problem, the team focused on three valve conditions during the flush cycle: the initial noise level peak associated with the flush valve opening, an intermediate noise level plateau associated with the valve being fully opened and the final noise level peak associated with the flush valve closing.

Aiming to work better on camera technology, Chinese handset maker Xiaomi has registered a research and development company in Tampere, Finland, the media reported.

It also decided to tap into Finnish camera expertise by founding a new company in Finland or more precisely, two companies, Xiaomi Finland Oy and Xiaomi Technology Finland Oy, tech portal nokiamob.net reported on Friday.

Notably, the Finnish town of Tampere houses have some of the world’s best camera experts.

The handset maker’s new business activities in Tampere would focus on product development, however, it would initially start with camera technologies.

“Xiaomi follows the steps of Huawei and is finding Finland as an attractive source of skilled labour. Huawei became a new home to lots of former Nokia experts and after partnering with Leica, Huawei devices now have a reputation of being the best or among the best camera phones on the market. Xiaomi is probably hoping to achieve the same thing,” the nokiamob.net report added.

In September 2016, Chinese tech titan, Huawei opened a research and development facility in Tampere.
