Top benefits of using robotic vacuums (Part 1)

Robotic vacuums have genuinely taken off over the last few years. It is straightforward to understand the reasons. With their practical, hands-free action and ease of use, homeowners have discovered various advantages of buying this type of cleaner. Still, are they worthy of a higher price? In this post, we have put together some prominent perks you can expect to get from using one.

Robot Vacuum Cleaners: What Are They?

They are an autonomous appliance designed for cleaning tiles, hard floors, and carpets of any dust and dirt, much similar to other kinds of vacuums. Their significant difference is that the robot can diminish the work amount that you need to do.

Since their release, they initially struggled with their homeowners. That said, after innovation, they have become more popular than ever.

Undeniably, in recent years, they have drawn endless interest. It is partly because they have been more affordable, yet mostly since they tend to be more efficient at completing the intended purpose – detailing your floors while not asking you to do much work.

Are you looking to purchase a vacuum? Then, you may do yourself a disservice without accounting for a cleaning robot. To help you decide whether it is a suitable device for your needs and wants, let’s have a closer look at their main benefits.

Easy To Use

Maybe the number one advantage of bringing home a robot vacuum is that it is usually simple to use. As soon as you programmed the machine for given spaces and set the timer for a start time, the robot will virtually run on its own. Put it on the floor in a proper starting spot and call it done.

Further, many units can self-regulate. You will not have to worry about its malfunctioning or getting stuck on a surface.

iPhone 2020 wireless data transmission

Apple is expected to use ultra-wide band technology to help devices transmit data at speeds of up to 500 Mb / s at a distance of 3m.

Technology blogger Ben Geskin has just released a series of photos that allegedly belonged to the iPhone 2020 (or iPhone 12). Apple’s new device is inspired by the iPhone 4 and will have significant improvements over the previous generation. Specifically, in addition to supporting the Wi-Fi 6 standard as the iPhone 11, the new device will integrate 5G connectivity, so the antenna slot on the side of the machine is wider than the old designs and made from other materials. This change comes from the fact that the connection system and 5G model are different from the old network technologies.

Besides, the “notch” on the iPhone 12 will also shrink because the new FaceID facial recognition hardware system will be smaller. Ben Geskin said Apple is experimenting with many FaceID solutions with different optical systems.

Changing the “rabbit ears” design is considered easy to understand. Apple’s FaceID technology is considered a branding feature but has become somewhat outdated compared to rivals. Instead of “Apple” cramming all the hardware on the top edge of the device, users expect them to shrink this “notch”.

The iPhone 12 may remove the Lightning port, but it won’t use USB type C like current Android models. Instead, the device will use UWB wireless technology (Ultra wideband, ultra-wide band) that allows data transfer rates up to 500 Mb / s in a distance of 3m and 110 Mb / s at 10m.

Earlier, Ben Geskin iPhone 12 would use three new overlapping circuit boards. This design aims to increase the internal space to accommodate other hardware, for example, 5G network components, while reducing the size of the device. From the iPhone X onwards, Apple’s phone models have used the arrangement of two overlapping circuit boards.

Earlier, analyst Ming Chi-Kuo said Apple could introduce next-generation iPhones with different screen sizes and all models support 5G. The 120 MHz ProMotion display on iPad Pro will also be included in the new iPhone. Besides, the smartphone launched in 2020 of “Apple” is also equipped with 3D camera and USB type C connector.

Facebook releases it plans for a News Tab

On Friday Facebook confirmed that publisher of The Wall Street Journal and other stories from News Corp will be delivered at a new “tab” which planned at the leading social network.

Facebook has confirmed that it will deliver News Corp stories in a departure from letting algorithms dictate users’ experiences through its longstanding practice and separate from the trademark news feed which will be edited by seasoned journalists.

Mark Zuckerberg Facebook co-founder and chief executive said in a statement provided to AFP  that people want to read high quality news on Facebook. They want to bring reliable news to their users.

He is excited we’ll have the opportunity to include US News Corp properties such as award-winning journalism from The Wall Street Journal in our news tab. No details about the agreement were provided.

Mari Melguizo Facebook spokeswoman said in a statement given recently to AFP that they started by paying a subset of publishers who can provide a steady volume of original and fact-based content including a range of topic areas. The number of publishers involved in the news tab will grow over time

Last month Facebook said that a portion of the publishers whose stories appear in a news tab set is planned to pay only to launch in the weeks ahead. According to the California-based online social network, the tab will be separate from the trademark news feed at Facebook which displays content from people’s friends and updates.

Facebook has confirmed plans in a departure from its longstanding practice of letting algorithms dictate users’ experiences for a News Tab will be edited by seasoned journalists. A human team will select top relevant, reliable breaking news stories.

Earlier Monday A Wall Street Journal report said that the estimated a quarter of 200 news organizations whose articles will be featured were planned to pay by Facebook.

The strange uses of vacuum cleaners

In addition to removing dirt on the floor as well as carpeting, the vacuum cleaner also has many uses that users don’t think of.

Clean pet hair

The main job of the vacuum cleaner is to suck all the pet hair that sticks to the carpet and on the floor. However, users are less likely to use vacuum cleaners to clean pets’ fur in the place where they live. Too much fur in a washing machine is one of the culprits that cause leaks and damage to the water pump system. Users should use a vacuum cleaner to vacuum carpets, blankets and sheets before putting them into the washing machine.

Insecticides

A Ohio State University study found that regular vacuuming would kill 96% of fleas (adults and larvae) indoors. Vacuum cleaners are also an effective way to remove dust mites and human skin cells they eat from mattresses.

Vacuum cleaners and vacuum cleaner accessories are a good way to catch spiders or mosquitoes in corners. After killing all insects, users paste a clean white cloth on the tip of the vacuum cleaner to remove spider web.

Refreshing upholstery, pillows and carpets

In addition to removing dirt, a vacuum cleaner and a baking soda box can remove odors and brighten the fabric. Simply, sprinkle baking soda on chairs, pillows, carpets and damp sponge to evenen the surface. Let baking soda penetrate the surface for at least an hour and then vacuum, users will see the fabric surface is brighter, the smell has been treated.

Reduce allergy in the house

Keep windowsills and crevices free of allergens by vacuuming regularly. Users should use a dust brush to vacuum the window to remove pollen and dust.
Users can use the dust brush accessory of the vacuum cleaner to remove dust on lampshades, books, lights, blinds and even leaves before cleaning with water. This eliminates the original dust layer, preventing dirt and stains from wiping away after wiping with water.

Cleaning of household appliances

Using a vacuum cleaner to remove dust, plaque from the power cord and refrigerator capacitors on the back will help the machine operate more efficiently and keep the temperature colder. For homes with additional dryers, usually a sauna dryer, a vacuum cleaner can be used to remove excess lint, the leading cause of home fires from the dryer ventilation system. Users should regularly remove the vent on the back of the dryer and use a vacuum to remove excess fibers and dirt.

Why OLED screen phones can cause eyestrain and headache?

Sometimes you experience eye strain, headache, for too long looking at an OLED screen, possibly due to something called Pulse Width Modulation (PWM). This article will help you better understand it.

OLED technology is widely used on smartphones for many advantages, such as dramatic contrast, deep blacks, thinner and lighter LCDs. However, OLED screen phones are using the method of reducing screen brightness as Pulse Width Modulation (PWM).

This is different from LCD screens that use DC dimming, and it makes some users feel uncomfortable. So how are they different? Why is PWM annoying a small group of us and DC dimming is not?

How does PWM work?

This technology simply means changing the width of the light pulses, thereby increasing or decreasing the screen brightness. The frequency of light pulses is often very high – 200Hz and above – making it impossible for the human eye to recognize each individual pulse. Therefore, we will receive the average amount of light that these pulses emit.

The state of the screen turned off or on is actually determined by the amount of light it receives. When you reduce the screen brightness, in fact, the off state lasts longer than it turns on, the amount of light generated by the pulses decreases so we think that the screen is darkened.

At 100% brightness, you notice it’s always bright because the pulse is at its widest. When reduced to 50%, the panel emits shorter pulses, divided into intervals that reduce the amount of light received. And if you continue to lower the brightness, the pulse amplitude will be shorter, the screen stays longer. At extremely low brightness levels, the spacing between the pulses is large enough for them to be discrete and visible to the human eye. At this time, flicker occurs.

Most people are not sensitive enough to recognize this screen flicker. Only a small group felt uncomfortable, although they did not know where the cause was. With this group, flicker for a long time makes the eyes faster tired, headache or migraine. Especially with the habit of using an OLED screen smartphone in low light conditions, or at times when the eyes should rest – for example, before going to sleep – is not as good.

Why don’t commercial planes fly higher into space?

The higher the flight, the more fuel-efficient the aircraft is, the faster and quieter it flies. But they can’t fly into space because of some design limitations.

According to ScienceABC, commercial aircraft usually fly stably at an altitude of 10,700 m above the ground. This is considered the ideal height to help airlines save money, fly faster and safer.

There are three main reasons for this.

The higher the flight, the thinner the air density. This helps reduce the drag of the aircraft. Besides, the air pressed down into the fuselage is also lower than the lifting air.

At the same time, the aircraft must also move faster to gain additional lift of the air. So when traveling at high altitudes, the aircraft will consume less fuel and fly faster.

Because of some design limitations, civil aircraft cannot fly into space.

Another reason is comfort. An aircraft can fly at altitudes of 10,700 – 42,000 m from the ground. Weather phenomena are most influential at altitudes of 0-10,700 m.

If flying at this altitude, the aircraft will not be affected by such turbulence weather. This helps passengers experience a softer and more comfortable flight.

The last reason is for everyone’s safety. In case the aircraft is at an altitude of 11,900 m and something happens to the engine, pilots will have more time to troubleshoot and contact the operating center before an emergency landing.

Most modern aircraft have very good incident response systems. People often think that when the engine is broken, the plane will free fall. But the truth is not so. The plane will hover forward.

Air turbulence due to terrain will not impact the aircraft if it reaches a safe altitude.

With each drop, the aircraft will hover 16-17 m to the front. Thus, from the time of engine failure at an altitude of 10,000 m until landing, the aircraft can go another 160 km.

This allows the pilot to fly the aircraft to the nearest airport for an emergency landing. Thus, flying higher will help the aircraft save, safer and faster.

Besides, flying at an altitude of 10 km above sea level will prevent the aircraft from hitting birds in the sky. Civil aircraft models can reach speeds over 900 km / h. Striking a bird could be equivalent to hitting a flying bullet at 1,220 km / h.
