Tv 8K – Japanese broadcaster NHK launched first channel
Television 8K – In Europe, TV providers are still boasting of HD programs. Meanwhile, the Japanese went a step (or even two) further. At the beginning of December 2018, the local broadcaster NHK launched the world’s first TV channel in 8K quality. What does it mean? Image resolution 7680 x 4320 (33.2 megapixels), supplemented by multi-channel sound 22.2. In the future, the BS8K station is to broadcast, among others direct broadcasts from the Olympic Games, which will take place in this country in mid-2020. So far, viewers can watch breathtaking shots for 18 hours a day. Filmed in the most beautiful corners of the Earth, and concerts of famous orchestras.

Intelligent lighting system – Infrared cameras and lasers

Intelligent lighting system – Cars that see at night. In winter, when the day is very short, the role of lights and the so-called Night driving assistants (image analysis of the thermal imaging camera allows you to mark on the screen, for example, animals or pedestrians) is obvious. In Mercedes, the intelligent ILS system with adaptive bi-xenon headlamps automatically adapts to weather, light and road conditions, including fog. Audi, in turn, uses long-range laser spotlights – the range reaches even several hundred meters in optimal conditions.

In the latest Maybach, so-called digital lights. The beam is reflected in them from the matrix composed of a million miniature mirrors. Two headlights allow – at least theoretically – to create a HD resolution image on a roadway. They not only better illuminate the road, but also improve the visibility of lanes or pedestrian crossings. They can also display pictograms of relevant signs directly on the asphalt. What does it give? On the asphalt, for example, a snowflake can be shown to warn others of the risk of slipping. The headlights communicate with the navigation. They match the lighting level of the road to what is currently located on it – cars, pedestrians, motorcyclists and of course corners and hills.

Active drive control – Faster overcome the bend

Active drive control – Active Torque Vectoring, or active torque control. It allows the internal wheels to be braked in the bend, while transferring the “moment injection” to the outer wheels. As a result, the car performs more efficiently and the driver has better control over it. The Subaru, which has equipped the Levorg model with the system, boasts.
Other brands, such as the Fiat, Jeep, and also the Range Rover, are equipped with separate modes that adjust engine operation, response to gas, brakes and gearbox (in the Jeep, combined in this way, there are up to 12 different systems) so that the car – with Snow mode enabled (snow) – maintained maximum traction and was able to run without any problems.

Intelligent power distribution – All-wheel drive

Intelligent power distribution – All-wheel drive

Intelligent power distribution – In many cars, the drive is electronically controlled, which allows better separation of torque between wheels. Some systems, as in the case of the Haldex system, redirect drive to the second axis when the sensors catch the slip.
In others – as in the xDrive system in BMW – the drive hits both axles. In normal conditions, i.e. when the grip is good or very good, 40% of the drive is directed to the front and the rest to the rear – BMW thus behaves typically sports characteristics. Torque, through a multi-plate clutch with a suitable control computer. It can be easily and continuously distributed in xDrive between axles – up to 100%, only for two wheels.
In Subaru, the drive was driven with semi-axles driving the wheels, which are the same length. This “symmetry”, according to the Japanese, greatly improves the confidence of running on curves, especially on slippery surfaces.

Interior heating – Heat from battery or pump

Interior heating – The car’s engine can be started remotely not only in the BMW 7 Series, where the key allows you to control the car on the touch screen. But also in Swedish Volvo produced for a cool climate. Pre-heating the cabin and cooling the windows will be easier in electric cars. At Nissan Leaf, or the latest Mercedes-Benz EQC, you do not need to run the engine for this purpose. Mercedes does not take energy to ventilate directly from the battery. The Germans have used a modern heat pump to reduce energy consumption.

Winter tires – Special compound of rubber and lamellas

Winter tires – Special compound of rubber and lamellas

Winter tires – The surface of the tire’s contact with the road surface is comparable to the A4 sheet. Driving on ice, snow or just on a wet but very cold road presents many challenges for tire manufacturers.

First of all, the rubber compound that the tire is made of. It must be flexible in the cold – the more the tread adheres to the surface, the better. Second, the shape of so-called lamellas or notches in the tread. They make the car better or worse on a slippery road that will not get out of the way, etc. In winter, it must provide traction and the shortest braking distance, but also the so-called drivability – driveability on snowy surfaces. Goodyear UltraGrip Performance tires, for example, have achieved this not only thanks to the use of special rubber. But also self-locking lamellas (literally biting into the ground). Does the hydrodynamic grooves discharge water from under the tire and increase the slip resistance on the so-called Water film (aquaplaning). These tires shorten the braking distance by up to 3%.

Technological metals – Term introduced in 2007

Technological metals – A concept that is relatively new, in contrast to the actual use of metals in science and industry. The date in 2007 was introduced by American chemist and physicist Jack Lifton. Since then, it is often used in industry. Generally, you can say that the tech. metals are basically precious metals and those that are necessary for the production of hi-tech devices and engineering systems. This category includes:

  • commercial production of miniature electronic devices
  • advanced military systems
  • generating electricity using alternative sources, for example solar panels or wind turbines
  • electricity storage using batteries and cells.

There are of course a lot of other uses of these elements. Almost all technological metals are a by-product of the treatment of basic metals (except for precious and lithium).

Supersensitive cameras – Detects threats for Earth

Supersensitive cameras – Will be the heart of the NEOSTEL ground-based telescope, whose task will be to detect dangerous for Earth objects. It will be part of the space situational awareness system (SSA) created by the European Space Agency (ESA). It’s about supervising space and tracking space objects. The NEOSTEL ground-based telescope is designed to help you with tasks that can detect various threats to objects Earth. The heart of the telescope will be the super sensitive CCD (Charge Coupled Device) cameras used for astronomical observations. Creotech Instruments S.A. is responsible for the development and production of cameras.
The cameras are cooled down to -50 Ā° C and maintained in a similar environment to the vacuum, so that when installed on the telescope it can observe the object of the size of a tennis ball, from a distance of 1000 km. This will not only detect asteroids that threaten Earth, but also space debris that can threaten functioning satellites and damage or destroy International Space Station (ISS).

VR may cause vomiting – Because of motion sickness

VR may cause vomitingĀ – Because of motion sickness – In order to fully enter the virtual reality,
one has to deceive not only the eyes but also the other senses.
This is also the reason why
many virtual reality users can cause problems with motion sickness.
Then the impressions
received by the liar do not agree with the visual stimulus.
In motion sickness,
the eyes see that the body is not moving, and that the labyrinth registers continuous motion,
tilting and acceleration, in the case of nausea caused by virtual reality is quite the opposite.

Eyes see the perfect simulation of space, covering the entire field of view.

However, the brain does not record any motion signals from the labyrinth or other senses.

In both cases there is a sensual dissonance that causes malaise, dizziness, fatigue,
and even vomiting.
