Bicycle tires may have seen little technological development over the past decades, especially in terms of design, but a recent innovation could change this trajectory and confirm the adage of “reinventing the wheel.”

American company Smart Tire, in collaboration with NASA, announced a new model of airless tires that innovatively uses the ability to remember their original shape when exposed to pressure!

What’s new?

Unlike many traditional runflat tires, which often come for rider comfort and are criticized for their stiffness, rolling resistance and high effort required when pedaling, inside the new tire is a coiled cord called a “medl”. In rubber tire design..

This wire is NiTinol, a combination of nickel and titanium, which is unique in its combination of strength (due to the nickel) and rubber-like elasticity.

The tire’s exposure to pressure causes deformation of its shape, but it returns to its original state due to the materials it is made of. This feature allows Metl tires to provide the same compression and rebound dynamics as conventional pneumatic tires.

Other benefits

Coating the Nitinol spring with a polyrubber material creates transparent sidewalls and makes the tire tread (the rubber on the tire in contact with the road) flexible.

It is also worth noting that a metal tire requires half the amount of rubber as a regular tire. Although its tread needs to be replaced after 8,000 to 12,000 km, the basic tire is designed to last the life of the bike.

Technology inspired by NASA

This innovative approach is called “SMART” (Shape Memory Alloy Radial Technology) and aims not only to redefine the quality of bicycles, but also to extend it to a wide range of off-road vehicles.

Although this technology was originally designed by NASA to address the challenges faced by extraterrestrial exploration, particularly missions to Mars, it has found a transformative application on Earth.

Experts say these futuristic designs could offer flexibility in tightness by allowing controlled air inflation, making them act like compressed air.

Such advances in tire technology, eliminating flat tires, regular monitoring of air pressure and reduced maintenance requirements, represent a major advance in the world of cycling.

Microsoft has started rolling out the major Windows 11 update, version number 22H2, which comes with major security improvements along with many great features, the most important of which are based on advanced techniques of artificial intelligence generation.

Last week, Microsoft held an event where it revealed the most important improvements and new tools coming in the current Windows 11 2023 update, and the company confirmed that the update will start reaching users today, Tuesday, September 26. .

The company has confirmed that these new features will be rolled out in waves, starting with people who activate “early feature access” in the Windows 11 update.

If you have these, you should start receiving notifications of new updates for the system, and by clicking on them, you’ll start seeing Microsoft Preview, which includes many new features and improvements that the company is testing. system over the past few months.

Many new features rely on AI, including a new Intelligent Assistant tool, and updates to in-box apps that improve AI capabilities.

The most interesting tool is the AI ​​Copilot program, which was announced in May as a replacement for the Cortana voice assistant and is built with OpenAI’s latest GPT-4 artificial intelligence capabilities, which help generate and answer complex questions based on user criteria.

The new Windows 11 update has many features, including:

• Copilot Intelligence Assistant.
• Updated the file browser interface.
• AI suggestions in the file browser’s start menu.
• Update the paint scheme.
• AI text recognition in crop tool.
• Refresh Notepad.
• Completely revamped settings homepage interface.
• Dynamic lighting to identify and control connected lighting units
  Upgrade the image viewing program.
• New backup software.
• Integration with cloud computing.
• And many other features.

It is worth noting that this Windows 11 update is not an expected update, it will carry the version 23H2 that Microsoft tested several months ago, which is also 22H2, a company spokesperson told the media, and the company will wait for everything. New features coming before version 23H2. This means another big update is coming. .
