Bridgestone tires will tell you about road conditions

The car tires used to be just rubber on a steel wire frame. For a few years now, every piece of equipment has become more and more advanced and more and more sensors appear in it. In addition to pressure sensors, we will soon have additional sensors that will tell us the conditions of the road.

Tire engineers from Bridgestone have developed a new type of sensor called Contact Area Information Sensing, which is installed on the inside of the tire, to monitor its interaction with the surface, providing drivers with real-time data on road conditions.

Technology has been developing since 2011 and was presented at the Frankfurt Motor Show at the time, and its first generation used a load-sensing sensor and lateral forces acting on the tire. A little later, CAIS 2 appeared, which was equipped with additional acceleration sensors that were used to determine the condition of the pavement. In 2014, Bridgestone showed CAIS 3, the latest generation of system, plus the ability to monitor the condition of the tire itself.

Now the Bridgestone management has announced the commercialization of CAIS 2, which it intends to use in passenger car and truck tires. They will be equipped with an accelerometer attached to the inner wall of the tire, which will be powered by an electromagnetic generator.

The solution will monitor high frequency vibrations on the tire and then transmit information via radio to the central module installed in the vehicle. There, using special algorithms, will be translated into information about current road conditions.

In this way, the driver will know in real time whether the road surface is moving, dry, wet, wet, covered with fresh snow, snow or ice. This is undoubtedly a very useful solution, as it is often difficult at first sight to notice that the surface can be slippery, and particularly tricky is the so-called. Black ice.

Samsung and Google will expand Nexus

Nexus 7 slowly conquers the market by tempting consumers with high functionality and low price. But many believe the 7-inch screen is too small for them, so plans are for a new, much larger tablet model.

According to unofficial reports released by CNET analyst Richard Shim, Google along with Korean Samsung is developing a new, larger version of Nexus, which would have a 10-inch screen and would offer a screen resolution of 2560×1600 pixels, beating the head of the new iPad. A pixel density of 299 ppi.

Shim claims that the reports are reliable because they come from component suppliers and those in those cases are the best informed source.

The specialist also claims that in December, the production of a new tablet for Android should start at $ 99. It is not known if this will be a Nexus 7 variant, or a brand new model.

If the information is confirmed, it would be a great curiosity. As we all know, Nexus 7 is a work of Asus, so you might think that Asus will also be producing a larger model. Meanwhile, Samsung’s involvement suggests that Google is seeking to diversify its interests and does not want to bind to one partner.

Steam Machines will be the least profitable hardware

The Steam Machines project was supposed to be an attempt to introduce PCs to our showrooms. However, this may not be a good attempt, as industry insiders suggest that you can not earn much on this hardware.

PCs have for years been trying to compete with consoles in the entertainment field, trying to take over the video game market. The Steam Machine was meant to be a combination of the features of both devices, so to provide PC functionality with console comfort and the ability to play with the controller in the palm of your hand while sitting on a comfortable couch.

After presenting pricing models of individual manufacturers enthusiasm fell heavily when it turned out that the cheapest model Steam Machine cost over $ 700, while the most expensive one has to pay over $ 2,000. This is the amount you can buy a heavily developed gaming computer with no restrictions on the Steam OS Linux based Steam Steam operating system.

It is no wonder that the last days of Steam Machines seemed to be forgotten, especially as the companies involved in the production of these devices now claim that the profits from this market will not be too great. For example, Frank Azor, Alienware’s chief manager, admitted that this is his least profitable venture.

Even worse, some other companies from almost 13 involved in the idea, who have agreed to cooperate mainly because it is a venture of Valve. Now it seems that they can get a great deal on it, especially since the multitude of available configurations can make consumers have trouble making a specific choice.
