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.

We observe transactions but we do not know who is behind them

The Bitcoin Virtual Currency changes the economics of crime by providing encrypted fraud, an almost anonymous payment system independent of any central bank. The victim of ransomware – a malicious software that encrypts files and requires payment for their unlocking – receives a unique account affected by bitcoins. After getting some ransoms, some gangs pour bitcoins into the main wallet. Transaction monitoring, and all bitcoin are public, lets you see how the gigantic amounts of cybercriminals gain access.

“We are seeing some of these portfolios and we see millions of bitcoins worth millions. Looking at such huge untaxed amounts, I wonder if there are any cybercriminal unicorns, “says Mikko Hyppönen, F-Secure Research Director.

Unicorn is a term used in economics, which means a private technology company valued at more than one billion dollars, Uber, AirBNB or Spotify. For cybergangs the logic of action is similar, but there are differences such as lack of investors, administration and supervision.

Illegal business is profitable enough that some gangs provide customer service comparable to that of start-ups: cyberbots have their own site, FAQs, and even consultants.

Cybergang business model

Can the cyber-business model be compared to start-ups? Probably not. It is difficult to imagine selling cyber criminal business and finding investors. This would not be a problem in a Uber-like start-up, after which the queue is set up. Gangas ransomware, however, have to constantly look for ways to exchange earned bitcoins into cash.

“Hackers buy prepaid cards and sell them for example on Ebay,” says Mikko Hyppönen. Many gangs feast money in online casinos, but it is more complicated. Even if two gang members set up a game between them so that one of them loses all the money, then when the big sums count, the casino may consider acting suspicious and blocking the payout. That’s why gangs have started to use bots that play realistically, but they still lose – though not so clearly “- adds Mikko Hyppönen.

Prosecution of criminals

Law enforcement agencies are aware of the temptation of earning ransomware. Only in 2015, the FBI’s Internet Crime Complaint Center received “2,243 ransomware fraud complaints with a loss of more than $ 1.6 million”.

One example may be a loud attack on a Presbyterian medical center in Hollywood, which to recover their files paid a 40 bucks worth of ransoms worth $ 17,000.

“Officially, the FBI does not advise whether to pay a ransom or not,” said Sean Sullivan, F-Secure’s security advisor. “If the victims did not take proper precautions, then in many cases paying the ransom seems the only alternative to recovering files.”

Change location after order has been sent

Uber has finally launched a long awaited feature. From now on, passengers will be able to change their destination by the driver after ordering the course. Thanks to this, company employees will avoid problems with finding a passenger.

Uber offers much more convenience in terms of service compared to taxis, but on some issues they are much worse. Of course it is to change the seat of the passenger after ordering the course.

Sometimes it may turn out that in the place we have chosen, the lighthouse is not lit or in the vicinity of the place of stopping, a flower of the local youth enjoying a cheap drink. In short, a particular place may not be safe, so the passenger is away, and then the driver can not find him, losing money because of such situations.

Uber then introduces a new feature that is available in the US, Canada and the United Kingdom for the time being, and allows you to change the destination after ordering the course. All you need to do is to click on the icon in the app to mark the place where you can pick up your passenger so that you can edit it.

The driver will then receive a notification and will be automatically redirected to a new location.

Less educated people are more likely to die in accidents

One might think that the number of fatal car accidents should not have anything to do with the level of driver education. Meanwhile, American researchers have found such dependency, and the latest report shows that people with poor education are more likely to die in accidents than drivers with college diplomas.

In general, the number of fatal road accidents in the United States is decreasing year by year. It turns out, however, that there is a certain social group in which the number of fatalities is rising, and these are poorly educated people. Sam Harper, Thomas J. Charters and Erin C. Strumpf, who published their findings in the American Journal of Emidemiology, have the same opinion.

It follows that the increase in fatalities in car accidents occurs in people aged 25 years or more whose education has stopped at secondary level.

This does not mean, however, that graduates are better drivers. These are rather economic issues. Slightly more educated drivers earn much less so they can only afford much worse cars, lacking many of the safety systems present in new models such as side airbags, rear cameras, collision warning systems, What’s more, poorer neighborhoods are also of poorer quality, with less stop signs, pedestrian bridges and release slots, so the accident is more likely, but more often the pedestrians fall victim to collisions.
