Police radar lets you look through the walls

The American police will soon be able to further violate the privacy of citizens. The local law enforcement agencies are equipped with new, very modern radar systems. The device is called Range-R and allows you to physically peek into the house, looking through the walls.

In situations where criminals take hostages, it is very important to get an image from the inside of the building to see the location of terrorists and hostages themselves. This makes it easier for anti-terrorist units to accurately plan the assault, including choosing the most appropriate time to attack.

It is often used for endoscopic microscope cameras, but soon it will not be necessary, as the uniformed services will be able to openly use the new technology to look through the walls. This is the new Range-R radars, which the US police quietly has been using for more than two years.

The system is used by more than 50 US government agencies including FBI agents and the Marshals Service. Devices, each costing 6,000 dollars, at a distance of more than 15 meters allow you to see what is going on at home and whether, for example, no one is hidden in it. Technology allows you to see through walls as it feels so sensitive that it easily detects motion and even breath and lets you determine the exact location of your target.

The disclosure that the uniformed services use the Range-R, which took place in December last year during one of the court proceedings, caused a lot of buzz in the American media. Especially from organizations defending the right to privacy, which, according to radars, may violate it. Although the Supreme Court stated that uniformed people have no right to use the equipment if they do not have a search warrant, no one can guarantee that the warrant is obeyed.

Christopher Soghoian of the American Civil Liberties Union says technology that allows police to see homes is one of the most invasive tools in her arsenal.

L-3 Communications, a manufacturer of Range-R radars, has confirmed that it has sold about 50 such devices. The Marshals Service purchased radars in 2012 and has spent $ 180,000 on it, so it’s easy to calculate that it has 30 such devices.

It is worth emphasizing that the Range-R is one of the less advanced devices of this type, as there are already much better models that can present people’s position in three dimensions. The Department of Justice, on the other hand, is working on a system that can create a map of the interior and locate all the people in it.

Lost memories can be recovered

Recent research by researchers at the University of Notre Dame has allowed us to uncover more amazing features of the human brain. It turns out that he can recover the previously lost memories.

Our brain is like a big computer capable of storing huge amounts of data. This concerns memories from all of our lives. Some of them must of course be erased in order to make room for new ones, but occasionally the memories disappear as a result of illness, Alzheimer’s.

A team of neuroscientists from the University of Notre Dame, working under the direction of Nathan Rose, however, discovered that the lost memories could be restored. The scientist says that it is enough to just treat the brain with a small amount of electricity and this allows them to access them. This is possible because our memories are not really forgotten at all, but the processes that take place in the brain can make us think that way.

Studies in the Science journal also show that our short-term memory has more layers and is more dynamic than previously thought. Understanding how it works can lead to a better understanding of human cognitive abilities.

Great sales results

Tesla reported the latest sales figures for its car, covering the first quarter of this year. It follows that Model X is increasingly popular with customers.

Model S has enjoyed the most success among Tesla customers. Recently, fans of this brand are increasingly interested in its first SUV, Model X. The latest sales data for the first quarter of this year shows that sales of this car are beginning to approach the sales of the Model S.

Since the beginning of this year, customers have purchased 11,550 models of Model X. For comparison, Model S has sold 13,450 units, so as you can see, the difference is only 1900 vehicles. In 2017, the SUV sells much better, because in the same period last year these proportions looked quite different. Model S sold 12,400 units, while Model X only 2,400 units.

The interest in the SUV is so great that Tesla does not keep up with their production, and for the first two months of this year, there were problems with the availability of this car. This shows that electric cars are gaining market power.

New Midi Tower housing

Sharkoon, a well-known manufacturer of high-end computer rebuilds, is launching its latest model, the BW9000. It is a standard Midi Tower enclosure, whose modern design is very elegant and the functionality is very high.

Computer users often do not realize how important the whole package is to the enclosure. It is a framework of the whole system, which decides the comfort of installation of components, provides adequate cooling, etc. Most consumers buy the cheapest housing, while it is worth buying a little more expensive not only to present the computer nicely, but also to avoid many problems.

The BW9000 is the latest Sharkoon casing model, which has just appeared on sale at an attractive price of 67.90 euros. This is a Midi Tower enclosure designed specifically for liquid cooling kits, high performance processor coolers, and long graphics cards.

It also features easy-to-access dust filters that prevent component contamination, as well as tool-less system installation. The housing is available in two variants: plain and with a window through which you can look inside.

Its manufacturer has undoubtedly put a lot of emphasis on efficient cooling of components, installing a large number of windmills in the middle. As standard, it features two 140mm front-mounted fans and a 120mm rear panel that lights up with LEDs in the window version. The purchaser may additionally install three further 120 mm fans on the upper panel or two 140 mm.

You may also opt for water cooling if you plan to insert strong components into the enclosure. The manufacturer has predicted a place for two radiators. The first of them is 280 mm or 360 mm and 5.5 cm windmill can be installed in the top panel, while in the front will be a 280 mm cooler with a 6.5 cm high windmill.

The maximum length of the power supply may be 26 cm. The graphics card installed can be up to 43 cm in length, while the processor cooling fan can have a maximum height of 16.5 cm.

The manufacturer also installed three dust filters on the top, bottom, and front panel, with easy access for replacement or cleaning. Thanks to them, the interior of the enclosure will remain quiet for a long time.

Ebooks are similar to paper books

While digital books are much more convenient than paper, because they occupy less space, and offer easier searching for chapters, standard books have an edge over them in several respects. Amazon decided to suppress it by introducing Page Flip.

Digital books will not push the paper market for a long time, though they certainly have many advantages. We will fit the entire library on the size of the postage stamp, we do not have to fear the degradation of printing with age, and we have fast access to individual chapters.

Paper books also have some other advantages that we will not find in digital versions, but the latter are slowly beginning to catch on. Amazon has just released a new feature called Page Flip that has been introduced to Kindle readers, as well as Kindle applications available on iOS and Android platforms.

This is the equivalent of inserting a finger into a book, creating a bookmark, and then quickly looking through the remaining pages for interesting snippets or pictures. Once activated, the read page will be placed in a small window, while on the rest of the screen, you will be able to see thumbnails of the other pages, with the ability to zoom in on each of them. Then you can return to the read page.

Google hits the usury industry

In just a few weeks, online advertising of usurious loans will be much more difficult. Google has decided to block ads displayed on the search engine for this type of service. The company has announced that the blockade deals with companies offering short-term loans at high interest rates.

Sometimes it happens that we do not have enough for our next paycheck and we need to rescue a loan that will allow us to survive. Difficult situation is very willing to use then all kinds of loan companies, offering money for short terms for huge interest rates of up to several thousand percent per year.

The most common form of customer acquisition by such companies is online advertising, and many of them buy out Google search ads, thus reaching millions of customers around the world.

Soon, however, such a form of service promotion will become impossible. Mountain View Company has announced that it will block ads from companies that provide loans for up to 60 days from June 13th around the world. In addition, businesses in the United States will be blocked from paying an annual interest rate of more than 36 percent on loans.

David Graff, director of product policy at Google, wrote on the company’s official blog that Google is trying to protect its users, as such loans use human weaknesses and can put them in serious trouble.

Jawbone ends with consumer electronics

Jawbone announced that it is ending with consumer electronics. The company has announced that it will only deal with medical products from now on.

An example of Fitbit, which due to weak financial results has to slow down some staff shows that the market of fitness straps is in worse condition. For this reason, Jawbone, a company well known for producing such devices, announced that it is ending with consumer electronics.

The company has issued a statement in which it confirms the departure from the design of the wearable devices and intends to focus on products and services for the medical market, ie equipment for clinics and clinics for treating patients.

The decision was dictated by the small profitability of the current business. Jawbone has received $ 951 million from investors for the development of wearable equipment and although it has spent nearly half of that amount, it has only paid a small share of the invested funds.

Amazon headphones with life saving technology

Amazon has patented modern headphones that can theoretically save lives. The noise reduction technology installed in them is equipped with a music off mechanism when a certain type of sound is emitted at a selected frequency.

Built-in noise canceling technology is very useful as it eliminates background noise, allowing you to focus entirely on the music. Unfortunately, it is also dangerous because the user does not hear the ambient sounds. Maybe then fall under the car when riding a bike or not hear the person calling for help.

Amazon has patented a solution that can potentially save lives. The company patented a technology that automatically turns off the music when built-in microphones detect the sound of a certain frequency. It may be a scream, or even a specific phrase, eg a name. The headset at this point will immediately hear what’s going on around him and he will be able to respond to the situation right away.

Toshiba starts vegetable farming

Big electronics companies are increasingly getting involved in fruit and vegetable production. This may sound weird, but our planet is becoming more populated and needs new ways of producing food that will not only be effective but will also provide healthy food for our body. Toshiba is one such company that is starting to enter a completely new market sector for her.

Speaking to Toshiba, we mean primarily laptops and consumer electronics. However, these are not the only areas of activity of this concern, which is beginning to be interested in agriculture.

Media reports that the Japanese giant recently launched a new laboratory in the Yokosuki industrial district, where under sterile conditions, under fluorescent lamps, vegetables are grown. As a result of this experiment, a very clean lettuce is created, which does not need to be washed before eating, which is an indispensable activity for typical vegetables purchased at a local shop.

The whole process is quite unusual for a vegetable farm, because all employees wear protective aprons and must wash their hands with alkaline water before entering the farm. The farm itself does not resemble a regular field as all environmental conditions are controlled by computers. Air pressure, temperature, lighting level, dust and bacteria are all controlled by electronics and software. As a result of these activities, plants are created that are not attacked by bacteria, do not need to be sprayed with pesticides and washed before eating.

Toshiba plans to use its idea on a much wider scale and intends to sell such systems to Russia and countries in the Middle East where conditions are not conducive to typical vegetable farming. Sam will also be in production and plans to deliver at least 3 million heads of lettuce on the Japanese market each year, hoping that the new venture will bring additional profits to the Japanese market.

The new ultra-fast camera will help detect cancer

A camera developed by scientists at the Massachusetts Institute of Technology under the direction of prof. Ramesha Raskara has enough speed to film a laser beam striking an object and its reflection. The researchers recorded very fast flashes of the laser, lasting 50 femtoseconds (femtosecond is one billionth of a second – PAP).

The fastest scientific cameras currently record images at a million frames per second. They work the same way as cameras sold on the consumer market – the main part is a CMOS converter that converts optical light into a digital form that can already be written to disk. The fastest camera developed by a team of researchers at the University of California operated at 6.1 frames per second and its shutter speed was 163 nanoseconds.

The MIT scientist’s camera is built differently. As a technology reviewer, Dr. Andreas Velten, a member of the engineering team, said that the response time was limited to 500 picoseconds in the camera system so that the electrical signal did not stay too long in the wires and chips themselves. The shutter speed is less than two picoseconds (the picosecond is the trillionth of a second) because the prototype was designed to “catch” the laser beam. For this reason, this camera also did not need special electronics.

The light coming into its optical part went to a special electrode – a photocathode – converting the photon stream into an equivalent electron beam. The electron beam was in turn on the back of the camera, covered with a chemical that glowed under its influence. This is almost exactly the same mechanism used in the recently produced cathode ray tubes of classic TVs.

Due to the fact that the camera was able to see only one line, MIT researchers have built a mirror system that allows full illumination and viewing of the entire image. The construction is also completed with a classic digital camera, which records the image at the back of the camera. These two records are submitted by the software in real time and form a homogeneous image, while the digital camera record only covers a small portion of the laser beam path, which is completely visible to the fast camera. The image resolution of the first prototype device is 500×600 dpi.

MIT’s built-in camera does not capture events that do not happen quickly and on a regular basis. This is a significant limitation in its application, however, Dr. Velten notes that its advantage, in turn, is the possibility of observing the previously impossible to grasp the moment of penetration and reflection of light in the plane or tissue.
