Americans are testing an autonomous helicopter

The American army apparently binds its future with unmanned machinery. For now they are drones, but in the near future will also be autonomous helicopters.

A few days ago there was a demonstration of the possibility of the specially modified JUH-60A Black Hawk helicopter, which is the forerunner of a new type of machine, requiring no pilots to fly, land and avoid danger.

This helicopter was equipped with the RASCAL (Aircraft Concepts Airborne Laboratory) RASCAL system, and its test was conducted over the Diablo Mountain Range, located near the California city of San Jose. During the presentation the pilots were present in the helicopter cockpit, but only as a security if the computers refused to obey. All the maneuvers, while the two hour flight at 60-130 meters, performed fully automatically and managed to achieve the target of 60 cm.

RASCAL enables the machine to navigate between obstacles, as well as the use of a terrain detection system, risk assessment, risk avoidance, and all this is done in real time.

The Army has not yet set a date for launching unmanned helicopters, but considering how advanced it will be, it will probably take place in the next few years.…

Jaguar XE the safest car in the class (according to Euro NCAP) among others. Thanks to active security systems

Active safety systems installed in the Jaguar XE have significantly contributed to its victory in the class: a large family car. Apart from the class names, this is undoubtedly the success of this brand considering how strong XE competition is. We have decided to take a closer look at what the active prevention of road events has to offer this car.

The Jaguar XE has undoubtedly hit the premium car market, competing with the Audi A4, the C-Class, the BMW 3-Series and the Lexus IS. The company decided to build a completely new ultralight platform, which uses high-strength steel as well as aluminum. Only after the first kilometers of the XE can be found how compact and rigid is the construction. This affects not only the ride characteristics that are just great, but also the safety. And the latter is backed up by active systems that take care to minimize the effects, and best to eliminate the risk of a possible collision. These are adaptive headlamps, blind spot monitoring, lane assistant, road marking, and transverse motion warning when driving back from the parking lot.

The blind spot monitoring system works similarly to other such solutions. He warns with a clear icon in the proper mirror of another vehicle next to our Jaguar XE. If we had decided to change the lane to include a turn signal, then this system would issue another warning flashing the icon. The effect is shown in the film below.

Another important element is undoubtedly the lane assistant, who warns against the vibration of the steering wheel unintentionally changing direction (crossing the line separating the straps). But that’s not the end, because a very useful solution is the transverse movement warning system, which definitely helps when leaving the parking lot behind. The way it works and its effectiveness is really commendable!

The Jaguar XE is usually a rear-wheel drive vehicle. We usually write because there are 4-wheel drive versions available. It is important, however, that with the JaguarDrive Control, the driver can choose from a sporty, normal, economical, slippery ride. It changes the characteristics of the engine, as well as the stability of the driving circuit. Particularly helpful is the latter mode, which significantly improves the performance of starting on slippery surfaces, such as on an icy road or wet grass.

The optional Jaguar XE is also equipped with a HUD display, so you do not have to tear your eyes off the road for navigation or current speed. This is useful not only during dynamic driving, but primarily because of safety.


The Jaguar XE is undoubtedly a unique car. It looks insane, as evidenced by the jealous looks of most pedestrians, and above all other drivers. It turns out that XE has more to offer than just amazing design, great traction, …

Lenovo is preparing another yoga tablet model?

Lenovo intends to enlarge the family of yoga tablets another model. The device, which is going through the approval phase of the FCC, will likely be equipped with a 10-inch touch screen and will also run on the Android platform.

The Chinese company Lenovo manufactures two types of equipment under the Yoga brand. The first is a Windows-based notebook, which can also be used as a tablet by the rotating screen, while the other is a typical tablet with a cradle and a wireless keyboard.

If you believe the reports from the Federal Communications Commission, Lenovo is preparing another Lenovo product that will be a typical tablet. The list includes a cover for a wireless bluetooth keyboard for a device called Yoga 2 10. As Yoga notebooks have a built-in keyboard, so the cover they do not need, so many point out that the next tablet is on Android.…

Xstat saved his first life

Last year we had the opportunity to familiarize ourselves with a new device called Xstat, designed for rapid gunshot wound closure, which seals the inlet, stabilizing the patient and protecting it from bleeding. The invention has already proved its usefulness, saving the patient’s life.

One of the greatest threats to human life is gunshot wounds. The ball hole can lead to bleeding, so it must be clamped as quickly as possible so that the patient is stabilized and can safely hit the operating table.

Such wounds are particularly dangerous in combat conditions, which is why scientists have been working for years on an effective way to temporarily close them. Last year a very promising invention called Xstat was created, which is able to close the gunshot wound in just 20 seconds, giving the patient more time to reach the hospital. The idea is not particularly complicated, as it is a large syringe filled with small sponges. The device pushes into the wound and pushes the plunger, inserting sponges that soaked in blood, seal the inlet.

Many were skeptical of Xstat and doubted its effectiveness. However, this was confirmed by a surgical team from one of the US hospitals who used a device to cushion hemorrhage in one of the patients during surgery. During the 7-hour procedure, the patient began to bleed heavily, and the current method of stopping hemorrhage was ineffective, so it was decided to use Xstat, which he did almost immediately, helping to stabilize the patient.…
