Economical street lamps with new LEDs

German scientists from the Karlsruhe Institute of Technology have developed a new type of LED. They consume less energy, produce less heat and are softer on the eyes, so they are great for street lamps.

A few years ago began the process of modernizing street lamps lighting our cities at night. So far used sodium lamps have replaced LEDs that give brighter light and consume less energy.

Unfortunately, they also have a lot of flaws. LEDs require effective cooling to prevent damage, and in addition they give very sharp light, which not everyone responds. Besides, the way of connecting the diodes makes that if one of them refuses to obey, then the whole lamp is for replacement. Not to mention that they require a higher voltage (120 V), and up to a maximum of 40 LEDs in such a lamp.

However, scientists from the German Institute of Technology Karlsruhe (KIT) have created completely new modules of diodes, which consume significantly less energy, are better for the eyes and much cooler and thus safer.

Engineers from KIT have developed a new method of connecting the diodes, thanks to which one blow will allow the lamp to continue to function. In this way, the number of LEDs in a single lamp can be as high as 144, with a minimum voltage of 20 volts for operation. Low voltage LEDs are also much cheaper, so even though there are more lamps in the lamp, the price should not change much. Relative to the standard.

Scientists have also succeeded in developing a cheaper and more efficient method of heat dissipation from LEDs, which extends their service life.

Gratz Luminance has expressed interest in the new technology, and the first products that use it will be available later this year.…

Laser weapons for fighters

In a few years, modern combat fighters will get even more powerful weapons in the form of lasers. They are working on the Northop Grumman armaments division, which commissioned the construction of such a system for AFRL (Air Force Development Laboratories). Military engineers will build a laser control system that AFRL is working on under the Advanced Technology Demonstration program.

The system is compact enough to be easily attached to an airplane. Then he will act as a defensive weapon, protecting the machine from rockets, drones and enemy planes.

The control system that AFRL engineers work on is not only aimed at tracking and tracking targets, but also monitoring the weather conditions so that no interference does not affect the effectiveness of the weapon. The beam of light may be weakened by air pollution, fog, or dense. rain.

The first tests of a new laser weapon are scheduled for 2019.…

Entertainment incentives to throw out trash

Urban-X’s New York startup has unveiled an unusual trash can. The project called TetraBIN was created to encourage the hybrids of the city to throw waste away where they should be instead of leaving them on the street.

The problem of dirty streets is all over the world, because many of the city’s residents are reluctant to look for a nearby trash to get rid of the waste, leaving them where they are. Urban-X’s New York startup has created a special basket designed to encourage the dumping of garbage.

TetraBIN has a built-in LED display on which to play. There are bats flying in the virtual sky, while the dogs have to be fed on the ground. The three-chambered interior of the trash was filled with motion sensors that detect any dumped trash.

The waste that is inside it is then translated into the digital equivalent of chicken legs thrown by hungry animals. Feeding the belt is rewarded with special codes that can then be used on the TetraBIN website, exchanging it for physical items.…

Autonomous technology also for older cars

In the next few years, the saloon will feature first models of fully autonomous cars that will no longer need the driver and pick up the passengers themselves to their destination. This does not mean, however, that older car models will become worse because they will also be equipped with similar technology.

Nauto is an American startup specializing in the design of auto- motive technology. The purpose of the company’s activities is to develop solutions that would also equip older vehicles with such systems, thereby increasing their functionality.

The first step in accomplishing this task is a new device that monitors the surroundings of the vehicle by means of cameras, as well as records the driver’s face, keeping track of his eyeballs. The system will not be able to drive the car for the time being, but it will primarily be used to collect data for later use in more advanced devices.

Nauto has just started public testing of its new technology, which runs in San Francisco, with dozens of cabs and a fleet of private passenger cars. Data collected during the tests will be used to design new equipment, but the company also wants to make it available to the government that runs a program to reduce the number of road fatalities.…

Facebook Messenger will serve us advertising

David Marcus, Vice President of Product Product, confirms that Messenger Messenger will soon be popping up ads. They will appear as sponsored posts.

Most of Facebook’s revenue comes from ads, so the portal is looking for new ways to deliver to their users. One of the latest ideas is to provide sponsored posts to people using the popular messenger messenger.

This plan was during David Marcus, vice president of product portal, who appeared at the Lisbon Web Summit conference. He explained that advertisers would now be able to provide users with posts promoting their products.

However, he assured that Facebook will keep full control of the system so that users are not accidentally overwhelmed by spam. For example, an entrepreneur will not be able to send sponsored posts to a person who does not have an open conversation. Theoretically, this means that the user does not get ads from a company that he had nothing to do with him yet, although knowing life is not that certain.

Fortunately, if it turned out to be otherwise, then the user would be able to block such messages if they did not want to receive them.…

Here is the smallest notebook for gamers

Can an 11-inch laptop be suitable for computer games? Apparently, Alienware thinks that’s the way it is. Therefore, at the CES 2010, the company announced the M11x.

It will be the first such device on the market. The manufacturer has managed to get the power of a standard 15-inch notebook, but in much smaller form factor. For now it is not known exactly what will be the exact specification of the computer. Something we already know.

The only known components are the 11.6-inch 720p screen and the NVIDIA GeForce GT 335M graphics card (most likely with 1GB of RAM) accompanied by an additional integrated processor. The device will be equipped with a battery to provide power for 2 hours of play or 6.5 hours of typical “everyday” work.

Alienware M11x is expected to hit the market this spring. Interestingly, it will not be as expensive as it may seem at first glance. Alienware ensures that the price does not exceed $ 1000.…

Intelligent health monitoring bandages

Researchers from Swansea University have just started testing innovative medical technology in the form of smart patches. Devices equipped with 5G connectivity will be checked for another 12 months.

Technological advances in medicine are so rapid that in just a few years doctors will be able to remotely monitor patients’ health by providing information on their vital parameters. This will help with smart slices, which will be tested soon after at Swansea University.

Scheduled for 12 months, it will assess the suitability of modern patches with microscopic sensors and 5G connectivity to monitor patient health. This will allow doctors to more accurately determine how to treat their injuries, taking into account parameters such as activity and location. If, for example, the sensor shows that the therapy produces the desired results and that the patient is physically active, the doctor will be able to use a different solution than those who need to remain at home and their injuries heal much more slowly.…

Enlarged reality removes aggression on the road?

A team of Dutch researchers from Eindhoven University of Technology has developed a mobile application that can reduce aggression on the road. The tool uses expanded reality to improve communication between drivers.

Driving is a very nervous business. Not all of them can lead, so they are traveling the road, enforcing precedence and doing many other mistakes that cause our rage. When this reaches its apogee, such situations can sometimes end up with a fight, which many examples will find, for example on YouTube.

Researchers from the Dutch University of Technology, Eindhoven, led by Chao Wang, have created something that can help in such situations by preventing road aggression. They have developed a special mobile application that uses enhanced reality technology to streamline communication between drivers.

An application called CarNote uses our smartphone camera to scan the road for specially designed stickers on the rear window of the car. This way, the identification of drivers and their placement in the system is performed.

The task of this tool is to inform other drivers of our intentions, as well as the ability to evaluate their driving style. If, for example, we rush to the hospital, instead of trumpeting and flashing lights on cars in front, we can send information to the previous vehicle to go to another belt. We can also express our disapproval of a driver who drives aggressively and puts others in danger, arriving the road and enforcing precedence. In the future, such data could also be used by insurance companies to make aggressive drivers increase their rates.…
