Cars wink at the oncoming

14.08.2002

Drivers often flash their headlights at oncoming vehicles, warning, for example, of an ambush with a radar speed meter.

According to the German inventor Heinz Müller, modern xenon lamps in the headlights will allow much more meaningful information to be transmitted. The new lamps are gas-discharge and therefore have no inertia. Flashing at a frequency imperceptible to the eye, up to a billion times per second, they can transmit messages, for example, about traffic jams, about accidents, about areas with ice, and if necessary, about the technical condition of the car.

The perceived information will be played on a screen in front of the driver or read aloud by a speech synthesizer.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Room lock is opened by smartphone 29.01.2014

Starwood Hotels & Resorts Worldwide Inc. plans to install new locks by the end of the current quarter on all rooms at its two existing Aloft Hotels in Manhattan and Silicon Valley.

The hotel guest must install the Starwood application on their smartphone, which will manage the opening of the room's doors. The application is compatible with smartphones running Android version 4.3 and higher, as well as Apple devices starting with iPhone 4s, via Bluetooth.

While some have doubts about whether such technology will take root. Such opinions are based on the aspect that some people do not like such innovations or simply want to use the usual keys. One way or another, Starwood plans to equip all 123 hotels in the chain with similar locks by the end of next year. Pointing out that many of the chain's establishments actually belong to other owners, only using the Starwood brand, CEO Van Paaschen assured that investments for such an upgrade would be negligible, and Starwood itself would bear the bulk of the costs.

In addition, it was clarified that the locks run on their own batteries and do not depend on the hotel's computer system, and the staff of the institution receives automatic notifications when the battery is running out.
