Comments on the article

The IR automatic identification system recognizes "its own" by a special signal emitted by the owner's key fob generator.

Such a signal can be a "packet" containing a strictly defined number of very short infrared pulses - flashes. Factors hindering the information "hacking" of such a system are, in addition, the duration of each flash and the duration of the entire "packet". They are limited, as a rule, by rather rigid limits.

The key fob generator that generates such a packet-code and the corresponding receiving device are described below.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Smart pillow Nitetronic F1 17.09.2023

The Nitetronic F1 smart pillow, presented by the German startup Ninetronic, has gone on sale. This innovative pillow combines water cooling and white noise technology to create the perfect sleeping environment. Plus, a graphene pillowcase is available for winter nights to provide extra warmth.

The device is divided into two parts: water and air. Filling the water part is simple and does not require the use of special liquids. The antibacterial pill included in the kit ensures the purity of the water in the pillow throughout the year.

The air part can be adjusted to your liking by adjusting the height and softness of the pillow. Each side has unique characteristics: the air side is soft and bouncy, while the water side creates a feeling of light cooling and floating above the bed.

The manufacturer claims to have paid special attention to head and neck support to ensure optimal sleep comfort and prevent problems with stiffness in the morning.

In addition, in collaboration with Open AI, the pillow has a built-in white noise generator that offers unique sound combinations for a more restful sleep. This generator creates soothing sounds, such as water flow, heartbeat or nature sounds, to help you relax and fall asleep faster.

In case of cold nights, it is possible to purchase a graphene pillowcase, which will ensure uniform and rapid heating of the pillow, creating a feeling of warmth and comfort.

The Nitetronic F1 project is available to order on Kickstarter starting at $79. For an additional $20, you can purchase a graphene pillowcase warmer for complete comfort on cold days and nights.
