The power supply provides stabilized voltage +12V, -12V and unstable +20V. Measures R1, C4, C5 have been taken to minimize the ripple of the +12V source, since it is directly used in the sound generators of the simulators.

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 ... >>

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. ... >>

Life in nature changes the way the body works 19.11.2015

Researchers have long noticed that living outdoors reduces the incidence of cardiovascular and respiratory diseases, diabetes, obesity, depression, and even cancer. But how it works, what exactly changes in the body is unclear.

Ming Kuo, a researcher at the University of Illinois, tried to figure this out. She studied many literature sources and found twenty-one possible reasons for improving health in nature. Moreover, only two of them had a common feature - the activation of the immune system.

"This means that the influence is complex: several factors act simultaneously, complementing each other," says Ming Kuo. But what provokes the action of factors? According to the author of the hypothesis, the reason is psychological. In nature, a city dweller feels relaxed, more secure than in a city where he constantly has to fight with his own kind and with circumstances. As a result, a different mode of operation of the body is switched on. In the city, all its resources are redirected to the fight, and there is no strength left for anything else. In nature, the body goes into the mode of rest and accumulation, resources are spent more economically.

Thus, no inhalation of phytoncides and visits to the solarium will replace a full-fledged country vacation.
