The book is addressed to the reader who has experience in designing electronic devices. But why is this? - a modern user will ask with bewilderment, - after all, everything can be bought. Far from everything - it is possible, and even less so - it should be. First of all, because many of the previous bans on self-defense did not disappear, but only changed form: from administrative they became “market”. So, an ionizing radiation sensor, inaccessible to the Soviet buyer, the so-called. Geiger counter (complexity - a neon light bulb), you can buy, but ... at the price of a TV. It is also important that "sales" security equipment refers to goods, payment for which is made immediately, and the real value is found out later. Millions of our fellow citizens could share their sad experience in acquisitions of this kind. But this “product” has a peculiarity: whoever buys it risks losing not only money. The book gives detailed descriptions of security equipment devices that can only be repeated, and advice to the designer who implements his own ideas. And comments and remarks to them can be interesting in and of themselves.
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 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. ... >>

Relatively recently, C3D announced the creation of a new type of storage media under the general name FMD ROM (fluorescent multilayer disk), that is, a fluorescent multilayer disk.
This promising development, as expected by its creators, should, after its release, replace all currently existing storage devices, not only outdated CD-ROMs, but also relatively new DVD-ROMs.
Magnetic disks have existed for more than thirty years, CD-ROMs for a little less than twenty, the CD has most recently been replaced by the DVD standard, and in less than three years, the successor to DVD has appeared. Yes, DVD, which is by far the most capacious removable media of digital information. And in the near future, it will yield in all respects to the new FMD ROM media standard.
