Security television (video surveillance systems, security video systems, video control systems, CCTV systems, etc.) is the most demanded and rapidly developing direction of security systems. At the same time, as practice shows, this is also a rather difficult area of knowledge to master. In the presentation of the material, I deliberately avoided the names of equipment types and manufacturing companies, and I tried to convey the material as intelligibly as possible - on my fingers. It will be easy to see that I did not dig too deeply - firstly, as far as I know myself, and secondly, as much as is necessary for your practical work.
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 ... >>
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 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. ... >>

Power plant in a button
01.02.2002
Engineers at Columbia University (USA) have created a prototype gas turbine power generator that can replace batteries in portable electronics.
The button-sized miniature power plant is made in a block of crystalline silicon using the same methods used to make microchips. The fuel is hydrogen. Hot steam, the product of its combustion, rotates a turbine with a diameter of four millimeters, developing two million revolutions per minute, and an electric generator is connected to the turbine. The power of the unit is 20 watts, it is quite enough to power a laptop computer, a cell phone or just a flashlight.
True, not every owner will like the fact that his device throws out a trickle of hot steam. Therefore, most likely, a miniature power plant will be mounted in a separate case the size of a deck of cards, and the current from there will be used to charge conventional batteries of a computer, telephone, or flashlight.
According to the creators, the commercial version will be ready by the end of this decade.
