Contains systematized information on the training course "Systems and means of security alarms". Much attention is paid to the development and operation of technical means of security alarms, the methodology of their creation and application as elements of technical systems for ensuring the integrated security of security objects. For university students, it may be useful for engineers specializing in the creation and operation of technical means and security alarm systems, as well as for managers and employees of the security (security) services of facilities.
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. ... >>

Seal in touch
13.12.2002
Unlike the hero of the "Telephone" Chukovsky, the staff of the University of St. Andrew (Scotland) are happy when another seal calls them. They glue miniature radio beacons provided by the German company Siemens to the fur of newborn seals.
The device, which works through the cellular telephony network, from time to time sends messages about the activity of the seal to the university computer. If there are no messages for several days, the animal is considered dead.
Of the approximately 38 gray seals born every November in colonies of these mammals on the coast of Britain, only half survive to their first birthday, but there is no exact data yet. In the future, scientists intend to add a depth gauge and a positioning device to a simple motion sensor in radio beacons in order to accurately record migration routes and the depth at which animals hunt.
The device stays on the skin of a seal for no more than a year and disappears during the next molt.
