You can download other books, magazines, manuals, as well as diagrams and service manuals in our Free online technical library.
This reference manual presents materials on industrial designs of electronic and mechanical devices of domestic and foreign production, designed to protect cars. The main technical characteristics of modern systems are given, as well as the schemes for connecting them to the elements of the car. Provides easy-to-understand information about safety navigation and vehicle search systems that use advanced Global Positioning Systems (GPS) technology. Original circuit solutions for car security devices are proposed, their operation logic and principle of operation are described. Printed circuit boards and recommendations for installation and configuration given in the book will facilitate self-repetition of security devices. The book is intended for a wide range of car and radio amateurs who want to provide reliable protection for their car. It is of interest to specialists involved in ensuring the protection of cars of various brands.
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. ... >>

Microbes identify toxins
29.05.2012
Scientists from Tel Aviv University have developed a toxin sensor based on genetically modified bacteria. A small sensor called the Dip Chip is designed to warn the user of general toxicity, that is, it "tells" the presence of any toxic materials that are dangerous to a living organism.
Artificial toxins easily contaminate food and drinking water. In ancient times, human tasters were used to detect poisoned food. Today, there are more humane methods, including, for example, special fish that monitor the safety of drinking water, or special biosensors. But despite advances in toxin detection, modern electronic equipment is too complicated to use, expensive, rather bulky, and usually narrowly functional.
The Dip Chip contains microbes that react biologically to various toxic chemicals, mimicking the biological responses of humans and animals. The device was created on the basis of genetically modified microorganisms developed in the laboratory of Professor Belkin. When modified microbes are exposed to toxic or poisonous substances, they produce measurable biochemical reactions that are converted into electrical signals.
The Dip Chip Detector is very easy to use as it gives only two types of signals: "toxic" or "non-toxic". At the same time, the number of false positives, according to the developers, is very small. The main advantage of the Dip Chip is its ability to define toxicity as a biological quality. In other words, microbes determine the danger of a sample for the life of a living organism, and do not detect specific toxic substances (possibly not dangerous in small concentrations), as all other sensors do. Many excellent detectors already exist for identifying specific toxic substances, but quickly determining whether water is drinkable, for example, is much easier with devices like the Dip Chip.
Currently, Israeli scientists are working on improving their invention. They are going to create compact versions of the Dip Chip, suitable for installation in mobile phones and tablet computers, which will be useful to the military and tourists. Such electronics, equipped with a Dip Chip, can quickly determine whether a particular product can be eaten.
