Lakotkan electrical insulating in terms of heat resistance it corresponds to class A. Grades are used LHB (thickness 0,15; 0,17; 0,2; 0,24; 0,3 mm), LShM (0,08; 0,1; 0,12; 0,15 mm), LSMS (0,04; 0,05; 0,06; 0,1 mm), Paintwork (0,1; 0,12; 0,15 mm), LKMS (0,1; 0,12; 0,15 mm).

The letters on the stamps represent:

Л - varnished cloth;
X - cotton;
Ш - silk;
К - capron;
М - based on oil varnish;
Б - based on bitumen-oil varnish;
С - special, with increased dielectric properties.

Breakdown voltage of varnished cloth to inflection 0,04 mm - 400 V, 0,05 mm - 1200 V, from 0,06 to 0,24 mm - 3,9 kV. After the kink, the breakdown voltage decreases by 1,5-2 times. Guaranteed shelf life 6 months.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Humane AI Pin Projector 08.01.2024

Humane, founded by former Apple engineers Imran Choudhry and Bethany Bongiorno, is introducing its latest creation, the AI Pin wearable device.

The new AI Pin gadget from Humane is another step forward in the development of wearable technology, opening up new horizons in the field of artificial intelligence. With its unique features, ease of use and futuristic design, it can become a key element in everyday life, combining convenience and technological advancement.

The AI Pin is a compact, square device that attaches to clothing and is equipped with OpenAI GPT-4 models and artificial intelligence from Microsoft. It requires a $24 monthly cellular subscription, which includes T-Mobile data coverage and access to artificial intelligence capabilities.

However, what makes AI Pin unique is its revolutionary "laser ink display" feature. This innovative technology allows a green monochrome user interface to be projected directly onto the user's palm at 720p resolution.

The new product provides the ability to interact with the device using gestures and voice commands, providing wide functionality such as photographing, translation and calorie recognition. Thanks to the Cosmos operating system, which automatically routes user requests to the appropriate tools, this screenless wearable device can function without the need to manually download programs.

The AI Pin is lightweight, weighing only 34 grams, plus an additional 20 grams for the battery booster. It features a 13-megapixel camera and a personal speaker that adjusts the volume for individual or group settings. The device also supports connection to headphones via Bluetooth.

The proposed device is designed with user convenience and intuitive accessibility in mind. The company's vision is to enable a futuristic and seamless integration of artificial intelligence into everyday life, possibly transforming the way we interact with technology.
