The table shows data based on the PUE, for selecting the cross sections of cable and wire products, as well as the rated and maximum possible currents of circuit breakers, for a single-phase household load most often used in everyday life

Cross-section of copper conductors of wires and cables, sq. mm	Permissible continuous load current for wires and cables, A	Maximum power of single-phase load at U=220 V, kW	Rated current of the circuit breaker, A	Limiting current of the circuit breaker, A	Characteristics of an approximate single-phase household load
1,5	19	4,1	10	16	lighting and signaling groups
2,5	27	5,9	16	25	socket groups and electric floors
4	38	8,3	25	32	water heaters and air conditioners
6	46	10,1	32	40	electric stoves and ovens
10	70	15,4	50	63	introductory supply lines

In each case, it is necessary to take into account the load power and the length of the power line

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Ladybugs - prototypes for rescue robots 17.04.2020

When a ladybug takes off, its wings open in one tenth of a second. This physiology makes these colorful little bugs an inspiration for flying robots. Scientists from the Robotics Research Center at Seoul National University in South Korea have been able to construct models similar to these insects.

The wings, developed by the university's ladybug prototype team, are strong in flight and can fold like origami as soon as the robot hits the ground. Such lightweight and compact technologies could make future versions of robots ideal candidates for search and rescue or reconnaissance missions.

The key to the insect's rapid takeoff is the unusual veins on its wings, with a slightly curved shape that allows them to store elastic energy when they are bent and then release it when the wings open. The curved veins also make the wings stiff during flight, similar to how a tape measure stays straight when stretched out.

A team of engineers was able to model 30 cm fabric wings with artificial plastic veins and attach them to robotic insects. Veins can open in 116 milliseconds, and such wings can carry 150 times their own weight.

One of the special advantages of the ladybug robot is that it can move its wings out of the way by folding them up. This allows him to jump or crawl when he is not in the air. The creators are planning to upgrade future generations of robots that will be controlled by artificial intelligence for more autonomous movement.
