7.5.73. Converter units of cathode-beam installations connected to a power supply network with a voltage of up to 1 kV must have protection against breakdowns in the insulation of low voltage circuits and the electric network caused by induced charges in the primary windings of step-up transformers, as well as protection against short circuit in the secondary winding.

7.5.74. Electron-beam installations must be protected from hard and soft X-ray radiation, ensuring complete radiation safety, in which the radiation level at the workplace must not exceed the values ​​\uXNUMXb\uXNUMXballowed by the current regulatory documents for people who do not work with sources of ionizing radiation.

To protect against switching surges, converter units must be equipped with arresters installed on the higher voltage side.

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. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of ​​controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog ​​owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Semiconductor RSL10 single-chip system 25.02.2017

ON Semiconductor announced the release of the RSL10 single-chip system that supports Bluetooth LE 5. According to the manufacturer, the RSL10 has the lowest power consumption among all similar products. Applications for SoC ON Semiconductor RSL10 include wearable electronics and IoT devices, including physical activity monitors, smartwatches, and home appliances.

The manufacturer considers the possibility of power supply from voltage sources of 1,2 and 1,5 V to the advantages of the new SoC. The voltage required for operation in the range of 1,1-1,3 V is generated by built-in circuits, without requiring an external converter.

At the heart of the RSL10 is a dual-core ARM Cortex-M3 processor available for custom applications. It operates at frequencies up to 48 MHz. In addition, the SoC configuration includes a 32-bit DSP, the performance of which is sufficient, for example, to implement audio codecs.

The manufacturer offers a complete development platform, including a development board, software tools, documentation kit, and libraries of Bluetooth protocols and profiles. Samples of the RSL10 are currently available in the WLCSP version (area 5,5 mm2, 51 pins). Samples in 6x6mm 48-pin QFN packages should be available by the end of April.
