7.2.14. The power supply of an entertainment enterprise with a total (with several auditoriums in one building) number of seats in auditoriums of 800 or more and children's entertainment enterprises, regardless of the number of seats, must meet the following requirements:

1. It is recommended to supply power to electrical receivers from two transformers of the customer’s own (subscriber) TP. If it is not practical to build your own transformer substations, the power supply for power receivers should be supplied from two transformers of the public transformer substation.

2. Transformers must receive power, as a rule, from two independent sources of 6-10 kV.

3. When one transformer is disconnected, the remaining transformer must provide power to all electrical receivers of the entertainment enterprise.

4. The main switchboard must have two sections of 380/220 V buses with ATS devices on the buses. The main switchboard sections should be powered from transformers by mutually redundant lines.

7.2.19. Complete transformer substations with transformers that do not have oil filling can be located inside the building in a separate room. At the same time, it must be possible to transport PTS equipment for replacement and repair.

7.2.20. Switchgear switchgear and rotating converters up to 1 kV for powering electric drives of stage mechanisms, cabinets with batteries and thyristor stage lighting controllers can be located in the premises of transformer substations and package transformer substations, subject to the condition that all electrical equipment located in the premises is serviced by facility personnel.

7.2.21. The switchgear of transformer substations above 1 kV must be located in a separate room with independent lockable entrances for maintenance by personnel of the energy supply organization.

Placing switchgear up to 1 kV and higher in one room is allowed only if they are operated by personnel of one organization.

The requirement to place switchgear up to 1 kV and higher in different rooms does not apply to package transformer substations. The high-voltage part of the package substation, if necessary, is sealed by the organization under whose jurisdiction it is located.

7.2.22. Connecting other electrical receivers to the lines supplying electro-acoustic and cinematographic devices is not allowed.

7.2.23. The power supply for safety and emergency lighting must be in accordance with the requirements of Sec. 6.1 and taking into account the additional requirements given in paragraphs. 7.2.24 and 7.2.25.

The installation of rechargeable batteries for these purposes must necessarily include:

1. In children's entertainment enterprises, regardless of the number of seats and the number of power sources.

2. In entertainment enterprises (except for cinemas) with a total number of seats in auditoriums of 800 or more, regardless of the number of power sources.

3. With one power supply:

in club establishments with a total number of seats in auditoriums of more than 500;
in other entertainment enterprises with a total number of seats in the auditoriums of more than 300.

If there are two power sources for the entertainment enterprises specified in paragraph 3, batteries may not be installed.

Batteries may also not be installed:

in cinemas with a total number of seats in the auditoriums of less than 800;
in club institutions with a total number of seats of 500 or less;
in other entertainment enterprises with the number of seats in the auditoriums being 300 or less.

7.2.25. Cabinets with portable batteries are allowed to be installed inside any premises, with the exception of premises for spectators and artists. Portable batteries with a voltage of up to 48 V and a capacity of up to 150 Ah for powering emergency lighting and fire alarms, installed in metal cabinets with natural exhaust ventilation to the outside of the building, can be charged on site. At the same time, the explosion and fire hazard class of the premises does not change.

The battery capacity should be selected based on the continuous operation of emergency lighting fixtures for 1 hour.

Acid battery installations with voltages higher than 48 V and a capacity of more than 150 Ah should be carried out in accordance with the requirements of Chapter. 4.4.

But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

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 ... >>

Cameras in a supermarket monitor shoppers to create targeted ads 09.08.2023

In the Japanese city of Hofu, Aruk Mitajiri paved the way for the future of retail by becoming the first store to use an innovative smart system to monitor the behavior of its customers and provide them with personalized advertising. This outstanding system was developed in collaboration with Fujitsu experts and scientists from Waseda University.

The core of the system is special cameras capable of tracking the actions of customers: stopping in front of storefronts, picking up goods, comparing different options. This data is fed into a generative artificial intelligence (AI) platform, which creates a personalized "assistant". This virtual advisor reaches out to visitors and offers products or services that best suit their interests.

The basis for the development of the system was the hypothesis that the purchase decision largely depends on the emotional reaction of the buyer to the seller, his perception of competence and level of understanding of the needs of the client, as well as the design and functionality of the product. Using the analysis of data and attributes of the buyer, the system evaluates the likelihood of a change in his behavior and provides recommendations based on this data.

Fujitsu emphasizes that this technology creates an immersive customer-centric experience that encourages customers to return to the store with a desire to purchase specific products that fully meet their interests and needs.
