open the radiator cap without sharply unscrewing it, being careful of a strong release of hot vapors (hands must be protected by gloves) and pour in coolant.

4.4. If it is necessary to eliminate a malfunction that has arisen during operation and carry out maintenance, the driver must turn off the engine of the machine.

4.5. If the cabin door is jammed, it is necessary to use the exit through the opened windows, if it is impossible to use it, squeeze out or break the glass and leave the cabin.

4.6. The operation of the unit should be stopped during heavy rain, during a thunderstorm, heavy snowfall, thick fog (visibility less than 50 m), at night, if the illumination of the working areas is less than the artificial lighting established by the norms (less than 10 lux).

4.7. The victim or eyewitness must notify the foreman or the appropriate work manager of each accident.

4.8. The driver must be able to provide first aid. Such assistance is provided immediately, directly at the scene and in the following sequence; first you need to eliminate the energy source of injury (turn off the engine, stop the saw mechanism, remove the victim from under the whip, tractor, etc.). Assistance should begin with the most significant that threatens the health or life of a person (in case of severe bleeding, apply a tourniquet, and then bandage the wound, if a closed fracture is suspected, apply a splint; in case of open fractures, first bandage the wound and then apply a splint; in case of burns, apply a dry bandage; in case of frostbite, gently rub the affected area using soft or fluffy tissues).

If spinal injury is suspected, transport the victim only in the supine position on a rigid base.

4.9. After providing first aid, the victim should be sent to the nearest medical facility.

5. Safety requirements at the end of work

5.1. The driver must:

place the DO-36 unit in the place designated for parking and lower the jaws to the ground;
check the neutral position of the loader and process equipment control handles;
turn off the hydraulic pumps, stop the engine, disconnect the battery, close the cab door with a lock;
clean the car from dirt and branches;
when parking in cold weather, it is necessary to drain the water from the radiator and engine cooling system, remove the battery;
make an external inspection of the unit and its attachments;
if malfunctions are found and it is impossible to eliminate them on their own, report to the mechanic or foreman.

Artificial leather for touch emulation 15.04.2024

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 ... >>

The attractiveness of caring men 14.04.2024

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. ... >>

S2-LP - 433/868 MHz narrowband transceiver 11.03.2017

S2-LP is a new 433/868 MHz transceiver from STMicroelectronics, designed to create cost-sensitive IoT devices, but at the same time with high requirements for radio communication quality and consumption.

To what extent this was done can be assessed by looking at the impressive technical characteristics of the new microcircuit. The receiver sensitivity starts from -130 dBm, while the developer can work with a path bandwidth from one kilohertz. The output power is adjustable over a wide range - from -30 dBm to +16 dBm in 1 dBm steps. Thanks to the new class E amplifier, the current consumption at 10mW output power is only 10mA, while in receive mode the consumption is within 7mA. The microcircuit is the best in its class in terms of consumption in transmit mode.

Reducing the current draw of internal RF components often leads to reduced RF performance. However, the S2-LP transceiver performs well both in terms of link budget (> 140 dB RF link budget) and selectivity. Adjacent channel selectivity is 68 dB (@+-12.5 kHz), blocking is better than 80 dB at 2 MHz offset (@433 MHz)

The S2-LP transceiver can work with any external microcontroller. Control is performed in the most familiar way - via SPI with interrupts through customizable GPIO0 ... GPIO3 lines. To work with STM32 microcontrollers, there is a library and a set of examples for STM32Cube.

Features of the S2-LP transceiver:

Narrowband transceiver 430 - 470 / 860-940 MHz
Output power up to +-16 dBm; Sensitivity up to -130 dBm
Air data rate 0.3 - 500 kbps
Modulation types 2-FSK, 2-GFSK, 4-FSK, 4-GFSK, OOK, and ASK
Low consumption in active mode:
6,7mA RX
10mA TX @ +10dBm
Sleep Consumption 600nA (with timer)
Fast wakeup and fast synth setup time
Automatic retries and confirmations
Suitable for Wireless M-Bus systems; 802.15.4g
Case 4x4 mm QFN
Operating temperature -40...+85 °C
