IR port for PC

The IrDA (Infra red Data Association) protocol allows you to connect to peripheral equipment without a cable using infrared radiation. The IrDA port allows communication over short distances in point-to-point mode. The IrDA interface uses a narrow infrared range (850-900 nm) with low power consumption, which allows you to create inexpensive equipment and does not require FCC (Federal Communications Commission) certification. The IrDA port is based on the PC COM port architecture, which uses a UART (Universal Asynchronous Receiver Transmitter) and operates at a baud rate of 2400-115200 bps, providing stable half-duplex communication.

The infrared port is connected directly to the motherboard, in most cases the pinout on the board corresponds to the diagram and is described in the documentation for the board, if the pins do not match, they can be easily rearranged. After installation, you need to enable infrared port support in the BIOS. ("Chipset Features Setup" ->UART2 Use Infrared" ->Enabled"). If the Windows 9X operating system is used, then it will install the drivers necessary for operation.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Temple air is dangerous to health 05.04.2005

An air pollution study conducted in two churches in Maastricht, Holland, showed that spending an hour in a temple, breathing candle smoke and church incense, is 20 times more harmful than standing on the side of an autobahn with heavy traffic for an hour.

The content of particles in the air with a size of 10 micrometers or less, penetrating deeply into the lungs, and from there into the blood, even before the start of the service, was 3-5 times higher than on the side of a busy highway. After nine hours of service, which is typical for Sundays, hazardous particles that cause emphysema, heart failure and cancer have exceeded the dangerous limit of one milligram per cubic meter of air set by European health standards.

In addition to soot particles, high levels of carcinogenic polycyclic aromatic hydrocarbons and free radicals were found in the air of temples.
