Security robot with net

02.05.2009

An experimental security robot, made by two Japanese firms, travels around the premises left under its protection at a speed of up to 2,7 meters per second and, having noticed or heard something suspicious, reports it to its owner by cell phone.

On the screen of the phone, you can see what the robot sees, and by pressing the keys you can control its actions. If necessary, the robot is able to detain an intruder who has entered the house by throwing a network of thin, but very strong threads on him. And then the owners will come in time.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

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 ... >>

New uninterruptible power supplies Schneider Electric 10.03.2015

The IT Business division of Schneider Electric, a global expert in energy management and industrial automation, is updating the BX line of the APC Back-UPS family. The discontinued BX650CI, BX800CI and BX1100CI models will be replaced by Back-UPS BX700UI, BX950UI and BX1400UI line-interactive uninterruptible power supplies, equipped with computer outlets and built-in voltage regulators. These UPSs are more resistant to power outages and differ from their predecessors in the presence of a USB port for communication with a computer.

The BX700UI, BX950UI, and BX1400UI Back-UPS are line-interactive and generate 230V. All units have low battery transfer thresholds and are able to withstand extended mains input voltage drops without switching to battery backup . The total power of the new models is 700VA/390W, 950VA/480W and 1400VA/700W.

According to Schneider Electric, the novelties are able to automatically stabilize the voltage in the range of 140-300 V (BX700UI) and 150-280 V (BX950UI and BX1400UI) to a safe level, which allows the electronics connected to them to operate continuously at low and high voltage in household electrical networks. Thanks to the presence of the RJ-11 connector, it is possible to protect equipment connected to the telephone network, such as an expensive telephone, fax or DSL modem. Monitoring the status of the UPS is easy thanks to the presence of audible alerts and LED indication.

The Back-UPS BX700UI, BX950UI, and BX1400UI connect to a computer using a USB port. Users can download APC PowerChute Personal Edition software for free, which allows you to monitor key UPS parameters, change source settings, and calculate the battery life of connected devices based on battery level. In the event of an extended power outage, APC PowerChute automatically initiates a data save and shutdown procedure for the PC.
