Garmin Smart Bike Headlight

06.05.2017

Garmin has unveiled the Varia UT800 Smart 800 lumens smart bike headlight, weighing just 130 grams. The device provides bright continuous light for an hour and a half trip. When connected to the Edge cycling computer, the intensity of the beam can be automatically adjusted depending on changing light conditions and the speed of the cyclist, Garmin told CNews.

The device will make your trip safer in any conditions: day and night, on bike paths in the city and country highways. Varia UT800 Smart illuminates exactly the area of ​​the route and with the intensity that is necessary for visibility, orientation and trouble-free movement in given ambient light conditions. In the case when the cyclist picks up speed, the headlight automatically "raises" the beam of light and thereby increases the field of view, the company noted.

In the daytime, the light of the headlight is visible at a distance of more than 1,6 km. Varia UT800 includes five levels of light intensity - high, medium and low, as well as flashing modes for day and night. At 800 lumens, the Varia UT800 will shine as brightly as possible so that the cyclist has time to spot obstacles at the highest speed. At low speeds, the headlight dims to conserve battery power. At high speed, the Varia UT800 Smart headlight can accompany the trip for 1,5 hours, at low speed, the device guarantees sufficient illumination for 6 hours.

"We're excited to add the Varia UT800 to our line of innovative Varia products that improve cyclist safety," said Dan Bartel, Garmin's vice president of worldwide user sales. With five different light modes, this headlight shines brighter and lasts longer, giving cyclists more confidence."

With the help of a bicycle mount, the device is easily mounted on the handlebars or fixed on the helmet. When connected to the Edge cycling computer, the range of possibilities of the Varia UT800 Smart expands: the user can automatically turn the headlight on and off, adjust the brightness of the light depending on external conditions, the time of sunrise or sunset, the speed of movement, as well as automatically manage the power to activate the mode if necessary. energy saving.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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, ... >>

Happiness from altruism is short-lived 18.03.2020

It is believed that altruism makes us happy, and there are a number of psychological studies in support of this. For example, if a person often helps someone, his mood improves, and when stressed, there is less emotional "negativity". Altruistic acts are also said to lower blood pressure and are generally good for health.

However, employees of the University of Bonn and Harvard University believe that happiness from altruism is not so simple: the initial "pluses" from it can turn into "minuses". The researchers invited about three hundred students to participate in two lotteries: one had a good chance of winning 100 euros, the other you did not win anything, but you could donate 350 euros to a fund for helping patients with tuberculosis. The participants in the experiment were free to choose which lottery they wanted to play, and the money in both of them was quite real. About 60% chose the second, altruistic, lottery, in which the money went to charity.

All participants in the lotteries filled out psychological questionnaires showing the level of happiness. Immediately after the lottery, as expected, those who chose the altruistic option were happier. However, the same psychological survey was conducted a month later - and now, after a month, the majority of those who played the altruistic lottery were less happy than those who chose money for themselves. That is, happiness from an altruistic act turned out to be short-lived and in the long run turned into a decrease in mood. Of course, anything could happen to a person in a month, but let's not forget that more than one or even ten people participated in the experiment, and the authors of the work probably took into account the likelihood of some everyday troubles that could happen to students.

The most curious thing happened to a small group of participants in the experiment who did not have to play the lottery: they chose the second, altruistic option, but they were told that the lottery was canceled and they were just given one hundred euros. An article in PNAS says that these people were happier than everyone else after a month. That is, for real happiness, it would be good if the altruistic impulse was reinforced by a reward.

It is possible that other types of altruism provide more stable happiness. After all, you can not only distribute money, you can help others yourself - help the elderly with disabilities, entertain orphans, etc. And it is possible that the altruism that involves direct social contacts will be more long-lasting.
