Libra with intelligence

28.10.2008

German engineers have created scales that themselves recognize what kind of fruit they put on them.

In order to weigh fruits or vegetables in a self-service store, you need to know their code - only after pressing the correct button, the scales will print out a piece of paper with a price. Somewhere the seller is engaged in this, but somewhere it was reduced and the buyer himself has to look for the code.

A balance created at the Fraunhofer Institute for Data and Information Processing can solve the problem. To do this, they are connected to a video camera, and a program for identifying fruits and vegetables is embedded in the electronic brains in accordance with the previously entered database. As a result, if a person buys tomatoes, then the scales will offer him several buttons with tomatoes and none with sweet peppers, no matter how red they are.

“At first glance, it may seem that this is a simple task,” says Sasha Vot, head of the work. “However, fruits and vegetables vary greatly in their shape and color. Even bananas can be green, yellow, and speckled brown. About the variety of colors of apples "Our algorithm is very stable against color and light fluctuations and it recognizes well the product placed on the scales. Now they are being tested in 300 supermarkets in Europe."

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, ... >>

Solar panels from lunar soil 14.02.2023

For decades, researchers have been talking about using lunar regolith as a material from which to create solar panels, because it contains all the necessary substances: silicon, iron, aluminum, etc. Since the Apollo mission brought lunar soil to Earth, there have been hundreds of thematic research papers and relatively modest engineering developments.

Blue Origin said that as part of its own two-year Blue Alchemist program, it learned how to make solar panels and electrical wires from a material that mimics the composition of moon dust.

Engineers at the space company Jeff Bezos used a process called "molten regolith electrolysis," where a material that mimics the composition of lunar regolith was supplied with a constant electric current at a temperature of 1600°C. Thanks to this, iron, silicon and aluminum were separated from the material. Blue Origin says it has produced silicon with a purity of over 99,999%.

By-products from the reaction also found use - they were used to make some elements of solar cells, as well as protective glass, which will allow devices to be on the surface of the moon for decades.

Such an approach would not only save lunar explorers the need to import the material, but it would also be environmentally friendly to use—no carbon dioxide emissions, no chemicals, and no water required.

Blue Origin recently created two separate divisions, one dedicated to space systems such as Orbital Reef, and the other exclusively to activities on the Moon. The company has been hiring dedicated people for years, and seems to be doing a lot of work behind the scenes, such as the Blue Alchemist project.
